Product Details

The electric hydraulic oil pump consists of plunger pump, control valve, cabinet, and internal pipes.

Composition of electric hydraulic oil pump

Pressure gauge: Made of 304 stainless steel and filled with silicone oil, it has the characteristics of shock resistance, high precision, good stability and long service life.


Control valve: Assembled on the electric oil pump, it is used to adjust the flow and pressure value of hydraulic oil to facilitate the operation of the equipment.


Fuel tank: The electric hydraulic oil pump box is welded by thin steel plates, and the surface is painted (color can be customized) to prevent corrosion.


Plunger pump: The pump is a self-priming axial plunger pump. The motor drives the shaft, and the plunger is pressed into the plunger sleeve through the swash plate on the shaft, and the return spring lifts the plunger to achieve the reciprocating motion of the plunger to achieve the purpose of oil suction and discharge.


Wheel: The front wheel is a fixed wheel, the rear wheel is a steering wheel, and the front and rear are coordinated with each other; it is made of engineering plastic, durable, wear-resistant, not cracked, and not deformed.

Electric Hydraulic Oil Pump Design Features

The electric hydraulic oil pump provides hydraulic power source for various tonnage jacks, piers, embossing machines and other equipment. According to the operation mode and flow rate of the oil pump, it can be divided into various models and specifications. At present, the main types of the company's oil pump products are ZB2-500H, ZB4-500, ZB4-600, ZB10-800H. ZB series electric hydraulic oil pump adopts the design of sealed oil tank and manual rotary valve, which has the characteristics of simple operation and good waterproof and dustproof performance; except for small electric hydraulic oil pumps, other types of electric hydraulic oil pumps are equipped with rubber wheels on the lower side of the oil tank, and on the right side There is a swivel lever for easy movement. When the electric hydraulic oil pump moves on the rough construction site, it can absorb the energy generated by the vibration and buffer the oil pump body, thereby protecting the device from damage and prolonging the service life of the device.

Electric hydraulic oil pump design features

In the case of equipped with a variety of special machines, it can realize lifting, bending, straightening, extrusion, scissors, riveting, disassembly, press-assembly and other work requirements as hydraulic power parts, but also can be installed in other mechanical equipment. It has the characteristics of small volume, light weight, simple structure, convenient operation and high working pressure.

About Us

Liuzhou Lingqiao Prestressed Machinery Co.,Ltd. is a high-tech enterprise which is concerned with the design, research, development and production of prestressing force products, established in 2011. Over the years, the company has continuously increased investment in research and development, improved the brand, research and development, design, processing, and sales of one-stop industries and services, and steadily entered the core field of prestressing industry. Products are exported to dozens of countries and regions in America, Europe, Africa, Southeast Asia, etc., and have contributed to the successful construction of key projects in many countries. The rated pressure of the electric hydraulic oil pump produced by our company is between 50~80MPa, high pressure and stability. It is the lightest tension electric hydraulic oil pump at present. The electric hydraulic oil pump is widely used in highways, bridges, high-rise buildings and other projects. Various specifications and models are available for customers to choose from.


Product Quality Control

In order to ensure the construction quality and test accuracy, the pressure gauge will be tested according to the regulations. In addition, our electric hydraulic oil pumps will undergo performance tests such as no-load performance, full-load performance, and overload performance, and can only leave the factory after passing the test.


How to use the electric hydraulic oil pump?

1. Before operation,air exists in each oil container, please open the control valve, idle the oil pump, expel the air till bubbles in oil-return hose vanish.

2. Seal the output nozzle, open the throttle valve, close the unload valve. Then switch the pump, close the throttle valve and read the pressure meter as adjust the unload valve till designed pressure. The adjusting pressure of relief valve is 10%-15% higher than working pressure.


What should be paid attention to before using the electric hydraulic oil pump?

1. The device should be wired up by professional electrician, neutral line must be connected and the insulation has to be checked.

2. The oil pipe and parts cannot be disassembled when the oil pump is under pressure.

3. In the situation of new pump, changing the oil and reusing long-spare pump, idle the pump to expel air before operating.

4. The height of oil in the cylinder mustn’t be lower than 150mm, which is able to prevent improper greasing and failure of oil absorbing in the pump.

5. Working directions of the motor is optional. Alternating forward direction with reverse direction is suggested.
