75.15 (7515) Rotor Stator Set

High-Output Screw Pump for Screed & Material Conveying – 400 l/min

Alternative names: 7515, 75-15, 1.5L7, Tornado

Made in Germany

The 75.15 Rotor Stator Set, also known as 7515, 75-15, 1.5L7, or Tornado, is a large high-output progressive cavity pump used in professional screed and material conveying equipment.

With a flow rate of 400 l/min at 400 RPM, a stator diameter of 159 mm, and a maximum grain size of 8 mm, the 75.15 is designed for applications requiring substantial material output.

The 75.15 is used in machines from manufacturers including Bremat, Overmat, Mixmobil, Glaap Brinkmann, BMS, Putzmeister, Brinkmann, and Euromair.

Three stator configurations are available: the white Standard maintenance-free stator, the orange Premium maintenance-free stator, and an orange stator with integrated clamp. All versions are combined with the matching rotor manufactured from high-alloy tool steel with a hexagonal rotor head.

Machine Compatibility

The 75.15 / 7515 is used in a wide range of professional pumping and screed machines, including:

• Bremat
• Overmat
• Mixmobil
• Glaap Brinkmann
• BMS
• Putzmeister SP25
• Putzmeister SP20

• Brinkmann FHS250
• Brinkmann FHS200
• Euromair D200
• And other compatible machines

Due to the large number of machines using this pump type, always verify the required rotor stator configuration before ordering.

Three Stator Configurations

The 75.15 is available with three different stator options.

Standard – White, Maintenance-Free

The Standard 75.15 stator is white and features a maintenance-free design.

It is equipped with one 25 × 12 × 45 mm anti-twist device and does not require manual tension adjustment during normal operation.

Premium – Orange, Maintenance-Free

The Premium 75.15 stator is orange and also features a maintenance-free design with one anti-twist device.

The Premium version is priced higher than the Standard white stator but is designed to provide a longer service life.

This version is particularly suitable when reducing replacement frequency is a priority.

Integrated Clamp – Orange

The third option is an orange 75.15 stator with integrated clamp.

The integrated clamp allows the stator tension to be adjusted when required without using a separate external clamp.

This version provides greater flexibility for operators who prefer an adjustable stator configuration.

Benefits

Very High Output – 400 l/min

The 75.15 provides:

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

This high conveying capacity makes the 75.15 particularly suitable for professional applications requiring large material volumes.

Up to 8 mm Grain Size

The pump is suitable for compatible pumpable materials with a maximum grain size of 8 mm.

High-Alloy Tool Steel Rotor

The matching 75.15 rotor is manufactured from high-alloy tool steel and features a hexagonal rotor head.

63 Shore Stator

All three stator configurations use a 63 Shore rubber compound and measure 159 mm in diameter and 550 mm in length.

Choice of Standard, Premium or Adjustable Stator

Depending on the application and operating requirements, customers can choose between:

• Standard maintenance-free
• Premium maintenance-free with longer service life
• Integrated clamp for adjustable tension

This makes the 75.15 suitable for different operating conditions and maintenance preferences.

Applications

The 75.15 / 7515 is suitable for compatible:

• Screed
• Mortar
• High-volume material conveying
• Screed pumps
• Material pumps
• Progressive cavity pumps
• Professional construction equipment

Always observe the specified maximum grain size of 8 mm.

Alternative Names

The same rotor stator pump is commonly known under several names:

• 75.15
• 7515
• 75-15
• 1.5L7
• Tornado

These designations refer to the same general rotor stator pump type.
