Dry, horizontal installation on horizontal base stand
Pumps in dry installation are installed permanently in
a pump room.
The pump motor is enclosed and watertight.
Proceed as follows:
1. Mark and drill mounting holes in the concrete floor
or foundation.
2. Fit the bracket or base stand to the pump.
3. Fasten the pump with expansion bolts.
4. Check that the pump is vertical or horizontal.
5. Fit the inlet and outlet pipes and isolating valves, if
used, and ensure that the pump is not stressed by
the pipes.
6. Adjust the length of the power cable by coiling it
up on a relief fitting to ensure that the cable is not
damaged during operation. Fasten the relief fitting
to a suitable hook. Make sure that the cables are
not sharply bent or pinched.
7. Connect the power- and the control cables, if any.
Fasten the pump to the inlet and outlet pipes with
flange connections.

- - 5.0
The pull-out strengths stated are without
safety factor. The required safety factor
may depend on the materials and method
used for anchoring.
In horizontal installations, use a reducer
between the inlet pipe and the pump. The
reducer must be eccentric and has to be
installed the way its straight edge is
pointing upwards. Therefore the
accumulation of air in the inlet pipe and the
risk of operation disturbance are
eliminated.

4.5 Temporary, vertical, submerged
installation in a pit
Use the chain to move the pump.
Proceed as follows:
1. Fit the ring stand to the pump inlet flange.
2. Fit a 90 ° elbow to the pump outlet and connect
the outlet pipe or hose. If a hose is used, make
sure that the hose does not buckle and the inside
diameter matches the outlet diameter.
3. Lower the pump into the liquid by a chain secured
to the lifting bracket of the pump. Place the pump
on a level, solid foundation.
4. When the pump is placed firmly on the bottom of
the pit, attach the end of the chain to a suitable
hook at the top of the pit, so the chain cannot
come into contact with the pump housing.
5. Adjust the length of the power cable by coiling it
up on a relief fitting to ensure that the cable is not
damaged during operation. Fasten the relief fitting
to a suitable hook. Make sure that the cables are
not sharply bent or pinched.
6. Connect the power and control cables, if any.
4.6
Level of pumped liquid
Do not let the pump run dry.
Install an additional level switch to ensure
that the pump is stopped in case the stop
level switch is not working.
The level of the pumped liquid must be
controlled by level switches connected to
the motor control circuit.
