What are the relevant factors in choosing a rotor stator?

Size, diameter, material particles and the flow rate you want to achieve. You need to choose the rotor stator based on the size and diameter of the rotor stator, also depending on the particles of the material and the required flow rate. Different rotor stator pumps are suitable for different materials and uses to achieve different pumping effects. Different screw pump designs allow for different flow rates and pressure stability.

Maintenance-free or clamp-on rotor stators?

Maintenance-free stators are more user friendly. They can be used directly after they are installed on the machine. They have no channel steel pipe as a housing. This means they allow for constant pressure to deliver and support a hassle-free process. The stator can be clamped according to material and grain size. They come in two types: stators with built-in tensioning clips and slotted stators with external tensioning strips.

Both can smoothly and continuously transport a wide range of materials with minimal pulsation. Pumps that require clamping have an integrated clamping rod, or a grooved stator for clamping, with or without additional individual clamps. When the conveying pressure drops, the stator must be re-tightened.
