Wilden Original Series T2 Metal Air-Operated Double-Diaphragm Pumps Meet the Needs of Various Wastewater Applications

This 25-mm (1”) pump has wetted housings, water chambers and manifolds that are constructed of aluminum, making it the best choice for solid-laden wastewater-treatment applications. Non-wetted housings are constructed of brass and aluminum. The pump offers flow rates to 132 lpm (35 gpm) and can handle pressures up to 8.6 bar (125 psi). It has maximum suction-lift capabilities of 5.18 m (17’) for dry products and 9.45 m (31’) for wet products, while being able to handle solids with diameters reaching 3 mm (1/8”). Elastomer options include Buna-N and Neoprene.

Wilden’s T2 Series pumps are equipped with the Turbo-Flo air-distribution system (ADS). This ADS operates on differential pressure only, meaning there are no mechanical trip rods, bearings or springs that can wear and need repair. It has an externally serviceable air-valve that is attached to the center block, which houses specialized Glyd ring seals. The air-valve piston within the air-valve body routes the air supply to one of two air chambers, as dictated by its position. Built-in air-valve tolerances allow for the passage of some moisture and air-line particulates, allowing free movement of the air valve.
