Eaton PVH Variable Displacement Piston Pumps Vickers ...
www.eaton.comhigh performance pumps are a family of variable displace-ment, inline piston units that incorporate the proven design, quality manufacturing techniques and operating features of other Vickers piston pumps, but in a smaller, lighter package. The PVH series has been spe-cially designed to meet the 250 bar (3625 psi) continuous
Wastewater Technology Fact Sheet: In-Plant Pump Stations
www3.epa.govSeveral types of variable-speed pumping equipment are available, including variable voltage and frequency drives, eddy current couplings, and mechanical variable-speed drives. Variable-speed pumping can reduce the size and cost of the wet well and allows the pumps to operate at maximum efficiency under a variety of flow conditions.
Axial Piston Pumps - Advanced Fluid Systems
www.advancedfluidsystems.comBoth fixed and variable displacement models make up this range of axial piston pumps. Their high performance ratings and efficiencies are achieved with a variety of hydraulic fluids. Fixed displacement models are noted for their volumetric and mechanical efficiencies. Variable displacement models can closely match pressure and/or flow

Collection Systems Technology Fact Sheet: Sewers, Lift Station
www3.epa.govBecause variable-speed pumping allows lift station discharge to match inflow, only nominal wet-well storage volume is required and the well water level is maintained at a near constant elevation. Variable-speed pumping may allow a given flow range to be achieved with fewer pumps than a constant-speed alternative. Variable-speed stations

Variable Volume Chilled Water Pumping System Controls
daytonashrae.orgMultiple Variable Speed Secondary Pumps. 2-way valves at all chilled water coils and secondary bypass loop with 2-way valve. • Each primary pump pumps water through a chiller. These can be piped so either pump can work with either chiller if isolation valves are used at each chiller or with dedicated primary pumps for each chiller.
