Installation
• The pump shall be installed in a dry place, away from the
elements; with air flow to allow air flow for the adequate
ventilation (
A
)
Ambient temperature not exceeding 104º F
• Use bolts to fix the pump onto a concrete base to
prevent vibrations ( B ) The pump shall be installed in a
horizontal position to assure it runs properly.
• The suction lines and pressure pipes shall be supported
to the wall or the floor to prevent transmission of tension
to the pump body ( C )
• Use care not to damage the pump and / or the pipes due
to excessive tightening of the joints.
Mounting
• The suction pipes diameter shall not be smaller than the
diameter of the pump water inlet. If the suction height
exceeds 13 ft, use a pipe with a larger diameter.
• The suction pipe shall be completely watertight, the end
shall be submerged into water at least one meter and a
half, where using a (
D
). The pipe shall be set totally
vertical and bend to 90º towards the water inlet in the
pump.
• Failure to follow these indications will
result in air sealing – in and bubbles interfering with the
pump performance.
Suction line (inlet)
• The outlet pipe will need a gate valve (
E
) to adjust the
required flow speed and pressure.
• It is recommended to set a check valve (
F
) between the
pressurized water from the pump and the gate valve to
prevent the unexpected return of water columns exceeding
65 ft
