Fuel Oil Lubrication Oil Marine Gear Pump
Features NHGH series of gear pump is mainly composed of gear, shaft, pump body, pump cover, bearing sleeve, shaft end seal (special requirements, can choose magnetic drive, zero leakage structure). The gear is made of double arc sine curve tooth shape. Compared with involute gear, the most prominent advantage of it is that there is no relative sliding of tooth profile during gear meshing, so the tooth surface has no wear, smooth operation, no trapped liquid phenomenon, low noise, long li...

Fuel Oil Lubrication Oil Marine Gear Pump
Features NHG Serial Gear pump is a kind of positive displacement pump, that to transfer liquid by changing of working volume between the pump casing and meshing gears. Two enclosed chambers are formed by two gears, pump casing and front and rear covers. When the gears rotate, the chamber volume on the gear engaged side increases from small to large, forming a vacuum and sucking the liquid, and the chamber volume on the gear meshed side decreases from large to small, squeezing the liquid ...
