9-1 Installation Place
If possible, install the pump lower than the minimum level of the tank.
Take sufficient space around the pump to facilitate maintenance or repair and also the motor and
wiring should be connected safely in consideration of flooding.
The pump should be installed at the place where is flat surface and not affected by vibration of
other equipments.
Pump should be installed on the concrete foundation or on the pedestal can be sufficiently
supported. Also, check the level with a leveling instrument so that pump can be installed
horizontally.
9-2 Piping (Universal Precautions)
Decide the piping system which can sufficiently satisfy suction & discharge condition.
Piping should be short and less bending as far as possible and be careful not to make the cavity
at which air stay.
Install piping support lest piping load fall on the pump. Especially, in case of liquid end material of
PVC, be careful about handling.
Flexible joints are recommended to use to pump Liquid End Part.
