2 Installation of the pump
2.1 Handling and storage
Refer to the pump weight in the Spare Parts List page 73 before
selecting and using any lifting gear. Ensure that lifting equipment is
correctly rated and used within the specified limits.
The drawings on the left shows how the pump should be lifted.
DW1 - DW2 bareshaft pump: To be lifted manually with the hands.
Alternally eyebolts can be fitted and the pump lifted as DW3 - DW7.
(see fig. A)
DW3 - DW7 bareshaft pump: To be lifted with chain as shown in fig.
A.
DW1 - DW5 pump on baseplate type 1: To be lifted by putting straps
below the baseplate as shown in fig. B.
Fig. C: DW1 - DW6 pump on baseplate type 2: To be lifted by putting
straps below the baseplate as shown in fig. C.
Fig. D: DW6 - DW7 pump on baseplate type 3: To be lifted by putting
straps below the baseplate as shown in fig. D.
After receipt and inspection, if the pump is not to be installed immedia-
tely, the pump must be repacked and placed in suitable roofed storage.
The storage location must be clean, dry and free from vibration.
Plastic or gasket type port covers must be left in place.
If a moist or dusty atmosphere is used for storage, further protect the
pump and unit with a suitable cover.
2.2 Positioning of the pump
Install the pump as close to the liquid source as possible.
Keep the number of bends, tees, valves and other components in the
pipe system leading to the inlet of the pump to an absolute minimum.
Install the pump as low in relation to the liquid source as possible.
Install the pump with sufficient space for maintenance access.
2.3 The pipe system
Ensure that pipe unions are properly aligned and assembled.
Use appropriate gaskets.
Support the suction and discharge piping as close to the pump as
possible.
2.4 Pump rotation
Depending on the required flow direction and the position of the
shaft, the rotation direction of the pump is shown on fig. E, F, G and
H. The rotation direction can be determined by looking at the motor
coupling.
2.5 Power supply
Connect the motor to the mains via a motor switchbox in accordance
with local regulations. Connect the motor in accordance with the
instructions inside the cover of the terminal box of the motor.
Ensure correct pump rotational direction.
