Arrows on the pump base show the direction of fl ow of
liquid through the pump
Page 21 shows:
-Dimension of the base
-Pipework connection
-Diameter and position of foundation bolts
The pump can be installed vertically or horizontally.
Ensure that an adequate supply of cool air reaches the
motor cooling fan. However, the motor must never fall
below the horizontal plane.
To minimize possible noise from the pump, it is advisable
to fi t expansion joints either side of the pump and antivi-
bration mountings between foundation and pump.
Isolating valves should be fi tted either side of the pump
to avoid draining the system if the pump needs to be
cleaned, repaired or replaced. The pump must always
be protected against backfl ow by means of a non-return
valve (foot valve)
Install the pipes so that air locks are avoided, especially
on the suction side of the pump.
In the case of installation in which:
-The discharge pipe slopes downwards away from the
pump.
-There is a risk of siphon effect
-Protection against backfl ow of unclean liquids is neces-
sary.
A vacuum valve must be fi tted close to the pump.
The pump is available to install outside, but there is suita-
ble protection.
