Can you explain what rotor stator pumps are and how they operate?

Progressive cavity pumps, which are what Rotor stator pumps are, fall under the category of positive displacement pumps. Pumping screed, mortar, grout, plaster, and cement are some of the uses for these machines.

In progressive cavity pumps, the yin and yang are represented by the stator, which is fixed, and the rotor, which is the rotating component. The spiral steel shaft that creates conveying chambers along the inner outline of the rubber tube is called the rotor. Stators are tubes made of metal that have cavities made of natural or synthetic rubber that have been molded inside of them.

The conveying chambers will move in the direction of flow when the rotor is activated. This is the method by which the continuous flow of material is accomplished in practice. Because of the rotor's shape, which is reminiscent of a corkscrew, and the pump's characteristic off-center rotary motion, another name for the device is an eccentric screw pump.

2. What are the applications for rotor stator pumps?

The majority of our clients put rotor stators to use in the construction industry, specifically for pumping grout, screed, mortar, plaster, and refractory tundish. However, rotor stators are also frequently utilized in the food, pharmaceutical, and cosmetics industries for the purpose of processing colloidal liquid and liquid systems, as well as to disperse or break up solid particles and aggregates. Rotor stators are utilized in the processing of wood and the production of cellulose, as well as in the chemical industry, the petroleum industry, the treatment of sewage in both residential and commercial settings, and the pumping of low volumes of water at high pressures in agricultural settings.
3. What are the important considerations to keep in mind when selecting the rotor stator?

Dimensions such as the size and diameter of the material, the grain size, and the desired flow rate

You will want to select your rotor stator not only on the basis of its size and diameter, but also with consideration given to the grain size of the material you will be processing and the flow rate you intend to achieve. The same material can be pumped with one type of rotor stator pump, but using it for a different purpose will yield a different set of results. Screw pumps can be designed in a variety of ways, each yielding a unique combination of flow rates and pressure stability.

4. Rotor stators that require no maintenance or those that can be clamped?

Stators that don't require regular maintenance are easier to use. They are ready for use as soon as they have been installed in the apparatus. As outer casings, they are constructed out of solid steel tubes. This indicates that they are able to support a process that is hassle-free and allow for constant delivery pressure.

Stators that can be clamped are typically clamped in accordance with the material and grain size. They are available in two different varieties: slotted stators, which are provided with an external tensioning strip, and stators that already have built-in tensioning clamps.

Both of these methods are capable of transporting a wide variety of materials in a smooth, continuous, and pulsation-free manner. Pumps that need to be clamped have either an integrated clamping bar or a grooved stator for the clamp. These pumps may or may not have a separate clamping device as well. It is necessary to retighten the stators whenever there is a drop in the delivery pressure.

5. How do you determine which shore will work best for your rotor stator?

The shore works with rubber of varying hardnesses and qualities of varying degrees of softness.

The shore plays an extremely important role: the fewer there are, the more difficult the rubber will be to work with. The material is considered to be relatively soft if it has a greater shore. If you need rubber that is more durable, you should choose a shore with a smaller depth. However, certain materials perform better when paired with a more flexible rubber. Rubber may become damaged if harder materials with pointy aggregate are used.

Because rubber becomes more malleable when exposed to heat, one must take into account the working temperature and climate when selecting the ideal shore. Our customers who live in hotter climates gravitate toward a stator that is made of a more durable rubber. Customers who live in temperate regions, on the other hand, frequently switch shores due to the cyclical changes in the weather.

6. Does Putzparts provide rotor stator pumps that are of a high quality?

Germany is the country of origin for Putzparts' rotor stators. Never will you find a hollow spot in one of our high-alloyed steel rotors. For rotors that last a long time, we use high-quality steel that has been precisely drilled. Because we use high endurance rubber in our stators, they are designed to last for a very long time, to be reliable, and to support a pumping experience that is both stable and consistent.

7. Am I able to use the pumps with other types of machines?

Rotor stator pumps are available from us for a wide range of different machines, including those manufactured by Putzmeister, PFT, M-Tec, Uelzener, Turbosol, Mai, Utiform, Inotec, Imer, Brinkmann, and a great number of others. Numerous machines all use the same kinds of rotor and stator.

The D6-3 is the most widely used pump for plaster because it provides a consistent output of 30 liters per minute while rotating at 400 revolutions per minute. If you require more, one option is to purchase the D8-2, which, with a capacity of 66 liters per minute, has a higher output than any other D-pump.

We suggest going with either the 2L6 or the 2L88 when it comes to floor screed conveyors like the Putzmeister S5. These pumps are available in a variety of configurations. You have the choice between stators that require no maintenance and those that can be clamped, allowing you to use an external clamp.

8. The rotor stator that I'm looking for is nowhere to be found. Are there a variety of types available from you?

Most likely, yes. In addition to carrying a wide variety of rotor stator pumps in our shop, we can also produce custom series of nearly any stator size at prices that are in line with your budgetary requirements.

Please get in touch with us if you are unable to find what you are looking for or if you require assistance in determining what would be most beneficial to you.
