Well Wizard Bladder Pump Models
A Well Wizard® dedicated bladder pump system is an air-actuated bladder pump
that you permanently position in the well.
The pump is typically positioned with the pump inlet midway in the screened section of the
well, suspended by twin-bonded tubing that supplies air to the pump and conveys the water
sample to the well cap. Whenever possible, the pump systems are shipped already
preassembled to the tubing and the well cap assembly. Several different models of Well
Wizard® bladder pumps are available.
1000 Series Pump
Field service of the small diameter 1000 Series pump is generally not recommended as reassembly may
result in damage. Please contact QED Technical Support at 1-800-624-2026 or [phone] for more
information on how to service these pumps.
1100 Series Pumps
The 1100 Series pumps can be disassembled for field service and include 4 major components:
• Discharge assembly (PVC, stainless steel or Teflon®)
• Inlet assembly (PVC, stainless steel or Teflon)
• Bladder cartridge assembly (Teflon bladder or Well Wizard Zero non-fluoropolymer bladder)
• Pump Body (PVC, stainless steel or Teflon)
You can disassemble the major components of the pump without tools by unscrewing the inlet
and discharge assemblies by turning them counter-clockwise and pushing the bladder cartridge
out of the pump body. The bladder cartridge can be replaced as a complete assembly on
dedicated models; the bladder can be removed and replaced separately on portable models.
1200 Series Pumps
The 1200 series pumps can be disassembled for field service and include 2 major components
• Bladder and check valve assembly (either Teflon and stainless steel or PVC and
stainless steel)
• Pump Body (stainless steel)
The 1200 Series pumps bladders can be replaced and will require tools for disassembly (refer to
the instructions included with the field-replaceable bladder kit).
1300 Series Pumps
The small diameter 1300 series pumps require snap ring pliers to disassemble, and field service is generally
not recommended. Please contact QED Technical Support at 1-800-624-2026 or [phone] for
more information on how to service these pumps.
1500 Series Pumps
The P1500 pump is a longer version of the 1200 Series pump. This pump has two major components.
• Bladder and check valve assembly (either Teflon and stainless steel or PVC and
stainless steel)
• Pump Body (stainless steel)
The 1500 Series pumps bladders can be replaced but may require factory service; contact QED
Technical Support at 1-800-624-2026 or [phone] for more information on how to
service these pumps.

How a Bladder Pump Works
The bladder pump has two alternating cycles
called Discharge and Refill.
Discharge Cycle
During the discharge cycle, water within the pump is
pushed to the surface by pressurized air or gas delivered to
the pump through the air supply tubing. When the
pressurized air fills the chamber between the pump body
and the bladder, it squeezes the bladder, closing the
bottom check valve and lifting the upper check valve,
pushing water up the discharge tubing to the surface. When
the full volume of the bladder is discharged or the cycle is
ended by the controller, the upper check valve closes to
prevent water in the tubing from draining back into the
pump.
Figure 2

Well Wizard® Installation and Operation Manual Rev. E 06-05-2023
6
How a Bladder Pump Works
Refill Cycle
During the refill cycle, the pressurized air or gas within the
pump is vented back up to the surface through the air
supply tubing. When the air pressure within the pump falls
below the hydrostatic pressure, the bottom check valve
opens and allows water to enter the pump, filling the inside
of the bladder.
Caution: A Well Wizard® pump bladder can be damaged by
sand or solids. An inlet screen is recommended for all
applications, especially when the pump inlet is located close
to the bottom of the well. The Well Wizard 10-year warranty
does not apply if an inlet screen is not used.
Figure 3

Twin-Bonded Pump Tubing, Inlet Screens and Well Caps
Pump Tubing
A ground water sample is only as good as the tubing it runs through. Your Well Wizard® system should be
equipped with one of the following types of superior-quality tubing from QED:
• High Density Polyethylene (HDPE)
• Teflon® -lined polyethylene
• Teflon®
Most tubing is supplied as a bonded pair (air supply and discharge) to make installation easier
and help to prevent other equipment such as water level measurement tapes from becoming
entangled with the tubing.
Unless your order specified that you wanted bulk tubing, the tubing for your Well Wizard
bladder pump is pre-cut to the correct length for your well based on the well data you provided.
Inlet Screen
An inlet screen can protect the bladder in your Well Wizard pump by preventing sand from
contacting the bladder and ensure proper performance by keeping larger sand particles out of
the check valves. The use of an inlet screen extends the pump warranty to ten years.
Well Cap
The pump and tubing are connected to a well cap that support the weight of the system and
provides connections for the air supply and water discharge. There are two terminal fittings inside
the well cap (see figure 4 below).
• A compression style bore-through fitting for the discharge line.
• A brass quick-connect nipple for the pump air supply line.
There are a wide variety of well cap designs to accommodate the majority of well completion
designs, both above grade protective outer casing and at-grade vault boxes. Various designs
include recessed caps for low clearance applications in vault boxes, slip caps for use in outer
protective casings, locking caps to help prevent unauthorized access to the well, and sealing
caps to help prevent surface water from entering the well. Consult QED’s Customer Service or
Sales representatives to determine the best design for each well at your site.

