Chemical Pumps

(Practical dry goods that ordinary people can understand) Why is your chemical pump always "unsuitable"? The high-performance "centrifugal pump" bought for 150,000 yuan leaked and stopped working in less than 3 months? The repair cost was 80,000 yuan. What's the problem? Is it really the quality of the manufacturer? It's not necessarily the case. It is very likely that the problem is in the selection process. The parameters of the chemical pump and the actual working conditions are "incompatible". Choosing the wrong model of chemical pump will waste money at best and cause safety accidents at worst!     Misunderstanding 1: Only look at the flow and head, and ignore everything else       Many users often rely on experience to estimate the flow and head of chemical pumps, but if they do not fully consider the actual situation, it may affect the matching of pump performance. For example, in the case of high-viscosity liquids, the starting torque requirement is high. If the power is not adjusted in time during selection, it may cause motor overload or pump damage.     When choosing a chemical pump, you must ask these questions: - Medium composition (solid content? Corrosive? Flammable and explosive? Acid, alkali, salt, toxic and sticky, ask everything) - Working temperature (normal temperature? High temperature? Low temperature? Low temperature needs insulation, high temperature prevents cavitation) - Flow rate and head (through actual measurement or calculation with professional software, ensure that the performance curve of the pump matches the actual working conditions) - Running time (continuous operation or intermittent use?) - Installation environment (indoor? Outdoor? Explosion-proof area?)     Misunderstanding 2: Not fully considering pipeline pressure drop and other technical parameters:     Because of the mismatch of pipelines, the actual performance of chemical pumps is not as expected. In addition to the chemical pumps themselves, you should also pay attention to the length, diameter, pressure drop, etc. of the pipeline when selecting to ensure a comprehensive selection.     Misunderstanding 3: Ignoring daily maintenance costs         You will understand after doing the math:       While considering the initial investment, you also need to consider the later maintenance and operation costs of the equipment. You need to comprehensively evaluate the costs before and after, and choose a chemical pump with high cost performance.     Misunderstanding 4: Not paying attention to the details of chemical pump selection       The last thing to consider is the energy consumption requirements under environmental protection. Exceeding the energy consumption standard is not allowed in some areas, so the product must meet the latest GB 19762 energy efficiency standard. Secondly, when the chemical pump is repaired, can the manufacturer provide a 10-year spare parts supply commitment? If there is a need for transformation, can it adapt to the factory's intelligent transformation needs (such as adding sensors)? How long is the warranty period? How long is the delivery period? What should I do if the performance does not meet the standard? These questions must be confirmed with the manufacturer one by one     According to the above methods, the selection misunderstandings of chemical pumps can basically be avoided.
