Flow Rates: Generally range from 0.2 to 0.8 gpm – refer to performance curve. Actual flow may be higher and may vary from pump to pump. Due to this inherent characteristic, these pumps are not normally intended for metering.

Discharge Head: To 8.3 feet (on standard models).

Self-Priming: To 48 inches (on standard models).

Fluid Temperature: To 104°F (40°C).

Weight: Approximately 1 lb.

Motors: 115V, 230V 50/60 Hz – requires a diode (included with listed models).

Agency Approvals: Models on chart bear the UL Recognized Component Mark for the United States and Canada (except “Lab” models). FDA list materials for models listed in chart.

Materials in Contact with Solution

  • Glass-Reinforced Polypropylene
  • FKM
  • Butyl

Refer to the Chemical Resistance Section to help determine compatibility. (Use only elastomers with “A” rating for standard oscillating pumps.)

For aggressive-chemistry applications, contact GRI for special Glass-Ball Center Valve Oscillating Pumps (U.S. Patent 5,567,131).

OEM Options

If model meeting your exact requirements is not listed, please contact the factory and we will create your pump to meet your application requirements, exactly.

Valve Styles

To modify the priming or performance characteristics of the pump, two valve options are available: poppet valve or 2-piece valve.

The poppet valve provides the best priming capability and more positively prevents backflow through the pump.

The 2-piece valve should be used when flow is required.

Note: Valves are utilized on the discharge side of the pump. However, to more closely meet a customer’s specifications, valves can be used on both the inlet and outlet side.

Coils, Leads and Terminals

Generally, electrical coils are available in 115V or 220V and 60 Hz. However, pumps have been supplied with 115V or 220V, 50 Hz coils, and with 12, 24, and 48 volt AC coils. In addition, coils can be constructed with different power capabilities to more effectively meet customer’s duty cycle needs.

Leads can be up to 6 feet long with any termination. Most common are 6 inch leads with 1/4 inch made spade terminals.

Mounting Options

The oscillating pump can be provided with three mounting styles. The rubber mount design is more compact and less expensive: however, flow rate, priming capability and discharge head are lower than the spring mounted pumps. The spring mounted model is more efficient and transmits less vibration to the mounting structure.

Three Mounting Styles:

  • Rubber Mount
  • Spring Mount with Base
  • Spring Mount
