Chapter 1: System Description
Function and Theory
The Geotech Series I and II Peristaltic Pumps were designed for single and
multi-stage pressure or vacuum pumping of liquids for field or laboratory use.
Because they operate to a depth of 27 feet at sea level, they are ideally suited for
sample removal from shallow wells and all surface water sources. They operate
by mechanical peristalsis, so the sample comes in contact only with the tubing.
This allows for sample integrity as well as easy cleaning and replacement. With
the optional stainless steel tubing weight, tubing can be lowered to a specific
depth without curling or floating on the surface of the water. Differences between
the two models affect only the number of pump heads which may be used with
the Geopump at one time, and the speed or speeds at which the pump heads
operate. Therefore, instructions for general operations will be covered only once.
System Components
SE IES I Peristaltic Pumps are available in AC only, DC only, or an AC/DC
combination. These units have one pumping station which can also be piggy-
backed for multi-station pumping. They are variable speed from 60 RP to 350
RP .
SE IES II Peristaltic Pumps are available in AC only, DC only, or an AC/DC
combination. They have two pumping stations which can also be piggy-backed.
The first pumping station is rated at 30 RP to 300 RP and the second station
at 60 RP to 600 RP . Each pumping station works in conjunction with the
other.

Chapter 2: System Installation
Standard Pump Head Instructions
Separate pump halves. Hold the pump head as shown, with the rollers in the 2,
6, and 10 o’clock positions and the rotor shaft facing down.
Place the tubing around the rollers.
Turn rotor counterclockwise until tubing has completely surrounded the rotor.
Tubing is now in place. Position other pump half onto the motor shaft and snap
shut. Be careful not to pinch tubing between plastic halves.

Chapter 3: System Operation
The pump kit arrives packed in the hard shelled peristaltic pump carry case with
the pump head properly attached to the pump (purchased separately). See
section on pump parts.
To put into service:
Remove the pump from the case, be sure pump is turned “OFF” (red, open
circle)
For AC/DC combination units, plug in the appropriate power cord into the outlet
in the back of the pump & other end of the power cord into the power source.
Insert the tubing into the pump head.
Put one end of the tuning into the sample source (well, river, ditch, lagoon, etc.)
and the other end into the sample container.
Determine the desired direction of flow and turn the direction toggle switch in that
direction.
Turn the pump “ON” (the black filled circle).
When pumping has begun, the speed dial can be adjusted to the fluid pumping
speed desired.

Chapter 4: System Maintenance
Peristaltic Pump: aintenance Tips
The Geotech Peristaltic Pump has a strong reputation for durability and being
virtually maintenance free. These simple maintenance steps will assure your
pump’s long term reliability:
Pump Tubing:
Geotech recommends regular tubing replacement for optimum performance, use
of the proper size and type of tubing for the pump head is essential.
If you are unsure of tubing type for your application, please call Geotech.
Depending on the pump head design, different sizes of tubing may be used.
Use of the incorrect tubing size or type, will cause damage to the pump and/or
the pump head and void the warranty.
Pump:
Keep your Geopump clean and dry. In the event that the Geopump is subjected
to significant splashing or immersion, discontinue use and wipe the unit down
immediately with a clean dry cloth.
To keep your Geopump reliable follow these simple guidelines.
Do not drop your Geopump
Do not immerse your Geopump
Do not subject your Geopump to poor power supplies
Do not subject your Geopump to extreme heat or cold when in use
Power Cords:
Always replace any kinked or damaged power cord. Units with hard-wired AC or
DC power cords should be sent back to Geotech for proper repair (see pg. 12).
However, replacement power cords are available for AD/DC combination units.
Pump Head:
Your Geopump pump-head needs to be periodically cleaned with a Phosphate
free cleaning detergent and water solution.

Chapter 5: System Troubleshooting
Problem: Unit will not turn on
Solution:
No power to unit:(rollers not moving)
-check power source and compatibility
-check connections
Speed control not set fast enough to overcome tubing resistance:
-check speed setting; if too low turn it up
Check tubing size and type-make sure it is the correct size and type for the pump
head
Check circuit breaker; if tripped press it in to reset.
Problem: Unit turns on, but not pumping…(Pump head rollers are
moving)
Solution:
Verify fluid level in well (maxsuction lift unit can pump from 27’ below ground at
sea level).
Water level is below down well tubing intake-Increase tubing length.
If using a combination of flexible and rigid tubing check connection, between
tubing. A poor connection may cause a vacuum leak. Secure tubing connection.
Flexible tubing in pump head compromised or worn out:
replace flexible tubing regularly
Obstruction in tubing:
check for clogs and kinks
clear any obstructions
Using incorrect tubing type for pump head:
tubing may be collapsed.
replace with proper tubing type
Problem: Pump head rollers are not moving
Solution:
Pump head is loose from the pump housing:
tighten pump head screws to engage pump head to gear
Possible internal damage - call Geotech for consultation.
