Process-Driven Pump Selection
Optimized for Specific Operational Demands
Coarse Screening Stage
- Challenge: String-like plastic rope impurities prone to tangling
- Solution: Open Impeller Pumps
- Design: Non-clogging open impeller (passes solids up to 50mm)
- Material: Duplex stainless steel (SAF 2205)
- Flow Range: 50-800m³/h
- Features: Effectively prevents string-like plastic rope impurities from tangling, ensuring non-clogging operation
De-sanding Stage
- Challenge: High content of impurities, significant abrasion
- Solution: Abrasion-Resistant Material Pumps
- Design: Closed impeller pumps suitable for high-abrasion environments
- Material: High-chrome cast iron (HRC 58-62) or ceramic-coated shafts
- Pressure: 0.3-0.8MPa
- Features: High hardness materials (up to HRC 65), extending service life and reducing maintenance frequency
Fan Pump (Approach Flow System)
- Challenge: Low pulse for stable pulp quality
- Solution: Low-Pulse Centrifugal Pumps
- Pulse Rate: ≤±1.5% (vs. 5% in standard pumps)
- Design: Double-suction impeller with volute diffuser
- Material: 316L stainless steel for chlorine resistance
- Features: Provides stable pulsation rates, ensuring consistency in the headbox and pulp quality
Chemical Additives
- Challenge: Different chemicals require specific materials and shear protection
- Solution: Adaptable Screw Pumps and Other Pump Types
- Design: Select appropriate pump types based on chemical properties (e.g., magnetic drive pumps, PTFE-lined pumps)
- Material: PTFE lining or other corrosion-resistant materials
- Features: Zero leakage design, shear protection, suitable for various chemical additives
