The E Series Pumps run at 360 pulses per minute (PPM). Most of our competitors’ products run at 180 PPM or less, leading to faster wear and tear of the diaphragm and poor chemical injection control.

The EWN-C21TCUR Pump reaches a capacity of 2.1 GPH (7.57 LPH) at a maximum pressure of 150 PSI (10 bar). Compact, powerful and equipped with several types of control, this pump is designed for all dosing applications.
