Permanent, Vertical Or Horizontal, Dry Installation; Temporary, Vertical, Submerged Installation In A Pit - Grundfos SE Serie Instrucciones De Instalación Y Operación

6.4 Permanent, vertical or horizontal, dry installation

Use isolating valves on either side of the pump to facilitate
service on it.
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
cable is not sharply bent or pinched.
7. Connect the power- and the control cables, if any.
Fasten the pump to the inlet and outlet pipes by flange connections.

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.

6.5 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 port 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 casing.
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
cable is not sharply bent or pinched.
6. Connect the power- and control cables, if any.
