The QBY type engineering plastic diaphragm air pump is an air-driven pump, particularly suitable for the pressure supply units of various solid-liquid separation equipment. Its working principle is based on compressed air drive, which achieves the suction and discharge of liquid through the reciprocating movement of the diaphragm. Specifically, there are two symmetrical working chambers inside the pump body, each containing an elastic diaphragm. Connecting rods link the two diaphragms together. When compressed air enters the gas distribution valve, it drives the diaphragm to move, thereby forcing the liquid into and out of the pump body.
Key Features
No shaft seal, no leakage: The QBY type pneumatic diaphragm pump has no rotating parts, ensuring no leakage, making it particularly suitable for transporting toxic, volatile, or corrosive media, guaranteeing safe operation._
Strong self-priming ability: This pump does not require priming water, with a suction lift of up to 7 meters, and can run dry for extended periods without damaging the pump body.
Versatile: Capable of transporting particulate, high viscosity (up to 10,000 centipoise), volatile, and corrosive media with minimal wear on the pump.
Safe and Reliable: No power supply needed, ideal for use in flammable and explosive environments. It features self-protection, automatically shuts down upon overload, and restarts automatically once the normal load is restored._
Simple structure and easy maintenance: The pump features a simple design with minimal wear parts, making installation and maintenance a breeze.
Application Scenario
The QBY type pneumatic diaphragm pump is widely used in various applications involving corrosive liquids, liquids with particles, high viscosity, volatile, flammable, explosive, and highly toxic substances. For instance, it can fully extract liquids such as ceramic glaze slurry, fruit puree, adhesives, oil recovery from oil tankers, and temporary tank transfers. Additionally, it is suitable for transporting viscous materials like peanut butter, sauerkraut, mashed potatoes, cured sausages, chocolate, hops, and syrups.
