Gear pumps

Gear pumps

The gear pump is used in a variety of hydraulic systems due to its simple design, significant service life and low cost. The gear pump is capable of supplying the working liquids up to 300 l/min, and work at pressures up to 250 bar.

The popularity of this type of pump has led to the fact that there are a lot of fakes on the market, so if you want to buy the gear pump is really high quality, get it from a reliable supplier. Company "Motorimpex" is the official representative of European brands of hydraulic equipment, all presented the products are certified on the site.

Gear pumps: classification

The first sign by which the gear pumps can be grouped is the displacement and productivity. Entry into a particular group depends on the specific manufacturer. At the moment, there are 5 groups:

• group 0: working volume - 0.25-2.3 cm³;
• group 1: working volume - 1-9.8 cm³;
• group 2: working volume - 4.5-36 cm³;
• group 3: working volume - 20-87 cm³;
• group 4: working volume - 60-150 cm³.

Hydraulic pumps of one group have the same connection dimensions, types of shafts and flanges. Thanks to this allows interchange of pumps from different manufacturers.

Another important classification feature by which one can distinguish gear hydraulic pumps is the principle of operation. There are two groups:

• internal gear pumps: the operation is based on the rotation of the auxiliary gear, which presses against the rotor teeth (main gear). The working fluid is pushed out through the crescent-shaped element;
• external gear pumps: work is done by a pair of equivalent gears. Liquid is pushed between their teeth around the perimeter of the pump chamber.

Hydraulic gear pumps: advantages

The NSh hydraulic pump has a rather large list of advantages in comparison with other types of pumps. Here are just some of them:

• high efficiency;
• smooth flow without pulsation at the outlet;
• the possibility of sectional execution;
• simplicity and low cost of maintenance;
• work with viscous and abrasive liquids.
