Working Principle
The BF110M series adopts an external gear meshing mechanism, consisting of a driving gear and a driven gear enclosed in a precision-machined housing. When the driving gear is activated by a prime mover, it drives the driven gear to rotate in the opposite direction. The meshing and disengagement of the gears create periodic volume changes in the enclosed chambers:
-
During disengagement, the volume of the suction chamber increases, forming a vacuum that draws fluid into the pump through the inlet.
-
As the gears rotate, the fluid is trapped in the tooth grooves and transported along the inner wall of the housing to the discharge chamber.
-
During meshing, the volume of the discharge chamber decreases, compressing the fluid and pushing it out through the outlet to provide continuous fluid power.
The pump features a built-in adjustable pressure relief valve, which allows regulating the operating pressure up to 8 bar and prevents overpressure damage to the system.
Key Features
-
Bidirectional Operation: Reversible flow direction by changing the gear rotation direction, offering flexible adaptation to diverse hydraulic system requirements.
-
Compact & Durable Construction: Cast iron housing (GG-25) and heat-treated steel gears ensure high structural strength and resistance to wear, extending service life in harsh conditions.
-
Low Noise Performance: Precision helical gears reduce pressure pulsation and operational noise, ensuring quiet running even at full load.
-
Self-Priming Capability: Can aspirate fluid from a low level without pre-filling, with a maximum suction height of 5 m, simplifying installation and operation.
-
Efficient Sealing: Equipped with NBR lip seals complying with DIN 6370 standard, preventing fluid leakage and ensuring reliable sealing performance.
Applications
The BF110M series gear pump is widely used across multiple industries due to its versatility and reliability, including:
-
Construction machinery (hydraulic systems for excavators, loaders, and cranes)
-
Agricultural equipment (tractors, harvesters, and irrigation systems)
-
Industrial hydraulic stations and lubrication systems
-
Fuel oil transfer systems (compatible with diesel, heating oil, and other lubricating fuels)
-
Mobile hydraulic systems and power units
Installation & Maintenance Notes
-
The suction pipeline should be gradually elevated to the pump inlet flange to avoid air pockets and ensure smooth fluid intake.
-
Use elastic couplings for motor connection to reduce vibration and ensure precise alignment.
-
Regularly inspect the mechanical seal and replace it if leakage occurs to maintain pump efficiency.
-
Avoid pumping corrosive, volatile, or low-flashpoint fluids (e.g., gasoline, benzene) to prevent equipment damage and safety hazards.
