The Stenner 170 Classic Series peristaltic pump is a double head adjustable output metering pump.

The Stenner 45 Classic Series peristaltic pump is an adjustable metering pump built with three detachable components: the motor, feed rate control, and pump head.

The output is not adjustable and is determined by the rpm of the motor gears and the size of the pump tube. The motor’s output shaft rotates at a fixed rpm which drives the roller assembly within the pump head.

The Stenner 85 Classic Series peristaltic pump is a single or double head pump.

The Stenner BDF Series peristaltic pump is an adjustable programmable 7-day or 24-hour metering pump built with a low rpm motor and a detachable pump head.

The S420 Series variable speed peristaltic metering pumps dose liquid solutions in direct proportion to a 4-20mA analog input signal.  The operator can scale the pump’s response to the signal from 25% to 100% by the potentiometer on the control pad. When operated in the manual mode the maximum flow rate output is adjustable from 5% to 100%.
