Oscillating Pumps

Product Overview

Oscillating pumps are self-priming, corrosion resistant, have no dynamic seals, and are constructed from FDA accepted materials. Oscillating pumps are intended for replenishing, transfer, and circulating applications.

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.

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.

Motor: 115V 50/60 Hz 

Agency Approvals: Most models listed in charts provided herein bear the UL Recognized Component Mark for the United States and Canada (except 14925 Series “Lab” models).

Most models also have FDA listed wetted materials of construction for use in food consumable applications. NSF materials are also available.
