Through the movement of components such as rotors, impellers, or pistons inside the pump, the volume of the pump cavity changes periodically. Each change enables the intake and discharge of a certain amount of sauce, ensuring stable flow and precise control. Pumps like cam - rotor pumps and screw pumps belong to the positive - displacement pump category.
The motor drives the impeller to rotate, generating centrifugal force. This force causes the sauce to be flung from the center of the impeller to the outer edge of the impeller, creating a low - pressure area at the center of the impeller. As a result, the sauce is sucked in from the suction port and discharged from the discharge port. Some centrifugal pumps are applied in this way.
Made of materials such as stainless steel that are corrosion - resistant, wear - resistant, and meet hygiene standards, the pump has a smooth surface with no hard - to - clean corners. It is easy to clean and disinfect, ensuring that the conveyed sauce is not contaminated.
Equipped with accurate flow and pressure control devices, it can accurately adjust the conveying volume and pressure of the sauce according to production requirements, meeting the needs of different production processes.
Typically, it uses high - efficiency motors and optimized designs to improve energy utilization efficiency, reduce energy consumption, and save production costs.
By selecting high - quality materials and advanced manufacturing processes, the pump has strong corrosion resistance, wear resistance, and fatigue resistance. It can operate stably under long - term high - load working conditions and has a long service life.
It consists of two synchronously rotating cam rotors. A sealed chamber is formed between the rotors and the pump casing. As the rotors rotate, the volume of the chamber changes, achieving the intake and discharge of the sauce. It has the characteristics of strong self - priming ability, smooth conveyance, and can transport high - viscosity sauces and sauces containing particles. It is widely used in industries such as food, beverage, and pharmaceuticals.
It relies on the rotational movement of the screw to convey the sauce. A sealed chamber is formed between the screw and the pump body. When the screw rotates, the chamber moves axially, transporting the sauce from the inlet to the outlet. It can be divided into single - screw pumps, double - screw pumps, and triple - screw pumps. The single - screw pump is suitable for transporting high - viscosity sauces with low shear force, while double - screw pumps and triple - screw pumps can transport sauces with relatively high viscosity and containing certain particles.
It uses the pressure difference of air to push the piston to move up and down, driving the opening and closing of the guiding piston to achieve material lifting and feeding. By adjusting the flow rate and pressure of the working gas, the operating frequency of the pump and the feeding flow rate can be controlled. It has the advantages of explosion - proof, corrosion - resistant, anti - sedimentation, low noise, and energy - saving, and is suitable for high - viscosity slurries and occasions with explosion - proof requirements.
It has a simple structure, reliable operation, and a large flow rate. It transports the sauce by generating centrifugal force through the rotation of the impeller. However, its conveying efficiency for high - viscosity sauces is relatively low. It is generally suitable for sauces with low viscosity and good fluidity. It is also applied in some food and beverage industries with high hygiene requirements.
It is used to transport various sauces, such as ketchup, chili sauce, salad dressing, jam, honey, syrup, etc., and can also be used for the quantitative transportation of food additives and seasonings.
It can transport viscous liquids such as ointments, liquid medicines, and pharmaceutical intermediates, meeting the process requirements of metering, filling, and ingredient - mixing in the pharmaceutical manufacturing process.
It is suitable for the transportation and filling of cosmetic raw materials and finished products such as lotions, creams, gels, and lipsticks, ensuring product quality and production efficiency.
It can transport various viscous fluids such as chemical slurries, coatings, inks, glues, and resins, playing an important role in the raw material transportation, reactor feeding, and product packaging in chemical production.