MicroPurge® Portable Components
Portable MicroPurge® sampling system components include bladder pump cycle controllers, portable
compressor or compressed gas source, water level and drawdown limit meter, water quality
analyzers for purging parameter monitoring, and disposable sample filter cartridges.
MicroPurge Controllers
A controller operates the Well Wizard pumps by regulating the air flow from a compressed-gas source
to the pump. The controller alternately pressurizes and vents the air supply line to the pump, allowing
the pump to discharge and then fill with water. Different controller models include the MP10, MP10H
High Pressure 300 PSI and MP10UH Ultra High Pressure 500 PSI versions, designed to operate the
Well Wizard pumps to depths up to 1,000 feet (305 meters) using external compressors or
compressed gas cylinders. The MP15 backpack controller includes an integral 5 lb. CO2 cylinder for
remote monitoring locations where vehicle access is limited. The MP50 model incorporates a 12-volt
DC compressor that can be operated from a portable battery or vehicle battery connection. QED
Customer Service representatives or your local QED sales representative or distributor can help you
select the best model for your site.
Portable Compressors and Pressure Regulators
QED offers both 12-volt DC (Model 3020) and gasoline engine driven (Model MP40C) portable oilless
compressors for use with the MicroPurge controllers. Where compressed gas cylinders are preferred,
QED can supply either nitrogen or CO2 pressure regulators with quick-connect hoses that match up
with the pressure ratings of our MicroPurge controllers.
Water Level & Drawdown Meters
The Model MP30 Drawdown/Water level meter is a dual function water level tape that can be
connected to any of the QED cycle controllers to automatically limit water level drawdown during
purging and sampling.
The 6000 Series electronic water-level measurement tapes have both a light for visual indication of
water level and audio signal when the probe touches the water surface.
Water Quality Flow Cell Systems
The MicroPurge MP25 and MP25T water quality analyzers measure purging indicator parameters to
let you know when it’s time to collect samples. The multi-parameter instrument connects wirelessly
via Bluetooth to a smart phone, tablet or laptop display. QED’s PurgeScan software allows you to set
your purging parameter limits and then monitors your data to determine when purging is completed.
You can find additional details on the MP25 and MP25T at www.qedenv.com.
QuickFilter® Filter Capsules
QuickFilter cartridges are the original, in-line disposable groundwater filters, developed in
1982 to meet the stringent purity requirements of sensitive groundwater quality monitoring
programs. Made from the highest purity materials and available common pore sizes,
QuickFilter capsules connect directly to your sample pump discharge tubing to save time and
ensure sample accuracy.

