Impeller pump

Shtolverk Company develops, manufactures and sells centrifugal pumps of various designs and modifications for the food, cosmetic, pharmaceutical, paint, chemical and other industries.

General information on the pump impeller.

Impeller pumps are used for pumping liquids of a wide range in m. Hr. With a content of various kinds of solids and particles, and the gas-containing products. Using the self-priming pumps with flexible impeller eliminates the destruction of the product structure in the process of transfer of the latter. Impeller (all season, self-priming) pumps are widely used in various industries (food, pharmaceutical, cosmetic, chemical industry).

Impeller pump is self-priming pump and therefore does not Bay need preliminary liquid into the inlet. Using the pump impeller allows to raise product with depths up to 5 meters.

The principle of operation of the pump impeller.

The operation of the impeller pump principle are non-symmetrical cross-section casing and impeller with flexible lamellae (impeller). Upon rotation of the impeller inlet in the volume area increases between adjacent lamellae, resulting in a discharge and the liquid flows into the pump housing. Next fluid gradually moves from the inlet to the discharge. The discharge nozzle area due to the asymmetry of the shape of the hull volume between adjacent slats of the impeller is reduced, thereby displacing the product.

Food processing industry

Impeller pumps are widely used in food, particularly in the dairy industry for pumping products such as milk, cream, melts oils (including palm) and fats, as well as various types of beverages. They are widely used for pumping products with low and medium viscosity with inclusions (pastry cream, jam, etc.).

Pump housings oriented food industry are made of stainless steel, and the impellers are made of polymer materials approved for contact with food. Impeller pumps fully meet the stringent sanitary requirements.

Cosmetic industry

In the cosmetics industry impeller pumps are mainly used for pumping such cosmetic products as soap, gel, cream, toothpaste, etc.

Chemical industry

In the chemical industry impeller pumps are used in pumping a wide variety of products, in particular paints and varnishes, acids, detergents, chemicals, dyestuffs, inks, various types of solutions, etc.

For pump impellers oriented to this industry are made of a chemically resistant rubber, which significantly increases the pump life in general.

Advantages and disadvantages of flexible impeller pumps.

The advantages of using impeller pumps are:

  • the ability to operate without the product for a short time;
  • simple operation;
  • low cost;
  • simple structure;
  • the possibility of product recovery from a depth of 5 meters;
  • ability to handle liquid fluid inclusions;
  • no cavities in the working chamber;
  • the possibility of reversing operation; 

    The disadvantages of using impeller pumps are:

  • no possibility of continuous operation in the absence of the product being pumped;
  • limit temperature of the pumped product (depending on the type of elastomer);
  • restriction when pumping corrosive products (depending on the type of elastomer);
  • the presence of the wear member.

Additional accessories:

Any equipment can be equipped with additional snap in any volume and configuration:

• Fully automatic control system with touch panel with TOUCH-general industrial multi-channel programmable controller for full control and management, temperature, time and mixing modes, as well as the management of pumping and homogenizing equipment.
• audible and visual alarm system
• system of protection against "dry run"
• timers and time switches
• The system is monogamous or tiered as well as combined heating / cooling
• circulation pumps for high-temperature heat carrier
Level sensors (mechanical, ultrasonic, laser,
Pressure transducers)
• strain gauges
• Automatic vacuum or injection systems, as well as
injection of steam into the product
• mixing devices and high-speed low-speed, any
• high-temperature food, including and self-priming pumps
homogenizers and own production
