Product Introduction

Atos PFED Series Hydraulic Single Reciprocating Pump Piston For Trucks

Product Overview


Designed specifically for the harsh commercial vehicle environment, this Atos PFED Series Hydraulic Single Reciprocating Pump Piston is the core power source for driving the critical hydraulic system of the truck. As the core component of the atos pfed series, its precise reciprocating pump piston design ensures high-pressure, stable and pulsation-free hydraulic oil delivery, meeting the critical application requirements of steering systems, lifting platforms, dump mechanisms, etc. Choose genuine atos pfed pump pistons to ensure the long-lasting and efficient operation of your truck's hydraulic system.

Core technologies and parameters

 

Advanced piston design: The reciprocating pump piston, manufactured with high-strength alloy materials and precise grinding processes, features outstanding wear resistance and fatigue strength, significantly extending the service life of the pump body.

The outstanding performance of the PFED series: The fluid dynamics design optimized specifically for the atos pfed series reduces internal leakage, enhances volumetric efficiency, and provides reliable flow output even under low-temperature start-up or high-load conditions.

High-efficiency and stable output: pfed pump offers a working pressure of up to [please insert the specific value here, for example: 250 bar], and a flow range coverage [please insert the specific value here, for example: 5-50 cm³/rev], ensuring that the truck's hydraulic system responds quickly and operates precisely.

Sturdy and durable structure: The atos pfed pump has a compact and sturdy overall structure. The shell is made of high-quality cast iron or aluminum alloy, which can effectively resist the vibration and shock during the operation of the truck and adapt to harsh working conditions.

Application scenarios (specifically designed for trucks

 

  • Truck hydraulic Power Steering Systems
  • Tipper Body Lifting mechanism of dump truck cargo box
  • Truck crane or truck-mounted crane hydraulic power unit (Loader Cranes/Hiab)
  • Truck tailboard lift platform (Tail Lifts)
  • Specialized Hydraulic Tools drive for special operation trucks
  • Choose genuine atos pfed reciprocating pump piston to provide continuous, powerful and reliable power for the critical hydraulic functions of your truck.

Core advantage

 

Outstanding reliability: The precise reciprocating pump piston manufacturing process and strict quality control ensure the stable operation of the atos pfed pump under the long-term and high-load operation of trucks, reducing downtime due to faults.

High efficiency and energy saving: The pfed pump's optimized design reduces internal friction losses and energy consumption, enhancing the overall fuel economy of the truck.

Easy maintenance: The atos pfed pump adopts a modular design. Key components such as pistons and seals are easy to inspect and replace, reducing maintenance costs and downtime.

Wide compatibility: Specifically designed to match mainstream truck hydraulic systems, ensuring easy installation and worry-free replacement.

Quality Assurance: Originating from the ATOS brand, it enjoys first-class quality assurance and comprehensive after-sales service support.

Maintenance and upkeep

 

Regularly check the cleanliness and oil level of the hydraulic oil, and use hydraulic oil of the recommended viscosity grade.

Replace the hydraulic oil and filter element according to the manufacturer 's recommended cycle to prevent contaminants from wearing down the critical reciprocating pump piston surface.

Pay attention to the noise and temperature of the pump operation. Repair it in time if any abnormal situation occurs.

It is recommended that the components of the atos pfed series be maintained with original factory spare parts to ensure the performance and lifespan of the atos pfed pump.

To protect your rights please read the following carefully Pump Start-up Procedure Preparation Prior to Start-up The reservoir and circuit should be clean and free of dirt and debris prior to filling with fluid. Circuit Cleanup The reservoir should be charged with filtered hydraulic fluid. The fluid level should be sufficient to prevent vortexing at the suction connection to the pump inlet. It is good practice to clean the system by flushing and filtering, using an external slave pump. Filling Pump and Removing Air If the pump is mounted above the fluid level, it should be filled with fluid through the outlet port. If the pump is mounted below the fluid level, the pump outlet fitting (or other downstream fitting or plug) can be loosened to allow fluid to displace the air. It may be necessary to loosen the fill cap on the reservoir to allow the fluid to flow freely. When a solid stream of fluid with no observed air begins to drain through the loosened fitting, the fitting should be retightened. An air bleed valve in the outlet circuit is also recommended to remove trapped air. If such a device is used, the pump should be filled with fluid before start-up. In some cases, it may be possible to prime the pump by running the engine starter for five to ten seconds with the throttle and/or ignition switch in the "off" position. It will be necessary to loosen a fitting or plug in the pump outlet to allow air to escape. Pump Start-up All controls should be placed in the neutral position so the pump is unloaded when started. Start the engine and run at low idle. Once the pump is started, it should prime and pump within a few seconds. If it does not, make sure there are no restrictions between the reservoir and the inlet to the pump, and that there are no air leaks in the inlet line and connections. Also, make sure that trapped air can escape from the outlet. Run at low engine idle for approximately five minutes. Then, while observing the reservoir fluid level, operate the implements. Extend all actuators to maximum safe limits to completely fill the system with fluid. Do not run with the fluid level below the "low" limit. Add fluid to the reservoir to bring the fluid to the proper fill level.
