Storage
If the equipment is to be stored prior to installation, place it in a clean location. The pump
should be stored in an ambient temperature of 15°C (59°F) to 25°C (77°F) and relative humidity
below 65%. It should not be exposed to any heat source e.g. radiator, sun as this could result in
a negative way on the tightness of the pump. Do not remove the protective covers from the
pump.
When in storage, turn the shaft by hand at least twice per month. The pump-motor unit should
always be stored indoor in dry, vibration and dust free conditions. If the pump is to be stored
more than 1 month, remove the hose form the pump. If this is not possible, run the pump 10
min per week.
Spare hoses must be stored in the same conditions as the pump. What is more, they should be
protected from direct sunlight. Rubber materials are subject to aging and their performance
and lifetime decrease with time.
NOTE!
Do not remove protective covers from the hose when in storage.
1.5.
Foundation
The pump-motor unit must stand on and be fixed to a sufficiently rigid structure that can
support the entire perimeter on which the unit stands. The foundation on a firm bottom is the
most satisfactory. Once the pump is in position, adjust level with metal shims between the feet
and the surface on which it stands. Check that the feet of the pump motor unit stand well on
each of them. The surface on which the foundation stands must be flat and horizontal. If the
unit is fitted on a steel structure, make sure that it is supported so that the feet do not warp. In
any case, it is advisable to fit some anti-vibration rubber pieces between the pump and the
brickwork.
1.6.
Environment
➢
There should be enough space in the vicinity of the pump in order to operate, maintain
and repair it.
➢
The area in which the pump is operated, must be sufficiently ventilated. Excessive
temperature, humidity or dirt may affect the pump operation.
➢
Behind the cooling fan of the motor there must be sufficient room for the hot air to escape
the motor.
1.7.
Suction and discharge piping
A pump is generally part of a piping system that can include a number of components such as
valves, fittings, filters, expansion joints, instruments, etc. The way the piping is arranged and the
positioning of the components has a great influence on the operation and the lifetime of the
pump. The pump cannot be used as a support for the components connected to it.
The flow of liquid from the pump must be as even as possible. It is advisable to avoid any tight
bends or drastic reductions of diameters that may cause flow resistance in the installation. In
case of diameter reduction, it is advisable to use appropriate conical reductions (possibly
eccentric on suction side and concentric on discharge side) at changes of diameter and at a
minimum distance from pump connections of five diameters.
