DanPumps S-WP Series, Installation Manual

Page: 7 / 20

Dry-Pit installation with submerged pump on legs.
Cables for the pump must be installed in such a way that they avoid any sharp
bends or getting squeezed. Never let the cables hang in a way that they might get
sucked into the pump.
The pump is delivered with support legs.
The pump must be mounted on a solid surface, and the foundation/base must have
sufficiently strength to support the pump.
The legs are adjustable; the height is regulated by loosening the two bolts on each
leg and tighten them again at the desired height. The pump volute is predrilled for
standard DN flange
Then mount the inlet and discharge pipes. (Suction elbows can be supplied)
We recommend mounting a ball valve on the suction side, and a ball valve + a non-
return check valve on the discharge side.
Check that the pipe dimensions are correct according to the required m³/h capacity.
Contact your local DanPumps A/S dealer, who can advise you.
Portable installation.
When mounting this installation type, it is very important that the cables are
installed in such a way that they do not bend, get damaged by vehicles etc.
It is also important that there is no pulling /towing in the cables or discharge
hose.
The pump must be mounted on a solid surface and in a vertical position, so it
does not tip over or “dig” into the sand, sludge etc.
Please note the pump’s inlet is exposed all physical contact must be avoided.
Keep a minimum safety distance of 5 meters from a pump in operation.
The pump is capable to give a very powerful suction under water. Never
underestimate this.
If necessary, then mount a plate with holes like a strainer, which can be
screwed onto the pump’s frame to avoid large objects being sucked into the
pump.
Discharge info for all 3 installations.
To reduce load and power dissipation, we recommend use of pipes with the same (DN) or larger diameter
than the pump discharge. Connection elements that may cause air pockets should not be used under any
circumstances.
The diameter of the pipes used, ought to be such, which ensures the water speed remains below
2 m/s (7 feet per second).
7. Electrical installation.
Work is only permitted to be carried out by qualified specialists and must to be carried
out in accordance with local regulations. Let a qualified electrician do this job.
Before work commences, ensure that all power is switched off and cannot be switched
on again. Check that supply voltage and frequency are the same as rated data on the
pump.
Motors can be used with a power supply deviation of ± 5% voltage and ± 2% frequency, according to
IEC60034-1
Connections must be made in such a way as to ensure that a permanently safe electrical connection is
maintained, both for the main supply and the earth connection. A ground fault circuit breaker is a must.
The electric board must be equipped with a motor guard that fits the motor size.
This relay must be set as follow for direct or star-delta start:
