Screw pump

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

Overview of the screw pump.

Screw pumps are used for pumping various types of fluids, emulsions, are well suited for pumping pulp. Using a screw pump allows pumping of thick and viscous fluids containing various kinds of hard and abrasive inclusions of particles and gas-containing products. The screw (gyratory) pumps are widely used in almost all sectors of the economy. Special distribution they received in food, pharmaceutical, cosmetic, chemical, petrochemical industries). Applying screw pumps eliminates foaming and the destruction of the product structure in the process of pumping of the latter.

Screw pump need not be provisionally in the Gulf fluid inlet.

food processing industry

Screw pumps are widely used in food, particularly in the dairy industry for pumping products such as milk, cream, whey, oil or melted fat. Pumps of this type are also widely used for pumping all kinds of drinks, jams, sauces, jams, honey, etc. Pump housings and rotors oriented food industry are made of stainless steel, and the inner coating of the stator is made of polymers approved for food contact.

Cosmetic industry

In the cosmetic industry screw pumps are used, usually when pumping these cosmetic products such as scrubs, lotions, shampoos, soap, shower gel, toothpaste, etc.

Chemical industry

In the chemical industry gerotor pumps are used in pumping a wide variety of products including adhesives, paints, lacquer, polymers, paint products, acids, detergents, chemicals, dyestuffs, inks, various types of solutions, etc.

For this oriented pump housing industry, the rotors and the stator inner coating made of materials resistant to the most specific type of product, which significantly increases the pump life in general.

The operating principle of the screw pump.

By rotating the screw by the cavity inlet expands and creates a negative pressure in it, under the action of which the filling of the cavity of the transported medium. Further rotation of the screw moves the cut off volume of product transported in the direction of the discharge nozzle. The operation of the screw pump principle is the use of the gerotor mechanism, wherein the rotor (screw) makes a planetary motion in the stator (yoke) with the displacement volume of the transported product in the closed cavities between the rotor and the stator.

Advantages and disadvantages of screw (gerotor) pumps. The advantages of the use of screw pumps are: volume effect; smooth non-pulsating flow; pressure is independent of the speed of the pump; quiet operation; the ability to operate without the product for a short time; the possibility of folding the washing; vibration-free dosing pump; Easy and durable stainless steel construction; simple operation; low cost; ability to pump viscous liquids and slurries, fluid inclusions; no cavities in the working chamber; The disadvantages of the use of screw 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 metal); restriction when pumping corrosive products (depending on the type of metal);

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 configuration. • high-temperature food, including and self-priming pumps homogenizers and own production
