Lorentz PU600 CS-17-1 Spare Part Screw with Protector Fig.21
Modelo: 35-000200 Screw with protector, For PE CS-17-1 / CS-37-1- Sku: LOREREP054
- Vendor: Lorentz
Specifications
Product Description
The Lorentz PU600 CS-17-1 Fig.21 Screw with Protector is the original fastening element that secures the impeller/diffuser assembly in the pump. Its design incorporates a protector that distributes the load and prevents damage from contact, maintaining stable tightening even under vibrations. It is a critical component to preserve the alignment of the impeller, the sealing of the mechanical seal, and the hydraulic efficiency of the system in treatment plants and recirculation circuits powered by solar energy.
Main Features
- Original Lorentz spare part for PU600 CS-17-1, position Fig.21 in the exploded view.
- Screw + protector assembly for correct support and uniform distribution of forces.
- Thread and length calibrated for the hydraulic assembly housing.
- Prevents loosening due to vibration and protects seating surfaces.
- Dimensional compatibility with impeller (Fig.6) and diffuser (Fig.7).
- Steel and technical polymer suitable for continuous operation in humid environments.
Advantages or Benefits
- Keeps the secure fastening of the impeller, preventing noise and performance losses.
- Reduces the risk of eccentricities that accelerate mechanical seal wear.
- Simple, quick assembly with repeatable tightening torque.
- Greater reliability by using original replacement with factory tolerances.
Purpose or Applications
Recommended when vibrations, noises, or signs of play are observed in the impeller, or after any maintenance intervention involving disassembly of the hydraulic assembly. Suitable for solar pool treatment plants and recirculation circuits using the PU600 CS-17-1 pump.
