PREOPERATION CHECKS
Read and understand the instructions and recommendations contained in this manual.
Disconnect the coupling between the driver and pump.
Test the rotation of the driver to make sure it will operate the pump in the desired direction of rotation. Rotation is
shown on the pump faceplate if the pump has an integral relief valve. When an integral relief valve is used, make
sure it is positioned and adjusted as discussed in Section 5, DIRECTION OF ROTATION AND RELIEF VALVES.
After the unit is mounted and the piping is connected, the pump should be checked to be sure it operates freely
without binding. After operation is proved satisfactory, both pump and driver should be tightly secured and the
alignment rechecked before operation.
Before starting, make sure all guards are in place and the inlet and discharge valves are opened.
After starting the unit, check to see that the pump is delivering liquid. If not, stop the driver immediately and correct
the problem. After the pump is delivering liquid, check the unit for excessive vibration, localized heating, and
excessive shaft seal leakage. Check the pressure or vacuum by installing gauges at both the inlet and discharge
sides of the pump to make sure the pressure or vacuum conforms to specifications.
