Stenner Pumps

Stenner pumps come as either adjustable or fixed output metering pumps. Each pump has detachable components: the motor and pump head is standard and optionally a feed rate control on adjustable pumps. Outputs are dependent upon the rpm of the motor gears and the size of the peristaltic pump tube and on adjustable models the percentage setting on the feed rate control. The fixed rate pump has no output adjustment. All Stenner metering pumps have a 3-point roller design in the pump head, which acts as a check valve to prevent back flow, siphoning, overdosing and loss of prime.
