Product Description:

The EHE is the workhorse of the E-Series metering pumps. EHE Series pumps have outputs up to 20 GPH (75 l/h) and pressure capabilities to 150 PSI (10 bar). Combining the EHE performance with a turndown ratio of 1800:1 yields one of the most versatile pumps in the water treatment industry today. Superior mechanical design and quality manufacturing merge to create a pump better than the sum of its parts. The versatile control features enable the EHE to be integrated into virtually any chemical feed application. The 360 strokeper-minute operation results in high resolution chemical feed and long service life. EHE pumps prime in seconds and hold prime reliably.


The wide range of capabilities within the E-Series ensures that there’s a model to fit any water treatment, food & beverage, agriculture, water conditioning, car wash, or other industrial chemical feed application.
