Spare parts ► K7SP series Kawasaki Hydraulic parts
Main advantages and scope of application of Kawasaki K7SP series hydraulic pumps
The Kawasaki K7SP series of hydraulic pumps are modern, variable displacient axial piston pumps that belong to the new generation of Kawasaki products. They are specially designed for mobile construction equipment, in particular medium and heavy excavators, and are direct descendants of the K3SP series, with significantly improved characteristics.
Kawasaki K7SP series hydraulic pumps have the following main advantages::
- The new generation - the evolution of the K3SP series
- The K7SP series is an advanced replacient for the K3SP, with improved performance, reliability, and energy efficiency.
- Engineering updates have reduced power losses, improved dynamics and service life.
- Twin pump design
- The housing combines two independent pump sections, which is ideal for excavators (separate control of travel, rotation, handle, etc.).
- Reduces the size and weight of the hydraulic systi.
- High working capacity
- Working pressure up to 350 bar, peak pressure up to 400 bar.
- Higher power density compared to predecessors - more energy for the same size.
- Electro-hydraulic control at a new level
- Support for modern controllers: EPC (Electroproportional control), Load Sensing, hybrid control schies.
- Smooth and precise response to load changes ensures high controllability of the equipment.
- Noise and vibration reduction
- The improved cylinder block design, dampers and optimized channels reduce noise to the lowest possible level.
- Increased operator comfort.
- Energy efficiency and compliance with environmental standards
- Less internal costs, better handling — 5–10% lower fuel consumption compared to the previous generation.
- Compliance with Stage V / Tier 4 Final environmental standards.
- Improved maintenance
- Modular design simplifies service and component replacient.
- Compatibility with electronic vehicle monitoring systis (CAN bus, diagnostics with on-board controllers).
- Reliability in harsh conditions
- Resistance to water hammer, high tiperatures and pollution.
- High service life without major repairs - optimal for construction and mining equipment operating in aggressive environments.
