Operating Principles
When the Solinst Bladder Pump is placed in a well or borehole,
water rises inside the bladder and sample tubing to static level.
Compressed nitrogen or air is supplied to the pump via the
drive tubing using a control unit. Applying pressure causes the
bladder to compress and closes the bottom check valve, forcing
water from the bladder into the sample tubing.
During a vent cycle the pressure is released from the drive
tubing. The bladder returns to its initial state as water re-enters
the pump, while the top check valve prevents water already in
the sample tubing from falling back into the bladder. Cycling
the drive and vent provides water flow, the rate of which can be
adjusted for purging or sampling.
Notes: 1. The maximum depth for 1" Bladder Pump operation is
500 ft. (150 m) below grade.
2. DO NOT exceed an operating pressure of 250 psi.
3. Air dryers are recommended, if using a compressor to
operate the Bladder Pump.
Pump Assembly
Portable: The Bladder Pump can be connected to skip-bonded,
dual 1/4" OD tubing, mounted on a reel.
a) Push the drive and sample tubing over the tubing barbs on
the stems. The drive tubing connects to the stem identified
by a small dimple/indent beside it.
b) Lower the assembled Bladder Pump into the well, using a
stainless steel safety line connected to the eye safety stem
on the pump. The Solinst Model 103 Tag Line can be used
as a safety line if required.
c) Connect the supply line from the compressed gas source to
the Control Unit. The drive line connects from the Control
Unit to the reel (drive and supply lines come with the Model
464 Control Unit).
d) Attach a short (3 ft. or 1 m) length of 1/4" OD sample line
to the sample connector on the reel.
Dedicated: The Bladder Pump is assembled by connecting to a
Dedicated Wellhead with 1/4" OD sample and drive line tubing.
a) Cut the tubing to desired length. Push the drive and sample
tubing over the tubing barbs on the stems. The drive tubing
connects to the stem identified by a small dimple/indent
beside it.
b) Attach the sample line and drive line to the appropriate
push fitting on the underside of the Wellhead (see diagram
at right for use of push fittings and adaptors).
c) Lower the Bladder Pump into the well using Kevlar cord
or a stainless steel safety line connected to the suspension
hook on the Wellhead, if desired. Push the Wellhead down
firmly onto the riser casing.
d) Attach a short (3 ft. or 1 m) length of sample line to the
sample fitting on the Wellhead (see diagram at right for use
of push fittings and adaptors).
e) Connect the supply line from the compressed gas supply to
the Control Unit. The drive line connects from the Control
Unit to the top of the Wellhead (drive and supply lines come
with the Model 464 Control Unit).
For detailed pumping instructions, please see the Solinst
Model 464 Control Unit Operating Instructions.

Wellheads come with three 1/4" push fit adaptors
so that either 1/4" or 3/8" tubing can be used, as
preferred.
To attach tubing just push into push fitting.
To release tubing push down on both sides of the top
ring and pull tubing out.

Disassembly
1. Remove the Filter Retainer, Filter Screen and Top and
Bottom Platens, being careful not to lose the Check Balls.
Remove the Bladder Sleeve from the Pump Body.
2. Remove the Top and Bottom Retainers from the Bladder
Sleeve. While gripping the Bladder Sleeve, you may need
to push one end onto a solid surface to help get the first
Retainer out, then use the Center Rod to push the other
Retainer out. Slide the Center Rod out of the Bladder.
3. Remove the Bladder from the Bladder Sleeve using a pair of
needle nose pliers.
Decontamination
Notes: 1. Always follow your local guidelines and standard protocols.
2. Do not use acetone on the O-rings.
1. Completely disassemble the Pump.
2. Wash all pump components with phosphate-free soap or a
detergent.
3. Rinse all components thoroughly with deionized water.
4. Replace any worn O-rings and Bladder if necessary,and
reassemble.
5. The Pump’s interior can be cleaned without disassembling by
flushing your cleaning solution up and through the Pump’s
intake. With the Pump’s Filter removed, use a peristaltic
pump connected to the Bottom Platen, to push the cleaning
solution through the Pump. Then flush the Pump with
deionized water.
Reassembly
1. Manually slide the Bladder into the Bladder Sleeve. It will
extend beyond the Bladder Sleeve at both ends.
2. Using your finger, flare both ends of the Bladder.
3. If necessary install new O-rings on both Top and Bottom
Retainers and both Platens (8 in total).
4. Slide the Bladder so about 1/4" extends beyond one end of
the Bladder Sleeve. Hold the other end of the replacement
Bladder to minimize slip within the Sleeve. Liberally lubricate
a Retainer with water, and insert it first at a 45° angle and
rotate gently back and forth until the Bladder has been
pushed about 1/4" past the second O-ring on the Retainer.
5. Insert the Centre Rod into the Sleeve and ensure it seats in
the Retainer.
6. Trim the Bladder at the other end so it extends at least 1/4"
beyond the Bladder Sleeve. Lubricate the second Retainer
with water, insert it at a 45º angle then align it onto the
Centre Rod. Working gently to avoid twisting or crumpling
of the Bladder, push the Retainer into the Bladder until the
Center Rod is fully seated in both Retainers and the Bladder
has been pushed about 1/4" past the second O-ring on the
Retainer.
7. Using a sharp knife, trim any excess Bladder material so it is
flush with the edges of the Bladder Sleeve on both ends.
8. Take the Bottom Platen and drop the 5/16" OD Teflon
Check Ball into it. 1" Stainless Steel Bladder Pump
9. Fit the end of the bladder assembly firmly into the Bottom
Platen.
10.Slip the Pump Body over the assembly and screw it onto the
Bottom Platen.
11.Drop a Check Ball into the Top Platen and screw the Pump
Body onto it.
12.Shake the assembled pump to hear if the Check Balls rattle.
If not, repeat steps 8 to 11, to ensure that the Check Balls
are positioned correctly.
13.Fit the Filter Screen onto the Bottom Platen and screw the
Filter Retainer into place.
Note: The pump has been washed before leaving Solinst, however, you
may wish to decontaminate your pump before use. The pumping
assembly should be decontaminated between wells. Safety Line
