The YOTFJ750 speed-adjustable hydraulic coupling reducer is designed for use with 140, 190, 260, and 320 series diesel engines and electric motors. It is primarily used for driving drilling mud pumps.
The hydraulic coupling combines fixed-tube oil drainage technology with imported valve control to achieve precise speed regulation. Key advantages include:
On-load startup capability
Overload protection
Torsional vibration isolation
Shock absorption
Stepless speed adjustment
Fast and smooth clutch engagement
Stable and reliable transmission performance
It is an ideal variable-speed drive solution for drilling mud pump applications.
