Centrifugal Pumps Product Overview Centrifugal Pumps are designed to transfer both corrosive and non-corrosive fluids at maximum hydraulic efficiencies. Centrifugal Pumps are not self-priming and must be used in applications where flooded suction exists. These pumps cannot be run dry. GRI specializes in the custom design and manufacturing of fluid pumps for the OEM market. The chart below is a general overview of GRI’s Centrifugal Pumps. If you do not find a pump that meets your exact requirements, our dedicated Sales Team will work with you to create a solution specific to your application - whether it is customizing an existing pump or designing new.

Compact Bellows Metering Pumps Product Overview Gorman-Rupp Industries’ line of Compact Bellows Metering Pumps were specifically designed for metering applications requiring low discharge pressures. Compact Bellows utilize GRI’s proven proprietary blend of polypropylene materials to provide an accurate and economical, long-lasting metering pump. A wide selection of valve and O-Ring elastomers produce chemical resistance pumps capable of handling both corrosive and non-corrosive fluids. The Compact Bellows Metering Pumps operate on a positive displacement principle. The rotation of the motor shaft is transmitted into an up and down linear motion through an adjustable concentric crank mechanism. This motion provides a continuous compressing and relaxing force on the bellows module, forcing fluid between two check valves located in the module’s valve body. Up to four separate bellows modules can be operated by single motor for proportioning up to four separate fluid mediums. The flow rate of each module is independently adjustable. Multiple bellows modules operate out-of-phase with each other for most efficient power usage. Any combination of ½”, ¾”, 1″, 1-1/2″ and 2″ bellows may be used in a pump. However, the total output must be limited to a maximum flow rate of 3000 ml/min.

Pocket Bellows Metering Pumps Product Overview Pocket Bellows Metering Pumps are the most economical metering pump on the market while maintaining the high quality standards of a Gorman-Rupp Industries product. Pocket Bellows are ideal for low flow, low pressure metering applications where a fixed flow rate is required. The Pocket Bellows Metering Pumps operate on a positive displacement principle. The rotation of the motor shaft is transmitted into an up and down linear motion through a concentric crank mechanism. This motion provides a continuous compressing and relaxing force on the bellows module, forcing fluid between two check valves located in the module’s valve body. Like the Mini Bellows Metering Pump line, the Pocket Bellows are constructed of plastic and uses GRI’s time-proven bellows technology. Pocket Bellows provide OEMs with an accurate, chemically-resistant, long-lasting metering pump at an economical price. The only difference between the Mini Bellows and the Pocket Bellows is that the Pocket utilizes a fixed crank mechanism.

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.
Gear Pumps Product Overview Gear Pumps are designed primarily for metering and transfer applications. Their modular design allows a wide variation of flow ranges with a standard parts set. Gear Pumps are self-priming and are “constant flow” pumps when RPM and differential pressure are constant. The materials of construction for bodies, gears and seals, provide a wide range of fluid compatibility. For more details, please click the blue
Magnetic Drive Pumps Product Overview Magnetic drive centrifugal pump operation is similar to a standard centrifugal pump except the motor shaft seal is removed resulting in the elimination of leaks caused by shaft seal failure. Magnetic drive centrifugal pumps must be used where flooded suction conditions exist. GRI specializes in the custom design and manufacturing of fluid pumps for the OEM market. The chart below is a general overview of GRI’s Magnetic Drive Pumps. If you do not find a pump that meets your exact requirements, our dedicated Sales Team will work with you to create a solution specific to your application - whether it is customizing an existing pump or designing new.
Standard Bellows Metering Pumps Product Overview The Standard Bellows Metering Pumps operate on a positive displacement principle. The rotation of the motor shaft is transmitted into an up and down motion through a lever pivot crank mechanism. This motion provides a continuous compression and expansion force on a bellows module, forcing fluid in and out of the module. Discharge pressure is maintained over the entire flow range of the pump. Standard Bellows Metering Pumps are designed to displace both corrosive and non-corrosive fluids. Accurate to ± 0.5% from stroke to stroke, when pump is set 50% to 100% of full stroke. Discharge pressure is maintained over the entire flow range of the pump. Poppet valves are used to prevent backflow; and springs are available to provide a positive shutoff, preventing siphoning through the pump in applications where a positive suction head exists. Bellows pumps utilize GRI’s proven proprietary blend of polypropylene materials to provide an accurate and economical, long-lasting metering pump. A wide selection of valve and O-Ring elastomers produce chemical resistance pumps capable of handling both corrosive and non-corrosive fluids.

Bellows Dosing Pumps GRI’s Bellows Dosing Pumps are ideal for low flow, low-pressure metering applications where a fixed flow rate is required. These positive displacement pumps are constructed entirely of plastic and use GRI’s time-proven bellows technology to provide a durable and accurate chemically resistant metering pump. When pumping water in laboratory test conditions, pumps rate at +/- 1%, stroke to stroke.
Piston Diaphragm Pumps Product Overview Piston diaphragm pumps are positive displacement pumps designed to economically transfer small volumes of fluid at low discharge pressures. The lightweight, compact pumps are self-priming, corrosion resistant, and can handle viscous fluids. These features make the pumps ideal for high volume copy machines, scientific and laboratory instruments and other chemical dispensing applications. Standard models are constructed with 12 or 24 volt DC solenoids. A switch is required to supply pulsed voltage to the pump. The energized solenoid pulls the piston and diaphragm up, drawing fluid into the pump. A spring forces the piston back to its original position when the solenoid is de-energized, forcing fluid out of the pump, and the cycle is repeated. Valves are utilized to prevent backflow into the pump and to maintain prime.
