Disassembly
Use
Figure 2
, (Page 3) to identify main pump components and
Figure 3
, (Page 4) to
identify O-ring locations.
1.
Reverse assembly sequence, taking care to position pump to retain check balls
during removal of valve seats and stops. A screwdriver can be used if necessary to
remove the inlet valve seat.
2.
Pull the PE bladder off of the pump head barb by pulling firmly, then discard.
Cleaning / Decontamination Note
If it is desired to operate the pump outside the well, such as in a pail for decontamination
purposes, the operating pressure of the pump should be reduced to 35 PSI or less to
avoid rupturing the bladder
Attaching Tubing
A tubing insertion tool is provided to make the small-diameter tubing used on this pump
easier to grip and push into the pump. The tool is shown in
Figure 4
.
1.
Cut both tubes to equal length; cutting the tubes at a slight angle will make insertion
easier.
2.
Grip the ¼” tube ONLY in the large groove in the insertion tool, leaving ¾-1” of tubing
extending from the end of the gripping jaw.
3.
Hold the insertion tool at the jaw end of the tool, FORWARD of the tool’s pivot point,
squeezing the jaws together.
4.
Push the ¼” tube into the pump while rocking the tool slightly Watch and feel for the
tube to push ¼” past the point of initial resistance into the pump.
5.
Pull back on the tube to check that it is inserted firmly.
6.
Repeat for the 1/8” air tube.
