4 Design Features That Determine Hydraulic Gear Pump Selection

One of the most commonly used hydraulic structures in equipment operating with hydraulic systems is the hydraulic gear pump. The lower number of moving parts in these pumps makes maintenance easier compared to other pumps. Their tolerance to dust and contamination and their lower cost are also among the factors influencing their preference. Additionally, the simple structure of gear pumps and their high suction heights and efficiencies make these pumps advantageous.

What are the applications of hydraulic gear pumps?

Various design principles and configurations are applied during the production of hydraulic gear pumps. Hydraulic gear pumps can be used in a wide range of projects and industries where different requirements such as lifting, lowering, opening, closing, or rotating are expected, and safety and durability are essential.

How is the selection of hydraulic gear pumps made?

Many criteria must be taken into account when selecting a hydraulic gear pump. The selection of different types of hydraulic gear pumps produced according to working conditions and the needs of the job should also consider the manufacturer's recommendations. Some of the factors that should be considered when selecting a hydraulic gear pump are as follows:

·         Desired pressure range

·         Desired speed

·         Operating temperatures

·         Expected noise level

·         Control type

·         Maintenance possibilities

·         Cost

·         Sensitivity to oil contamination

Selection of Hydraulic Gear Pumps According to Applications

1. Body Type

Hydraulic gear pumps are generally produced with aluminum and cast iron bodies.

  • Aluminum Body Gear Pumps

These are gear pumps with aluminum bodies. Thanks to their long-lasting and durable performance even in wide temperature and pressure conditions, they are widely used in various industrial and agricultural applications. They have robust and reliable features, making them suitable for a wide range of applications.

  • Cast Iron Body Gear Pumps

These are gear pumps with cast iron bodies. Cast iron body gear pumps are designed for heavier pressure conditions. They work with superior performance and efficiency under high operating pressures. They are used in mobile and industrial fields, especially in heavy-duty applications such as material handling and construction machinery.

2.  Displacement

Hydraulic gear pumps can be divided into different groups according to their displacement. The oil capacity delivered by these pumps at each rotation is an important factor in determining the selection. Displacement should be determined according to the project to be used. Large projects require high displacement.

3. Shaft Type

The shaft type differs according to the usage area of the hydraulic gear pump. Considering the needs of the machine, shaft selection should be made outside the standard, if necessary. Different types of shafts can be combined with different types of caps for special situations.

4. Body Hole Type (Connection Type)

Another factor affecting the design of the pump is the body hole type. It helps the movement of the systems by allowing the hydraulic oil to be sucked in with low pressure and released with high pressure. Body hole types vary depending on usage area and desired pressure amount.
