As a trusted supplier with over a decade of experience in industrial fluid handling, Rossonix Co., Limited proudly presents the SEIM Triple Screw Pump PCXAO — a heavy-duty three screw pump specifically engineered for demanding lubrication systems. This pump combines robust construction with precision engineering to deliver reliable, continuous oil circulation in machinery where downtime is not an option. Designed for durability and efficiency, the PCXAO series ensures minimal pulsation, low noise, and long service life, making it an ideal choice for lubrication of large gearboxes, turbines, compressors, and other rotating equipment.
The PCXAO triple screw pump operates on the principle of three intermeshing screws that create a positive displacement action, providing a smooth, almost pulse-free flow. This design is particularly suited for handling lubricating oils with viscosity ranging from 2 to 4000 cSt. The pump's heavy-duty construction includes hardened screws and robust bearing housings, ensuring resistance to wear even under continuous operation. Below are the key technical specifications:
| Parameter | Specification |
|---|---|
| Flow Rate | Up to 2000 L/min (customizable) |
| Max Pressure | 16 bar (higher on request) |
| Viscosity Range | 2 – 4000 cSt |
| Temperature Range | -20°C to +120°C |
| Material of Screws | Nitrided Steel / Case Hardened Steel |
| Body Material | Cast Iron / Ductile Iron (optional stainless steel) |
| Mounting Orientation | Horizontal or Vertical |
| Drive | Direct coupled to electric motor or diesel engine |
Key Features & Benefits:
Self-Priming Capability: The pump can lift oil from a reservoir up to 5 meters, simplifying installation.
Low Noise & Vibration: Triple screw design ensures balanced axial forces, resulting in quiet operation below 70 dB(A) under normal conditions.
High Efficiency: Volumetric efficiency exceeds 95% for most lubricating oils, reducing energy consumption.
Extended Service Life: Hardened screws and replaceable liners offer wear resistance, with typical service intervals exceeding 20,000 hours.
Versatile Configurations: Available with various seal options (mechanical seal, lip seal) and relief valves for system protection.
Easy Maintenance: Cartridge design allows quick replacement of internal components without disconnecting piping.
The PCXAO series is widely used in lubrication systems for steel mills, power plants, marine engines, wind turbines, and heavy machinery. Its ability to handle high-viscosity fluids with minimal shear makes it particularly suitable for synthetic oils and gear oils. The pump can be integrated with filtration and cooling systems to maintain oil quality over extended periods.
