The workhorse of the E-Class - no other electronic metering pump can match the power and performance of  Walchem's EHE Series.

EHE pumps have outputs up to gallons per  hour and pressure capabilities from 30 to 150 PSI. Combining the EHE performance  and a turn-down ratio of 1800:1 yields one of the most versatile pumps on the  market today.

Superior mechanical design and quality of  manufacturing merge to create a pump better than the sum of its parts. The EHE  Series is ideal for chemical feed applications in a wide range of fields,  including water treatment, chemical process, municipal and industrial  wastewater.

Powerful
The EHE35 size pump is the most powerful electronic metering pump  currently available. A pump's maximum pressure rating times its maximum output  at that pressure gives a relative measure of the pump's hydraulic output power,  a "power index".

Control
Microprocessor-based circuitry provides the operator adjustment of  pump speed and external input settings via a 4-button keypad. The EHE comes with  digital and analog external mode control.
