Installation 11
INSTALLATION FOR SURFACE WATER
OR CISTERN (FIGURE 1)
1. The pump should be installed as close to the water
as possible, with the fewest possible fittings (espe-
cially elbows) in the suction pipe. The suction pipe
should be at least as large as the suction port on the
pump.
2. Assemble a foot valve and suction pipe (see Figure 1).
Make sure that the foot valve works freely. Use PTFE
pipe thread sealant tape on threaded pipe joints.
Protect the foot valve assembly from fish, trash, etc,
by installing a screen around it (see Figure 1).
3. Lower the pipe into the water until the strainer is five
feet above the bottom. It should also be at least
1-1/2 feet (.5m) below the water level in order to
prevent the pump from sucking air.
4. Install a priming tee, priming plug, and suction pipe
on the pump (see Figure 1). Support the pipe so that
there are no dips or sags in the pipe, so it doesn’t
strain the pump body, and so that it slopes slightly
upward from the water source to the pump (high
spots can cause air pockets which can air lock the
pump). Seal the suction pipe joints with PTFE pipe
thread sealant tape. Joints must be air-tight and
water-tight. If the suction pipe can suck air, the
pump cannot lift water from the water source.
You have just completed the suction pipe plumbing for
your new peripheral vane pump. See next column for
discharge pipe connections.
