Has testing been performed in Vane pumps, Piston pumps and Gear pumps?
Yes, all pump manufacturers provide recommendations on pump selection based on the pressure, flowrate and work output demanded by the system. Proper pump selection typically assumes that the fluid in use will enable the pump to work at >80% efficiency. Pump manufacturers have tested all of their pump models using various fluids at several temperatures and provide recommendations on minimum viscosity requirements which are required to maintain reasonable efficiency. A number of technical papers have also been published which document the significant impact of operating viscosity on pump efficiency over a full range of temperature and pressure conditions in all pump types. Additional details can be found in the “Supporting Technical Information” section.
