Gorman-Rupp Industries
Not Just Pumps, Pumping Solutions
Global Supplier of OEM Pumps
Since 1953 Gorman-Rupp Industries has provided OEM pumping solutions to a vast variety of markets worldwide including the OEM medical device market. GRI's custom designed OEM pumps provide superior chemical resistance, accuracy, and contamination-free designs for the medical device OEM. The company's OEM pumps have made an impact in medical devices for decades with their portfolio of OEM pumps which include magnetic drive pumps, bellows pumps, centrifugal pumps, metering pumps, gear pumps, chemical resistance pumps, oscillating pumps, piston diaphragm pumps, peristaltic pumps and their new line of integrated magnetic drive recirculation pumps.
GRI is not an "off-the-shelf" pump company where one size fits all. GRI takes special care and attention in designing a pump to meet the necessary requirements of the OEM. Known for its innovative designs and fluid pumping solutions, GRI will travel the globe to create an OEM pumping solution that is unique to each of their customers.
Integrity Series: Integrated Magnetic Drive Recirculation Pumps
The Integrity Series is GRI's new line of OEM integrated magnetic drive recirculation pumps. Designed for the recirculation and transfer of fluids, GRI's new integrated magnetic drive recirculation pumps bring a uniquely engineered design to GRI's portfolio of custom OEM pumps. GRI's new Integrity Series integrates the pump's components into a compact, lightweight design, eliminating motor bearings and leaving the impeller assembly as the only moving part. Fewer parts promote longer life, quieter operation, and lower power consumption. The integrated magnetic drive recirculation pumps provide an OEM fluid pumping solution in applications that require a circulation pump or recirculation pump for fluids in medical devices such as cooling systems, chillers, surgical lasers, cosmetic lasers, laser cooling, ultrasonic cleaning, thermal therapy, blood warmers, sterilizers, and circulation baths.
Bellows Metering Pumps
GRI's bellows pumps utilize GRI's proven bellows and valving technology to provide an accurate and economical metering pump with long life. The proprietary blended polypropylene materials of construction and a wide selection of valve and O-ring elastomers produce chemical resistant pumps capable of handling a wide range of fluids.
GRI's Bellows 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 or a lever pivot crank mechanism (Standard Bellows models). 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. Multiple bellows modules can be operated by a single motor for proportioning multiple fluid mediums. The flow rate of each module is independently adjustable.
GRI's Bellows Pumps were specifically designed for metering applications requiring low discharge pressures. Bellows pumps have been successfully applied in OEM medical devices such as, photo, X-ray and dental film processors, silver recovery systems, scientific and analytical instruments, wafer and silicon chip washers and processors, detergent dispensers, blood analyzing equipment, thermotherapy equipment, waste removal systems, and wastewater and water treatment systems.
Bellows pumps are OEM customizable and are offered in many different sizes, configurations, and options to meet the required specifications of a medical OEM device. Also offered is GRI's bleach pump, the Bleach Compatible Bellows Pump, for medical device applications requiring an OEM pump for the purpose of pumping bleach.
Magnetic Drive Pumps
Magnetic drive pumps operate similarly to a standard centrifugal pump except that the motor shaft seal is eliminated. Magnetic drive pumps are designed to isolate the wet end from the motor by a plastic housing which separates the pump head from the motor assembly. Motor torque is transmitted by magnets, attached to the motor shaft, through the housing, to an impeller assembly, which is also attached to a magnet. As the motor rotates the shaft, it magnetically turns the impeller. Leaks caused by shaft seal failure are eliminated. The end result is a more efficient seal-less centrifugal pump that will not leak and is capable of achieving up to 50 thousand hours of continuous duty operation.
GRI uses ceramic shafts with either Teflon® or ceramic thrust bearings as standard materials for each magnetic drive pump line. These robust features add tremendously to the chemical compatibility and overall life of the pump to make it virtually maintenance free.
Magnetic drive pumps are routinely used in medical applications such as cooling systems, chillers, surgical lasers, cosmetic lasers, laser cooling, ultrasonic cleaning, thermal therapy, blood warmers, sterilizers, circulation baths, film processors, x-ray cooling systems, thermal therapy, scientific, laboratory and silver recovery equipment.
