Product Overview

The SMC PAP3310-P13-BN is a pneumatically driven diaphragm process pump engineered for precision transfer of high-purity and chemically aggressive fluids in industrial process systems. Manufactured by SMC Corporation, a global leader in pneumatic control technology, this pump utilizes a double-diaphragm working principle in which compressed air is alternately applied to two flexible diaphragms connected by a common shaft. The reciprocating diaphragm action creates a positive-displacement pumping effect that is gentle on shear-sensitive media, self-priming, and capable of running dry without damage. With a PTFE or similar high-compatibility wetted path and a robust non-metallic body construction, the PAP3310-P13-BN is purpose-built for chemical dosing, slurry transfer, and contamination-sensitive process loops where metallic contact and seal leakage must be eliminated.

Technical Specifications

Engineering Features & Advantages

• Precision Performance: Double-diaphragm positive-displacement action delivers smooth, pulsation-dampened flow with excellent self-priming capability and dry-run tolerance, protecting shear-sensitive and abrasive process fluids.
• Industrial Reliability: Built for continuous operation under severe industrial conditions, with a sealed non-metallic wetted path that resists corrosive attack and eliminates shaft-seal leakage paths common in rotary pumps.
• Direct Fit Replacement: Exact dimensional and functional compatibility with original OEM standards, allowing drop-in replacement without modification to existing pneumatic supply or process piping.

Typical Industrial Applications

Ideally suited for chemical dosing and transfer in water and wastewater treatment plants, high-purity fluid handling in semiconductor and electronics manufacturing, aggressive chemical circulation in electroplating and surface finishing lines, and slurry or reagent transfer in pharmaceutical and food-grade process systems.
