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.

Specifications

Max. Flow Rates: Range to 60 gpm.


Max. Discharge Heads: Range to 85 feet.


Max. System Pressure: Dependent on seal type. Consult GRI.


Max. Fluid Temperature: To allow for optimum life, pumps with lip seals are limited to 180°F (82°C) and pumps with mechanical seals permit operation to 220°F (104°C).


Motors: All motors are rated for continous duty, thermally protected and UL recognized.

For proper selection of the wetted materials of construction (pump body, impeller, adapter disc, O-ring, impeller bearing) refer to the Chemical Resistance Charts.

The chart below is just a general overview of the Centrifugal Pumps offered. GRI specializes in the custom design and manufacturing of fluid pumps for the OEM market.

There are many variables that must be considered when specifying a Centrifugal Pump for an OEM application. At first glance you may not find a pump that meets your exact requirements. GRI recommends that you contact our Technical Sales Staff to discuss your project so that the right pump can be specified. Many times we will customize an existing pump to meet your needs or design a new pump according to your system’s exact specifications.
