1. What are rotor stator pumps, and how do they work?
Rotor Stator pumps are progressive cavity pumps – a type of positive displacement pump. They can be used for pumping various viscous and abrasive fluids.
The fixed stator and the rotating component, the rotor, are the yin and yang of progressive cavity pumps. The rotor is the spiral steel shaft that creates conveying chambers of the inner outline of the rubber tube. Stators are metal tubes with internally molded cavities made of synthetic or natural rubber.
When the rotor is triggered, the conveying chambers move in the direction of flow. This is how the constant flow of material is achieved. The rotor takes a form which resembles a corkscrew, which, combined with the off-center rotary motion, gave its alternative name: eccentric screw pump.
2. What are rotor stator pumps used for?
Various industries use progressive cavity pumps. Putzparts is specialised in rotor stators for the construction and refractory industry to pump screed, mortar, grout, gypcrete, plaster and fireproofing cement.
Rotor stators also cater to wood processing and cellulose production, the chemical industry, the petroleum industry, domestic and industrial sewage, and low flow, high head, and agricultural water pumping.
3. How to choose the right shore for your rotor stator?
The shore is very significant: the smaller the number of the shore, the softer the rubber. We recommend a soft rubber if you pump material with sharp aggregates, as they wear out less quickly.
A harder rubber generates more pressure.
When choosing your optimal shore, consider your working temperature and climate, as rubber softens in heat. Our customers in warmer climates prefer a stator with harder rubber. Similarly, customers in temperate regions alternate shores based on seasonal weather shifts.
