ONB-SP Series Food Screw Pumps

Belgorod Hydromechanical Plant is a Russian manufacturer of screw pumps of the ONV-SP series, specially adapted for safe and efficient operation in the food industry. The company independently designs and manufactures key components, including gerotor pairs, ensuring full quality control, compliance with sanitary standards and stable performance.

Scope of application

Pumps of the ONB-SP series are designed for gentle and precise movement of a wide range of food media:

• dairy products (sour cream, yogurt, cottage cheese, soft cheeses, whey, condensed milk);
• sauces and ketchups (tomato paste, mayonnaise, mustard, oil-based sauces);
• confectionery products (chocolate, glazes, jams, creams, condensed milk, batter);
• meat and fish products (minced meat, pastes, fat emulsions, marinades, brines);
• beverages (juices with pulp, fruit purees, syrups, concentrates);
• fruit and vegetable purees, pastes, fillers;
• fats and oils (vegetable oils, animal fats, margarine).

Design features

ONB-SP pumps have a gearless design, which reduces cost and simplifies maintenance. The operating speed of the rotor is achieved by direct drive from an electric motor (750-1500 rpm). The performance is adjusted by a frequency converter.

At the customer’s request, the pumps are equipped with a milk nut, a coupling, a flange, an inlet neck or a retaining screw to improve the filling of the working chamber with viscous products. It can be made in horizontal (ONB-SP-H) or vertical (ONB-SP-V) versions.

Execution for the food industry

• Hygienic: smooth surfaces of contact parts, absence of stagnant zones, possibility of polishing. Quick-release connections (Clamp type) for quick cleaning and inspection;
• Safe materials: The parts in contact with the product comply with the requirements of the FDA and EC 1935/2004. Stators made of food grade elastomers (EPDM, NBR, FKM), rotors and housings made of stainless steel AISI 304 (12X18H10T) or AISI 316;
• Gentle pumping: The gerotor steam ensures smooth feeding while maintaining the structure and viscosity of the product.;
• Working with viscous media: effective work with products with a viscosity of up to 10,000 SDRs or more.

Advantages of ONV-SP pumps

• own production in Russia — full quality control and delivery time;
• adaptation to a specific task — selection or modification for line parameters;
• reliable self—made gerotor pair – long service life and stable operation;
• easy maintenance — modular design, easy access to components, availability of spare parts in stock;
• economic efficiency — energy efficiency, long service interval, low maintenance cost.
