Structural Features
-
Robust Construction: The M execution adopts special aluminum alloy housing for lightweight and corrosion resistance, while the МЧ execution uses high-strength cast iron housing to withstand higher pressure and ensure long-term durability . Both versions feature a compact design, small volume, and light weight .
-
Reliable Connection: Equipped with B-type square flange and involute spline shaft, ensuring stable power transmission and easy integration into hydraulic systems .
-
Working Principle: As an external gear pump, it forms a sealed working volume with meshing gears, pump body, and side covers . When the gears rotate, the volume of the suction chamber expands to draw oil, and the volume of the discharge chamber contracts to deliver oil, realizing efficient fluid transfer .
-
Low Maintenance: Simple structure, easy manufacturing, and insensitivity to oil contamination reduce maintenance costs and improve operational reliability . Spare parts are easily accessible, further lowering service expenses .
Application Scenarios
-
Agricultural machinery: MTZ tractors, combines, and other agricultural vehicles.
-
Construction machinery: Bulldozers, graders, wheel loaders, and backhoe loaders.
-
Material handling equipment: Forklifts and other loading/unloading machinery.
-
Other equipment: Municipal devices, logging machinery, and stationary hydraulic systems driven by electric motors.
