Qby PVDF Diaphragm Pump Handles Liquid with Tiny Solid Impurity Particles

Product Description

Overview

The QBY PVDF series pneumatic diaphragm pump is a highly versatile air-powered positive displacement pump engineered for the safe and efficient transfer of challenging fluids. Built with Polyvinylidene Fluoride for all wetted components, it delivers exceptional chemical resistance, making it the ideal solution for handling corrosive, abrasive, and sensitive media that traditional pumps cannot reliably process.
 
Powered exclusively by compressed air, this pump eliminates the need for electrical drives, offering intrinsic safety for use in explosive, flammable, or hazardous industrial environments. Its unique reciprocating diaphragm mechanism allows it to handle liquids with high solid content, large particle sizes, and high viscosities, while maintaining a completely leak-free operation due to the absence of rotating shafts or mechanical seals. It is capable of pumping a wide range of fluids, from highly corrosive acids and alkalis to viscous pastes, slurries, and even volatile or toxic substances, making it an indispensable tool across multiple industries.

Key Features

Superior Corrosion Resistance PVDF Material: All wetted parts, including the pump body, diaphragms, and check valves, are constructed from PVDF Polyvinylidene Fluoride. This advanced thermoplastic polymer offers outstanding resistance to a vast spectrum of aggressive chemicals, including strong acids, strong alkalis, organic solvents, and oxidizing agents. It resists degradation, swelling, and cracking, ensuring the pump remains robust and reliable even in continuous contact with highly corrosive fluids, significantly extending its operational lifespan compared to stainless steel or plastic alternatives.
 
Intrinsically Safe & Explosion-Proof Design: As a pneumatically driven device, the pump operates without any electrical components. This inherent design makes it intrinsically safe for installation and operation in hazardous areas, where flammable gases, vapors, or dusts are present. It eliminates the risk of spark ignition, making it the preferred choice for chemical plants, refineries, pharmaceutical facilities, and other high-risk industrial environments.
 
Zero Leakage & Environmentally Friendly Operation: The pump features a sealless design with no rotating shafts or dynamic seals that can wear out or fail. The reciprocating diaphragm acts as the primary sealing element, completely isolating the fluid from the external environment. This guarantees zero leakage of hazardous, toxic, or valuable fluids, preventing environmental contamination, ensuring workplace safety, and eliminating the costs associated with fluid loss and cleanup.
 
Exceptional Self-Priming & Suction Capability: The QBY PVDF pump boasts a powerful self-priming function, capable of drawing fluid from depths of up to 7 meters without the need for pre-priming or a foot valve. This capability is invaluable for applications where the fluid source is located below the pump, such as underground tanks, sumps, or wells, and it ensures quick and reliable startup even after prolonged periods of inactivity.

Application

1. Food industry: Peanut butter, pickles, mashed potatoes, jam, apple pulp, chocolate, syrup, etc.

2. Chemical industry: Paints, gums, pigments, adhesives, glues, strong acids, strong alkalis, corrosive oils, and mud.

3. Ceramic industry: Ceramic slurry, brick, and pottery glaze.

4. Mining & construction: Mine water, tunnel drainage, mineral processing slag, cement grout, and mortar.

5. Environmental & sewage: Various types of sewage, oil tank cleaning, and warehouse sewage.

6. Special applications: Highly toxic, flammable, volatile liquids, high-temperature liquids (up to 150°C), and as a front-stage pressure transmitter for solid-liquid separation equipment.
