EATON 25-50M vane motors are high speed, high pressure motors offer a choice of 12 torque ratings from 4,7 to 33,9 Nm/6,9 bar (42 to 300 lb. in./100 psi); speeds from 400 to 3600 r/min continuous and 4000 r/min intermittent; pressures to 155 bar (2250 psi) continuous and 172 bar (2500 psi) intermittent; reversible shaft rotation; flange or foot mounting.
High Efficiency
A unique dual pressure plate design results in low internal leakage and
overall operating efficiencies up to 90%. Efficiency varies with motor size, pressure, speed, and fluid viscosity and temperature.
Mounting Flexibility
The motor’s cover can be assembled in four positions with respect to the body. Changing port positions is accomplished by simply rotating the cover, and the cartridge which is pinned to the cover, in 90° increments, thus providing the optimum mounting for connecting piping.
Easy to Service
The drive cartridge is accessible by removing the motor’s cover and can normally be replaced in ten minutes without removing the motor from the machine. The torque capability of motors within the same model series can be changed by changing the cartridge or cam ring.
Low-wear Design
25M - 50M motors are hydraulically balanced to reduce wear and heat-producing friction. All internal inlet chambers are equally and diametrically opposed. As a result, pressure induced radial loads are balanced. Shaft bearings only have to carry external loads so wear is greatly reduced.
Proven Reliability
For more than two decades, the reliability of these high performance motors has been field proven on a variety of machinery applications.
