4 INSTALLATION
Equipment operated in hazardous locations
must comply with the relevant explosion protection
regulations. See section 1.6.4,
Products used in
potentially explosive atmospheres.
4.1 Location
The pump should be located to allow room for
access, ventilation, maintenance and inspection with
ample headroom for lifting and should be as close as
practicable to the supply of liquid to be pumped.
Refer to the general arrangement drawing for the
pump set.
4.2 Part assemblies
Motors may be supplied loose on LRV pumps,
typically on frame sizes 250 and above. It is the
responsibility of the installer to ensure that the motor
is assembled to the pump and lined up as detailed in
section 4.5.2.
4.3 Foundation
There are many methods of installing
pump units to their foundations. The correct method
depends on the size of the pump unit, its location and
noise vibration limitations. Non-compliance with the
provision of correct foundation and installation may
lead to failure of the pump and, as such, would be
outside the terms of the warranty.
