Danfoss PVM Piston Pump Applications: How Variable Displacement Hydraulics Power Industrial Machinery
Discover how the Danfoss PVM variable displacement piston pump supplies controllable hydraulic power for injection molding, metal forming, mining, conveyors, oil & gas equipment, wood processing and industrial hydraulic power units.
Danfoss PVM Piston Pump: From Hydraulic Power Source to Machine Performance
In many industrial machines, the hydraulic pump is the component that converts mechanical power into controllable hydraulic energy. When a machine needs to lift a heavy load, clamp a workpiece, drive a hydraulic motor, feed material or perform a pressing operation, the hydraulic pump determines how effectively hydraulic flow and pressure can be delivered to the actuators.
The Danfoss PVM piston pump is a variable displacement open-circuit axial piston pump designed for industrial hydraulic systems. Its variable displacement design allows hydraulic output to be matched with machine requirements, making the PVM suitable for applications where controllable flow, pressure and reliable power transmission are required.
Converts mechanical input power into hydraulic flow and pressure for cylinders, hydraulic motors and other machine actuators.
How the PVM Pump Works in an Industrial Hydraulic System
Where Is the Danfoss PVM Piston Pump Used?
The PVM platform can be integrated into different industrial hydraulic circuits. Its actual function depends on the machine design, control configuration and selected displacement.
Injection Molding
Supplies hydraulic power for mold clamping, injection, mold opening, closing and ejector movements in hydraulic injection molding machines.
Metal Forming
Provides hydraulic flow for pressing, bending, forming, clamping and positioning operations on industrial metal-forming equipment.
Mining Machinery
Supports hydraulic cylinders, material-handling mechanisms, positioning systems and auxiliary hydraulic functions in mining equipment.
Conveyor Systems
Supplies hydraulic flow for hydraulic motors, belt tensioning systems, lifting functions and material positioning equipment.
Oil & Gas Equipment
Acts as a hydraulic power source for hydraulic power units, actuation systems, positioning and other industrial oilfield functions.
Primary Metals
Supports lifting, clamping, positioning, pressing and material-handling functions in steel and primary metal processing equipment.
Wood Processing
Provides hydraulic power for log handling, clamping, feeding, positioning and other hydraulic functions in wood-processing equipment.
Hydraulic Power Units
Can be integrated into industrial HPUs together with motors, reservoirs, filters, valves, manifolds and other hydraulic components.
Industrial Machinery
Suitable for hydraulic circuits requiring controllable flow and pressure for cylinders, motors and other industrial actuators.
What Does the PVM Pump Actually Do?
The PVM pump acts as the hydraulic power source of an open-circuit system. It draws hydraulic oil from the reservoir and delivers controlled flow to the machine's hydraulic control circuit.
Depending on the system configuration, this hydraulic energy can be converted into linear motion through hydraulic cylinders or rotary motion through hydraulic motors.
PVM Pump in an Industrial Metal-Processing Hydraulic Power Unit
Consider a metal-processing machine equipped with a hydraulic power unit. The machine needs hydraulic force for workpiece clamping, tool positioning and cylinder return movements.
During clamping, the hydraulic system needs sufficient pressure to generate the required force. During positioning and return movements, the flow requirement can be different. A variable displacement piston pump such as the PVM can therefore be integrated into a system where hydraulic output needs to respond to changing machine conditions.
