2L7 Rotor Stator Set

High-Output Screw Pump for Bosch Pump & Putzmeister Applications – 240 l/min

Made in Germany

The 2L7 Rotor Stator Set is a high-output progressive cavity pump used for the Bosch Pump and compatible Putzmeister applications.

With a flow rate of 240 l/min at 400 RPM, a maximum grain size of 10 mm, and a large 127 × 540 mm stator, the 2L7 is designed for professional material pumping applications requiring substantial conveying capacity.

The complete set combines a high-alloy tool steel rotor with a red 56 Shore stator featuring an integrated clamp. The rotor head is designed with a slit and drill hole.

Machine Compatibility

The 2L7 is suitable for:

• Bosch Pump
• Compatible Putzmeister pumping equipment

The exact machine configuration and rotor connection should be checked before ordering.

High-Output Performance

The 2L7 provides:

• 240 l/min at 400 RPM
• 120 l/min at 200 RPM

This high conveying capacity makes the 2L7 suitable for professional pumping applications requiring substantial material throughput.

Integrated Clamp Stator

The red 2L7 stator features an integrated clamp.

The integrated clamp allows the stator tension to be manually adjusted when required. This can be used to compensate for wear and adjust the stator tension during operation.

A separate external clamp is not required.

Excessive tightening should be avoided, as too much stator tension increases friction and can reduce the service life of the rotor and stator.

Rotor with Slit & Drill Hole

The matching 2L7 rotor is manufactured from high-alloy tool steel.

The rotor head features a combination of:

• Slit
• Drill hole

This rotor head configuration should be matched to the corresponding machine and drive connection.

Benefits

High Output – 240 l/min

With 240 l/min at 400 RPM, the 2L7 provides high conveying capacity for demanding professional material pumping applications.

Up to 10 mm Grain Size

The pump is suitable for compatible pumpable materials with a maximum grain size of 10 mm.

High-Alloy Tool Steel Rotor

The matching rotor is manufactured from high-alloy tool steel and features a slit and drill hole in the rotor head.

56 Shore Stator

The red stator uses a 56 Shore rubber compound and measures 127 mm in diameter and 540 mm in length.

Adjustable Stator Tension

The integrated clamp allows the stator tension to be adjusted when required, providing additional flexibility during professional operation.

Complete Rotor Stator Set

The 2L7 is supplied as a complete rotor and stator combination, providing the two central components of the progressive cavity pump as a matched set.

Applications

The 2L7 is suitable for compatible:

• Mortar
• Screed
• Pumpable construction materials
• High-volume material conveying
• Material pumps
• Construction pumps
• Progressive cavity pumps
• Bosch Pump and compatible Putzmeister applications

Always observe the specified maximum grain size of 10 mm.
