Features High Pressure Capability Most SMA motors are designed for continuous 350 bar & intermittent 490 bar duty. Will withstand higher peak pressures High Power Capability Designed for continuous high power use. High Speed Range Designed to operate over a wide speed range. Up to 150:1 for standard models. Up to 250:1 for some special models. High Efficiencies Minimal no load pressure drop even at high speed. Efficient design based on hydrostatic & taper roller bearings.
