Rotors & Stators

Helpful Guide for Rotors and Stators in Plastering Machines

The rotor and stator are essential components of a plastering machine's pump unit. The rubber stator remains static while the steel rotor rotates, drawing mixed material through the stator and pushing it into the material hose. The output is determined by the rotor and stator size.
For example, the PFT G4 uses a standard D6-3 rotor and stator with a 20-22 L/min output, adjustable with different "D" pumps. Slower pumps (6-14 L/min) are ideal for thin applications, mid-range pumps (18-25 L/min) for one-coat renders, and high-output pumps (25-35 L/min) for floor screeds.
Rotor and stator wear depends on usage, typically lasting between 15-25 tons of render. Larger units, like the R8 1.5, can pump up to 80 L/min for high-volume tasks.
Machines like the PFT Ritmo and Swing use specific rotor and stator types for varied outputs. For advice on selecting the right rotor and stator, contact
