U30 12+4.5cc Hydraulic Gear Pump For Kubota U30
Excavator Spare Parts U30 12+4.5cc Hydraulic Gear Pump for Kubota U30
Products Description
The U30 12+4.5CC is a precision-engineered dual-displacement hydraulic gear pump, featuring switchable displacement of 12CC and 4.5CC to adapt to variable load demands in industrial systems. As a positive displacement type, it relies on intermeshing gears to create low-pressure suction and high-pressure discharge, delivering stable fluid transfer for medium-light duty applications .
Manufactured with industry-standard materials and craftsmanship, this pump excels in self-priming capability, resistance to oil contamination, and wide speed adaptability . It is widely used in agricultural machinery, small construction equipment, and industrial hydraulic systems, balancing efficiency and cost-effectiveness for both OEM and replacement markets.
