Installation
1. LOCATION OF UNIT
GHS should be place as near the liquid source as practical so that a short direct suction
pipe may be used. GHS should be accessible for inspection and repair work and
headroom be provided for crane. hoist or tackle if the pump is heavy.
2. PIPING
Both the suction and discharge lines should be independently supported near the pump so that
no strain will be placed on the casing.
3. Suction Piping
The suction line should be as short and straight as possible and contain a minimum number of
bends. Any bends necessary should have large radii. Generally the suction pipe is made one or
two sizes larger than the pump suction branch. For pumps operating with suction lift no valves
other than a foot-valve should be placed in the suction line.
4. Foot Valve
Should have a fee area of at least one and a half times the area of the suction pipe.
An efficient strainer should be provided to prevent foreign matter from being drawn into the
pump or choking the foot valve.When there is any refuse such as sticks, twigs, leaves, etc., in the water, a larger outside screen, or a large basket strainer. This screen should have sufficient openings to keep the flow through it below 0.6m (2 feet) per second.
5. Discharge Piping
The discharge line should be short and direct with the least number of bends and fittings, thus
minimizing the head lost by friction. A non-return valve and discharge valve are usually placed
in the discharge line.
6. Foundation
The foundation should be substantial to reduce vibrations and rigid enough to avoid any
twisting or misalignment.
7. Alignment
GHS driver, if supplied, is correctly aligned on its base plate at the factory. A certain
amount of deformation of the base plate is possible during transit and it is therefore essential
to check alignment before going into operation.
8. Grouting
A space of approximately 25mm (1’’) should be left between the base plate and top of the
foundation to be filled with grouting.
