With advantages of on-load startup,overload protection,torsional vibration isolation,impact mitigation,stepless speed regulation

YOTFJ450/560/650/750/875 speed-adjustable hydraulic coupling reverse-gear reducer

Product usage: used together with 140, 190, 260, 320 and other series diesel engines manufactured by us and Caterpillar, Volvo and Cummins diesel engines or electric motors for driving mud pumps.

Features: the product features the combination of fixed tubes for oil drain and imported valve control and regulation to realize the adjustment of speed. With advantages of on-load startup, overload protection, torsional vibration isolation, impact mitigation, stepless speed regulation, quick and steady clutch, etc, the product is the best variable speed drive for mud pump.

Technical data:

Input speed: 1000~1500 r/min

Transmission power: 200~3000 kW

Rated efficiency: ≥96%

Gear reduction ratio: 2.0~3.3 (depending on the equipments used by the customer)

Rated slip: 3%

Adjustable speed range: 1~1/3

Clutch sensitivity: 6~8S

This series of products are newly developed hydraulic coupling reducers designed for solid control circulating system of the drilling mud pump. The product features the adoption of fixed-tube speed regulation technology to realize the stepless speed regulation, quick and steady clutch of the coupling, and is the best choice for the oil drilling mud pump in China currently.
