MOTORS AND ACCESSORIES
• The performance values listed below are for continuous use conditions. See the drawing for performance curves, including peak and intermittent values. • The optimal operating condition is 1/3 to 2/3 of the continuous use values. • Standard rotation is clockwise (facing the shaft) when port A is pressurized. • Standard shaft seals for the BM2 Series are rated to 1,085 PSI. HPSS to 2900 PSI. • Case drains relieve internal oil leakage and prevent housing overpressure, protecting seals and extending motor life. • Standard shaft seals and bearings are not recommended for applications that may experience side-loadings. • Internal check valves are included for smoother directional control. The BM2’s is a medium, spool valve type gerolor motor, that can bear higher pressure than BM1. This motor achieves optimal efficiency and economy for medium load applications.
