Product Announcement from GRI Pumps (A Gorman-Rupp Company)


Oscillating Pumps-Image

Oscillating pumps are self-priming, corrosion resistant, have no dynamic seals and are constructed from FDA accepted materials.

Oscillating Pump Operation: 

An elastomeric impeller extends through a spring and armature and into an electric coil. A diode in the circuit feeds impulses to the electrical coil 60 times per second. Each pulse draws the armature and impeller forward against the spring, causing the impeller to pump a volume of liquid out through the outlet port. The spring then returns the armature and impeller to their starting position, drawing liquid through the inlet. A valve in the impeller prevents backflow of liquid.

Pump Specifications:

  • Flow Rates — Generally range from 0.2 to 0.8 gpm. Flow rates may vary from pump to pump. Due to this inherent characteristic, these pumps are not normally intended for metering.

  • Self-Priming — To 48 inches (on standard models)
  • Fluid Temperature — To 104°F (40°C)
  • Weight — Approximately 1 pound
  • Motors - 115v, 230v 50/60 Hz

Materials in Contact with Solution: EPT/EPDM & Glass-Reinforced Polypropylene.

OEM Applications:
