D4-1/4 Rotor Stator Set

D4-1/4 Progressive Cavity Pump Set

Made in Germany

The D4-1/4 Rotor Stator Set is a premium-quality progressive cavity pump set designed for precise conveying performance in low-output construction and industrial applications. Manufactured in Germany, it combines a precision-machined rotor made from high alloy tool steel with a high-quality stator, ensuring reliable pressure build-up, excellent wear resistance, and long service life.

The stator has a diameter of 89 mm and a length of 270 mm. Manufactured from 73 Shore rubber, it provides excellent sealing characteristics and dependable pumping performance when conveying materials with a maximum grain size of 2 mm.

At 400 / 200 RPM, the pump set delivers an approximate flow rate of 8 / 4 l/min, making it ideal for fine mortar, grouting, injection, and other applications requiring accurate material delivery.

Available Stator Versions

The D4-1/4 Rotor Stator Set is available with two different stator versions:

• Black stator with an integrated clamp
• Blue maintenance-free stator

If you are unsure which stator version is best suited for your machine or application, please contact us. Our team will be happy to help you select the correct configuration.

The hardened high alloy tool steel rotor and precisely matched stator provide optimum sealing, smooth material flow, and reduced wear for maximum service life.
