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 T2 has a 25 mm (1") inlet and 19 mm (
³⁄₄
")
outlet and is designed for flows up to 95 lpm (25 gpm). The
single-piece center section, consisting of center block and air
chambers, is molded of polypropylene or aluminum. The air
valve is manufactured of brass or high-tech, engineered ther-
moplastics. All o-rings used in the pump are of a special mate-
rial and shore hardness that should only be replaced with
factory-supplied parts.
