2.3 General guidelines for calculation of
pressure losses
The suction conditions can be optimized
according to below guidelines .
2.4 General comments on
Filtration
A good filtration is vital to ensure a long and
trouble free operation of the pump.
When selecting a filter or strainer, please note
that filter materials should be compatible with
water, i .e . should neither corrode or dissolve . Also
be aware of the electrochemical series of the
applied materials .
•
Main filter must have a fineness of 10 µm
abs . β
10
≥ 5,000
•
The pressure loss across the filter should be
monitored
•
Please contact the Danfoss Sales Organiza-
tion for further filter details
Water tank
Must be made of corrosion-proof material such
as stainless steel or plastic and must be sealed to
prevent entrance of impurities from the environ-
ment .
Automatic pressure equalization between tank
and surroundings must be ensured .
Inlet from the water supply (the return line) and
inlet to the pump should be placed in opposite
ends of the tank to calm and deaerate the water,
and to ensure optimum opportunity for particles
to settle .
Pump suction line should be placed above the
tank bottom in order to prevent settled particles
from being led into the pump .
