Rotor Stator Sets for Plaster, Screed, Grout, 3D Concrete Printing & Tundish Pumps

The rotor stator unit is the central component of every mixing and delivery pump. This essential pump unit generates the required pressure to transport materials efficiently to the point of application.

Depending on the pump size and configuration, different conveying capacities can be achieved, ensuring optimal performance for a wide range of materials and applications.

Understanding Pump Performance and Pressure Stages

Each rotor stator is identified by a specific designation. The last digit indicates the number of pressure stages, with each stage capable of generating up to 10 bar of working pressure.

If the pump no longer reaches the required pressure levels, this is a clear sign of wear. In such cases, replacing the rotor stator ensures consistent performance and prevents operational downtime.

Types of Stators for Different Applications

To meet various operational requirements, different stator designs are available:

1. Maintenance-Free Stators

These stators are ready for immediate use after installation. They require no additional adjustment and offer a simple, time-saving solution for standard applications.

2. Tensible (Adjustable) Stators

Tensible stators allow for individual adjustment based on material type and grain size, providing greater flexibility and extended usability. They are divided into two main categories:

  • Stators with Integrated Clamp – Built-in clamping mechanism for quick and easy adjustment
  • Slotted Stators with External Clamp – Require an external clamping device for tensioning

When conveying pressure decreases, these stators can be retightened, significantly extending their service life and maintaining consistent performance.

Durable Design and Maximum Efficiency

All our rotor stator solutions are engineered for high durability, reliability, and performance. A robust design combined with advanced functionality ensures long service life, reduced maintenance, and optimal pumping efficiency—even under demanding conditions.

Frequently Asked Questions About Rotor Stator Sets

How do I know which rotor stator set fits my pump?

Check the part code or model on your pump. Even small differences can affect performance.
Pro Tip: Send us your pump details—we’ll confirm the exact match.

How often should I replace my rotor stator set?

It depends on usage, material, and operating conditions—not just time.
Pro Tip: Monitor performance signs rather than waiting for complete failure.

How do I read the rotor stator code?

The code (e.g., D6-3, 2L6) defines size and pitch. It’s usually found on the pump plate.
Pro Tip: Always match the code exactly to avoid compatibility issues.

What’s the difference between clampable and maintenance-free stators?
  • Clampable → easier to install/remove on-site
  • Maintenance-free → simpler design with fewer adjustments

Pro Tip: Choose based on your working conditions and maintenance preferences

What rubber hardness should I choose?

 It depends on the material:

  • Abrasive mixes → softer rubber
  • Smooth materials → harder rubber

Also important to keep in mind that the hardness of the rubber has an impact on the pressure. The harder the rubber the more pressure the pump generates. 

Pro Tip: Matching rubber to material significantly increases lifespan.

Should I replace both rotor and stator at the same time?

Yes, this ensures optimal performance and prevents uneven wear, especially in a rotor and stator pump setup.
Pro Tip: A new stator with a worn rotor will wear out faster.

What are the signs of wear?
  • Pressure loss
  • Pulsating flow
  • Clogging
  • Rubber degradation

Pro Tip: Early replacement saves time and money.
