Geotech PVC Bladder Pumps 18” (91cm) & 36” (46cm) Installation and Operations Manual Rev 12/13/2012 Part# 11150188 Function and Theory Geotech’s pneumatic Bladder Pumps operate with a unique action, ideal for both, gentle low-flow sampling and high flow rate purging. Timed on/off cycles of compressed air alternately squeeze the flexible bladder to displace water out of the pump to the surface and exhaust allowing the pump to refill. Fluid enters the pump through the fluid inlet check valve at the bottom of the pump body, via hydrostatic pressure (automatically by submergence). The bladder then fills with fluid. Compressed air enters the space between the bladder and the interior of the pump wall housing. The intake check valve closes and the discharge check valve opens. The compressed air squeezes the bladder, pushing the fluid to the surface. The discharge check valve prevents back flow from the discharge tubing. Driven by the Geocontroller II or Geocontrol PRO, this cycle automatically repeats. Compressed air does not contact the sample! The bladder prevents contact between the pump drive air and the sample. Selecting an Air Source To determine the required capacity of the air source used, use the following chart as reference.

Generally, the more turbid or sandy your water, the more often you should maintain and clean your pumps. Disassemble the bladder pump per instructions, decontaminate or replace as needed, then reassemble. Inspect all check balls for wear and replace as necessary. Inspect all O-rings for splits or cracks and replace as necessary. Disassembly and Bladder Replacement Pull pump from the well, it is not necessary to remove the air and sample lines from the pump. Unscrew the lower cap from the housing, followed by removing the housing from the upper cap. Wrench flat features are present on both upper and lower caps. Unscrew the compression rings from the upper cap and lower head. Spanner wrench holes are located on the lower head to avoid spiral damage to the internal tube. Pull the bladder assembly out from the upper cap. The internal bladder cartridge can now be removed for maintenance or replacement. Please refer to the Components and Assembly diagram located on the inside of this manual for reassembly. 2 Item Qty Description Part No. 1 2 O-RING,VITON,#125,BROWN 17500120 2 2 O-RING,VITON,2.5MM X 23MM 11150319 3 2 O-RING,VITON,#014,BROWN 17500119 4 1 O-RING,VITON,2mm x 7.5mm,BROWN 16600108 5 2 BALL,VITON ,3/8, PVC BLADDER PUMP 1.66,TOP 17500115 6 1 HOSEBARB,CLEAR PVDF,1/8 NPT TO 5/32 BARB 11150187 7 1 HOSEBARB,POLY,MODIFIED,.25, PVC BLADDER PUMP 1.66 11150134 8 1 UPPER CAP,1.66,PVC,BP,CE 21150122 9 1 TUBE INTRNLSMPL,PVC,1.66BP,18" 11150124 10 2 RING,COMPRESSION,PVC,1.66,BP 21150115 11 1 BLADDER,PTFE,1.66"X18",PVC,CE 21150119 12 1 LOWER,HEAD,PVC,1.66,BP,CE 21150117 13 1 HOUSING,PVC,1.66X18",BP,CE 21150120 14 1 WEIGHT,SS6,INTERNAL,BP,PVC 11150132 15 1 PLUG,BALL RETAINER,1.66 PVC BP, CE 21150116 16 1 CAP,LOWER,PVC,1.66,BP,CE 21150114 17 1 SCREEN,INTAKE,1.66,PVC,BP,CE 21150118 18 1 CAP,SCREEN,INTAKE,1.3,PVC 11150131 19 1 CAP,LOWER,DROP TUBE,1.66,PVC, BP, CE 21150125 20 2 HOSEBARB,PP,1/2X3/8MPT 11150189 21 1 BODY,INTAKE,DROP TUBE,1.66,PVC, BP,CE 21150126 22 1 HOUSING,PVC,36",BP,CE 21150123 23 1 BLADDER,PTFE,1.66"X36",PVC,CE 21150124 24 1 TUBE,INTERNALSAMPLE,BP,36,PVC, 1.66X36 11150125 25 § ASSY,LOWER CAP,1.66 PVC,DROPTUBE,CE,WITH 1/2" HOSEBARB 51150072 26 § ASSY,INTAKE,1.66 PVC,DROP TUBE, CE,WITH 1/2" HOSEBARB 51150073 § KIT, 1.66, PVC, 0-RING SET, CE [ITEMS: #1(2), #2(2),#3(2), #4(1)] 91150018 1 MANUAL § SOLD SEPERATLY 3 4 Troubleshooting Cycling air with no sample •Adjust the controller charge/exhaust times properly. •Excessive drawdown may be preventing pump submergence. •Screen intake needs to be submerged at least 5ft deep. •Test cords and battery to ensure you have a sufficient power source. •Clean any debris that may be clogging the intake screen. Air bubbles present in sample •Replace any O-Rings and bladder if showing tearing or damage. •Repair or replace air and discharge lines if damaged or split. Discharge line draining back into pump •Remove the discharge hose barb and check ball and clean any debris in the check ball area.
