Series 600 OEM Steering Pump

Designed and developed for the automotive industry, the high performance Series 600 Steering Pump is flexible, compact, lightweight and dependable.
It can be used on all types of commercial vehicles, from light commercial vehicles and vans to Class 8 heavy duty trucks and road trains.

The Series 600 pump is particularly suitable for any large off-highway vehicle within the construction, mining or agricultural sectors, which utilises a steering axle or steering ram. It is also suitable for marine applications. Created for the road, perhaps the Series 600 Pump’s toughest assignment though has been inclusion in US Humvee and Stryker military vehicles.

Modular Design

The modular design and concept of the Series 600 Pump makes it very flexible for packaging into many applications. Constructed from cast iron and aluminium, the design is of modular concept in order to provide flexible mounting and drive installations for the vehicle designer. Various mounting flanges and drive options are available to meet international standards of SAE and DIN specifications.

The Series 600 pump can be specified with many options, such as a rotation of clockwise or counter-clockwise, left or right hand discharge, and with reference to the published model matrix the pump can be specified with any combination of features to meet the vehicle designer’s requirements. Also, to minimise installation time and reduce costs, the rear cover can become an integral mounting bracket and the drive shaft can be extended to drive further air, vacuum or hydraulic pumps.

The base pump design provides typical discharge flow rate and pressure relief performance characteristics that are common throughout the range regardless of the application and end user.
