5. Handling the pump.

The pump must be packaged properly during transport to avoid damage to the pump or its

surroundings. It can be transported and/or stored in vertical or horizontal position.

Always place the pump on a stable surface, so it cannot tip over during service, transport,

testing and installation.

For storage for long periods of time the pump must be serviced and checked again before

use. Before electrical connection the impeller shall be turned by hand to ensure the correct

friction of the mechanical seal.

Accidents in relation to installation can be minimized by taking care. Be especially careful with the pump's

weight and the risk of electrical accidents.

When lifting with hoisting equipment, these must always be of the correct dimensions, with consideration to

the lifted weight.

- Never walk under hanging loads.

- Never lift or tow the pump in the cable.

- Never get entangled in pump cables and lifting chains.

The immersion depth for pumps covered by this manual is max. 20 meters.

The temperature of the pumped media must not continuously exceed +45°C.

Cavitation may occur, if the pump intake becomes obstructed or if the NPSH value is too low,

causing damage to the internal elements of the pump.

Always provide the right suction conditions for the pump.

Wet-Pit installation with submerged pump on DCB.

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.

Mount the DCB (Discharge Connection Bracket) firmly onto the

bottom of the well with expanding bolts.

When mounting the upper guide brackets (UGB), the guide tubes

must be vertical and parallel.

Connect the discharge pipe to the DCB flange. We recommend

mounting a non-return check valve on the discharge pipe.

The hoisting device must be installed directly above the pump's

center of gravity.

The pump will then automatically connect at bottom position on the

DCB, loosen again when lifted. (Cooling jacket is an option)

Always check the discharge pipe dimension is correct according to the required m³/h capacity.
