MODEL T2 METAL

DIRECTIONS FOR DISASSEMBLY/REASSEMBLY

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.
