Discharge Pipeline - Recommendations - KSB MEGAFLOW 50-160 Operating Instructions Manual

12.6 Discharge Pipeline - recommendations

To install the discharge pipeline follow these instructions:
a) if the overpressures originated in liquid returning on long lines exceed the limits specified for the line and the pump,
water hammer control devices should be installed on the discharge pipe line.
b) When the diameters of the pump and pipeline flanges are different, the connection should be done through a concentric
reduction.
c) On the points where it is necessary to bleed the air in the pipeline, vent valves should be installed.
d) Install a valve, if possible immediately after the discharge nozzle of the pump, so as to control adequately the flow rate
and pressure or prevent driver overloads.
e) When a non-return valve is installed, it should be mounted between the pump and the valve, prevailing this condition
over item d.
f) Tie band mounting joints should be installed to absorb the system reaction forces, originated on the applied loads.
g) Safety valves, pressure relief devices and other operational valves not included up to now, should be installed as
necessary for adequate operation of the pipeline.
h) The recommendations for the suction pipe line described on items a, b, f, g, i, l and m are also valid for the discharge
pipe line.
