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 typi-
cal 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 per-
manent installation, bolt to a rigid
foundation.
!
Use only compo-
nents that are rated for maximum pres-
sure 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 sedi-
ment, 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 clean-
ing.
