Series E Alta Viscosidad

High Viscosity Pumps



Max. Capacity 4 GPH

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 feed applications.

  • High Speed Operation
    Up to 240 strokes per minute results in high resolution chemical feed, reduced pulsation and improved mixing.
  • Spring Loaded Valve Action
    Stainless Steel or Hastelloy C276 springs help quickly close the valve balls against the PCTFE seats, ncreasing the valve action with high viscosity polymers.
  • 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.
  • 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.
