ARO® Pro Series air operated diaphragm pumps are ideal for general industrial and OEM installation applications. They can easily pump from clean, light viscosity fluids to corrosive, abrasive medium viscosity fluids and can transfer large particles without damage. Due to their pneumatic motor, they may be used in potentially explosive areas. Most of the ARO® diaphragm pumps are ATEX certified (CE Ex11 2GD X).

    ARO® PRO and EXP Series pumps offer the ability to vary the flow outlet and discharge pressure as slow as 0.26 gallons (1liter) per minute up to 275 gallons (1040 liter) per minute for our larger sizes and adjust fluid pressure up to 125 p.si. (8.6 bar), by using just an air filter/regulator and a needle valve.

    Features

    • Ideal answer to big volume applications – where performance is a must
    • Reliability – Patented ‘unbalanced’ air valve eliminates stalling and freezing
    • Serviceability – Easy access to ball checks and fluid caps for easy maintenance and repair
    • Versatility – Comfort grip handles allow maximum portability
    • Solids-Handling – Capable of pumping semi-solids and solids up to 0.75″ (19 mm).
    • Screened Inlet – Keeps unwanted debris out of the pump
    • Intrinsically Safe – Pneumatic operation provides safe use in hazardous and explosive applications.
    • Power Suction Lift – Designed to evacuate liquids and solids out of critical areas without fail
    • Typical Applications – mining, construction, and general industrial dewatering and solids handling applications

    Pit Boss Dewatering Pumps for Tough Projects

    • This line of air-operated diaphragm pumps was developed especially for mining, construction, sump and other operations where a reliable, portable de-watering and solids-handling pump is an everyday requirement. These dewatering pumps were named the “Pit Boss” for its tough, uncompromising performance and construction.
