DISASSEMBLY:
STEP 1.
Figure 1
Before disassembly, note orientation of center housing. This
portion of the pump is reversible and noting direction now may
prevent additional assembly time later. Remove muffler by turning
counter-clockwise by hand.
CAUTION:
Before any maintenance or repair is attempted, the
compressed air line to the pump should be disconnected and all air
pressure allowed to bleed from the pump. Use extreme caution as
the pump liquid path may still be under pressure even though air line
is disconnected. Disconnect all intake, discharge, and air lines. Drain
the pump by turning it upside down and allowing any fluid to flow
into a suitable container. Be aware of any hazardous effects of
contact with your process fluid.
The UX conductive plastic pumps are available with conductive
polyethylene wetted parts.
TOOLS REQUIRED:
Metric Socket Wrench Set
Metric Open-end / Box-end Wrench Set
Adjustable Wrench
Medium Flat Head Screwdriver
Air Valve Tool Included with Pump
NOTE:
The model used for these instructions incorporates Teflon
®
diaphragms, balls, and seat o-rings. Models with rubber
