Pumps

nnnn

Magnetic drive centrifugal pump operation is similar to a standard centrifugal pump except

nnnn

the motor shaft seal is eliminated. Instead, magnetic drive pumps are designed to isolate ^^^^^Hl

nnnn

the wet end of the hydraulic circuit from the motor by driving an impeller and magnet as-

nnnn

sembly with a radial or axial drive magnet assembly attached to the motor shaft. Motor torque is transmitted by the drive

nnnn

magnet through a plastic housing that separates the driven impeller magnet from the fluid being pumped. Leaks caused by

nnnn

shaft seal failure are eliminated. The end result is a more efficient seal-less centrifugal pump that will not leak and is capable

nnnn

of achieving up to 50 thousand hours of continuous duty operation.

nnnn

The impeller shaft and bearing system features an excellent combination of inert materials of construction to handle the

nnnn

most aggressive of chemicals and cooling passages designed to use the pumped liquid as a lubricating coolant. GRI uses

nnnn

ceramic shafts with either Teflon® or ceramic thrust bearings as standard materials for each magnetic drive pump line.

nnnn

These robust features add tremendously to the chemical compatibility and overall life of the pump to make it virtually main-

nnnn

tenance free.

nnnn

Impellers and pump bodies are designed to produce efficient flow and head characteristics required in today's applications.

nnnn

The hydraulic designs, coupled with motors specifically designed for the pump end, means less power consumption for the

nnnn

work performed.

nnnn

Typical OEM applications include film processors, Laser and x-ray cooling systems, medical, scientific, laboratory and

nnnn

silver recovery equipment. Magnetic drive centrifugal pumps must be used where flooded suction conditions exist.

nnnn

AC or DC motors.

nnnn

Materials in Contact with Solution: Please see GRI website for individual pump series.

nnnn

Selection Procedure: Determine the flow and discharge head requirements for your system. Go to our website to view the

nnnn

flow rate curves for each magnetic drive pump series. The performance curve characteristics of a pump model may not meet

nnnn

the exact requirements of your application. It may be necessary to throttle the discharge of a pump with more flow or head

nnnn

capacity to fine tune the performance.

nnnn

For proper selection of the wetted materials of construction (pump body, impeller, adapter disc, O-ring, impeller bearing)

nnnn

please visit GRI's website to view Chemical Resistance Charts.
