Piston pumps are used in a wide variety of fluid handling applications. The majority of these can be broken down into four different categories:
Ratio is the effective area differential between the air motor piston and the lower end plunger rod. An 11:1 ratio indicates the pump air motor piston has 11 times the effective area of the fluid handling piston.
Higher ratio pumps produce higher fluid pressures which allows them to either move higher viscosity fluids or transfer fluids longer distances.
Pump components are constructed of different materials to ensure the pump is best suited for a particular application.
Stainless Steel – Used with corrosive fluids and water-borne materials. Stainless steel is corrosion resistant. It can be heat-treated, hard chrome-plated or Ultra-Coated to improve abrasion resistance.
Carbon Steel – Provides excellent abrasion resistance. It can be heat-treated or hard chrome-plated. Not suited for water-borne fluids and corrosive materials, as it will rust and deteriorate.
Exclusive ARO® Ceramic Ultra-Coating – Our piston pump plunger rods and cylinder tubes feature ceramic ultra-coating extending service life up to twice as long. Available on 2-ball. Standard on 4-ball.
Chrome-Plated Stainless Steel Plungers offer superior resistance to rust and corrosion.
Packing seals are used to seal movement of the plunger rod, both in the throat seal and piston seal areas of the pump. They are made of different materials to ensure chemical and material compatibility to maximize service life.
