GRI’s OEM custom fluid pumps provide superior chemical resistance, accuracy, and contamination-free designs for medical device applications. GRI’s pumps have made an impact in medical devices for decades with our portfolio of OEM pumps, which includes Magnetic Drive Pumps, Bellows Metering Pumps, Centrifugal Pumps, Gear Pumps, Oscillating Pumps and our newest line of Magnetic Drive Recirculation Pumps.

GRI Pumps has been proved in many 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, scientific, laboratory and silver recovery equipment.

Magnetic Drive Pumps

Magnetic Drive Pumps operate similarly to Centrifugal Pumps except that the shaft between the motor and the pump head is eliminated and separated by a plastic housing. The pump impeller is connected to magnets that are driven by magnets on the other side of the housing that are connected to the motor. The benefit of Magnetic Drive pumps over Centrifugals is that leaks created by failure of the shaft seal are eliminated. 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, an important feature when installed in a medical device.

Magnetic Drive Recirculation Pumps: The Integrity Series is GRI’s newest line of magnetic drive 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 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.

Bellows Metering Pumps

GRI’s Bellows Metering 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, thermo therapy 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 application. Also available is the Bleach Compatible Bellows Pump, for applications requiring the pumping of bleach.

Turnkey Solutions

Many times it is more cost effective for GRI to assemble a customer’s final unit with GRI’s technology incorporated. GRI has the engineering capability and manufacturing experience to offer turnkey solutions when it fiscally benefits the customer.
