BM1 Series Orbital Hydraulic Motor
Key words:
Classification:
Description
BM1 series orbital hydraulic motor is a kind of shaft distribution hydraulic motor. The series motor uses a column-mounted rotating stator pair, which has a structure that works under high pressure and can automatically compensate, so that the whole machine has high efficiency and good retention. Long working life. Its characteristics:
• The use of advanced stator parameters design, low starting pressure, high efficiency, and good retention, smooth operation.
• The use of high-pressure shaft seal, can carry high back pressure, allowing series, parallel use.
• Special design of linkage shaft structure, long service life of motor.
• Special flow distribution system parameter design to meet low noise requirements.
• The motor is compact and easy to install.
