The Chemtube® 2000 metering pump is a high capacity hydraulically actuated, tubular diaphragm metering pump designed for long service under the severest conditions. It gives accurate metering of a wide variety of chemicals for any process application.

The pump's output can be controlled by varying the stroke length or stroke frequency. Stroke length control can be varied manually or through an automatic stroke length control. For precise and accurate feed rate control via stroking speed, an SCR Drive or Variable Frequency Drive can be used to vary the speed of the motor. Stroke frequency can be regulated manually by potentiometer setting or automatically via a 4-20 mA process variable input signal.

Repeatable metering accuracy is 1% of full scale, at constant hydraulic conditions, over a 10:1 range.
