cast iron pneumatic diaphragm pump for oil and gas industry

The cast iron pneumatic diaphragm pump is a volumetric pump driven by compressed air, utilizing diaphragm reciprocation to transfer liquids. It efficiently handles corrosive, particle-laden, high-viscosity, volatile, flammable, and highly toxic fluids, making it ideal for demanding industrial environments.

Main Features

• Convenient maintenance: Simplified design with easily disassembled stainless steel bolts, adjustable internal volume, and reduced downtime for cleaning and repairs.
• Precision fit parts: Precision-machined end bearings ensure correct valve stem positioning and wear resistance; easy valve stem replacement supports long-term efficient operation.
• Protected discharge port design: Common end discharge port prevents vapor leakage, protecting air motor seals and facilitating reservoir operations.
• Sturdy external structure: Corrosion-resistant casing prevents leakage; aluminum center parts are epoxy coated, with optional 316 stainless steel for demanding conditions.
• Fluid compatibility: Multiple housing material options (aluminum, stainless steel, ductile iron, polypropylene, PTFE, etc.) ensure compatibility with various fluids.
• Durable seal design: Tightly locked diaphragm provides positive liquid sealing, preventing leaks and ensuring lasting performance.
• Heavy-duty diaphragm plate: Robust clamping secures the diaphragm, minimizing downtime from failure or leakage.
• Long-lasting valve stem: Made from 300 series stainless steel for superior corrosion resistance and reliability.
• Corrosion-resistant elastomeric materials: Valve seat and ball use various elastomers for optimal sealing, fluid compatibility, and extended pump life.

Summary

Cast iron pneumatic diaphragm pumps combine high efficiency, corrosion resistance, and easy maintenance. With a range of materials and configurations, they deliver reliable long-term performance even in harsh operating conditions. Ideal for chemical, food, pharmaceutical, and environmental applications, these pumps excel at conveying corrosive, volatile, or high-particle fluids.

Applications

• Chemical industry: Transfer of corrosive, volatile, and highly toxic liquids.
• Food & beverage: Handling high-viscosity materials such as sauces and syrups.
• Environmental protection: Sewage treatment and particle-laden liquid transport.
• Oil & gas: Suitable for oil and fuel transfer.
