Graymills HP7.515HC-F 7.5

Graymills coolant pump are typically found on OEM machine tool equipment and are thus well suited for replacement or retrofit machine tool pumping applications. These pumps can also be used on other industrial applications requiring a vertical cast iron or stainless pump.

HP Series pumps are designed for reliable, heavy duty, high flow pumping of industrial solvents, slurries, abrasives, and other fluids. Interchangeability of motors and impellers allows you to specify the combination which best meets your needs.

Pump performance can be varied by specifying a different motor and impeller size. The graph as the right allows you to determine the horsepower/impeller combination which will handle your operating requirements. Curves 1 thru 4 identify the pump performance for each of 4 impeller options (A, B, C, D). Diagonal lines express horsepower (HP). To use the chart, locate your required operating point (intersection GPM & TDH). If the operating point is between two curves, select the higher of the two. The required HP will be shown by the first diagonal line to the right of the operating point.
