Gear pumps are a type of positive displacement pump that are appropriate for pumping relatively high pressures and low capacities. Advantages include the ability to handle a wide range of viscosity,
less sensitivity to cavitation (than centrifugal style pumps), relatively simple to maintain and rebuild. Disadvantages can include a limited array of materials of construction due to tight tolerances required,
high shear placed on the liquid, and the fluid must be free of abrasives. Also note that gear pumps must be controlled via the motor speed. Throttling the discharge is not an acceptable means of control .

A major difference between lobe and gear pumps is that the rotors are designed to remain in close contact throughout rotation. By close contact, I mean that the lobes rotate about one another at extremely close tolerances. Also, unlike the gear pump, the rotors of the lobe pump do not mesh
A gear pump is taken into utilization for meshing of gears to pump fluid by displacement. Being the most common types of pumps for hydraulic fluid power applications, these advanced pumps are used in chemical installations to pump high viscosity fluids.Among some of the top Gear Pump Supplier, name of Terrekosen-Hydraulic comes on the top. A team of dedicated professionals has been working here, who have proven track record and years of experience.
Because the speed is decreased less from an equal gear ratio.
Instead of hydraulic pumps, hydraulic gear motor does not work. Hydraulic pump hydraulic motor blade is used instead.
The oil pump is driven by the distributor drive gear on a V8.The oil pump is driven by the distributor drive gear on a V8.
Fixed
both gear pump and reciprocating pumps are positive displacement pumps.but the different is gear pump rotary type.reciprocating pump moves liner motion.the piston moves up and down in straight line.

The oil pump is located inside the oil pan, underneath the engine. The pump is driven by a gear unit that spins with the camshaft (located higher up in the engine). As the camshaft spins, it has a gear that interacts with the gear unit for the pump which spins a shaft down to the pump to pump oil. Taking off the oil pan will expose the oil pump.
A gear pump uses the meshing of gears to pump fluid by displacement.[1] They are one of the most common types of pumps for hydraulic fluid power applications. Gear pumps are also widely used in chemical installations to pump fluid with a certain viscosity. There are two main variations; external gear pumps which use two external spur gears, and internal gear pumps which use an external and an internal spur gear. Gear pumps are positive displacement (or fixed displacement), meaning they pump a constant amount of fluid for each revolution. Some gear pumps are designed to function as either amotor or a pump.
we can pump water in high current
Because the water pump on the duramax is gear driven,when you install a new water pump that meshes with an exisiting drive gear you get a noise coming from that area. The new gear on the water pump will have to wear into the existing drive gear. It would be the same if you installed a new ring gear in a differential but left the old pinion gear,you would have a similar noise. It took my dealer changing a brand new pump because it made noise to figure out that the pump was fine it just needed to break in. Hope this helps.
coz it is
The high preasure goes from the pump to the gear and the return goes from the gear to the pump resirvoir.
GEAR
A gear type pump has two gears in it that pull fluid through between the teeth creating pressure as it is forced out the other side.
