Variable Volume Piston Pumps


Daikin type piston pumps
Daikin type piston pumps

This piston pump is applied for
NC lathe
Machine center
Bending machine
Blowing machine
High efficient special machine or press
Flow range is from 15cc to 70cc/rev


  • Daikin Type.
  • Swash Plate axial type design, widely, used in industrial machinery.
  • Specially designed for low noise through whole pressure zone.
  • Unique controlling ways make it become save energy circuit.
  • Ideal for small volume tank use as its pressure lose small and rarely rise in oil temperature.

Control Type

Control TypeJIS SymbolCharacteristicsDescription
A Pressure Compensator ControlJIS Symbol - ACharacteristics - A1. When system pressure increase to set-up pressure, flow drops automatically but pressure remains unchanged.
2. Flow and set-up pressure can be adjusted manually.
A-RC Remote Pressure Compensator ControlJIS Symbol - A-RCCharacteristics - A-RC1. Its functions are same as A type; Furthermore, pressure can be remote controlled.
CH Two-stage ControlJIS Symbol - CHCharacteristics - CH1. With low-pressure at large flow and high-pressure at small flow function. A small power electrical motor is suitable enough for it.
2. When system pressure increase or approach to PH pressure, flow of pump will automatically drop to QL.
3. Pressure PH PL or flow QH QL are adjustable.
4. It is ideal to apply on machines which its strokes are long unloaded or short stroke loaded.
CH-RC Remote Control Type Two-stage ControlJIS Symbol - CH-RCCharacteristics - CH-RC1. Its functions are same as CH type; Furthermore, pressure can be remote controlled.
