Installation
PUMP INSTALLATION
IMPORTANT
: Pump is built to handle
clear water only; it is not designed to
handle water containing sand, silt or
other abrasives.
1. Refer to Figures 6, 7, and 8 for
typical installations.
Support pump and
piping when
assembling and when installed. Failure to
do so may cause piping to break, pump to
fail, motor bearing failures, etc.
2. If the pump is used as part of a
permanent installation, bolt to a rigid
foundation.
Use only
components that are
rated for maximum pressure pump can
produce when used in boosting system or
any other system. Do not exceed the total
maximum pressure boost as listed per
model in Performance Charts B.
PRESSURE BOOST SYSTEMS
1. On pressure boost systems, locate
the pump so that there will always
be a positive supply of water to the
pump (See Figures 6, 7 and 8).
2. For service convenience, install a
gate valve and union in the inlet and
discharge line.
Do not use a globe
valve or other
restricting type of valve that will seriously
restrict the pumps discharge capacity.
3. Install a check valve as shown in
Figure 6. Be sure check valve flow
arrows point in the direction of water
flow.
4. Whenever dirt, sand or debris is
present in the supply water, install a
strainer or filter on the inlet side of
the pump (See Figure 7).
NOTE
: For heavy amounts of sediment,
install a trap filter on the inlet side of the
pump (See Figure 5).
NOTE
: Pressure gauges installed before
and after the filter will show pressure
differential indicating the need for filter
replacement or cleaning.
