Product Description
Q1: What kind of pump is the Stainless Steel Pneumatic Diaphragm Pump, and what is its main design purpose?
A1: It is a high-performance positive displacement pump specifically engineered for tough industrial fluid-handling tasks. Its main design purpose is to combine corrosion resistance, pneumatic reliability, and versatile media compatibility, so it can effectively handle various complex fluid transportation needs in industrial environments.
Q2: Why is premium stainless steel (304 or 316 grade) used in its construction, and what benefits does this bring?
A2: Premium stainless steel (304 or 316 grade) is used because its wetted parts, including the pump head, valves, and diaphragm, need to resist corrosive substances. This material delivers exceptional resistance to corrosive liquids like dilute acids, alkalis, and chemical solvents, as well as rust and oxidation. The benefit is that it ensures fluid purity and enhances equipment durability, making the pump ideal for applications where these two factors are critical, such as chemical processing, pharmaceutical production, and wastewater treatment.
Q3: What power source does this pump use, and why is this power source chosen?
A3: It is powered by compressed air instead of electric motors. This power source is chosen because it eliminates the risk of sparks. In explosive or flammable environments like oil refineries and paint factories, using compressed air ensures the pump operates safely without triggering potential hazards.
Q4: How does its diaphragm-driven working principle work, and what types of media can it handle?
A4: Its diaphragm-driven working principle involves the alternating expansion and contraction of the pump chamber. Compressed air pushes the diaphragm to displace fluid, and a check valve system ensures one-way flow. This principle enables the pump to handle a wide range of media, not only clean liquids but also viscous fluids, slurries with small solids (up to 3mm), and shear-sensitive media like emulsions and resins, without causing damage to the media.
Q5: What are the key advantages of this pump, and in which specific industrial scenarios is it widely used?
A5: Its key advantages include self-priming capability (with a suction lift up to 8 meters), dry-run resistance (no damage from temporary fluid shortage), and easy maintenance (simple diaphragm replacement without disassembling the entire pipeline). It is widely used in various industrial scenarios, such as chemical dosing, paint transfer, food-grade liquid handling (with sanitary stainless steel options), and offshore or remote sites where electric power is limited.
