Reliability, efficiency, and robust materials

Kawasaki K3VG series pumps are positioned as a leading hydraulic solution for industrial applications, ensuring optimal performance, efficiency, and long-term durability. They are developed based on the K3V Mobile series, of which over 700,000 units have been supplied to the construction machinery market.

Some of their key qualities include:

Reliable high-pressure and long-lasting design: the K3VG series incorporates high-capacity load bearings and a friction-free piston shoe mechanism, ensuring reliability and a long operational lifespan
High efficiency and excellent self-priming capability: this type of pump features a spherical-shaped swashplate and improved hydraulic balance, ensuring stable cylinder rotation. This allows for high efficiency even under low-pressure and low-speed conditions. Additionally, the spherical shape of the swashplate reduces peripheral speed and pressure drop, significantly enhancing self-priming capability.
Wide range of regulators: mechanical and electronic pressure, flow, and power constant regulators are available

What data do I need to request a Kawasaki pump?

Send us the Kawasaki code or the code of the pump you use today: we check displacement, pressure, flange, shaft and regulator before proposing the solution.

Which regulators are available?

Depending on the series: pressure cut-off, load sensing, torque limiter, power control, electro-proportional pressure control and electric displacement control. The K3VL also offers integrated unloading and an integrated proportional relief valve.

Can multiple pumps be built?

Yes. K3VL and K7VG have an SAE through drive to couple a second pump; the K3VG can mount an auxiliary gear pump and is available in a double version (180DT and 280DT).

How soon will I receive price and availability?

A technician will reply within 24 working hours. The K3VL series is usually in stock; K3VG, K3VLS and K7VG can be ordered from the supplier.
