Parker’s new hydraulic motors boost cooling efficiency for on- and off-highway equipment
Parker Hannifin, leaders in motion and control technologies, have launched their latest range of hydraulic motors, developed to improve the efficiency and performance of fan-operated cooling systems in both on- and off-highway vehicles.
The new M5A hydraulic motors are suitable for use with fan units of up to 20kW, at maximum operating pressures of 300 bar (4,500 lb/in2) and speeds to 4,000 rev/min. In addition, they are compact, lightweight and based on proven technology to offer a cost-effective and reliable solution for both OEM and retrofit applications.
The new M5A hydraulic motors are designed to offer high levels of engine efficiency by allowing the speed of cooling fans to be matched precisely to the operating load of each vehicle; this can significantly reduce energy consumption and emissions, while helping to improve fuel economy and minimize the wear on moving parts, to extend service intervals.
Each motor is manufactured from a tough cast iron housing and incorporates heavy-duty components throughout, including specially developed bearings, resulting in a robust system capable of handling sustained heavy loads. For example, the bearing and motor shaft assembly is capable of withstanding high gyroscopic forces, making the system suitable for use in construction equipment.
Similarly, in order to meet the increasingly rigorous noise and emission standards required in the commercial vehicle sector, the new motors use proven radial vane technology to allow them to operate at particularly low noise levels, even under full load.
The M5A motors feature integrated proportional pressure relief valves and sensor mechanisms. These provide extended functionality, for example anti-cavitation and dedicated speed control, without the need for auxiliary equipment. For applications where cooling radiators are prone to clogging with dirt or debris, a reverse valve option is also available, which allows radiators to be cleaned simply by reversing the air flow from the pump and fan assembly. Again, the reverse valve is integrated within the motor housing, minimizing system size still further.
The new M5A hydraulic motors have been developed for use with original equipment from all major vehicle manufacturers, and are supplied in two industry standards sizes: SAE A and SAE B.
