Features

- High Speed Operation: Up to 240 strokes per minute results in high resolution chemical feed, reduced pulsation and improved mixing.

- Adaptable Modular Design: Liquid end, drive and electronics are modular, enabling economical repair or replacement of parts. The control module can easily be mounted in a remote location.

- Spring Loaded Valve Action: Stainless Steel or Hastelloy C276 springs help quickly close the valve balls against the PCTFE seats, increasing the valve action with high viscosity polymers.

- Long Lasting Diaphragm: PTFE laminate over EPDM is molded onto a solid core. A retainer plate is provided to minimize flow rate changes as pressure varies.

The HV series is specifically designed to accurately feed high viscosity chemicals. Equipped with rugged, machined PVC or molded GFRPP liquid ends and spring-loaded stainless steel valve balls, the HV series is designed for superior valve action and performance.

Rated to 20,000 cps*, the HV series is available in two feed ranges from 2.3 GPH to 4 GPH and pressures up to 73 PSI. Sophisticated design and backed with the industry’s only full 2-year warranty, the EH-HV series is the perfect solution for high viscosity dosing applications.

EWN Series 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.

Two controller options provide various features, outputs and flexible pump control including scalable Analog control, Digital Input with Multiply and Divide capability, Batch control, external Stop, AUX and Interlock inputs, analog and alarm outputs as well as simple speed & stoke length control. Display can be adjusted between flow rate units, % speed or SPM for easy-to-read output and enables quick adjustment. The controller is universal voltage so it can be used anywhere in the world.

*Output rated w/20,000 cps polymer. Output increases with lower viscous fluids up to 25% with water.
