The V40M: For the Mid-Pressure Range
The new pump has been designed for open-circuits in mobile machines and has a displacement volume of 2.75 in3/rev. Its swash plate design allows for easy fine tuning of the flow rate. With a self-priming speed of 2,900 rpm, it is suitable for applications that require operating pressures up to 3,625 psi but can handle pressures spikes up to 4,600 psi.
The pump is connected to the PTO or directly to the motor by an SAE-B flange. It is available with load-sensing and electric proportional controllers, and is designed to integrate with HAWE’s modular line of valves. Among the options available is a thru-shaft with radial suction and pressure ports for mounting additional variable displacement pumps or auxiliary pumps.
The V40M has a length of 8.2 inches. It fits small spaces making it particularly well suited for applications where a tandem pump is needed if efficient parallel operation of multiple consumers at full load is called for.
V60N-130: High Pressure and High Volume
The newest addition to the V60N series of HAWE's variable displacement axial pistion pumps is ready for high pressure and high volume, with working pressures of up to 5800 psi (6090 psi peak) and displacement volumes up to 8 in3/rev. The pump has a high self-priming speed rating and a quiet operating noise level. Weighing only 68 lbs, this pump is one of the most power dense products on the market.
The V60N-130 is designed for direct flange mounting to the PTO on commercial vehicle transmissions, and includes an integrated torque controller to further safeguard the drive train.
Thru-shaft versions are available for flange mounting additional variable displacement and auxiliary pumps as well. Several different controllers, including an electrohydraulic displacement control, are offered to enhance a variety of applications.
This pump is a part of an energy efficient hydraulic solution that complies with emission regulations Tier 4 and Euro 6.
