Albany is a leading manufacturer of standard & special purpose pumps for a very wide range of fluids. The company owns the Stothert & Pitt screw pump designs and makes exact replacement pumps. Their screw pumps are fitted with hardened and ground timing gears and located bearings to ensure there is no contact between the screws. The central discharge means the shafts are hydraulically balanced to eliminate any end thrust and the mechanical seals (or packed glands) are under inlet pressure. Integral relief valves and various heating methods are an option.
