Henan San Kuang Machinery Technology Co., Ltd. is a professional manufacturer with over 10,000 square meters of factory space and a dedicated team of 51-100 employees. Our Heavy-Duty Coupling for Pump and Compressor is engineered to deliver reliable torque transmission in demanding industrial applications. With a maximum operating speed of 2000 RPM and a 40mm bore diameter, this coupling provides a robust connection between pump and compressor shafts, minimizing downtime and maintenance costs. Backed by a 1-year warranty and a range of certifications including ISO9001, ISO14000, and OHSAS18001, this product reflects our commitment to quality and safety.
This coupling is designed to withstand heavy loads, vibrations, and misalignment common in pump and compressor systems. Its precision-machined components ensure a tight fit and long service life, while the flexible design compensates for slight angular, parallel, and axial misalignments, reducing stress on connected equipment. The following table summarizes key technical specifications:
| Parameter | Value |
|---|---|
| Bore Diameter | 40 mm |
| Max Speed | 2000 RPM |
| Material | High-strength alloy steel (optional) |
| Torque Capacity | Up to 1500 Nm (customizable) |
| Misalignment Tolerance | Angular: ±1°, Parallel: 0.5 mm, Axial: ±2 mm |
| Weight | Approx. 5.5 kg (varies by configuration) |
| Operating Temperature | -20°C to +80°C |
Key Features and Benefits:
- High Durability: Manufactured from premium alloy steel with heat treatment, the coupling resists wear and fatigue even under continuous heavy-duty operation.
- Flexible Design: The elastomeric element or grid (depending on variant) absorbs shock loads and dampens vibration, protecting both the pump and compressor from damage.
- Easy Installation: Keyway and set screw included for simple mounting; no special tools required. Bore tolerance ensures a secure fit on 40mm shafts.
- Low Maintenance: Sealed construction prevents contamination from dust and moisture, extending service intervals. The coupling requires no lubrication in most applications.
- Versatile Compatibility: Suitable for use with centrifugal pumps, reciprocating compressors, blowers, and other rotating machinery with standard shaft sizes.
- Enhanced Safety: Complies with international safety standards (OHSAS18001) and comes with a protective guard option for added operator safety.
Customization Options: We offer bore sizes from 20mm to 80mm upon request, as well as alternative materials such as stainless steel or ductile iron. Surface treatments like zinc plating, black oxide, or industrial painting are available to meet specific environmental requirements. Please contact our sales team for custom configurations.
Quality Assurance: Every coupling undergoes rigorous testing including dimensional inspection, hardness test, and dynamic balancing to ensure zero defects. Our factory, spanning 10,000–30,000 square meters, is equipped with CNC machining centers and advanced testing equipment.
