Chemical pumps are specialized industrial pump equipment designed for the transportation of corrosive, high-temperature, low-temperature, or special chemical media. They have specific requirements in terms of material, sealing, and structural design, enabling the safe conveyance of corrosive liquids such as acids, alkalis, and salt solutions. The material selection for chemical pumps must be determined based on the specific chemical medium, concentration, and temperature Classification by Material: Stainless steel chemical pumps: Widely used in industries such as petroleum, chemical, and pharmaceutical sectors for conveying alkaline corrosive media, commonly made from 304 and 316L stainless steel. Fluoroplastic chemical pumps: Used for conveying any acidic, alkaline, or corrosive media, offering the best corrosion resistance. Cast iron chemical pump: Used for industrial and urban water supply and drainage, conveying clean water or liquids with physical and chemical properties similar to clean water Classification by Structure: Centrifugal pump: the most common type, including single-stage single-suction and multistage centrifugal pumps, with the IH type being a typical representative. Positive displacement pumps: such as reciprocating pumps, gear pumps, and screw pumps, suitable for high-viscosity media. Magnetic drive pump: leak-free design, suitable for flammable, explosive, and toxic media. ‌‌ Classification by Purpose: Process flow pumps: feed pumps, reflux pumps, circulation pumps, etc. Auxiliary purpose pumps: lubricating oil pumps, sealing oil pumps, etc. Pipeline transfer pumps: pumps for oil pipelines, pumps for loading and unloading vehicles, etc Primary Application Areas: Petrochemical: oil refineries, petroleum chemical industry, coal processing projects. Pharmaceutical and Food: Transporting raw material solutions and finished pharmaceutical solutions, which must comply with hygiene standards. Environmental Water Treatment: Industrial wastewater treatment, urban water supply pipelines. Metallurgy and Power: Non-ferrous metal smelting, power plants, seawater desalination.

magnetic drive pump is an industrial pump that utilizes magnetic coupling to transmit power and achieve fully sealed, leak-free transportation, making it particularly suitable for handling toxic, flammable, or highly corrosive liquids. It operates by driving the impeller rotation through the magnetic interaction between internal and external magnetic rotors, completely eliminating the physical shaft seal of traditional pumps and fundamentally eliminating the risk of medium leakage The core of the magnetic drive pump lies in the "magnetic coupler," which transmits the rotational power of the motor to the pump shaft without contact. The specific structure includes the following key components: Magnetic Coupling System: Consists of an outer magnetic rotor (connected to the motor) and an inner magnetic rotor (connected to the impeller), completely separated by an isolation sleeve in the middle. Isolation Sleeve: This is the key component for achieving zero leakage, typically made of stainless steel, titanium alloy, or high-performance plastic, ensuring the medium is sealed within the pump chamber. Magnetic steel material: High-performance magnetic pumps often use neodymium iron boron or samarium cobalt permanent magnet materials. Samarium cobalt magnetic steel has better temperature resistance and is suitable for high-temperature working conditions. Cooling and Lubrication: During pump operation, 2%-3% of the conveyed medium's flow rate must be utilized to cool the bearing and magnetic rotor areas, hence no idling is permitted. Structural Forms: Common configurations include horizontal, vertical, and high- temperature resistant types. Some high-temperature models are equipped with water cooling devices or double-layer insulation structures to prevent heat conduction to the motor and avoid demagnetization. Performance range Normal temperature pump is used for fluids with temperature from -30 ℃ to 120 ℃. High temperature pump is up to 350 ℃ or even 400 ℃ Pressure and flow rate: The design pressure is usually 1.6-6.4MPa, and the flow rate range can be from 2m ³/h to 1400m ³/h Viscosity of fluids: The viscosity of the conveying medium is generally not greater than 30 × 10 ⁻⁶ m ²/s, and it must not contain ferromagnetic impurities or hard particles

A submersible pump is a water extraction device that can operate entirely submerged in water. It integrates the motor and water pump, allowing direct submersion without the need for a pump house, making installation particularly convenient. It is widely used in scenarios such as farmland irrigation, deep well water extraction, mine drainage, and household water supply The clean water submersible pump is suitable for pumping clean water, such as well water or lake water, but should not be used for water with high sediment content, as it may easily burn out the motor. The sewage submersible pump can draw water containing impurities and silt, with its impeller featuring a cutting function to shred debris and prevent clogging. Hot water submersible pumps are specifically designed for extracting geothermal and hot spring water, with a working temperature range of 5-125°C, and some models can withstand high temperatures up to 146°C. Deep well submersible pumps are used for water extraction from vertical well pipes, featuring high head and suitability for lifting water from depths of several tens to hundreds of meters. The low-power submersible pump is compact in size, comparable to a soda can, and suitable for aquariums, small fountains, and garden irrigation.

pipeline pump is a centrifugal pump directly installed on the pipeline, with its inlet and outlet aligned in the same straight line. It is used in series like a valve and primarily serves to boost and transport liquids. 1.Pipeline pumps are single-suction single-stage or multi-stage centrifugal pumps with vertical or horizontal configurations. They feature identical inlet and outlet ports aligned on the same central axis, allowing direct flange connection and installation in the pipeline without requiring additional suction piping. 2. Relationship with Centrifugal Pumps: The pipeline pump is a special type of centrifugal pump, operating on the same principle (motor drives the impeller to rotate and generate centrifugal force for pressurization). The difference lies in its more compact structure, coaxial inlet and outlet design that eliminates the need for a suction bend, and simpler pipeline layout. Core working principle: The electric motor drives the pump shaft and impeller to rotate at high speed. Liquid is drawn into the pump body and flows axially along the impeller, where centrifugal force pushes the liquid toward the outlet, increasing pressure to overcome pipeline resistance, enabling long-distance or elevated transport Type and application Classification by conveyed medium: ISG-type water pump: Suitable for conveying domestic water and circulating water at normal temperatures, with a medium temperature range of -20°C to 80°C. Commonly used in central air conditioning systems and factory circulating water systems. Hot water pump (IRG type): Used for conveying boiler hot water and underfloor heating circulation water, with a medium temperature range of 80°C to 140°C. The pump body is equipped with heat dissipation fins, and the mechanical seal is resistant to high temperatures. Oil Pump (YG Type): Suitable for transporting gasoline, kerosene, and diesel with a medium temperature range of -20°C to 120°C. Equipped with explosion-proof motors, it is used in the petroleum industry and oil depot pressurization. Chemical Pump (IHG Type): 316L stainless steel pump body, suitable for conveying mild acid and alkali chemical media, corrosion-resistant. Classified by installation form: Vertical pipeline pump: The motor is vertically upward and occupies a small area. It is installed on a horizontal pipeline and needs to be removed during maintenance. Horizontal pipeline pump: The motor is arranged horizontally for easy maintenance, and the mechanical seal is easy to replace in the later stage. It occupies a large area and is preferred for large power applications Typical application scenarios: High rise building pressurized water supply, central air conditioning cooling/chilled water circulation, boiler hot water circulation, fire pressurization, industrial process liquid transportation, hotel and shopping mall tap water pressurization.
