M045AW1L0M200SVFSP Hydraulic Piston Pump M5 M12 M18 M25 M41 M45 M50 M63 M80 M90 M108 M125 M160 M180

1. Technical parameters:
Displacement: Based on the characteristics of the M series, it is estimated that its displacement is approximately 45cm³/r, but the specific value should be referred to the product manual.
Pressure: Generally, the continuous working pressure of the M series plunger pump can reach around 280bar, the intermittent working pressure can reach 320bar, and the peak working pressure is 350bar. This model may fall within this range.
Flow rate: At a pressure of 210bar, the flow rate at 1800r/min is approximately 76L/min. The specific flow rate may vary depending on the rotational speed and pressure.2. Working Principle:
The M045AW1L0M200SVFSP piston pump is an axial piston pump. When the transmission shaft drives the cylinder block to rotate, the plunger moves back and forth under the action of the swash plate. When the plunger rotates with the cylinder to the low position of the swash plate, it extends outward. The volume of the sealed working chamber between the bottom of the plunger and the cylinder increases, creating a local vacuum. Under the action of atmospheric pressure, the oil in the oil tank enters the sealed working chamber through the oil suction pipe and the oil suction window on the oil distribution plate, completing the oil suction process. As the cylinder continues to rotate, the plunger moves from the low position to the highest position of the swash plate, retracts into the cylinder, and the volume of the sealed working chamber decreases. The oil inside the chamber is compressed, and the pressure rises. When the pressure exceeds the system pressure, the oil is discharged through the pressure oil window on the oil distribution plate and enters the pressure pipeline of the hydraulic system, thus achieving the oil pressure process.

3. Product Features and Advantages:
Variable regulation: It can automatically adjust the flow output according to the changes in system pressure, and can rationally utilize hydraulic oil in complex working environments, improving system efficiency.
High-pressure stability: With a relatively high rated pressure and maximum pressure, it can operate stably in high-pressure environments, ensuring the normal working condition of the system.
Compact structure: Small in size and light in weight, it has an advantage in application scenarios with limited space and can reduce the installation space requirements of the equipment.
Long service life: Utilizing high-quality materials and techniques, such as special protective shaft seals, it can effectively resist external contaminants, withstand high-pressure water flushing, and extend the service life of the pump.
Low noise: Measures to reduce noise may have been adopted in the design, resulting in lower noise during operation and providing a quieter working environment.

4. Usage functions and purposes:
As the power source of the hydraulic system, it converts mechanical energy into hydraulic energy, providing stable hydraulic power for the equipment. It is widely applied in scenarios that require high-pressure and high-flow hydraulic power, such as excavators and cranes in construction machinery, harvesters and tractors in agricultural machinery, as well as related equipment in fields like shipbuilding and aerospace.

5. Applicable machines and scenarios:
It is applicable to various mechanical equipment with high requirements for hydraulic systems, such as concrete pump trucks and rollers in construction projects, rock drills and mining trucks in mining machinery, cranes and forklifts in port equipment, etc. It performs outstandingly in scenarios that require high-precision control and high-performance output, such as when excavators are in operation, it can precisely control the movement of the digging arm and provide stable and powerful power support.

6. Similar models:
Models such as M25AW2Q0M200SVN and M180AW1L0M211SVF in the M series, as well as various models of quantitative axial piston pumps in the PA/PAC/PAD series, including single-flow pumps within the range of 12-114 ml/RPM, Models of dual-flow pumps within the range of 2×25 ml to 2×75 ml per revolution, etc.

7. Precautions for Use
Oil selection: Clean petroleum-based hydraulic oil with a viscosity range of 20-400mm³/s when the applicable temperature is 0-60℃, such as hydraulic oil equivalent to ISO VG32 or 46. At the same time, it is necessary to ensure the cleanliness of the oil to avoid the mixture of impurities.
Installation requirements: An elastic coupling is required to connect the pump and the motor. The coaxiality of the two shafts should be adjusted to ±0.1mm, and the angular error should not exceed 0.5 degrees.
Pipe connection: The inner diameter of the oil drain pipe should be greater than φ12. It is necessary to ensure that the pressure inside the pump cavity is less than 0.1MPa and the impact pressure is less than 0.5MPa. The length of the pipe should be less than 1 meter. It should be installed separately and the end of the pipe should be immersed in oil. When steel pipes are used at the suction or discharge ports, rubber hoses can be used to avoid noise caused by additional loads.
Start-up and operation: Before the first start-up, clean hydraulic oil should be injected into the pump through the oil filling port. The air inside the pump and in the pipelines should be completely expelled. During operation, pay close attention to monitoring parameters such as the pump’s pressure, flow rate and temperature. If any abnormal sounds, vibrations or temperature rises are detected, stop the machine immediately for inspection.
Maintenance and care: Regularly inspect the sealing parts, bearings and other components of the pump. If any damage is found, replace them in time. Replace the lubricating oil in a timely manner according to the prescribed time intervals and lubricating oil replacement cycles, and clean the lubricating oil filter.
