DCP Series

With the Drive Controlled Pump, Parker offers speed-controlled, hydraulic full-system solutions that are tailored exactly to a predefined circle in advance. Thus, they provide high energy efficiency, reduced noise emissions and lower component costs.

Drive Controlled Pumps essentially consist of three components: an AC drive unit (frequency controller and electronics), an asynchronous or synchronous motor, as well as a hydraulic pump. The pump can be either a vane pump – in single or multiple design – or a variable displacement axial piston pump. Drive Controlled Pumps enable the central, regulated hydraulic supply of all drives. Thus they provide the exact power that is required in the cycle at all times.

Markets:
• Industrial
• Molding

Features/benefits:
• Less motor and cooling power required – ensures significant energy savings
• Speed reduction at partial load – reduces noise emissions, increases component lifetime
• Smaller components with higher energy density – reduces investment costs
• Optimum adjustment to cycle requirements – higher precision and dynamics
• Free Parker DriveCreator software – enables optimum dimensioning of all components

Applications:
• Machine tools
• Die cast
• Presses
• Injection molding
