Wilden offers its Stallion Series Solids Handling Air-Operated Double-Diaphragm (AODD) Pump. Stallion pumps are designed to excel in harsh mining environments and have a history of successful use in metalliferous, coal and other open-cut and underground mines in site dewatering and general transfer applications. The pumps are ideal for use in mining operations because they have handles that allow easy movement of the pump and a screen base that keeps larger-than-acceptable solids from entering the fluid inlet. The screen bases are constructed of polyurethane, which absorbs the shock – and decreases the possibility of damage – when the pump is dropped into a hole for dewatering. Stallion pumps also feature Wilden’s Pro-Flo X Air Distribution System (ADS), which maximizes pump flexibility and control through its patented Energy Management System (EMS). Stallion pumps are available in three sizes – PX4 (1-1/2 in.), PX8 (2 in.) and PX15 (3 in.) – with flow rates ranging from 305 L/min. (81 gpm) to 776 L/min. (205 gpm), suction lifts from 5.7 m (18.6 ft.) to 9.2 m (30.1 ft.) and maximum discharge pressures to 125 psi. The pumps can handle solids from 13 mm (1/2 in.) to 25 mm (1 in.) in size.
