Hydraulics

Features
The OSPD is equipped with two rotary meters (gearwheel sets).
In the absence of pump supply, only one rotary meter is active for emergency steering.
Under normal steering conditions, both rotary meters are active.
With the OSPD, even heavy vehicles can, in many cases, comply with regulations and be steered without the emergency pump.
Ratio between normal and emergency steering displacement: from 2 to 7
Low noise level
Good steering controllability
Low steering torque: from 0.8 to 3.0 N·m
High return pressure possible: up to 40 bar
One or more integrated valve functions available:
Pressure relief valve
Shock and suction valves in L + R
Check valves in P and LS

Features and benefits 
With two rotary meters, heavy vehicles can often be steered without an emergency steering pump 
Low noise 
Good steering controllability 
Low steering torque 0.8 Nm to 3.0 Nm [7.08 lbf-in to 26.6 lbf-in] 
High back pressure up to 40 bar [580 psi] 
One or several built in valve functions possible: pressure relief, shock, and suction in L + R; check valve in P and LS 
Applications 
Small tractors 
Backhoe loaders
Road building machinery 
Combines and harvesters

Features
The OSPD is equipped with two rotary meters (gearwheel sets).
When the pump is not supplying power, only one rotary meter is active for emergency steering.
Under normal steering conditions, both rotary meters are active.
With the OSPD, even heavy vehicles can, in many cases, comply with regulations and be steered without an emergency pump.
