This quadruple pump station has been overhauled utilizing the existing motors and pumps.  All motors have been rewound for Inverter duty, bearings have been replaced and pumps overhauled completely.    All tolerances in the pumps were checked to factory specifications to insure the highest efficiency.  Impeller buildup work was done to eliminate chips and crevices. The motors were re-installed on the mounting bases.
 

Toshiba Variable Frequency Drives installed to:

1.      Reduce electricity usage.  These motors operate in the 40to 60Hz range.  As such there is approximately a 30-50% reduction in electrical usage.

2.      Control the volume of pumping

3.      Controlling the substation remotely.

4.      Cycle pumps for longevity

5.      Reduce maintenance:

A.     sensing overloads and automatically stopping

B.     Cycling so seals do not dry out
