C.R.I. peripheral pumps volute chamber and impellers are designed to give the best possible hydraulic efficiency and suction lift characteristics. Sealing is by means of a bellows mechanical seal made of carbon and ceramic is fitted over the shaft, which is ground to close tolerances. Self priming models have built in check valve on the suction side which requires no foot valve. The brass inserts provided inside the pump casing educes wear & tear and this give longer life and prevent the pump from seizing if it is kept idle for long period. Pumps are powered by a totally enclosed fan cooled, A.C. induction two pole motors suitable for continuous duty. Motor stator is made of low watt loss steel laminations. The windings are of high grade enameled copper wire and are varnish impregnated. Dynamically balanced rotor ensures vibration and noise free operations. Construction of motor frames and usage of quality materials result in high performance and low temperature rise thereby increasing the life cycle of the motor. A thermal over load protector (motor protector) is incorporated in all single phase motors. These pumps require an adequate motor protection control panel.

Increased Capability for Reduced Volumes
Standard ANSI pumps (with expanding style volute casing) are not designed for low flow, high head applications. Throttling or recirculating flow to attain low flow conditions causes excessive radial load and shaft deflection—all of which can result in premature failure of bearings and mechanical seals. Griswold’s Model 811LF series features flow capacities as low as 4 GPM, and heads as high as 920'. Plus, 811LF pumps are designed with a circular concentric casing in conjunction with a radial vane impeller to reduce those excessive radial loads and minimize shaft deflection, thus extending MTBPM.
Circular Concentric Volute Casing
The fully machined concentric volute reduces excessive radial loads, shaft vibration and deflection—extending bearing and mechanical seal life. Class 150 raised face flanges are standard with the Model 811LF series for positive sealing. Class 300 raised face flanges are available as an option.
Low Flow Radial Impeller
When operating in reduced volume conditions, the Griswold impeller’s radial vanes provide better hydraulic control than traditional ANSI impellers. Balance holes reduce both axial thrust and seal chamber pressure, extending bearing and seal life.

Inside the rotor slots (1), positioned eccentrically in the pump cylindrical housing (2), free moving vanes (4) are inserted (3). When the rotor turns, the centrifugal force throws the vanes against the cylindrical wall creating multiple chambers. The air taken from the inlet port (4) is compressed inside these chambers and is thrown out to the outlet port (5).
