A Series Aluminium Gear Pumps

Hydreco is specialised in aluminium pumps from group A1 to group A3, divided into 34 displacements: from 0,9 to 120 cc/ rev, and up to 320 bar of max working pressure. Pumps are available with cast iron flanges and covers version to reduce the noise level. Hydrostatic balance takes up axial slack through the pressure supplied to a defined bushing area. Bearings lubrication is automatic and proportional to the pump operating pressure. Each pump can be assembled with standard flanges (European, German or SAE) or with special ones (ZF, Perkins and Renault), with tapered, cylindrical or splined shafts. Furthermore it is possible to assemble covers with pressure relief valves and flow control valves.
All standard pumps are arranged to drive a supplementary pumps, using the coupling kits, available also as a short version.
