Pump Cutting Rings DN200-260 for Putzmeister Schwing Concrete Pumps
Cutting Ring: The Guardian of the S-Valve
Concept:
The cutting ring is a hardened steel component that acts as a sharp, durable seal on the swinging S-tube of a concrete pump.
Purpose:
It is designed to cleanly cut through debris and create a perfect seal against the wear plate during the S-tube's shifting action. This ensures no concrete is wasted and full pumping power is maintained with every cycle.
Benefits:
-
Maximizes Efficiency: Ensures optimal sealing for consistent pumping pressure and output.
-
Reduces Downtime: Its robust construction provides extended life, meaning fewer stoppages for maintenance.
-
Cost-Effective: Protects the more expensive S-tube and wear plate from damage, lowering long-term operating costs.
-
Reliable Performance: Guarantees smooth operation even with harsh and abrasive concrete mixtures.


- High hardness: Hard alloy construction resists abrasion
- Strong wear resistance: Engineered for long-term friction resistance
- High pressure adaptability: Maintains seal integrity under extreme pressure
- Reinforced vulnerable parts: Specialized surfacing welding improves durability
