The PH Series is a low-noise variable displacement piston pump with rated pressure of 28 MPa. This series was developed based on the low-noise P**V seris which has won high reputation from various customers. The PH Series also feature lower noise levels, and more compact size.

• Low operation noise: highly rigid pump construction and　proprietary noise reduced design enables low operational sound levels.
  
• Long life: high efficiency design with 28 MPa rated pressure.
  
• To improve their resistance to contamination, these pumps use bushed cylinder blocks made of wear-resistant copper alloy. They also feature a long-life design thanks to the bearings with their high load capability.
  
• Superior controllability: in addition to pressure compensator control, load sensing control, and electric direct control, torque limiter control is also offered.
  
• Wide array of configuration: direct coupled same displacement double pump, direct coupled fixed double, triple pump combinations.

The PH**F Series is a fixed displacement version of the PH variable displacement piston pumps designed for Direct Drive Systems, with more lighter weight and more compact size.

• Compared with the PH series, this series of pumps is designed to have about 40% less weight.
• They also incorporate relief valves to achieve a safety design that protects the hydraulic circuit from overloads.

The P**V Series high performance variable axial piston pump offers a wide range of displacements, a wealth of features, energy-saving design, low noise, high speed, electronics compatibility to meet the diverse needs of users in the machine tool, general industrial machinery, mobile construction markets, etc.

• Low noise: approx. 68.5dB(A) [P70V] at pressure, 21 MPa and speed, 1800 min-1.
  
• Offers many types of pump control functions: (single stage, multi-stage, proportional) pressure compensator control, load sensing control, dual pressure dual flow self-pressurized control, electric direct control, etc. In addition, configurations which include manifold blocks which incorporate various function valves can be mounted at the delivery port, with a capacitor-like function which reduces pulsations are possible which simplify hydraulic circuits and reduce noise.
