4 OPERATION
4.1 Before Starting
Before initial starting of the pump, make the following inspection:
4.1.1 The unit baseplate is grouted and bolted to the foundation.
4.1.2 Alignment between pump and motor.
4.1.3 Motor is correctly wired to starting device, check voltage, phase and frequency on
motor nameplate with line circuit. Ensure correct direction of rotation prior to
coupling to pump. Check by starting motor and switching off immediately. Observe
rotation is the same as the arrow direction on the pump casing.
4.1.4 Bearing lubrication is provided (see lubrication section), also check driver lubrication.
4.1.5 Mechanical seal has been fitted or stuffing box has been packed.
4.1.6 All rotating parts are found to be free when turned by hand.
4.1.7Pump is primed. Never run the unit dry. The liquid in the pump serves as a lubricant
for close running fits within the pump and the pump may be damaged if operated
dry. The pump may be primed by using an ejector, exhauster or vacuum pump. If a
foot valve is used in the suction line, the pump may be primed by venting and filling
the casing with liquid.
4.2 Starting
4.2.1 Close valve in discharge line.
4.2.2 Open fully all valves in the suction line.
4.2.3 Turn on seal water to the stuffing box where external pipe supplied.
4.2.4 Prime the pump.
4.2.5 Start the pump driver.
4.2.6 When the pump is operating at full speed, open the discharge valve slowly.
Do not operate pump for prolonged periods with closed discharge valve, so as to avoid
overheating.
The pump should be shut down at once and the trouble corrected if the pump is running at
its rated speed and found to have any of the following defects:
a) No liquid delivered.
