Screw Channel Impeller Pumps

Industrial screw channel impeller pumps, also known as screw pumps or worm pumps, are a special type of pump used for pumping viscous or abrasive liquids. They are characterized by their unique design principle, in which two or more screws or augers rotate inside each other and move the pumped medium along the screw surfaces.

The most important features and applications of industrial screw channel impeller pumps are

• Screw movement: Screw channel impeller pumps use the principle of screw movement, in which the screws rotate in a convoluted or spiral arrangement and transport the pumped liquid efficiently along the screw surfaces.
• Viscous liquids: These pumps are particularly suitable for viscous liquids, pastes, sludge or liquids with a high solids content.
• Low degree of pulsation: Screw channel impeller pumps have a low degree of pulsation, which results in an even and stable flow of the pumped liquid.
• Non-clogging: Thanks to their design, screw channel impeller pumps can pump liquids with a high solids content without clogging.
• Suitable for abrasive media: You can also pump abrasive liquids without excessive wear.
• Areas of application: Screw channel impeller pumps are used in applications such as waste water treatment, the chemical industry, food processing, paper manufacturing and mining, where viscous or abrasive media need to be pumped.
• Gentle delivery: Due to their gentle delivery, they are particularly suitable for sensitive or shear-sensitive liquids.
• High viscosity: They are effective in pumping media with high viscosity, where conventional pumps may reach their limits.
• Consistent performance: Screw channel impeller pumps offer constant performance, regardless of pressure fluctuations or viscosity changes.
• Low maintenance: Thanks to their non-clogging design and low tendency to wear, screw channel impeller pumps require little maintenance.

These pumps offer a reliable solution for demanding applications where viscous, abrasive or solid-containing liquids need to be pumped. They ensure gentle conveying and can be used in various industrial environments.

The most important areas of application for industrial screw channel impeller pumps are

• Waste water treatment: Screw channel impeller pumps are often used in sewage treatment plants to pump viscous waste water, sludge and other viscous media with a high solids content.
• Chemical industry: In the chemical industry, screw channel impeller pumps are used to pump viscous chemicals, suspensions and paste-like substances.
• Food processing: These pumps are ideal for conveying food ingredients such as dough, syrup, sauces, creams and other highly viscous food products.
• Paper production: In the paper industry, screw channel impeller pumps are used to convey paper pulp, fillers and other liquids with a high solids content.
• Mining: Screw channel impeller pumps are used in the mining industry to pump slurry, ores and other abrasive or viscous materials.
• Oil and gas industry: In the oil and gas industry, screw channel impeller pumps are used to pump viscous oils, slurries and residues.
• Environmental technology: These pumps play a role in environmental technology to pump sludge, waste and other materials from industrial processes.
• Construction site dewatering: Screw channel impeller pumps are used on construction sites to efficiently pump out sludge, water and other materials.
• Agriculture: In agriculture, these pumps are used to pump fertilizer, animal feed or liquid manure.
• Textile industry: Screw channel impeller pumps can be used in the textile industry for pumping color and dyeing additives.

The versatile properties of screw channel impeller pumps, such as their ability to pump viscous, abrasive and solids-laden media, make them an important component in various industrial applications where conventional pumps would not be effective.
