Vertical centrifugal pump selection method： The main control parameters for the selection of vertical centrifugal pumps are the flow rate Q, head H, efficiency η, power, speed n, working pressure, required cavitation margin (NPSH), etc. of the water vertical centrifugal pump.To select a vertical centrifugal pump reasonably, it is necessary to comprehensively consider the comprehensive […]

What is a magnetic drive pump? The magnetic pump is a branch of the water pump field. It is a new product that applies the working principle of a permanent magnetic coupling to a centrifugal pump. The magnetic pump consists of three parts: a pump, a magnetic transmission, and a motor. The magnetic transmission of […]

The selection of submersible pumps should be based on the process flow, water supply and drainage requirements, and should be considered from five aspects: liquid delivery volume, device head, liquid properties, pipeline layout, and operating conditions. Let’s take a look at the specific submersible pump selection method and the precautions for using submersible pumps. 5 […]

A screw pump is a rotary pump that relies on the volume change and movement of the meshing space formed by the pump body and the screw to transport liquid or increase its pressure. Screw pumps are divided into single screw pumps, double screw pumps and three screw pumps according to the number of screws. […]

Both rotor pumps and screw pumps are volumetric pumps, and their performance is basically similar – both can smoothly convey high-viscosity materials and have high conveying pressures. So, what are the differences between rotor pumps and screw pumps? Different internal structure. The rotor pump conveys materials by rotating the two rotors in the opposite direction […]

Diesel engine water pumps are widely used in various situations. Here are several main usage scenarios: Industrial field: Diesel engine water pumps are a commonly used equipment in the industrial field, used to realize the circulation, transportation, and discharge of water in industrial production. For example, in chemical plants, petrochemicals, pharmaceuticals, textiles and other industries, […]

A Dosing pump is a special volumetric pump that can meet the needs of various strict process flows. The flow rate can be adjusted steplessly within the range of 0-100% and is used to transport liquids (especially corrosive liquids). A Dosing pump is also called a quantitative pump or a proportional pump. A Dosing pump […]

The starting of a pump or pump group is a light load start for the prime mover, and generally there will be no problems when starting. However, for some large units, due to the large inertia of the unit, it is difficult to start, and there is a large starting current when starting. If you […]
