At Putzparts, we supply high-performance stator pumps and pump stators designed for consistent material flow across plaster, screed, mortar, and grout applications. As a key part of any rotor stator pump system, the stator works with the rotor to move material efficiently from the hopper to the nozzle. 

Because stators operate under constant friction and pressure, they wear over time, which can lead to pressure loss, uneven flow, and reduced efficiency. Choosing the right pump stator helps maintain consistent output and avoid costly downtime. In many cases, professionals replace both components together as a complete rotor stator set to restore full performance and prevent uneven wear. 

With over 25 years of experience, we provide durable, precision-engineered stator pumps built for reliable performance in demanding job site conditions.

Selecting the correct stator directly affects your pump’s pressure, flow consistency, and overall performance. The wrong stator can lead to inefficient operation, increased wear, and unnecessary maintenance costs.

Here’s how choosing the right stator pump prevents common issues:

• Wrong Type (Maintenance-Free vs Clampable): Loss of pressure control and reduced lifespan
• Incorrect Shore Hardness: Faster wear or insufficient pumping pressure
• Wrong Size or Model: Poor compatibility, pressure drops, and inefficient material flow

We supply flexible stators and standard configurations compatible with leading brands such as Putzmeister, PFT, M-Tec, and Ülzener. If you already know your stator model (e.g., D6-3, 2L6, UE 45/7), you can find it directly in the product grid above.

If you’re unsure, simply share your machine model with us — we’ll identify the correct pump stator within one business day.

Our customers rely on Putzparts because we provide stator solutions that balance durability, performance, and ease of use in real job site conditions.

• Built for Durability: Our stator pumps are manufactured in Germany using high-quality rubber compounds designed to withstand abrasion, pressure, and continuous operation.
• Flexible Options for Every Application: We offer both maintenance-free and clampable flexible stators, allowing you to choose between simplicity or extended service life through adjustment.
• Wide Compatibility: Our stators are designed to fit a broad range of machines from leading manufacturers, ensuring seamless integration and reliable performance.
• Fast & Reliable Shipping: We understand the cost of downtime. Most in-stock stators ship within 1–2 business days.

Expert Support When You Need It: Not sure what you need? Our team is ready to help you select the right stator pump based on your machine and application.

Maintenance-free stators are designed for simplicity — install and operate with consistent pressure throughout their lifespan, without adjustment. Clampable stators allow you to retighten and restore pressure as the rubber wears, extending usability but requiring periodic adjustment.

Pro Tip: If you are replacing a stator, match the type of your current one for the best results.

The rubber hardness of your stator plays a key role in how it performs under different conditions.

• Softer stators handle abrasive materials better and reduce internal wear
• Harder stators generate higher pressure and perform better in warm conditions

Pro Tip: For plaster and fine materials, harder stators work well. For screed or abrasive mixes, softer options provide longer life.

Each stator model is designed for specific pump sizes and outputs. Using the correct size ensures stable pressure, smooth flow, and efficient operation.

Pro Tip: Always confirm the stator model (e.g., D6-3, 2L6) rather than relying only on machine brand.

For optimal performance, your stator should always work in proper alignment with the rotor. A worn rotor can reduce efficiency and accelerate wear on a new stator.

Pro Tip: If your rotor is still in good condition, you can replace only the stator or purchase individual rotors as needed, saving cost while maintaining proper alignment.
