Iwaki Chemical EHE Series Feed Pump, 20.0 GPH, 30

Code: EHE-56E1-FC

Product Type: Pumps

Item Type: Chemical EHE Series Pump

Brand: Walchem


EHE is the workhorse of the E-Class metering pumps. Superior mechanical design and quality of manufacturing merge to create a pump greater than the sum of its parts. EHE pumps have outputs up to 20 GPH (76 l/h) and a maximum pressure of 150 PSI (10 bar). Combining the EHE performance with a turndown ratio of 1800:1 yields one of the most versatile pumps on the market today. EHE Series is ideal for chemical feed applications in a wide range of fields, including drinking water, agriculture, and municipal/industrial wastewater.



EHE pumps meet the demands of applications requiring accuracy over a wide output range. The 1800:1 turndown ratio provides the ability to accurately control a high capacity pump to very low outputs, without compromising accuracy. This enables oversize pumps to be installed in applications where output requirements fluctuate, or to accommodate future system growth.


Microprocessor-based circuitry provides operator adjustment of pump speed and external input settings via
4-button keypad. EHE comes with digital and analog external mode control. The external digital input mode features pulse multiply and divide circuitry that is often used in flow proportional systems, such as with a flow meter contactor. The external analog input mode is a programmable 4-20mA input that provides scalable speed adjustment based on any analog signal.
