Page 4: Safety Recommendations
Operation Manual. 2. Safety Recommendations. • Wear safety shoes when handling heavy parts or tools. • Do not operate the pump with the discharge valve closed. • Do not remove drain plugs or valves when the pump is running. • Never attempt to attach pipes to the pumps forcing it. Sizes must be appropriate. -
Page 5: Installation
GS Pumps. 3. Installation. Location. • Place the pump as close to the suction source as possible. Suction piping should be as short and direct as possible. • Place the pump below the water level whenever possible. This will facilitate priming, ensures a constant flow of liquid, and pro- vides a positive suction. • Make sure the NPSH (Net Positive Suction Head) is provided at the suction end of pump considering the location relative to the whole system. -

Operation Manual. Ensure the board. • After the concrete slab has been poured, place the pump base plate over the anchor bolts and lay it on loose fit wedges or shims placed near each anchor bolt and at intervals not to ex- ceed 24”... - Page 7 ATTENTION.

40 to 60 drops per minute leakage. This is required for shaft lubrication. After initial start up, additional packing and adjustment may be required. • All pumps on GS line of WDM Pumps are equipped with me- chanical seals matched to conditions for which the pump was sold. -

• Check incoming power source to ensure that it is the same as the voltage and phase of the motors. Priming. • WDM ME line pumps are not self-priming, and must be com- pletely primed, filled with liquid, before starting. • If the pump will operate with a positive suction head, prime by opening the suction valve allowing liquid to enter pump casing. -
Page 10: Pre-Start Checklist
Consult instruction book for proper operation and maintenance of the pump and its supporting components. Make the following inspections before starting your WDM Pump: • Make sure all wiring connections to the motor (and starting de- vice) match the wiring diagram and produce clockwise rotation as viewed from the back of the motor. -
Page 11: Motor Rotation
GS Pumps. Motor rotation. CAUTION. Never check driver rotation unless pump and driver couplings are disconnected and physically separated. Failure to follow this instruc- tion can result in serious damage to pump and driver if rotation is wrong. After the unit has been wired and checked to insure that all com- ponents in the system (disconnect device, magnetic starters, pilot devices and motors) are properly connected, check motor rotation as follows:... -
Page 12: Starting The Pump
Operation Manual. 4. Starting the pump. • Install coupling guard on flexible coupled units. • Fully open gate valve (if any) in suction line, and close gate valve in discharge line. • Fill suction line with liquid and completely prime pump. • Start the motor (pump). • Immediately make a visual check of pump and suction piping for pressure leaks. -
Page 13: Maintenance
GS Pumps. 5. Maintenance. WARNING. The pump must not be operated without an approved cou- pling guard in place. Failure to observe this warning could result in injury to operating personnel. Before attempting any inspection or repair on the pump, the driver controls must be in the “OFF” position, locked and tagged to prevent injury to personnel performing service on the pump. - Page 14 Operation Manual. One-half to one cubic inch of grease is sufficient for motors 5.0 hp and under, with proportionately more grease for greater HP motors. • Most fractional and some integral frame motors have “sealed- for-life” bearings, and do not require further lubrication through- out motor life. • Always follow motor manufacturer’s lubrication instructions, and periodically check grease fittings and drain plugs for leaks.

After draining oil, replace the fittings and refill with an acceptable oil selected from Table 3. After the first oil change, the oil should be changed again at 2000 hours and then at intervals of 8000 hours or once yearly, thereafter.
