Series 741 and 743 fixed motors
With displacements from 12 cm3 to 40 cm3 [0.75 in3 to 2.5 in3] and continuous pressure ratings of 210 bar [3,000 psi], Danfoss medium-pressure fixed piston motors are ideal for many applications, including propulsion, fan drives, and seeding and planting. They are particularly useful when continuous rotary motion is needed far from a power source.
Features and benefits
- Compact — easy to install
- Efficient axial piston design
- Numerous options — shafts, ports, shuttle valves, speed pickup
- Optional shuttle, back pressure valve — improved loop cooling, flushing
- Optional speed sensor available — up to 50 rpm
Applications
- Agriculture equipment
- Forestry equipment
- Construction equipment
- Turf care equipment
- Industrial equipment
