8.2.3 FASTENING DOWN
Bolt the pump on to a concrete base or suitable metal structure.
Use of anti-vibration supports is highly recommended in com-
mercial buildings (with occupants) if the concrete base is an in-
tegral part of the reinforced concrete structure of buildings.
When fastening, use a drill bit to center mark the 4 holes in the
base of the pump on the surface it is due to be installed on.
Use a drill to make 4 holes (dia. 12mm (15/32") for EVMSU 1, 3,
5, 10, 15, 20 pumps and dia. 14mm (9/16") for EVMU 32, 45, 64
pumps). Move the pump back into position, line it up with the
pipes and tighten the screws all the way.
The position of the fastening holes is also illustrated in section 15.6.
8.2.4 PIPEWORK
In addition to the instructions given below, also comply with the
general instructions found in sect. 15.7 of the manual and with
the directions in fig. 1.
Suction and discharge piping must be sized to
withstand the maximum working pressure of the
pump.
WARNING!
It is recommended that a pressure gauge be installed on the
discharge line before the check valve and isolating valve. Use
adequate supports for the suction and discharge lines to avoid
stress on the pump flange. If the pump is installed with a suc-
tion lift arrangement (liquid level lower than the pump) and it
feeds an open circuit, install a foot valve at the end of the suc-
tion line and use a hose connected to the pump.
Ensure that available NPSH is greater than NPSH
required by the pump. Insufficient NPSH will
result in cavitation, which reduces pump
performance and may result in damage to the
pump. Refer to the pump curves.
8.2.5 ELECTRICAL CONNECTION
Electrical connections must be made by qualified
personnel. Motor and circuit protection must be
appropriately sized. Observe all applicable codes
and standards.
Connect the electrical supply to the pump, following the motor
manufacturer’s instructions.
