4. Installation notes

4.1 Preparations

1. Unpack pump and check for damage
2. Take packing materials for recycling
3. Remove cover plug/screw cap from intake
and outlet openings
4. Check intake and outlet openings for foreign objects
or packaging materials and remove if necessary.

4.2 Mounting arrangement

The pump can be installed in any position.
To protect the suction side of the pump from damage,
use a coarse filter (mesh size approx. 0.5 - 1 mm).
Where suction heights are > 1 m, use a foot valve at the
end of the suction line – possibly as a unit with the filter.

4.3 System specification

4.3.1

Pressure side

Every line system has a characteristic system curve that
indicates pressure loss relative to delivery flow rate. The
curve and thus the delivery flow rate are influenced by:
• Delivery height
• Line length and diameter
• Properties such as mounted accessories
i
Important!
Pump output data must match the curve.
Outlet
If the system requires more pressure than the pump
can produce, the pump runs in bypass mode with
significantly reduced delivery output.
In this case reduce the system pressure loss by using:
• shorter lines,
• lines with a larger diameter
• accessories with lower pressure loss
(fewer bends, fittings, constrictions)
4.3.2

Suction side

Keep to the following rules with respect
to the suction line:
• keep intake lines as short as possible
• avoid unnecessary bends or constrictions
• ensure line diameter is equal to or larger than
the specified minimum
• do not use too fine a suction filter
Important!
Vacuums > 0.5 bar cause cavitation and damage the
pump (symptoms – operation becomes noisy and
output falls). To avoid height differences between
pump and fill level of the tank to be emptied, keep to:
• m ax. 2 m without foot valve or with air
in the intake line
• max. 2.5 m with foot valve
This pump should not be installed where there are
larger differences in height.
