What is a corrosion-resistant self-priming pump? What is the working principle of a corrosion-resistant self-priming pump?A centrifugal pump that can automatically pump water up without filling the suction pipe with water is called a corrosion-resistant self-priming pump.The working principle of the corrosion-resistant self-priming pump is: a vacuum is formed at the inlet of the pump, the water inlet check valve is opened, the air sucked into the water inlet pipe enters the pump, and in the impeller channel, the air and the radial return hole (or water in the return pipe). Together, they flow along the channel volute and enter the separation chamber. In the separation chamber, the air is separated from the liquid, and the liquid returns to the impeller. This cycle is repeated until the air...

Coaxial self-priming acid and alkali resistant pump KB series1. Unique shaft seal design - the built-in type adopts TeflonBellowSeal self-cooling design.2. Self-priming design - the self-priming ability is particularly strong, and the self-priming type can reach 20ft. It is also designed with a check valve to prevent the backflow of liquid in the pump.3. Acid and alkali resistance, strong corrosion resistance, mainly made of FRPP and PVDF (Teflon).4. A foot valve should be installed at the inlet to prevent the inhalation of foreign matter, and a check valve should be installed at the outlet. In order to prevent the phenomenon of instantaneous backflow during shutdown, which will cause damage to the pump body.Coaxial centrifugal acid and alkali resistant pump KG series1. Unique shaft seal d...

Many customers don't know how to choose the type of acid and alkali resistant pump from Yibao brand, so today we will talk with you about pump selection.What issues should be considered in pump selection? First of all, what we should consider is the medium of the medicinal solution. This is related to the chemical properties of the liquid medicine. The stronger the acidity and alkalinity of the liquid medicine, the higher the requirement for the acid and alkali resistance of the pump body material. Of course, we can't just rely on the concentration of the liquid medicine to choose the pump material, but also consider the temperature of the liquid medicine, the hardness of the solid particles in the liquid, and other issues to comprehensively determine which material to choose for t...

There are more and more users of Yibao brand acid and alkali resistant pumps. Today we will popularize the installation and use precautions of our Yibao brand idling vertical acid and alkali resistant pumps.First of all, let me introduce our Yibao brand acid and alkali resistant vertical pump. The main series of Yibao vertical pumps are: KD series, KDS series, KPT series, KP series, KDV series, etc. The pumps of these series are made of chemical-resistant materials-CFRPP, FRPP and PVDF, corrosion-resistant powerful. Of course, if you need to use it in a special environment, please contact our technical staff to select the model for you.The following is the operation guide:1. Before using the pump, pay attention to whether the fluid type, viscosity, temperature, specific gravity, solid part...

Chemical pumps are the most used rotating equipment in petrochemical production plants. They transport various liquid media such as crude oil, refined oil, chemical raw materials, intermediate products and finished products to other places like the human heart transports blood.my country's petrochemical industry will have a great development during the "Tenth Five-Year Plan" period, and the production technology and scale will be on par with the international level. The two major groups, Sinopec and PetroChina, invest nearly 100 billion yuan each year, and the demand for petrochemical equipment will be huge. of.According to statistics, a medium-sized oil refinery has more than 1,000 pumps, of which centrifugal pumps account for 83%, reciprocating pumps account for 6%, gear ...
