Operating Principles
When the Solinst Double Valve Pump (DVP) is placed in a well or
borehole, water rises inside the pump and the twin tubes to static
level. A Control Unit is used to deliver compressed gas to the
pump. During the drive period the gas pushes down on the water
column contained in the drive line tubing, closing the check valve at
the base of the pump. This forces water up the sample line tubing.
A vent period, during which the gas is released, allows hydrostatic
pressure to refill the pump and drive line with sample water. The
top check valve prevents water in the sample line from falling back
into the pump body. This pressurization and vent cycle is repeated
manually or automatically as set by the timers on the Control Unit.
The cycle may be regulated for purging or sampling.
1.66 ” Double Valve Pump Operating Instructions
Model 408 SS and PVC 1.66”dia.
Notes: 1. The maximum lift for stainless steel (SS) pumps is 500 ft.
(150 m), and 100 ft. (30 m) for the PVC model.
2. DO NOT exceed an operating pressure of 250 psi for the SS
model and 50 psi for the PVC model.
3. The pump has been decontaminated before leaving Solinst
however, you may wish to decontaminate your pump before
use. The pump should be decontaminated between wells.
4. Tube fittings are based on use of 3/8" drive line and 1/4" sample
line. A 3/8" to 1/4" adaptor is also supplied,if dual 1/4" tubing
is preferred.
5. Refer to the operating instructions in the lid of the Solinst
Model 466 Control Unit for detailed pumping instructions.
Pump Operation
Portable: The Pump will be attached to skip-bonded, dual 1/4" OD
LDPE tubing, mounted on a reel.
a) For the stainless steel model, push the tubing inserts into the
end of the tubing and into the drive and sample compression
fittings of the DVP (the nuts of the compression fittings may
have to be loosened before inserting the tubing). Tighten the
nut 1-1/4 turns past finger tight for proper seal (see overleaf).
b) Lower the assembled DVP into the well, using a stainless steel
safety line. The Solinst Model 103 Tag Line can be used for
this purpose.
c) Connect the supply line with the in-line dryer from the
compressed gas source to the Control Unit. The drive line
connects from the Control Unit to the reel.
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 Pump will come with a roll of tubing to be cut to
length, as required, for attachment to a Wellhead.
a) Cut the tubing to desired length. See step a) above for tubing
connection instructions to the stainless steel Pump.
For the PVC model, attach the 1/4" sample tubing to the
compression fitting on the DVP and slide the 3/8" drive line
tubing onto the barbed fitting and secure with the single ear
Oetiker Clamp (see overleaf).
b) Attach the sample and drive lines to the appropriate Push
Fittings on the underside of the Wellhead.
c) Lower the DVP into the well, using a stainless steel safety line
if desired. If useful, attach the safety line to the suspension hook
on the underside of the Wellhead. Push the Wellhead firmly
onto the riser casing.
d) Attach a short (3 ft. or 1 m) length of 1/4" OD sample line to
the sample connector on the Wellhead. (See diagram at right
for use of Push Fittings.)
e) Connect the supply line with the in-line dryer from the
compressed gas supply to the Control Unit. The drive line
connects from the Control Unit to the top of the Wellhead.
f) For detailed pumping instructions, please see the Solinst Model
466 Control Unit Operating Instructions.

Notes:1. Always follow your local guidelines and standard protocols.
2. Do not use acetone on the O-rings.
Disassembly
1. Remove the Top Platen from the Pump Body and Riser.
Remove the Pump Body from the Bottom Platen and slide it
off the Riser.
2. Remove the Riser from the Valve Body, being careful not to
lose the Check Ball.
3. Remove the Valve Body from the Bottom Platen, being sure
not to lose the second Check Ball.
4. Remove the Filter Retainer from the Bottom Platen, and then
remove the Filter Mesh from the Filter Retainer.
Reassembly
1. Slide the Filter Mesh over the Filter Retainer until seated.
2. Thread the Bottom Platen onto the Filter Retainer until the
O-ring is seated and the parts are finger tight.
3. Insert a PTFE/FEP Check Ball into the top of the Bottom Platen.
4. Take the Valve Body and insert into the Bottom Platen until the O-
ring firmly seats.
5. Insert a PTFE/FEP Check Ball into the top of the Valve Body.
6. Insert the bottom end of the Riser (hole downward) into the Valve
Body.
7. Slide the Pump Body over the Riser and thread onto the Bottom
Platen.
8. Take the Top Platen and while lining up the top of the Riser
into the centre of the Top Platen, thread the Pump Body to
the Top Platen.
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 and
dry.
4. Replace worn O-rings as necessary, and then reassemble.
