EH-HV High Viscosity Pumps
Walchem and Iwaki have created a unique partnership with over 100 years combined pump experience in an array of different markets. 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 feed ranges from 2.3 GPH to 8 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. *Tested with 20,000 cps polymer verified with a Brookfield viscometer, Model LVF at 25°C, #4 spindle at 12rpm.
Specifically designed to accurately feed high viscosity chemicals.
Available in feed ranges from 2.3 GPH to 8 GPH and pressures up to 73 PSI.
Up to 240 strokes per minute results in high resolution chemical feed, reduced pulsation and improved mixing
- Stainless Steel or Hastelloy C276 springs help quickly close the valve balls against the PCTFE seats, increasing the valve action with high viscosity polymers.
- 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
- PTFE laminate over EPDM is molded onto a solid core. A retainer plate is engineered to minimize flow rate changes as pressure varies.
