EZ Series electronic metering pumps offer precise chemical injection at a low cost. The compact size and simple control make them ideal for water treatment and OEM applications.
Advanced microprocessor control and a turndown ratio of 360:1 make this series an exceptional value. The pumps are simple to operate with only three pushbutton keys and the unmatched turndown ratio provides both versatility and high resolution chemical feed which eliminates slug-feeding effects.
All E-Series pumps feature dual bearing support. The armature and shaft are supported with a bearing on each end, which ensures proper axial movement, enabling the E-Series to operate at 360 SPM while extending the life of the diaphragm.
Dual Check Valve Assemblies in both suction and discharge fittings feature precision ball guides and tapered seats. Precise machining and molding of parts limit valve ball travel, ensuring that balls fully seat and seal with every stroke. This superior check valve design guarantees fast priming and reliable performance.
EZ pumps had a design change of the liquid end as of July 1, 2015.

Can I use the EZ pump to produce an output based on water flow rate?
Yes. You first need a flow meter that sends a digital signal such as the MJN series, IP series, or any flow meter with an output less than 1000 Hz. Then you send the signal to a pulse accumulator such as the PT35 or a Walchem W100 controller. The device can then be programmed to turn a set number of pulses into a pump/relay on-time in seconds.
