Installation
Suction height
- suction pipe should
have a slope of 0.39" per 3.3 ft of
suction. Never exceed 16.4 ft suction,
considering friction.
(Figure 3)
Positive/Drowned Suction
- A gate
valve is installed in the suction pipe
to service the pump
(Figure 4)
. Volute
or body have plugs, and these must
be removed to allow trapped air to
escape.
Use pipe or hose reinforced
sufficiently
robust
to
prevent
destruction due to high pressure.
Discharge pipe
Due to the cost of energy or BHP
necessary to overcome the friction
generated by using a smaller
diameter pipe, a larger diameter
discharge pipe is commonly used
than the required by the volute or
body.
