With high-quality manufacturing technology and working characteristics, it has achieved the advantages of small size and light weight while possessing * performance, providing efficient and flexible power solutions for various industrial and engineering machinery applications.

##2、 Advantages of Vickers PVH plunger pump products

###（1） Flexible design

1. * * Multiple configuration options * *: Equipped with single pump and shaft drive configurations, it can adapt to the power demand architecture of different devices. Whether it is a simple single working system or a complex combination of multiple pumps, the PVH series plunger pump can easily handle it, providing the most cost-effective equipment adaptation solution.

2. * * Rich shaft extension and control methods * *: Provides various types of drive shaft extension to meet the connection needs of different prime movers. At the same time, it has diversified control methods, including remotely controllable pressure compensators, load sensing methods, pressure and torque limiter control, etc., which can be flexibly adjusted according to actual working conditions and system requirements, bringing maximum flexibility to users.

###（2） Performance

1. * * High pressure operating capability * *: The tested component design is cleverly integrated into a heavy-duty, compact housing. This design enables the pump to operate stably at a continuous operating pressure of 250 bar (3625 psi), and in load sensing systems, it can withstand operating pressures up to 280 bar (4050 psi). Such high pressure operation capability can meet the demand for higher performance levels in today's power intensive machinery, ensuring the long-term operation of equipment under high load working conditions.

2. * * Efficient and energy-saving * *: In each application scenario, various compensators are designed for high efficiency to achieve the most effective system control. This series of plunger pumps has a volumetric efficiency of over 95%, which means that more flow is effectively utilized and more input power is directly converted into useful work, rather than being consumed in the form of heat and waste. This not only improves the overall operational efficiency of the system, but also greatly reduces energy consumption, saving users operating costs.

###（3） Convenient maintenance

1. * * Critical Component Repair Kit * *: A repair kit has been specifically developed for the most critical rotating and control components. The existence of these kits greatly simplifies the maintenance process of pumps. Even in complex working environments, maintenance personnel can quickly and accurately perform component replacement and repair operations, ensuring the success of maintenance work, effectively reducing equipment downtime, and improving equipment availability.

2. * * Low noise design * *: Adopting the concept of low-noise design, the noise level generated by the pump during operation is significantly reduced. This feature makes it particularly suitable for noise sensitive industrial use scenarios, providing operators with a more comfortable working environment and reducing noise pollution to the surrounding environment, in line with modern industrial requirements for environmental protection and work environment optimization.

###（4） Long life guarantee

1. * * Heavy duty bearings and shaft extensions * *: Equipped with heavy-duty bearings and sturdy shaft extensions, it can effectively reduce internal deformation and wear. During the operation of the equipment, even under high load and long-term working conditions, it can maintain a stable operating state, providing longer service life and longest operating time, reducing the overall maintenance cost and replacement frequency of the equipment.

2. * * Reliable internal structure * *: For example, a saddle shaped inclined plate with steel backed polymer bearings reduces wear through pressure lubrication channels and further supports internal loads. The design of rigid inclined plates reduces deflection, evenly distributes bearing loads, and greatly extends the service life of key components. The design of a single control plunger reduces the force acting on the inclined plate, while ensuring pump performance, allowing for a more compact structural design of the pump body and improving space utilization efficiency.

##3、 Application Fields

###（1） Engineering machinery field

1. Earthmoving and construction machinery: Widely used in earthmoving and construction machinery such as excavators, loaders, bulldozers, cranes, etc. With its high pressure, large flow rate, and flexible control methods, it can provide stable power support for the working devices of these machines, ensuring efficient and accurate completion of excavation, loading, lifting, and other operations. For example, in large-scale construction projects, excavators need to frequently perform excavation, rotation, and unloading actions. PVH series plunger pumps can quickly respond to control commands, automatically adjust output flow and pressure according to different workloads, and ensure the efficiency and operational stability of excavators.

2. * * Road machinery * *: It also plays an important role in road machinery such as pavers and rollers. For pavers, precise material conveying and thickness control are crucial. The PVH series plunger pump can provide stable power for its hydraulic system, ensuring that materials are evenly and continuously spread on the road surface. In the roller, the reliable performance of the pump ensures that the compaction action of the roller is smooth and powerful, meeting the requirements of different road compaction degrees.

###（2） Industrial sector

1. * * Machine tool * *: In machine tool equipment, the PVH series plunger pump provides a stable power source for various machining operations. Whether it is cutting on a lathe, milling on a milling machine, or precision grinding on a grinder, a hydraulic system is required to accurately control the movement of the worktable, tool feed, and spindle rotation. The PVH series plunger pump, with its high-precision flow and pressure control capabilities, can meet the strict requirements of machine tools for machining accuracy and stability, ensuring the production of high-quality components.

2. * * Plastic Machinery * *: In plastic machinery such as injection molding machines and extruders, this series of plunger pumps can provide the required high-pressure, high flow hydraulic power for injection molding, plastic extrusion and other processes. By precisely controlling the pressure and flow rate of the hydraulic system, precise injection and extrusion of plastic melt can be achieved, ensuring the molding quality and production efficiency of plastic products. For example, in the production of large plastic pipes, the extruder needs to continuously and stably output high-pressure melt, and the PVH series plunger pump can operate stably to meet this process requirement, ensuring the quality of the pipes and the continuity of production.
