Oscillating Pumps

Product catalog summary

Overview: GRI Oscillating Pumps are self-priming, corrosion-resistant, and constructed from FDA-accepted materials. They are used in various applications such as film processors, medical equipment, and chemical mixing. Key features include dry run capability, quiet operation, and flexible mounting options.

Operation: The pump operates using an elastomeric impeller that moves through a spring and armature into an electric coil. A diode feeds impulses to the coil, causing the impeller to pump liquid. A valve prevents backflow.

Specifications: Flow rates range from 0.2 to 0.8 gpm, with a discharge head up to 8.3 feet and self-priming up to 48 inches. The pumps can handle fluid temperatures up to 104°F and weigh approximately 1 lb. They are available with 115V or 230V motors and require a diode.

Options: Two valve options are available: poppet valve for better priming and backflow prevention, and 2-piece valve for higher flow. Tubing connectors are made from glass-reinforced polypropylene, available in various sizes.

Mounting and Electrical Options: Pumps can be mounted using rubber or spring mounts. Electrical coils are available in various voltages and can be customized for different power needs. Leads can be up to 6 feet long with various terminations.

Series Specifications: The document details specifications for the 14825, 15000, and 17000 series, including flow rates, discharge head, self-priming capabilities, and materials in contact with solutions. Each series offers different features and options to meet specific application needs.

Oscillating Pumps Oscillating Pumps Overview 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. Typical OEM applications include film processors,...

Oscillating Pumps Valve Styles 2-Piece Valve Tubing Connectors Tubing connectors are made from chemicallyresistant, glass-reinforced polypropylene. Currently, 10 sizes and styles are available in any inlet/outlet combination. Required tubing size is listed with corresponding photo. Poppet Valve 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...
