Mini PVC Bladder Pumps
The 1.3-inch diameter pump can be installed in 2-inch and larger wells. The low stroke volume of 35 ml per cycle substantially reduces the fluid velocity at the pump inlet when compared to traditional bladder pumps. The high-efficiency design provides flow rates from 35 ml and allows sampling up to 200 feet. All pumps can be supplied contaminant-free.
Constructed of PVC, the pump uses a flexible squeeze-type internal bladder. Bladder life is rated at several million cycles. The pump can be dissembled should access be required. The rounded bottom inlet reduces the possibility of the pump hanging up during installation. Integral screened fluid entry ports allow for point source sampling. 1/4” Push-Lok fittings provide for quick and easy tubing connections.
Applications for Mini PVC Bladder Pumps include
- Specially designed for low-flow sampling
- Low flow groundwater purging and sampling
- 2 in Sch 40 and larger-diameter wells
A controller and an air source is required to operate the PVC Mini Bladder pump. We offer two models of Bladder Pump Controllers.

Locking Caps
Locking caps provide a convenient way to suspend bladder pumps in dedicated installations. The cap has an expandable gland that holds it firmly in place and seals the well to prevent entry of surface water or contaminants. The cap includes connections for a stainless steel suspension cable and fittings for tubing from the pump. A 0.75 inch port allows a water level probe to pass through so that water level measurements can be made.
