1. What is a hydraulic pump? (Hydraulic Pumps)

In today’s industrial production, hydraulics and hydraulic systems are extremely important. It helps the automation production process to be improved and developed, productivity to increase and work efficiency to increase.

In the hydraulic system, we cannot help but mention the hydraulic pump, a central device of the hydraulic system. The hydraulic system includes: Engine, hydraulic pump, oil source, hydraulic cylinder and hydraulic valves. So what is the hydraulic pump here? Let’s find out with us.

It is considered the heart of the hydraulic system. It performs the job of sucking oil and water from the tank and pumping and pushing it at high pressure into the system of pipes to supply cylinders, filters, valves… to operate. High pressure hydraulic pumps are also quite popular on the market

Or it can be understood that a high pressure hydraulic pump converts mechanical energy into the energy of the fluid flow. The pump is where the hydraulic movement is connected through hydraulic valves and connections.

Normally, pumps have a variety of working pressure levels, which can be set at 700 bar or high-pressure hydraulic pumps can reach 10,000 Psi. Depending on the system, a system can install 1 or more pumps to serve the job.

2. Hydraulic pump specifications 

In general, hydraulic pumps often have a variety of working pressure levels and technical parameters often fluctuate:

• The pressure on the hydraulic pump can be from 700 bar to 10,000 Psi depending on the type of pump, so it will be installed at locations on the oil tank.
• Max Pressure: 250kg/cm2
• Rated pressure: 210 kg/ cm2
• Speed: 500- 3000
• Pump stage: 1-3
• Pump speed: 3000 rpm

3. Principle of operation of hydraulic pumps in hydraulic systems

All hydraulic systems as well as hydraulic pumps operate according to a certain principle.

The hydraulic pump will create a flow inside the hydraulic fluid pipe at a high pressure, strong enough to overcome the resisting pressure of the load. High pressure hydraulic pump is a mechanical device that converts mechanical energy into hydraulic energy.

During its operation, the pump will perform the following two functions:

• First, the gas pressure in the pump will cause oil, lubricant, and liquid from the tank to flow into the pump.
• Next, this oil, lubricant or liquid will be introduced into the pump pipeline under the influence of mechanical force and then it will create a thrust to push it into the system.

Pump capacity will be easily determined through the parameters of: operating pressure, flow and flow provided by the hydraulic pump. High pressure hydraulic pumps can withstand large operating pressures and flows.

4. Types of hydraulic pumps

4.1 Manual hydraulic pump

Manual hydraulic pumps have oil suction and push operations that depend on the mechanical force of the human hand. Because of its small capacity, it is very suitable for small production needs and human life. Manual hydraulic pump manufacturers will have different models but generally still operate according to the same principle.

There are two types of manual hydraulic pumps: 1-way and 2-way pumps.

Manual hydraulic pumps will promote their role and effectiveness when combined with other equipment and tools, specifically:

• Combined with a hydraulic jack: A manual hydraulic pump will make the work easier and not require too much effort to lift large objects. Depending on the capacity of the jack, the user will choose a manual hydraulic pump with appropriate parameters.
• Combined with cos press heads: People also use hydraulic pumps for cos press heads. Helps the working process take place quickly, with high accuracy and decisiveness.

• Combined with a busbar bending machine: Finally, it is a manual hydraulic pump combined with a busbar bending machine in mechanical manufacturing. You can change the speed of the hand pump to suit the job.

4.2 Electric hydraulic pump

An electric hydraulic pump or electric hydraulic pump is a type of pump that uses an electric motor to pump oil into hydraulic equipment to help the measuring equipment operate. This type has the same operating mechanism as a manual hydraulic pump, but because it uses an electric motor to operate, it consumes less time and labor than a manual hydraulic pump. Electric hydraulic pumps are suitable for working in locations with large spaces.

There are 2 types of electric hydraulic pumps:

• One-way electric hydraulic pump: is a powerful tool that helps create strong pressure in connection with other hydraulic tools. The return process of the cylinder is automated because the pump has an integrated discharge valve. A hydraulic pump using 1-way electricity will be simpler in structure and easier to use than a hydraulic pump using 2-way electricity. Therefore, pump maintenance will be easier.
• 2-way electric hydraulic pump: For 2-way electric hydraulic pump, this line has a slightly more complicated structure. The difference is due to the use of two pipes connected to the hydraulic system. Thanks to this design, machine operation time is shortened and helps work take place simultaneously quickly and cost-effectively.

5. Genuine high pressure hydraulic pump price

Currently, on the market there are many different types of hydraulic pumps, manual hydraulic pumps, electric hydraulic pumps or high-pressure hydraulic pumps with diverse designs and prices ranging from a few million to a few dozen. million dong.

In addition to choosing a famous manufacturer, you also need to look for a supplier of quality, reputable, and famous hydraulic pumps and other spare parts in the market. However, the price of the pump also depends on the manufacturer, model, pump capacity, etc.
