Bladder Removal Steps (all models)
1. Remove the bottom intake assembly and outer housing by turning the housing
counter-clockwise.

Use your hand or a strap wrench

If the pump does not easily come off, use the wrench flats on the cap to
provide leverage. The housing should twist/slide off (1.66 models).

DO NOT grip the hose barbs.

For .85 and .675 models, use a wrench that is one size bigger than the
bolts on the hose barbs. (EX: use a 7/16 wrench on a .850 model)
o
DO NOT grip the hose barbs.
o
Using a larger wrench will prevent the hose barbs from being
removed. The tool should only be used for leverage to loosen
the part.

If the bottom intake is difficult to remove, remove the snap ring, disc,
and screen and then use a wrench for removal.

Geotech uses black Buna-N O-rings for the PFAS free portable bladder
pumps. If you receive an O-ring from Geotech that is not black, do not
use the O-ring on the bladder pump and contact a Geotech
representative. Using incorrect materials while testing for PFAS
compounds will contaminate testing samples.
