Hydraulic Pump
Original Kawasaki Professional Design & Standard Parameters
Built based on Kawasaki’s original K5V200DP design blueprint and strict manufacturing standards, adopting a dual-variable axial piston plus gear pump composite structure, fully retaining the original technical parameters and performance characteristics. There is no deviation in flow, pressure and displacement data, ensuring seamless matching with the original hydraulic system of supporting equipment, and stable operation without conflicts after installation, fully restoring the original power performance of the equipment.
High Flow & High Power Output for Large Equipment
With a single pump displacement of 200cc/rev and a total displacement of 400cc/rev, the maximum total flow can reach 508 L/min at 1800rpm, providing strong and sufficient hydraulic power for 25-40 ton large excavators and special equipment. It ensures efficient execution of actions such as excavation, walking, rotation and lifting, even under heavy-load conditions, without slow action or insufficient power, greatly improving construction efficiency.
Kawasaki K5V200DP bivariable axial piston hydraulic pump (OEM Part Number 422-1296) is a high-performance original standard replacement hydraulic main pump, specially designed for large and medium-sized construction machinery and special hydraulic equipment. This pump is widely compatible with a variety of mainstream brand models, including Caterpillar 329D2 L, 330D2, 330D2 L, 336D2 L excavators, SANY SY335 excavator, VOLVO EC460BLC/EC480D excavator, Kobelco SK240LC-12 excavator, XCMG XE335C excavator, as well as C8 on-board concrete pump trucks, generator sets equipped with 3512B engine, and mobile hydraulic power units matched with 330D2 models. It can be used as a perfect substitute iterative product for Hengli HPL-200/K5V200DP-E hydraulic pump and Rexroth A11VO190 hydraulic pump, with consistent installation dimensions and stable performance matching, providing a cost-effective replacement choice for equipment maintenance and upgrade. Adopting Kawasaki’s mature hydraulic technology, this pump integrates high efficiency, durability and stability, fully meeting the high-intensity and long-cycle operation needs of large construction machinery, and ensuring the smooth operation of hydraulic systems under various complex working conditions.

Graded Pressure Design for Multi-Circuit Adaptation
Adopting targeted graded pressure configuration, the main oil circuit and traveling circuit pressure are both 35 MPa, and the rotary circuit pressure is 27.5 MPa, which fits the hydraulic pressure demand of each working circuit of large excavators. This design can effectively balance the pressure distribution of each circuit, avoid pressure overload or insufficient power, protect the hydraulic components and extend the overall service life of the hydraulic system.
Perfect Matching with Caterpillar C7.1 Engine
Specially calibrated and optimized for the Carter C7.1 engine (156kW/1800rpm), the power output and speed parameters are highly matched, achieving efficient energy conversion between the engine and the hydraulic pump. It reduces energy loss and fuel consumption during operation, ensuring stable linkage between the power system and the hydraulic system, and is especially suitable for Caterpillar series excavators equipped with this engine.
Sturdy Structure & High Durability
The whole pump is made of high-strength wear-resistant alloy materials, with key components such as piston, cylinder block, valve plate and swash plate processed by precision machining and special heat treatment. It has excellent wear resistance, pressure resistance and impact resistance, and can withstand long-term high-intensity operation in harsh construction environments such as mines, earthworks and road construction, with low failure rate and long service cycle.
Wide Model Compatibility & Multi-Scenario Application
Not limited to a single brand of equipment, it is widely compatible with Caterpillar, Sany, Volvo, Kobelco, XCMG and other mainstream 25-40 ton excavators, and can also be applied to concrete pump trucks, 3512B generator sets, 330D2 mobile hydraulic power units and other supporting equipment. It covers a variety of construction scenarios, meeting the diversified supporting and replacement needs of global customers.
Ideal Replacement for Mainstream Alternative Models
Can directly replace Hengli HPL-200/K5V200DP-E and Rexroth A11VO190 hydraulic pumps, with consistent installation dimensions, flange interface and pipeline connection, no need for secondary modification or adjustment. It provides a reliable backup option for customers who cannot purchase original parts, reducing maintenance costs and equipment downtime.
Reasonable Weight & Easy Installation & Commissioning
The total weight is about 320kg (including gear pump), with a compact and reasonable overall structure design, conforming to the installation space standards of 25-40 ton excavators. The integrated forming of the pump body reduces the difficulty of installation and disassembly, and the factory has completed pre-commissioning, which can be quickly put into use after installation, saving labor and time costs for maintenance and commissioning.
