A hydraulic gear pump is a type of hydraulic pump that uses a gear system. It could be found in many applications of hydraulic systems. It consists of few moving parts, works quite smoothly and operates well at high pressure up to 250 bars. The displacement chambers are formed between the housing of the pump and the rotating gear wheel (or gear wheels, according to the model).
We review following two gear pumps, which we think as the best as they have excellent customer ratings.
Hydraulic Gear Pump – 16 GPM, 2-Stage (Brand New)
First pump is the moderately priced Hydraulic Gear Pump – 16 GPM, 2-Stage (Brand New) from Mighty. This 2 stage gear pump weighs 6.3 pounds. It is particularly convenient to be used in log splitters, power units for snow ploughs, press & machine tools, which are with small displacement and moderate pressure hydraulic systems. It rotates in a clockwise direction and provides faster cycle times and higher possible pressure with a small engine. They could be effectively used in low-pressure hydraulic systems.
The unit is made out of cast iron and aluminium. This pump has a rated maximum operation speed of 3600RPM and maximum operation Pressure of 3000PSI. The shaft extension is 1.5”, and Shaft Diameter is 1.5”.
The pump has an impressive 4.4 out of 5 stars rating on Amazon, as most of the users were satisfied with it. Customers consistently said that the gear pump did exactly what was promised to deliver.
Concentric High Pressure Hydraulic Gear Pump – 0.065 Cu. In., Model# G1204C5A300N00
The best gear pump that tops our list is the Concentric High-Pressure Hydraulic Gear Pump – 0.065 Cu. In., Model# G1204C5A300N00 from Haldex. It is slightly more expensive than the Hydraulic Gear Pump – 16 GPM, 2-Stage (Brand New) from Mighty.
The unit weighs only 5 pounds. It is with a maximum rated operating pressure of 3000 PSI together with a maximum rated RPM of 4000. This pump is able to turn in both clockwise and counter clockwise directions. This Concentric High-Pressure Hydraulic Gear Pump can be used on mobile equipment such as construction and agricultural equipment, material handling and mining equipment, machine tools, PTO pumps, compaction and baling equipment and refuse haulers. It can be used as a fluid pump of a fluid motor.
This gear pump is made of heavy-duty cast iron. It is with a standard 4-bolt mount with 1.78” diameter pilot and a shaft with dimensions of 0.5” x 1.5”. The square key is 0.12”. The hydraulic gear pump has belt (pulley) and drive flexible coupling. It is rated at 90 % efficiency.
This tool has an excellent 5 out of 5 stars rating on Amazon.
You were given details of two leading hydraulic gear pumps available in the market. Gear pumps could be used in wide range of applications in hydraulic systems. However, you will need different types of gear pumps for different applications. The Hydraulic Gear Pump – 16 GPM, 2-Stage (Brand New) is used in modest pressure pumps that are used in press & machine tools, log splitting, and power units for snow ploughs. The Concentric High-Pressure Hydraulic Gear Pump – 0.065 Cu. In., Model# G1204C5A300N00, can be effectively used in high pressure applications such as mining and PTO pumps.
