"HV" High Viscosity Pumps

The Walchem EK Series pump is the world’s first and only IP67 rated electronic metering pump - guaranteed to operate submerged 3 feet under water for up to 30 minutes!  This makes the EK Series pumps ideal for wet or high humidity environments found in irrigation, agriculture, food & beverage, car wash or paper mill applications.

 

The EK Series are highly precise metering pumps with outputs to 6.7 GPH (25.2 l/h) and a maximum pressure of 150 PSI (10 bar).  The 360 stroke-per-minute operation results in high-resolution chemical feed and long service life.  Quiet and compact, EK pumps prime in seconds and hold prime reliably.

 

  • Standard Features:

    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.
