Geotech portable bladder pumps that these 1.66 inch bladders fit

Geotech Bladder Pump Bladders — 1.66"

Replacement bladders for the 1.66" Geotech Portable Bladder Pump. The bladder is the only part of the pump that contacts the sample, and it is a consumable — most programs fit a fresh one at each well to eliminate any possibility of carryover.

PTFE or polyethylene?

  • PTFE is chemically inert and the choice when the analyte list is sensitive or the method specifies it. It costs more per bladder but stands up to aggressive chemistry.
  • Polyethylene is inexpensive enough to treat as genuinely single-use. For routine monitoring across many wells, the 12-packs are the economical way to buy.

Running a PFAS-free pump? Fit the polyethylene bladders only. PTFE is a fluoropolymer and is not part of the PFAS-free build — see the PFAS-free parts list for the other components that differ.

Match the bladder length to your pump body — an 18" pump takes 18" bladders, a 36" pump takes 36".

Everything compatible with this diameter is in the 1.66" Bladder Pump System collection.
