I. Product Overview

The Shanglun QBK perfluorinated pneumatic diaphragm pump is a high-end fluid transfer device manufactured from perfluorinated materials, specifically designed for handling highly corrosive media. Constructed from materials such as polytetrafluoroethylene (PTFE), it offers exceptional corrosion resistance, enabling the safe transfer of highly corrosive liquids—including strong acids, strong alkalis, and organic solvents. It is widely used in industries such as chemicals, pharmaceuticals, electronics, electroplating, and environmental protection, making it particularly suitable for applications requiring the transfer of high-purity, highly corrosive media.

II. Key Features and Functions

**Constructed from perfluorinated materials; exceptional corrosion resistance**

Key components—including the pump body, diaphragm, and ball valves—are manufactured from perfluorinated materials like PTFE.

Capable of withstanding highly corrosive media such as 98% concentrated sulfuric acid, concentrated hydrochloric acid, hydrofluoric acid, and aqua regia.

Wide operating temperature range (-20°C to 150°C), suitable for transferring high-temperature, corrosive media.

Completely eliminates metal ion contamination, ensuring media purity.

**Pneumatic drive; intrinsically safe and explosion-proof**

Powered by compressed air; requires no electricity, completely eliminating the risk of electrical sparks.

Complies with ATEX explosion-proof standards; suitable for flammable and explosive hazardous environments.

Safe operation in challenging conditions, including flammable, explosive, and dusty environments.

**Leak-free design; excellent self-priming performance**

Utilizes pneumatic diaphragm technology to completely isolate the medium from moving parts.

Ensures a 100% leak-free transfer process, preventing environmental pollution.

Self-priming lift of 5–7 meters; starts without the need for priming (filling the pump).

Allows for dry running without damaging the equipment.

**Adaptable to complex media; easy maintenance** Easy maintenance

Capable of transporting corrosive media containing solid particles (up to 10mm)

Handles special liquids with high viscosity (up to 8000 cP) and crystallization tendencies

Modular design allows for wear-part replacement in just 5–10 minutes

Seal-less design (no mechanical seals) significantly reduces maintenance costs

Adjustable flow rate for operational flexibility

Stepless flow adjustment via air supply pressure control (0.2–0.8 MPa)

Maximum flow rate of 32 m³/h and maximum head of 70 meters

Simple start/stop control via the air supply
