The unit v/pump has to be fixed on a rigid structure that will enable the support of the
entire structure. Make sure that the pump is fixed on a plane surface. You can use shims
under the base-plates of the motor. If necessary use “bumpers” to reduce vibrations
towards the fixing surface.
2.4 Installation
Ekin Endüstriyel is not responsible for injury to people or damage to things caused by
the wrong installation of the pump or installation executed by non-qualified personnel.
Install the pump in a position that guarantees a simple use.
2.5 Hydraulic System
The pump is generally part of a hydraulic system that can include a various number of components
such as, valves, fittings, filters, expansion joints, instruments, etc. The way the piping is arranged
and the position of the components has a great influence on the operation and on the life of the
pump.
2.6 Pipes Connection
2
Locate the pump as near as possible to the liquid source and under the level of the liquid (under
head). Always use pipes as short and straight as possible and limit the number of bends assuring
radius of curvature as large as possible. Avoid air siphon that can be created in the long piping
line. Avoid the creation of siphon also before the suction of the pump.
It is better to rinse the internal pipes of new plants before installing the pump in order to
remove possible debris which can enter the pump and damage it.
The piping should be properly supported and kept in line independently from the pump,
until its connections, so that the piping doesn’t exert loads on the pump.
The sizes of the suction and discharge pipes have to be at least as large as the inlet
connection of the pump. Diameter restriction of the suction pipe is responsible and
cause of the cavitation of the pump, creating a loss in the performance of the pump and
a rapid wear. It’s advisable always to use (if in case) flexible reinforced pipes that don’t
collapse under a situation of depression.
The suction line has to be clean and/or contain a filter to protect the impeller from
damage due to impurities, or other foreign particles, especially when starting the plant
for the first time. Don’t use metallic piping with plastic pumps.
Don’t use tools to connect piping to plastic pumps. Make sure that the connections are properly
tightened otherwise the suction capacity will be reduced.
