It supports multiple control forms.
It is applicable to all types of coaxial structures.
The shaft ends can be equipped with SAE spline structures or SAE/metric flat keys as options.
I. Product Overview
The PVP series hydraulic plunger pumps are swashplate-type axial piston pumps specifically designed for open-circuit applications. With their high-precision structural design and optimizable performance parameters, these pumps are widely utilized across various industries, including construction machinery, mining machinery, industrial hydraulic stations, steel industry, marine industry, petrochemical industry, and agricultural machinery.
II. Product Features
1. Through-Shaft Structure Design
• The PVP series plunger pumps feature a through-shaft structure, enabling them to function as both single pumps and multi-unit combined pumps. This design supports more complex hydraulic configurations to meet diverse operational requirements.
2. Multiple Displacement Options
• The series offers a range of displacement options, from 16 to 140 ml/rev, allowing for flexible adjustments based on actual needs to cater to various application scenarios.
3. High Pressure and High Speed
• These pumps can operate stably under pressures up to 250 bar and speeds up to 500 rpm, fully meeting the demands of high-efficiency operations.
4. High-Quality Materials and High Strength
• The pump body is constructed from high-strength cast steel, providing excellent durability and strength. This not only extends the equipment's service life but also effectively resists the impact of high-pressure fluids, reducing vibration and noise during operation.
5. Low-Noise Operation
• Through optimized design and the use of high-quality materials, the PVP series plunger pumps generate minimal noise during operation, improving the working environment.
6. Flexible Installation Options
• The pumps support both metric and SAE installation standards, with shaft ends available in SAE spline and metric or SAE flat key configurations, accommodating various working conditions. Additionally, SAE flange oil ports are provided on the pump body's side, enhancing installation and maintenance convenience.
7. Multiple Control Forms
• The PVP series plunger pumps offer various control forms, such as standard pressure regulators and remote pressure regulators, enabling precise control based on system requirements.
8. High Safety and Reliability
• Equipped with an integrated overload protection device, the pumps automatically relieve pressure when the system pressure exceeds the set value, preventing pump damage due to overpressure and significantly enhancing equipment safety and service life.
III. Product Applications
1. Steel Industry
• In steel production processes, various hydraulic equipment is essential. The PVP series plunger pumps are widely used in hydraulic systems such as tilting devices for steel smelting furnaces and drive systems for rolling mills, thanks to their efficient, stable, and reliable performance.
2. Marine Industry
• Marine hydraulic systems have extremely high performance requirements, especially in complex and harsh environments. The PVP series plunger pumps are extensively applied in critical components such as steering gear systems and deck machinery on ships, owing to their outstanding durability and reliability.
3. Mining Machinery
• In mining operations, hydraulic excavators, mining transport vehicles, and other equipment require robust power support. The PVP series plunger pumps play a central role in the hydraulic systems of these machines, ensuring stable operation and efficient performance.
4. Petrochemical Industry
• In the petroleum and chemical sectors, various pressure vessels and reactors require precise pressure control and flow regulation. The PVP series plunger pumps are widely used in the hydraulic systems of these devices due to their precise control capabilities and long service life.
5. Agricultural Machinery
• In agricultural machinery such as tractors and harvesters, hydraulic systems are crucial for efficient operations. The PVP series plunger pumps are also widely applied in the hydraulic systems of these machines due to their excellent durability and reliability.
IV. Product Maintenance and Care
1. Regular Inspection and Replacement of Hydraulic Oil
• Regularly inspect the quality and level of hydraulic oil to ensure it is clean and sufficient. Replace or replenish the hydraulic oil as necessary to prevent failures caused by oil contamination or insufficient oil levels.
2. Cleaning of Suction Filter Elements
• Regularly clean the suction filter elements (recommended every 200 hours) to prevent impurities from entering the pump body and causing wear or malfunctions.
3. Inspection of Port Plate Wear
• Periodically inspect the wear condition of the port plate and replace or repair it as necessary to ensure the pump's normal operation.
4. Attention to Operating Environment
• Avoid operating the pump in harsh environments such as high temperatures, humidity, or corrosive gases to extend its service life.
