EWN-R Series Metering Pump

The flexibility of the EWN-R pump enable it be integrated into virtually any chemical feed application using a universal-voltage, digital controller with an expanded set of control features.

Superb valve performance and advanced solenoid engineering combine to make a highly precise pump for the most demanding applications. EWN pumps have outputs to 6.7 GPH (25.2 L/h) and a maximum pressure of 290 PSI (20 bar). The high speed of operation results in high resolution chemical feed and long service life. Quiet and compact, the EWN pumps prime in seconds and hold prime reliably.


Note 1: Maximum output capacity shown is at Maximum Rated Discharge Pressure (stroke length 100%, stroke rate 100%) and increases as a discharge pressure reduces.
Note 2: Maximum Useable pressure rating is the maximum useable capability of the pump. Maximum output capacities may be lower than published at pressures higher than Maximum Rated Discharge Pressure. Maximum pressure of PVC type is 174 PSI. Please contact your distributor for more information.
Note 3: The performance is based on pumping clean water at ambient temperature at rated discharge pressure and voltage.
Note 4: Liquid temperature: PVC liquid ends: 14 to 104°F (-10 to 40ºC) GRFPP/PVDF/SS liquid ends: 14 to 140°F (-10 to 60ºC)
Note 5: Ambient temperature: 32 to 122°F (0 to 50°C) Relative humidity: to 85% (non-condensing)
Note 6: All pumps include a manual air vent valve except FC/SHN/HV models. All pumps include one foot valve, injection valve, 20 ft. of PE tubing and ceramic weight except for SH/H2/HV models.
