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 ...

Self-priming Inline Vertical Centrifugal Ballas...
Maine Features The EMC-type is solid casing type and is fitted to motor shaft rigidly. This series can be used for Line pump because the center of gravity and height is low and suction inlet and discharge out let of the both sides are in a straight line. The pump can be used as an automatic self-priming pump by fitting an air ejector. Performance * Handling fresh water or sea water. * maximum capacity: 400 m3/h * maximum head: 100 m * Temperature range -15 -40oC Application Des...
