Screw Pump Single Screw Pump Screw Pump for Food Industry

Product Overview
G Single Screw Pumps is an enclosed screw pump with inner gearing, a kind of rotor positive-displacement pump. As this kind of pump is characterized by being adaptable for the medium, stable flow, good suction performance and small pressure pulsation, it can transfer very viscous media or those containing hard suspended or solid grains or fiber apart from various flowing media. Besides, it boasts good adjusting performance, wide range and high efficiency. Therefore, it is widely applied in various industries like environmental protection, shipping, petroleum, pharmacy, household chemical, food, brewage, construction, mining, chemistry, printing, paper making, power plants and boilers. The pump fewer parts, compact structure, small size, maintenance is simple, the rotor and the stator is the pump wearing parts, simple structure, easy assembly and disassembly.

Working Principle
The single screw pump is a kind of rotary positive-displacement pump with inner gearing. Its main working parts include eccentric screw (rotor) and fixed bush (stator). Due to special geometric
Shapes of the rotor and the stator, several separate seal cavities come into being respectively. The rotation of the rotor drives the transfer of media in all seal cavities from the suction end to the
Extrusion end continuously at a constant speed with the same volume. By right of these characteristics, the single screw pump is especially suitable for the following working conditions:
1. Transfer of very viscous media;
2. Transfer of media containing solid grains or fiber;
3. Requiring continuous operation, stable pressure and no regular pressure fluctuation;
4. Requiring small agitation and no damages to the inherent structure of transferred media;
5. Low noise.
Application Scope
As a kind of universal pump, the flow of the single-screw pump can be adjusted by changing the running speed and its outlet pressure can increase along with the rise of pump stage with 0.6Mpa up per stage. It is widely applied in the following scope and industries:
1. Environmental protection: Transfer of industrial and domestic sewage and sludge and turbid water containing solid grains and short fiber, esp. Applicable for oil-water separator, plate-and-frame filter press, etc.;
2. Shipping industry: Washing of tanker bottom and transfer of such media as oily water, oil residue, and oily sewage;
3. Petroleum industry: Transfer of crude oil, mixture of crude oil and water as well as mixture of coal field gas and water, and pouring polymer into the stratum, thus reducing costs of mechanical extraction of oil and coal field gas and increase the recovery ratio of oil field;
4. Pharmacy and household chemical: Transfer of various viscous slurry, emulsion and cream cosmetics;
5. Food and can industry: Transfer of various viscous amylum, edible oil, honey, syrup, juice, cream, scrappy fish and meat
