• If a reducer is connected to the inlet, use an eccentric type to
prevent problems due to trapped air. See Figure 6.
• This pump is not self-priming. If the pump is installed above
the supply liquid level, install a foot valve or other system
check valve (Figure 7, item A) to keep the system flooded for
priming.
• A throttling valve may be required to control the pump flow
ra
te to prevent motor overload. Always install a throttling
valve (Figure 7, item B) in the discharge piping and at least
10 diameters from the pump outlet. NEVER install a throttling
valve in the supply piping (Figure 7, item C).
Installations that may
cause operation problems
• Any system throttling valves or similar devices to control flow
rate must be installed in the discharge line. DO NOT install
any system throttling valves or similar devices to control the
flow rate in the supply line. (See Figure 7.) Restriction in the
supply line may cause cavitation a
nd pump damage.
• “Water hammer” in the system
can damage the pump and
other system components. Water hammer often occurs when
valves in the system are suddenly closed, causing lines to
move violently with a loud noise. One way to eliminate water
hammer is to slow down the actuation speed of the valve.
• Do not expose the pump to freezing
temperatures with liquid
in the casing. Frozen liquid in the casing will damage pump.
Drain the casing before exposing it to freezing temperatures.
