Electric Diaphragm Pump for Sale A diaphragm pump is a type of positive displacement pump that uses a flexible diaphragm to move fluid. It is a versatile and reliable pump that is widely used in a variety of industries, including chemical processing, pharmaceuticals, food and beverage, and many others. Diaphragm pumps are self-priming and can handle a wide range of fluids, including corrosive and viscous liquids, slurries, and even solids. They are designed to prevent contamination of the fluid being pumped and can run dry without damage to the pump. The flow rate of a diaphragm pump can be easily adjusted by changing the stroke length or the speed of the motor, making it suitable for a variety of applications. Overall, a diaphragm pump is a reliable, efficient, and versatile pump that is widely used in many industries for its ability to handle a variety of fluids and its ease of use and maintenance.

Ferrite-Pearlite ductile iron is a type of ductile iron known for its high strength and toughness, with its primary microstructure consisting of ferrite and pearlite. This material exhibits excellent wear resistance and corrosion resistance, as well as high fracture toughness and ductility. It finds wide applications in various industries: In the mechanical manufacturing sector: Manufacturing components such as machine tool bodies, mechanical parts, reducers, and hydraulic cylinder sleeves. In the automotive manufacturing sector: Manufacturing components such as cylinder blocks, cylinder head covers, and crankshafts for automotive engines. In the energy sector: Manufacturing components such as turbochargers, centrifugal pumps, and gears. With continuous technological advancements, it is believed that Ferrite-Pearlite ductile iron will continue to find increasingly widespread applications in the future.
High-silicon molybdenum ductile iron (5% silicon content) finds extensive applications in high-temperature castings for automotive engines, particularly in exhaust systems (e.g., exhaust pipes, turbocharger housings, valve bodies, valve discs, etc.). This is primarily due to its excellent properties including high-temperature resistance, thermal fatigue performance, outstanding oxidation resistance, and good high-temperature creep resistance. Our company has now developed precision-cast high-silicon molybdenum ductile iron valve discs, valve bodies, and other castings, featuring high dimensional accuracy, delicate appearance, and excellent performance, which have been utilized in exhaust systems for heavy-duty trucks.

Product Application: Ceramic salt cores are primarily used in the casting process of liquid forging aluminum alloy pistons. By forming cavities inside the piston, ceramic salt cores help achieve an internal cooling structure for the piston. Features: High Strength: By adding ceramic additives, ceramic salt cores achieve high strength, enhancing their ability to withstand high temperatures and pressures of aluminum liquid. High Density: Multiple granulation techniques are employed to achieve high density in ceramic salt cores, contributing to the overall quality of the castings. Low Linear Expansion Coefficient: Through innovative sintering techniques, ceramic salt cores achieve a low linear expansion coefficient, reducing the impact of thermal expansion on aluminum alloy pistons. Ceramic salt cores are typically used in the casting of liquid forging aluminum alloy pistons. Compared to traditional salt cores, ceramic salt cores meet the requirements of high-pressure casting processes for salt cores by increasing ceramic additives, using multiple granulation techniques, and innovative sintering techniques to achieve high strength, high density, and low linear expansion coefficient performance.
Product Application: Forming of complex cavities inside aluminum castings. Features: 1. Compared to ring-shaped piston salt cores, irregular-shaped salt cores, through optimized process upgrades, can produce salt core products of any shape. 2. Irregular-shaped salt cores have higher strength than ordinary piston salt cores. 3. Compared to sand cores and ceramic cores, they are easier to clean and have better surface finish. 4. Widely applicable in the forming of cavities in aluminum alloy products. (1) New salt cores applied to all lightweight castings' internal cavities. Advantages: Currently, most lightweight castings use resin sand cores to form complex internal cavities. During later cleaning, sand sticking may occur locally, making it difficult to clean the internal cavities, which is an unavoidable technical problem. The development of new salt cores can easily solve the problem of difficult sand cleaning in castings. Salt dissolves in water, and only water flushing is needed to meet the technical requirements for removing internal core sand. The use of salt cores in the piston field is already a very mature technology. The new salt core is an extension of piston salt core technology. (2) New salt cores applied to difficult-to-machine areas of injection-molded products. Advantages: For products with difficult-to-machine areas in the later stages of injection molding, new salt cores can be used to directly form the parts that need to be machined later. Place the salt core in the mold before injection molding. This eliminates the technical difficulties of difficult machining in the later stages.

Type DO is the most common form that uses an O-Ring as a secondary sealing element Type DO consist of two identical metal seal rings mounted in two separate housings face-to-face on a lapped seal face. The metal rings are centered within their housings by an elastomer element. One half of the Mechanical Face Seal remains static in the housing, while the other half rotates with its counter face.
