The Gorman Rupp Industries (GRI) model # 15000-155 is a Oscillating Pump and Motor unit, coil spring mount, with 7/16 inch - 12mm ID Hose ports, coupled to a 115 Volt AC Motor. The oscillating pump is a low flow (between 0.2 to 0.8 GPM), low pressure (between 0 and 8 feet of head) transfer or circulating pump. The pump contains an elastomeric impeller that extends through a spring and armature and into an electric coil. A diode in the circuit feeds impulses to the coil 50 or 60 times per second. Each pulse draws the armature and impeller forward against the spring, pumping liquid through the outlet. The spring returns the armature and impeller to their original position, drawing liquid through the inlet. Oscillating Pumps are self-priming, corrosion resist
