Plunger Pumps
Operating Instructions and Parts Manual RSV Series Pumps
Disassembly:
1. First remove the eight
5mm head bolts. (See
Figure 10)
2. Place the screwdrivers
as shown between the
head and crankcase of the
pump, lifting one up
and the other down.
The head should
start to lift off of
the plungers. (See
Figure 11)
3. When you remove
the head you may notice
that some of the water
seals have stayed on the
plungers and some in
the head. To remove
the seals from the
plungers simple turn the
assemblies and pull off.
(See Figure 12)
4. If the seal assemblies
are in the head use
the channel lock
pliers to grab the
seal retainer on the
outside ring, twist
the retainer in either
direction (this is done to
free the retainer O-ring
which is stuck to the manifold) and
lift out. (See Figure
13)
5. With your finger pull
out the white restop
ring. (See Figure 14)
6. With your finger pull the
high-pressure seal and
head ring out of the
head. (See Figure 15)
7. The low-pressure seal
is located in the brass
seal retainer. Using
the mechanics pick, go
in between the seal and
retainer and pull the
seal toward the center
and pull outwards. (See
Figure 16)
8. Remove the seal retainer
O-ring with the
mechanics pick. (See
Figure 17)
Assembly:
1. Install the plastic head
ring into the head
(the flat side is on
the bottom). (See
Figure 18)
2. Install the high-
pressure seal. Place the
seal so the open “V” portion is
toward the head ring. You need
to place the seal at an angle and
pull and push to work the seal into
position with your
fingers (do not use any
tools you may damage
the seal). Make sure
the seal is totally
seated against the head
ring. (See Figure 19 &
20)
3. Place the white restop
ring so it mates to the
top of the high pressure
