K7v140DTP Hydraulic Variable Displacement Piston Pump

K7V140DTP Hydraulic Variable Displacement Piston Pump overview overview

The K7V140DTP Hydraulic Variable Displacement Piston Pump is a high-performance swashplate-type axial piston pump from Kawasaki’s K7V series, engineered for 30–35 ton heavy-duty construction machinery. Featuring load sensing and pressure control, it delivers a nominal displacement of 140 cm³/rev with a rated pressure of 350 bar and peak pressure of 400 bar, ensuring stable high-pressure flow output. Its optimized design offers high efficiency, low noise, and exceptional durability, with reinforced shaft and heavy-duty bearings for extended service life. Ideal for excavators, drilling rigs, and loaders, it excels in harsh environments like mining and infrastructure, providing reliable power for complex hydraulic systems. 

Core Features & Advantages

• High Efficiency & Low Noise Operation：Adopting Kawasaki’s proprietary optimized technologies, it achieves world-class

  volumetric and mechanical efficiency, effectively reducing fuel consumption. The optimized fluid passages and noise-damping

  structure significantly lower operating noise compared to peer products, enhancing operator comfort.

• Heavy-Duty Durability & Long Service Life： Equipped with high-load capacity bearings and an upgraded, reinforced drive
  shaft, it greatly reduces bearing edge loads. The cylinder block, pistons, and swashplate are made of wear-resistant alloy with
  special heat treatment, ensuring stable performance in harsh conditions such as mining and infrastructure sites, with a service
  life of over 15,000 hours. 

• Precise Control & Wide Compatibility：Load sensing control dynamically adjusts flow and pressure based on actual actuator

  demands, eliminating unnecessary energy waste. It supports tandem/parallel multi-pump configurations, with SAE-standard

  mounting interfaces compatible with Sany, XCMG, Kobelco, and other OEMs. Only the OEM part numbers differ, while core

  performance remains consistent.

FAQ

1.How does the variable displacement work?

The pump's flow is adjusted by changing the angle of an internal swash plate. As the swash plate angle changes, the stroke length of the pistons varies, which in turn changes the volume of fluid displaced per rotation, allowing the flow rate to adapt to the system's needs.
