1. INSTALLATION
1.1. Operation principle
In order to operate the pump, the liquid level has to be above the impeller before start-up
(for details see chapter 1.9
Example of installation ). The rotating impeller generates a
centrifugal force accelerating the liquid through the pump casing and into the discharge
piping.
It works by means of a “liquid seal” meaning the liquid level can drop below the
impeller line once the pump is operating. When the liquid inside a sump reaches the pump
inlet or end of a suction pipe, the liquid column is broken and the level must be increase
above the impeller once again in order to restart the pump.
1.2. Receiving inspection
Although precaution is taken by us when packing and shipping, we urge you to carefully
check the shipment on receipt. Make sure that all parts and accessories listed on the packing
list are accounted for. Immediately report any damage or shortage to the transport company
and to us.
1.3. Storage
If the equipment is to be stored prior to installation, place it in a clean location. Store the
pump on the motor fan cover in an upright position. Clean the pump thoroughly before
installation. When in storage, turn the shaft by hand at least twice per week
1.4. Lifting and transportation
Before handling the pump check the weight of the pump (see 6. Data ). Refer to Your local
standards on how to handle the pump. If the weight is excessive to transport by hand it must
be lifted using slings and a suitable lifting device e.g. a crane or forklift.
Always use at least two slings and make sure they are secured in such a way to prevent the
pump from slipping and that the pump unit is hanging straight.
Never lift the pump with only one sling. Incorrect lifting can cause serious injury and/or
damage to the pump.
Never lift the pump under pressure.
