PUMP INSTALLATION

4.1 INSTALLATION INTO PIPELINES

The arrows on the hydraulic casing and thermal insulation indicate the direction
of the medium flow. For the pump to operate with minimal vibrations and noise it
should be installed into pipelines with its 1-1 axis in a horizontal position. Pipes
should be without curves for at least 5-10 D (D = rated pipe diameter) from the
first curve.
Desired head orientation can be achieved by rotating the pump head (allowed
positions shown in figure 1. Pump head is mounted on the hydraulic casting
with four screws. The pump head can be turned by unscrewing the four screws
(figure 3). When reassembling care should be taken to ensure the seal fit.
Failing to ensure seal fit could cause leaking of water into and damage to
internal pump parts.
Pump ambient should be dry and well lit. The pump is sealed from dust and
water according to its IP class.
• Misconnection or overload could cause pump shutdown or even
permanent damage.
• The pump doesn't have a ventilation screw. It is ventilated
together with the system. Air in the pump can cause noise, which
will disappear after a short working period.
