LAWN SPRINKLING APPLICATION
This pump is designed for lawn sprinkling. It is
de signed to deliver plenty of water at full sprinkler pres-
sure. It can pump from a pond, cistern or well points.
Pump discharge can be divided to supply two (2) or
more sprinkler systems. A suggested multiple dis-
charge to service is shown in Figure 3.
Do not use in a pressure tank or booster pump
application.
Pump/Piping Installation
PUMP INSTALLATION
NOTICE: Use only PTFE pipe thread sealant tape
for making all threaded connections to the pump
itself. Do not use pipe joint compounds on plastic
pumps: they can react with the plastic in the pump
components. Make sure that all pipe joints in the
suction pipe are air tight as well as water tight. If the
suction pipe can suck air, the pump will not be able to
pull water from the well.
1. Bolt pump to solid, level foundation.
2. Support all piping connected to the pump.
3. Wrap 1-1/2 to two layers of PTFE pipe thread
sealant tape clockwise (as you face end of pipe) on
all male threads being attached to pump.
4. Tighten joints hand tight plus 1-1/2 turns. Do not
overtighten.
