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. 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 Wilden model A2 is an air-operated, double-diaphragm pump with wetted
parts of aluminum, stainless steel and Alloy C. The single-piece center section,
consisting of center block and air chambers, is molded of polypropylene or
aluminum. All O-rings used in the pump are of a special material and shore
hardness that should only be replaced with factory-supplied parts.
PLEASE read all directions before starting disassembly.
NOTE:
The model used for these instructions incorporates PTFE diaphragms,
balls and seats. Models with rubber diaphragms, balls and seats are the same
except where noted.
NOTE:
Replace worn parts with genuine Wilden parts for reliable performance.
Step 1
Before starting disassembly, mark a line from each liquid chamber to
its corresponding air chamber. This line will assist in proper alignment
during reassembly.
