Windust Hydraulics supply the Vickers V2010 and V2020 series fixed displacement double vane pumps by Eaton, which are of the Vickers balanced vane type construction.
Double pumps provide a single power source capable of serving two separate hydraulic circuits, or of providing greater volume through the combined delivery of both sections. In either type of
application, two pumps in a single housing result in a more compact, simple installation and can be driven through a single shaft coupling.
V2010 double pumps have capacities of 22.7 to 49.2 L/min and 3.8 to 26.5 L/min for their shaft-end and cover-end pumps, respectively. V2020 double pumps have capacities of 22.7 to 49.2 L/min and 22.7 to 41.6 L/min for their shaft-end and cover-end pumps, respectively.
All models are designed for use with oil or synthetic fire-resistant fluids. Shaft rotation is either clockwise or counterclockwise, but can be changed by modifying the assembly of internal parts.
SAE 2-bolt mounting flanges are standard, and foot-mounting brackets are optional. Many electric motor manufacturers can supply drip-proof or totally enclosed, fan cooled motors with end bells on which the pumps can be mounted.
Internal inlet and outlet pressure chambers are diametrically opposed. As a result, pressure-induced radial loads are balanced, and bearings have to carry the external load only. Low vane tip/ring loading allows high pressure operation. High speeds are possible because the inlet flow paths are designed to give uniform oil acceleration, and thus better filling characteristics, particularly at low inlet pressures.
