Product categories of ultra-high pressure electric pumps

There are many hydraulic products, and ultra-high pressure electric pumps are a type of hydraulic product. This type of hydraulic product is driven by an engine or electric motor, and then draws oil from the hydraulic oil tank to form a pressure oil discharge.

So what are the common types of ultra-high pressure electric pumps? Let's take a look below.

(1) According to whether the flow rate is adjustable, it can be divided into variable displacement pumps and quantitative pumps.

The output flow rate that can be adjusted according to needs is called a variable displacement pump, while the flow rate that cannot be adjusted is called a fixed displacement pump.

(2) According to the commonly used pump structures in hydraulic systems, there are three types: gear pumps, vane pumps, and plunger pumps.

Gear pump: smaller in size, simpler in structure, less strict in oil cleanliness requirements, and cheaper in price; But the pump shaft is subjected to unbalanced force, severe wear, and significant leakage.

Vane pump: divided into double acting vane pump and single acting vane pump. This type of pump has uniform flow rate, smooth operation, low noise, higher operating pressure and volumetric efficiency than gear pumps, and a more complex structure than gear pumps.

Plunger pump: High volumetric efficiency, small leakage, capable of working under high pressure, mostly used in high-power hydraulic systems; But the structure is complex, with high requirements for materials and processing accuracy, expensive prices, and high requirements for oil cleanliness.

[Note: Generally, plunger pumps are only used when gear pumps and vane pumps cannot meet the requirements. There are also some other forms of hydraulic pumps, such as screw pumps, but their applications are not as common as the above three types]

That's all for the introduction of the common types of ultra-high pressure electric pumps and their related characteristics above. If you need an ultra-high pressure electric pump, you can contact us for consultation!
