The range will set new standards for energy efficient and ultra quiet performance.

The compact and innovative K3VL open circuit, axial piston pumps enable a rated pressure capability as high as 320 bar.

A range of integral control options includes torque limit, pressure compensation and load sensing.

Additional variants offer integral unloading and remote proportional relief functions.

Pioneering technology has been utilised in the development of the rotary group and valve plate to ensure considerable reductions in fluid pressure pulsation.

With pressure pulsation being the primary cause of airborne noise, this significant design feature offers a typical noise reduction of 5dB(a) over conventional pump designs.

The K3VL range is available in displacements from 45 to 140 cc/rev with a complete range of ISO and SAE input shafts, mounting flanges and through drives.

The new pumps have a variety of technical features that give important benefits.

These include solid pistons that reduce dead volume under compression and thereby increase volumetric efficiency.

Opposed piston stroking reduces structural deflections and swash plate support loading and the large size ensures optimal on-stroking response characteristics.

The extensive surface area and hydrostatic bearing of the pillow-type support mechanism reduce frictional loading and vibration, thus contributing to the reduced noise emission.

The pumps have heavy-duty long life roller bearings and a low resultant reaction force for the rotating group mechanism.

A variety of highly responsive pressure and load sense regulator options include dual-spool controls as well as unique, integrated unload and remote proportional pressure pilot options.

Standard ISO and SAE mounting and porting are used to guarantee maximum acceptability and standardised SAE interfaces and adapter kits are provided for a variety of through drive options.

The interface design typically ensures that an additional pump of power capacity similar to that of the base pump can be connected to the through drive, thereby providing a highly flexible build capability.

A separate dual spring type torque limiter control option is available.

As this is ported internally to the dual spool regulator, a wide range of control options is possible without sacrificing compactness.

The individual springs of the self-compensating piston return mechanism allow consistent shoe contact with the swash plate, producing 320 bar continuous running capability and minimal wear for a long, maintenance-free service life.

The patented rotating group timing method employed by the K3VL models dynamically ensures that the output flow pulsation is inherently sinusoidal, with a negligible higher frequency content.

Fluid-borne noise and consequent airborne noise emissions are thereby minimised.

The optimally balanced, spherical valve plate ensures ideal cylinder block contact, resulting in excellent axial stability, reduced bearing reaction force and a high self-priming speed capability.The news come from http://www.bossgoo.com/
