7.1. Installing the pump
1) Decide where the pump is to be installed and secure a site.
Note:
-
The suction lift should be kept as short as possible.
-
Sufficient space around the pump for maintenance must be provided.
When fixing the pump in place, use the cushions on the pump base. The tied-down bolts should be tightened
a little at a time to secure the pump.
SELF PRIMING APPLICATION
Suction lift capability may vary depending on the construction materials and
application parameters. The range is from 5 meters dry to 9 meters in a
primed condition (values calculated for pumping water at 20 degrees
Celsius).
SUBMERGED OPERATION
All pumps may operate in full submersion. Construction materials must be
compatible with surrounding liquid and the air exhaust must be placed above
the liquid level.
POSITIVE SUCTION HEAD
Common as a method of drawing off the bottoms of holding tanks and
clarifiers. Optimum inlet pressure should be kept at 0.2-0.3 bar.
!
CAUTION
When installing accessories prevent any foreign matter from getting into the product.
Otherwise malfunction of the air-valve may follow.
