4.0 Installation
The pump can be mounted in one of two ways:
•
Flooded Suction (Figure 1) [ideal installation]; or
•
Suction Lift (Figure 2)
Suction conditions can affect the performance of the pump. Consult your distributor for
additional information.
Your metering pump must be mounted so that the suction and discharge valves are vertical.
When pumping downhill or into a low or no pressure system, a backpressure / anti-syphon
device should be installed to prevent over pumping or syphoning.
