CONVERTIBLE WELL PUMP INSTALLATIONS
Preparing the Convertible Jet Pump for Deep Well Application,
i.e. 26-75', 4" diameter wells. (Figure 4)
1. Install the pressure regulator control valve along
with pressure gauge, and other fittings (see fig. 4).
Mount on pump's discharge port.
2. Prepare the ejector.
3. Note the nozzle is installed at the factory in the
ejector body (see fig A, page 6).
4. Select and install the venturi tube marked with a
DW. DW denotes deep well. Install as described
above. (see fig.A, page 6)
5. Install a short pipe and foot valve to the intake
end of the ejector to ensure the pipes do not lose
water and remain primed when the jet pump's
motor is off.
6. Using the proper pipe for each port in the ejector,
install pipe on the ejector (Figure 4) and
begin lowering it into the water source to the
depth you have determined will optimize your
pump's water performance.
7. Note the pipes will be two different sizes to
optimize the jet pump's performance. One pipe
will be 1" and the other will be 1-1/4" in diameter.
8. Attach the opposite ends of the pipes to the intake
ports of the jet pump (see Figure4).
9. Install a sanitary well seal and connect the
ejector piping to the pump. Use steel nipples
through the well seal with flexible poly pipe to
avoid crushing the plastic pipe when tightening
the seal.
10. 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 well
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 or
a PTFE-based pipe joint compound. Joints must
be air and water-tight. If the suction pipe can suck
air, the pump cannot pull water from the well.
11. You are now ready to prime the pump per
instructions on page 10.
12. See instructions on page 8 for connecting
discharge pipe to tank.
