Operating Instructions and Parts Manual
Plunger Pumps
Winter or Long Time Storage
1. Drain all of the water out of the
pump.
2. Run a 50% solution of a RV or
non-toxic/biodegradable antifreeze
through the pump.
3. Flush the pump with fresh water
before the next use.
4. In freezing conditions failure to
do this may cause internal pump
damage.
5. For long periods of storage in
non-freezing areas the solution
will keep the seals and O-rings
lubricated.
Service Pumps
Servicing the Valves
The inlet and discharge valves in this
series pumps are all the same. The
valves are located under the six 19mm
hex plugs. The inlet valves are located
on the inside portion of the head under
the seal assemblies and the discharge
valves are located on the top row of the
pump head.
Tools required: #8-32x" machine screw
and diagonal pliers, screw driver, 19mm
socket, ratchet, and torque wrench.
Discharge Valve
Removal:
1. Remove the valve cap.
(See Figure 5)
2. Inspect the valve cap O-ring for
any damage, replace if necessary.
3. Screw the machine screw into
the hole on top
of the valve cage
(approx 1/8"). Using
the diagonal pliers
grasp the screw at
the lowest reachable
point. Using the pump
head as a base, push down on the
pliers, the valve will lift out. (See
Figure 6)
4. Use a small probe to
move the poppet up
and down to assure
that the valve is
functioning properly
and that no debris is
stuck in the valve. (Figure 7)
5. Inspect the valve O-ring for any
damage, replace if necessary.
Discharge Valve Assembly:
1. Insert the valve
assembly squarely
into the port pushing
it into place with a
deep well socket (you
will feel the valve
assembly seat). (See Figure
8)
2. Install the valve
cap and torque
to the proper
specifications. (See
Figure 9)