Installing Your Well Wizard System
Before Going to the Field Site
1. Check the outside of each box for well ID numbers to locate the pump and tubing for each
well. Note that some components (e.g., drop tube inlet weights, inlet screens) may be in
separate boxes from the pump/tubing systems – look on all boxes for product descriptions
and part numbers to locate these items.
2. Open the boxes, then before unpacking any of the contents, put on a pair of clean protective
gloves. Check your shipment against your order confirmation sheet and packing list. Make
certain every component you ordered is there and familiarize yourself with how components
go together before you go to the field.
3. Locate the Well Wizard Installation Guide and O&M manuals for any MicroPurge controls you
purchased. Some components, such as well caps and inlet screens, are shipped with separate
installation instruction included.
4. Locate any spare parts packages (such as extra fittings) and special tools shipped with your order (such
as clamp tools or tubing cutters).
5. Where tubing is cut to length and attached to each pump, carefully remove the pump and tubing
assembly from the box, taking care to not kink the tubing. A label on the package provides the well ID,
cap model, and tubing length. You may need this information later, so save the label.
6. Open the packaging surrounding the pump and slide the protective plastic sleeve off the pump to allow
installation of the pump inlet screen or connection of the drop inlet tubing, where used.
7. Make sure you have the necessary tools and supplies before you begin. The installation instructions
included with some components should identify any specific tools that may be required. As a minimum, you
should have:
 8-inch and 10-inch adjustable wrenches
 Pliers – slip joint, needle nose and arc joint (e.g.,“Channellock”)
 1/4”, 9/32” and 5/16” sockets with handle (or nut drivers)
 Plastic tubing cutter
 Sharp utility knife (if permitted by site health & safety plan)
 pinch clamp installation tool for barb fitting clamps, if used (available from QED)
 Insulation stripping tool for plastic-coated pump support cable if used
 A water level tape or other means of measuring the depth to water and sounding well depth.
 A compressed gas/air source and pump controller for testing the pumps after installation.
 Field supplies - disposable gloves (glove material type based on site sampling plan), DI water, wipes
or paper towels, and plastic sheeting (in case a pump system must be removed or laid out for
installation)
NOTE: Always wear clean protective gloves before touching any of the down-well components
(pump, inlet screen, tubing and drop tube weight if used). Touching well components without gloves
could potentially contaminate samples obtained using the Well Wizard system.
NOTE: The protective plastic sleeve on the pump contains the pump purity certificate, which
includes the pump batch serial number. You may want to record the well ID and site name on each
tag and retain it for your records. It’s your proof that the pump has been tested and shown to be
contaminant free. If needed, you can contact QED with the serial number to obtain details on the
laboratory test results.

Starting the Installation
1. Measure water level and well depth to confirm data. These numbers should match the data you provided on
the QED Well Data Specification Sheets that were part of your order confirmation.
 Well depth is critical when the pump or drop tube inlet is installed near the bottom of the well, as silt
accumulation may prevent proper installation. If the well depth confirmation measurement shows that
the bottom of the well is shallower than the original data due to measurement error, a database error, or
possibly due to silt accumulation, the tubing length should be adjusted to raise the pump, as desired, or
the silt should be removed prior to installation. (See Pump Testing section below for more details and
suggested solutions.) NOTE: This determination should be made BEFORE BEGINNING PUMP
INSTALLATION to avoid the need to pull the pump.
 If the measured water level is lower than the data on the Specification Sheet, determine if the pump will
still be adequately submerged. It may be necessary to change the pump position by adding tubing to
achieve the desired submergence. In general, pumps should have at least 10 feet of submergence and
systems using drop tube inlets should have 25 feet of submergence over the pump. Call QED if you
have any questions about submergence requirements and pump placement for your specific
application.
2. Check the well cap fit before lowering the pump and tubing into the well.
 Determine that the cap you ordered is the correct size for the well casing diameter and there is adequate
vertical clearance below the protective outer casing lid or vault box cover.
 If the cap does not slip easily onto or into the casing, there may be burrs or rough edges on the
edge of the casing. Use an appropriate tool to remove these before installing the system.
 With the cap installed, there should be sufficient clearance between the top of the cap and the
bottom of the vault cover or outer locking casing lid. If there is insufficient clearance, an alternate
cap design may be required (e.g., low clearance cap), or the well casing can be cut down to
increase the clearance in some cases. Contact a QED application specialist to discuss cap options.
 Be sure to account for the change in the water level measurement reference point elevation (top of
casing) due to the added thickness of the well cap. This should be recorded on a field form and
entered into the elevation database.

