Product Specifications
While every shaft is customized to your specifications, the following capability ranges represent our most commonly delivered solutions:
| Capability Range | Typical Application | Shaft Diameter | Length | Weight |
| PS-100 | Medium-duty industrial pumps | Ø100–160 mm | 800–1,500 mm | 200–800 kg |
| PS-200 | Heavy-duty process pumps | Ø180–260 mm | 1,500–2,500 mm | 0.8–2.5 t |
| PS-350 | Large industrial pumps | Ø280–380 mm | 2,500–4,000 mm | 2.5–5 t |
These ranges serve as guidance. Every shaft can be engineered to meet your functional requirements within our proven manufacturing limits.
- Materials: 42CrMo4, 34CrNiMo6, AISI 4140/4145
- Heat Treatment: Quenching & Tempering (Q&T)
- Mechanical Properties: High strength, toughness, and wear resistance suitable for continuous industrial operation
- Forging: High-quality free forging ensures optimal grain structure and strength.
- Rough Machining: Reduces material stress and prepares for precision finishing.
- Precision Machining: Step diameters, bearing seats, external keyways, and shaft ends machined to tight tolerances.
- Surface Finishing: Functional surface zones achieve required Ra and hardness levels.
Quality & Inspection
- Dimensional Accuracy: IT7–IT8 for critical diameters
- Straightness & Concentricity: ≤0.03–0.05 mm, depending on size
- Non-destructive Testing: Ultrasonic or Magnetic Particle Testing (per customer requirement)
- Hardness & Mechanical Testing: Verified per specification
Our rigorous quality protocols ensure that every pump shaft meets performance expectations and longevity requirements.
Design Boundaries & Non-Applicable Features
- Nuclear-grade applications
- Internal splines or internal gears
- Ultra-high-speed rotors
- Deep internal bores
To maintain manufacturability and reliability, the features above are outside our current scope.
