5.1 PUMP MAINTENANCE
The pump is a mechanical device and will require maintenance over time. In general it is
a good practice to replace pump tubes every 6 months. If flow decreases noticeably,
check pump tubes for deterioration. The pumps are manufactured with the pump tubes
pre-lubricated THEY SHOULD NOT NEED EXTRA LUBRICATION! If lubrication should
become necessary, use a high grade silicone-based grease. DO NOT lubricate the pump
tube with petroleum based lubricants. These will cause pump tube failure!
5.2 PUMP TUBE REPLACEMENT
To replace a pump tube, follow the procedure below.
1.
Turn off power to SR6000S.
2.
Remove chemical supply and injection tubing from ¼” fittings.
WARNING these
lines maybe pressurized wear protective equipment to protect the eyes, face, and
hands from chemical spray! Use caution when disconnecting lines!
3.
Remove the lower left and upper right 1-5/8” screws from the pump cover to
remove the pump from the SR6000S.
4.
Remove the remaining two 1-1/4” screws from the pump cover. Lift on cover lip
and snap cover off of the pump housing.
5.
With touching the spring remover pump rotor assembly.
6.
Remove tube from pump housing by working loose the tube stems from the
housing.
7.
Install new tube, making sure tube stems are locked into housing tube stem
collars. DO NOT put any twists in the tube during installation.
8.
With high grade silicone-based grease lubricate the housing hole and the cover
hole for the rotor assembly shaft, and wherever rollers touch the pump tube.
9.
Install rotor assembly by pressing roller against tubing at the top of the pump
housing.
10.
Seat rotor shaft in pump housing hole.
11.
Snap pump cover in place over rotor and housing and install two 1-1/4” screws in
upper left and lower right. DO NOT over tighten!
12.
Using a large bladed screwdriver placed in the “X” on the top of the rotor shaft,
turn the rotor assembly to see that pump is moving properly.
13.
Place pump on dispenser motor shaft so that motor shaft mates with pump rotor.
Rotate pump (NOT motor shaft) so that upper right and lower left pump cover
screw holes align with holes in SR6000S.
14.
Install lower left and upper right 1-5/8” screws from the pump cover to the
SR6000S. DO NOT over tighten!
15.
Reinstall chemical supply and injection tubing to the ¼” connections on the pump.