Installing the Bladder Pump Inlet Screen
Inlet screens extend the life of the pump, protect the bladder from damage by sand or other solids,
and help to prevent clogging and malfunction of the check valves in the pump.
Well Wizard bladder pumps equipped with an inlet screen carry a 10 year warranty on PTFE Teflon
bladder models and a 5 year warranty on Teflon-free bladder Zero models. Well Wizard pumps
installed without inlet screens are covered by a one year warranty.
 Well Wizard 1000, 1200 and 1500 Series pumps have inlet screens that attach to an internal
female pipe thread in the pump inlet housing.
 1100 Series plastic pumps (PVC or Teflon) use a slotted screen that attaches to external
threads on the pump inlet housing.
 1300 Series pumps have an integral inlet screen that is fastened to the pump using set screws
that lock into a groove above the pump inlet.
Inlet Screen Installation for 1000 Series Pumps
1. Open the plastic wrapping and remove the screen.
2. Holding the pump inlet housing with an open end or adjustable wrench, thread the screen into the
female thread in the inlet housing.
NOTE: Failure to hold the pump inlet with a wrench while installing the screen could result in
damage to the pump bladder assembly inside, which is not covered under the product warranty.
Inlet Screen Installation for 1100 Series Pumps
1. Open the plastic wrapping and remove the screen.
2. Thread the screen onto the external male thread on the pump inlet housing and tighten firmly by
hand only. Do not use tools to tighten the screen.
Inlet Screen Installation for 1200 and 1500 Series Pumps
1. Open the plastic wrapping and remove the screen.
2. Thread the screen into the internal female thread on the pump inlet housing and tighten firmly by
hand only. Do not use tools to tighten the screen.
Inlet Screen Installation for 1300 Series Pumps
1. The inlet screen on the 1300 Series pumps comes installed at the factory.
2. If replacement of the inlet screen is necessary, loosen the set screws located just above the pump
inlet, slide the screen over the inlet, then tighten the set screws to retain the screen.

Installing or Replacing Pump Fittings and Connectors
The following sections describe how to install or replace the three types of connectors that may be
included in your Well Wizard system. Well Wizard pump models use either stainless steel or
polypropylene compression fittings or barb fittings with clamps for pump tubing connections. Please
follow the appropriate instructions for the fitting type used on your pump model.
Stainless Steel Compression Fittings
Stainless steel compression fittings, which include four pieces come to you completely
assembled, finger tight.
Note: Be careful not to fully disassemble compression fittings before use to avoid losing the ferrules
or getting dirt or dust inside the fittings, which can make them difficult to tighten and result in leaks.
Note: When using compression fittings, if the discharge tubing is 3/8 inch OD or larger, a tubing
insert is recommended to ensure a tight grip on the tubing by the compression fitting. If the
discharge tubing is Teflon-lined PE tubing, you must use a tubing insert to prevent water from
getting between the inner and outer tubing walls.

Well Wizard® Installation and Operation Manual Rev. E 06-05-2023
15
Attaching and Re-Attaching Pump Fittings and Connectors
Stainless Steel Compression Fittings
Pumps may be shipped with tubing pre-assembled and attached to the pump for shallow wells (up to
200 feet/60 meters of tubing) or may have tubing bundles or spools shipped separately for deeper
wells with tubing longer than 200 feet/60 meters. Where the tubing has been preassembled and then
disconnected from the pump, the fitting nut and sealing rings call “ferrules” should be attached to the
tubing bundle/spool.
New connections (pump and tubing shipped separately and not previously assembled):
Fully insert the tubing into the fitting until it bottoms out on the shoulder inside the fitting. The length of tubing
inserted into the fitting should be 0.80” (20 mm) for 1/2” OD tubing, 0.67” (17 mm) for 3/8” OD tubing and
0.50” (12.7 mm) for 1/4” OD tubing. Rotate the nut clockwise (when viewed from the top) until the nut is finger
tight.
Reconnecting tubing with attached nut and ferrules (tubing previously pre-assembled and shipped
in separate bundle or spool, or any removal of a fitting for service):
Stainless steel compression fittings can be reassembled as often as needed.
Connect the tubing to the fitting and finger tighten. Holding the fitting body steady with a wrench, turn
the nut clockwise (when viewed from the top) until you feel resistance, then tighten a quarter turn.

Well Wizard® Installation and Operation Manual Rev. E 06-05-2023
16
Polypropylene Connector
To install a polypropylene connector, follow these steps:
Cut the tubing cleanly and squarely to length.
Push the tubing into the completely assembled connector until it contacts the shoulder inside the fitting (see
figure 7).
Tighten the nut with a wrench, but be careful to not over tighten it; the nut should not come in contact with the
shoulder of the body (see figure 7).

