Toyooki HPP-VC2V Piston Pump

SKU: Toyooki HPP-VC2V Piston Pump

The Toyooki HPP-VC2V Series is a high-performance variable displacement axial piston pump manufactured by Toyooki Kogyo in Japan. Engineered specifically for precision machine tools, the HPP series stands out for its compact size, extremely low noise levels, and superior energy efficiency. It is the standard hydraulic power source for many Japanese CNC machining centers, lathes, and grinding machines.

Key Features:

Series: HPP (VC2V Type)
Displacement: 8 to 63 cm³/rev
Max. Pressure: Up to 210 bar (21 MPa)
Application: CNC Machine Tools, Hydraulic Power Units.

Product Overview The Toyooki HPP-VC2V Piston Pump utilizes a swashplate mechanism to provide variable flow output. What sets the Toyooki HPP series apart is its sharp cut-off characteristics and quick response time, which are critical for the precise clamping and positioning operations in machine tools. The pump is designed to minimize power loss during the pressure-holding (dwell) phase, contributing to lower oil temperatures and energy savings.

Why Choose Toyooki HPP Series?

Energy Saving: The pump automatically adjusts flow to zero when the system reaches the set pressure, consuming minimal power.
Low Noise & Vibration: Optimized internal structure and robust housing significantly reduce operational noise, improving the factory environment.
High Durability: Built with high-grade Japanese materials and precision tolerances, ensuring a long service life even under continuous cycling.
Compact Design: The integrated pressure and flow compensators make the unit compact and easy to install in limited spaces.

Common Applications:

Machine Tools: Mazak, Okuma, Mori Seiki, Brother (Clamping, Tool change systems).
Industrial Presses: Small precision presses.
Automation: Hydraulic robots and transfer lines.
