Vortex pump principle Vortex pump principle is the liquid in the runner and impeller vortex movement back and forth, resulting in a higher pressure head. Vortex Pump Features Comparison Vortex Pumps Compared to Centrifugal Pumps Smaller Flows High Pressure Engineering Uses (Compared to Single-Stage Centrifugal Pumps) Pumps have supercharged parts with no mechanical contact and friction and are therefore particularly stable and durable. If you use a larger diameter centrifugal impeller pump, in order to prevent the pressure fluctuations, voids and liquid temperature rise and other phenomena, we have to set the flow to a minimum, to meet the required flow after bypass with the excess air back to the original Department. This will not only increase the initial investment, high-power motors and increased power consumption, operating costs increased significantly. In contrast, the vortex pump flow pressure is high, when the valve is small, the flow rate decreases, the liquid is also very stable. Therefore, as long as the pump to ensure that not overheating and motor rated power operation, the flow can be set free, in all aspects can greatly reduce costs. Filtration Applications (Compared to Multistage Centrifugal Pumps) For high-pressure membrane filtration applications, it is ideal to use a pump that has no pulsation and maintains a high level of quantitation regardless of its nature. When a multistage centrifugal pump is used for this purpose, an excessive flow rate may occur when using a new filter membrane. However, when a pump of a proper flow rate is used, the flow rate will be insufficient due to a slight clogging of the filter membrane. Vortex pump flow at the pressure of the open point and the highest point of little change, the most suitable for this purpose. Harsh Operating Conditions (Compared to Multistage Centrifugal Pumps) Vortex pumps are small in size, simple in structure, and have few parts. They operate freely under harsh conditions requiring high pressure with intermittent operation, water hammer, and repeated negative pressure. In contrast, centrifugal pumps require pressure from multiple stages of impellers and therefore become complex, have large rotational inertia and increase the risk of accidents or malfunctions. Sampling of various liquids (compared to self-priming centrifugal pumps) Water quality management and sampling in various processes are required. Vortex pump has a strong self-suction, 8 meters away from the liquid can inhale the liquid. And its volume smaller than the centrifugal pump, can quickly drain the residual liquid, greatly reducing the sampling time and ensure the accuracy of sampling. Vortex pump compared with gear pump suction from the underground tank Pressure delivery low viscosity liquid vortex pump is best suited for this need self-priming performance and high pressure purposes. Not only does it have strong self-priming ability, it also has strong durability even when liquids containing fine foreign particles are transferred because there is no mechanical contact and metal friction in the pump. The gear pump is basically not suitable for low viscosity liquids, often abnormal sound, performance degradation, stuck foreign body and other failures. High Temperature Waste Oil Spray Combustion Industrial waste, such as used oil or solvent, which has a low viscosity at high temperatures, needs to be spray-incinerated. However, this allows the liquid to be easily vaporized at a high temperature, and due to the liquid containing a small amount of foreign matter, the use of a gear pump causes premature performance degradation, foreign matter entrapment, and noise. Under the same conditions, the vortex pump has long service life, low noise and reliable performance because of its low NPSH structure and no metal contact and friction in the pump. Vortex Pump Compared to Piston Pumps High Accuracy, High Pressure Testing Uses Low noise, pulsation-free, vibration-free vortex pumps are an indispensable source of pressure in the development and performance testing of valves, nozzles, automation equipment, and more. And it booster department has no mechanical contact and friction, durability, do not need regular replacement parts. The plunger pump, even if the assembly of a large pressure accumulator can not completely eliminate the pulsation, can not guarantee accurate testing and testing, and in the maintenance of a waste of time and money.