Well Wizard® Installation and Operation Manual Rev. E 06-05-2023
17
Installing Pump Systems with Pre-Cut & Assembled Tubing
Well Wizard systems are most often supplied with the tubing cut to length for each well and
connected to the bladder pump, with each pump and tubing assembly tagged with the well ID
number provided. These systems are easier to install and can often be installed by one person,
but QED recommends two people for more efficient installation.
Generally, pump tubing lengths up to 200 feet (60 meters) will be attached to the pump and
shipped as an assembly. The well cap will also be pre-assembled onto the tubing unless
specified to be packaged separately.
On 1100 and 1200 Series pumps that use compression fittings, tubing lengths greater than 200
feet (60 meters) are pre-assembled onto the pump to swage the fitting ferrules onto the tubing,
The fittings are then removed and the tubing is packaged separately as a bundle or spool of
tubing. Follow the instructions on page 17 on Installing or Replacing Pump Connectors to
determine how to properly re-attach and tighten fittings prior to pump installation.
If your Well Wizard system was ordered with pre-cut tubing but the tubing has not been pre-
assembled with the pumps by request, skip down to the instruction below under “Installing Pump
Systems with Bulk tubing” for information on how to connect each pump model to its tubing
bundle.
1. Slowly lower the pump into the well while uncoiling the tubing bundle, until the entire length
of tubing is in the well. Be sure to control the rate of descent. Do not let the tubing free fall
into the well.
2. An optional support cable is recommended for the ST1102 and ST1102M pumps and is
available for all sampling pump models. Support cables are strongly recommended for
deep wells (generally deeper than 300 feet/ 90 meters). See pages 21-23 on installing
support cables.
3. To attach the well cap, separate about 8-12” (20-30 cm) of the twin-bonded tubing. Push
the discharge tubing through the compression fitting on the cap to the appropriate height
based on the cap design. Refer to the separate instruction sheet included with the well cap.
NOTE: During installation, be sure not to let the tubing or other pump components contact the
ground or any other surface that isn’t a known clean surface to avoid the risk of contamination.
It’s often helpful to spread out a clean plastic tarp next to the well during installation.

Well Wizard® Installation and Operation Manual Rev. E 06-05-2023
18
If your Well Wizard system was ordered with bulk tubing, it will be necessary to measure the
tubing length in the field or to install the pump using tubing known to be longer than the well
depth, cutting the tubing off when the pump is at the desired depth. Below are instructions for
connecting the tubing to each pump model.
Pumps with compression style fittings – 1100 and 1200 Series models
1. Separate the ends of the twin-bonded tubing about 8-12 inches (20-30 cm).
2. These pumps use a discharge fitting that is taller than the air fitting connection. Shorten the
length of the discharge tubing by measuring the difference between the fitting heights and cutting
off this amount from the discharge tubing. Alternately, you can insert the air tubing into the fitting
and then cut off the appropriate length of the discharge tubing, generally to the center of the fitting
height. It’s best to test fit the tubing for length before tightening the fittings.
3. If the discharge tubing is 3/8” O.D. or larger, or if it has a Teflon lining, you must use a tubing
insert. Push the insert into the tubing before inserting the tubing into the fitting.
4. Loosen the nut-and-ferrule assembly and push the air supply tubing into the matching fitting on
the top end of the pump.
5. Tighten both fitting nuts finger tight.
6. For each fitting nut, hold the fitting base with one wrench and the fitting nut with another wrench,
then tighten the fitting nut one additional turn.
Pumps with barb style fittings – 1000, 1300 and 1500 Series models
1. Separate the ends of the twin-bonded tubing about 8-12 inches (20-30 cm).
2. For pumps that have staggered height air and discharge fittings, shorten the length of the
discharge tubing by measuring the difference between the fitting heights.
3. Place the stainless steel pinch clamps onto the ends of the air supply and discharge tubing
BEFORE pushing the tubing onto the barbs.
4. Install each tubing by pushing it over the barb fittings as far as possible, and then position the
clamp over the barb and tightening the clamp with the pinch clamp tool.
Cut Bulk Tubing to Length
Measuring tubing length can be difficult under field conditions. Some users prefer to attach the pump to a
bulk tubing spool that is known to be longer than the well depth and then cut off the tubing when the pump is
installed to the desired sampling depth. However, this approach requires having more tubing that required for
the desired sampling depth. To determine the desired pump position, follow these steps:
1. Before using this method, check the well construction log or other documentation to determine if
there is a “tailpipe” or sediment trap installed below the well screen. If so, it’s recommended to
sound the well bottom depth before installing the pump system.
2. Lower the pump into the well until the pump touches the bottom of the well.
3. To position the pump at the middle of the well screen, where the screen extends upward from the
bottom of the well and the length of the screen is known, pull the pump up by half of the screen
length and mark the depth.
4. For low yield wells and/or wells with short water columns, raise the pump up at least 12 inches
(30 cm) from the bottom and mark the depth.
