Gear Pumps - (543 companies)...teeth. As the gears come out of mesh on the inlet side, liquid is drawn into the pump. The liquid is forced out the discharge port by the meshing of the gears. Some contain a crescent shaped partition used to separate the inlet volume from... -
Gears - (695 companies)Gears are rotating mechanical devices employing 'teeth' in order to transmit torque between separate axes. Two or more cooperating gears are called a transmission and can produce a mechanical advantage by changing speed, torque or rotation direction... -
Metric Gears - (76 companies)Metric gears are defined by module, which designates the center-to-center distance between successive teeth. This criteria of gear selection is used in countries which have adopted the metric system and is intended to standardize gear selection... -
Hydraulic Pumps - (689 companies)Hydraulic pumps deliver high-pressure fluid flow to the pump outlet. Hydraulic pumps are powered by mechanical energy sources to pressurize fluid. Hydraulic pumps are positive displacement pumps which pressurize hydraulic fluid in order to do work... -
Spur Gears - (255 companies)Spur gears are the simplest type of gear. Transmitting power between parallel axes, the teeth project radially on the disc. Spur gears are simple, easily manufactured gears and are usually the first choice when exploring gear options. Transmitting... -

jbj Techniques Limited
Bearing supported hydraulic gear pumps & motors Bearing supported gear pumps and gear motors, ideal where pumps are driven by a drive shaft or driving equipment by pulley and drive belt. Agricultural machinery is an obvious example. A motor with a bearing support is useful for a fan drive or again if a pulley is fitted for belt drive. Any application that induces side load on the output shaft, a bearing support built into the gear pump or gear motor is beneficial, if not, necessary. Group 2, hydraulic gear pumps and motors with bearing... (read more)Browse Gear Pumps Datasheets for jbj Techniques Limited -

Low noise, high efficiency helical gear pumps Reduce noise levels by an average of 15 dBA. Up to 20 dBA depending on pump size. The helical profile of the gears within the ELIKA (R) hydraulic gear pump, reduces pressure oscillations and vibrations produced by the pump, subsequently transmitted to the other components. Less pressure oscillations and vibrations reduces the noise of the hydraulic system. Axial forces induced by the helical gear teeth are optimally balanced in all operating conditions by the axial compensation system...
