K3VG112-110RS-0E00 Kawasaki Axial Piston Pump 112 cm³ 350 ba

Product Overview

The K3VG112-110RS-0E00, K3VG112-13FRS-1EH3 and K3VG63-100RS-1PM1 belong to the Kawasaki K3VG series of swash-plate variable displacement axial piston pumps. Designed for industrial open-loop applications, these pumps support a wide variety of control methods including flow control, pressure control, horsepower control and their combinations, with optional high-precision electro-hydraulic servo regulators. Fully interchangeable with genuine Kawasaki units, they enable direct drop-in replacement without modification to mounting interfaces or piping. Every unit undergoes 100% simulated operating-condition testing to ensure high efficiency, low noise and long service life.

• Port and material-handling equipment
• Any industrial open-circuit application requiring high pressure and variable control

Expert Maintenance Tips

1. Ensure proper drive-shaft alignment during installation; use a flexible coupling and avoid excessive radial/axial loads. Verify correct rotation and suction/pressure port connections.
2. Use anti-wear mineral oil meeting NAS Class 9 or better cleanliness; viscosity range 10–1000 mm²/s. System filtration should be at least 10 μm. Thoroughly bleed air before initial start-up.
3. Regularly monitor suction pressure (≥ -0.01 MPa for self-priming) and case pressure to prevent cavitation or over-pressure. Verify control signals and setpoints.
4. During service, inspect pistons, cylinder block and valve plate for wear; replace complete rotating groups when necessary. Store long-term units in a dry environment and rotate the shaft periodically.
