CHDF Horizontal Multistage Pump

Technology Innovation & Design Advances

Analysis of key innovations in CHDF series including advanced materials, precision manufacturing, and innovative hydraulic design.

1. Material Innovation

All-stainless-steel construction (AISI304) provides corrosion resistance, hygiene, and 2-3x service life compared to cast iron.

2. Hydraulic Design

3D optimized impeller profiles (CFD-designed), smooth surface finish (Ra ≤1.6μm), balanced for minimal axial thrust.

3. Manufacturing Excellence

CNC machining, CMM inspection, laser welding, automated balancing ensure consistent quality.

4. Performance

Flow: 2-180 m³/h, Head: Up to 305m, Efficiency up to 75%, MEI ≥0.50.
