Integrated functionality

H1 advantages are not limited to reduced part count and a robust design. The new family of hydrostatic pumps also offers control override, integrated sensors, integrated speed limitation, and improved
charge pump performance. And there is more. H1 pumps allow the same electrical control to be used for the entire family, thereby easing service and operator training. The message is clear:
H1, the heart of your machine, will allow you to expand vehicle functionality, improve efficiency, and reduce overall machine lifecycle costs – beat after beat.

The H1 integral pressure filter head is designed with a filter bypass valve and noncontacting bypass sensor. The pressure differential acting on the filter element also acts
on a spring biased bypass spool. This spool is designed with a magnetic area. When a certain spool position is reached, the magnet closes a switch in the bypass sensor which
allows R2 to be in parallel with R1. This occurs without any mechanical contact between the spool and the bypass sensor.

The H1 axial piston variable displacement pumps are of cradle swashplate design and are intended for closed circuit applications.
The fl ow rate is proportional to the pump input speed and displacement. The latter is infi nitely adjustable between zero and maximum displacement.
Flow direction is reversed by tilting the swashplate to the opposite side of the neutral (zero displacement) position.
