Product Description

The IPVP series gear pump is a kind of positive displacement pump with advanced technology and reliable performance. Here is a detailed English introduction:
 
Features and Advantages
- High Efficiency: Thanks to its advanced design and high - quality materials, the IPVP series gear pump has a positive displacement design that ensures a constant flow rate even at varying pressures, with high volumetric efficiency, averaging up to 96%.
- Precise Control: The internal gear design of the pump ensures precise control of the output. Its compact size and lightweight design make it easy to install and adapt to various fluid types and flow rates.
- High - Pressure Resistance: It can withstand high pressures, with continuous operating pressures ranging from 210 bar to 330 bar and peak pressures ranging from 250 bar to 345 bar (at 1500 rpm).
 
Structure and Principle
The IPVP gear pump adopts an internal gear structure. When the gears rotate inside the pump, the pressurized fluid is drawn into the cavity between the pinion and internal gear. In the radial direction, the gear chambers are closed by gear meshing and the filler piece. In the axial direction, the axial plates seal the pressure chamber with the minimal possible gap, which minimizes volume losses and increases efficiency.
 
Model Specifications 
The IPVP series has a variety of models, such as IPVP 3 - 3.5, IPVP 3 - 5, IPVP 4 - 13, IPVP 5 - 32, etc. The displacement ranges from 3.6 cc/rev to 251.7 cc/rev, the minimum speed is 400 rpm, and the maximum speed varies from 1800 rpm to 3600 rpm depending on the model.
 
Application Areas
The IPVP gear pump has a wide range of applications, including machine tools, plastics machinery, mobile hydraulic systems, metal plate processing equipment, presses, transmission and lifting equipment, shipbuilding, municipal vehicles, power plants, and special equipment manufacturing. Here is a detailed introduction:
- Plastic machinery: Such as injection molding machines, foaming machines, etc. The gear pump provides a high-pressure oil source for them, driving actions like mold clamping and injection, ensuring the stability of molding. For example, in the injection molding process, precise pressure control can guarantee the dimensional accuracy and appearance quality of plastic products.
- Metal plate processing equipment: It is mainly used in high-pressure CNC bending machines and other equipment. The stable pressure output of the gear pump can ensure the accuracy and quality of plate bending, and its low-pulse characteristic can reduce equipment wear and prolong the service life of the equipment.
- Machine tool field: In the hydraulic station of machine tools, the IPVP gear pump is used to control auxiliary actions such as tool magazine tool change and guide rail clamping, ensuring the continuous and efficient progress of the processing process. Its high volumetric efficiency and low noise characteristics also meet the requirements of precision machining of machine tools.
- Construction machinery: It can supply oil to the travel motors of construction machinery such as excavators and cranes, and can withstand vibration and temperature difference fluctuations in the field, providing power support for the stable operation of construction machinery under complex working conditions.
- Shipbuilding industry: Many hydraulic systems on ships require reliable power sources. The IPVP gear pump is widely used in hydraulic deck machinery, steering gear systems of ships due to its high pressure resistance, low noise and stable performance.
- Energy field: In the wind power pitch system, the gear pump provides hydraulic power for the pitch mechanism, ensuring that the blades can accurately adjust the angle according to the change of wind speed, improving the efficiency of wind power generation. In addition, it is also used in the power unit of petroleum machinery to provide power for various hydraulic equipment in the process of oil exploitation and transportation.
- Environmental protection equipment: Due to its low noise characteristic, the IPVP gear pump is suitable for noise-sensitive environmental protection equipment, such as garbage collection vehicles, which can reduce the noise pollution of equipment operation to the surrounding environment.
- Centralized lubrication system: The gear pump can be used to deliver high-viscosity grease to bearings, guide rails and other parts, realizing automatic lubrication of equipment, reducing the frequency of manual maintenance, and improving the reliability and service life of the equipment.
