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.
- It can handle capacities up to 528 gph (2000 lph) and back pressures to 200 psi. A double simplex arrangement is available for capacities up to 1056 gph.
- Three piston sizes and four stroking speeds assure a pump sized for your application without sacrificing operating range.
- The Chemtube 2000 utilizes a variable eccentric to provide for a smooth, non-loss-motion stroke adjustment.
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 use 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.
