Procurement and selection of deep well pumps
The deep well pump is a vertical centrifugal pump. The deep well pump can lift the water up in the well. With the drop of the underground water level, the use of deep well pumps is more extensive than the general use of centrifugal pumps. However, due to improper selection of models, some users may …...Read more -

Why does the water pump produce cavitation
Cavitation is when the liquid (which can be water, oil, etc.) in the flow channel (which can be a pump, a water turbine, a river, a valve, a propeller, or even an animal’s blood vessel) drops a critical pressure (generally close to the vaporization pressure), the gas core in the water It is a general …...Read more -
Calculation formula of pump flow and head
1. Water pump flow calculation formula: What is the pump flow calculation formula? In the process of pump use, it is often necessary to calculate the pump flow, but many people don’t know much about the pump flow calculation formula. Let’s take submersible pumps and gear pumps as examples to introduce the pump flow calculation …...Read more -
Principles and steps of pump selection
Section 1: Selection Principle The pump is a wide range of general-purpose mechanical equipment, which is widely used in various departments of petroleum, chemical industry, electric power metallurgy, mining, ship selection, light industry, agriculture, civil and national defense. In recent years, the Chinese pump industry has designed and developed many high-efficiency and energy-saving products, such …...Read more -
Precautions for installation of self-priming pumps
The working principle of the self-priming pump is: fill the pump casing with water before starting the pump (or there is water in the pump casing itself). After starting, the impeller rotates at a high speed to make the water in the impeller channel flow to the volute. At this time, a vacuum is formed …...Read more -
The development history of multistage pumps
Worthington in the United States invented a piston pump in which the pump cylinder and the steam cylinder were opposed, and the steam directly acted on the piston pump, marking the formation of the modern piston pump. The 19th century was the climax of the development of piston pumps, and they were used in hydraulic …...Read more -
How to select the pump
1. The principle of pump selection 1. Make the type and performance of the selected pump meet the requirements of the device flow, head, pressure, temperature, cavitation flow, suction and other process parameters. 2. Must meet the requirements of media characteristics. For pumps that transport flammable, explosive, toxic, or precious media, reliable shaft seals or …...Read more -
