Solutions

Positive Displacement pumps by John Brooks Company are commonly used for pumping high-viscosity fluids such as oil, paints, resins or foodstuffs. They are preferred in applications where accurate dosing or high-pressure output is required. The production of a pump is not affected by pressure and is selected where the supply is irregular. These pumps function to move fluid by repeatedly enclosing a fixed volume, with the aid of seals or valves and moving it mechanically through the system. The pumping action is cyclic and is driven by pistons, screws, gears, lobes, diaphragms or vanes. There are two main types: Reciprocating and Rotary.
