Page 10: Section Iii: Installation
SITE PREPARATION Flowserve Pump Division MSX Series 2 wet well pumps can be installed in a permanent well via a guide rail system or on a pedestal base so that they are transportable. Series 2 pumps can also be installed in dry pit applications with the use of a suction base and permanent discharge piping. -
Page 11: Grouting
The purpose of grouting is to prevent lateral shifting of the equipment supports and not to take up irregularities in the foundation. Only non-shrinking grout with a 6000 psi (41.4 MPa) compressive strength in 72 hours should be used. Flowserve Pump Division recommends the following procedure for grouting: Build a wooden form around the outside of the base to contain the grout. - Page 12 Figure 1: Guide Rail System Flowserve Pump Division - 12...

Page 17: Insulation Testing
Insulation Testing Flowserve Pump Division recommends that the motor winding insulation be checked once the unit is in place and prior to applying power to the unit. If the insulation resistance of the motor winding and power supply cable is to be tested, use an instrument designed for this purpose (500 VDC). To measure the insulation resistance, use to following procedure: Disconnect all leads of the power supply cable and clean them carefully. -
