Pneumatic Piston Pump For High Viscous Fluids

Compact, air‑driven piston pump engineered for transferring high‑viscosity, corrosive and particle‑laden fluids in industrial production and process applications. Designed for reliable, low‑maintenance operation, this pneumatic piston pump delivers stable flow at pressures up to 0.7 MPa (7 bar / 100 psi) and handles dry suction lifts to 6 m.

Key applications

• Paints, coatings and polyurethane systems
• Adhesives and sealants
• Automotive and industrial coating operations
• Chemical, oil and lubricant transfer
• Food and pharmaceutical production lines (where compatible wetted materials are specified)

Primary benefits

• Robust performance with viscous and shear‑sensitive fluids, and liquids containing solids or entrained air
• Corrosion‑resistant construction and polished stainless surfaces to preserve material integrity and maintain flow efficiency
• Low spares count and simple service procedures to reduce operating and maintenance costs
• Long mechanical service life suited to continuous or intermittent duty

Technical specifications

• Maximum working (air) pressure: 100 psi (0.7 MPa / 7 bar)
• Maximum flow rate: 18 GPM (68 L/min)
• Maximum dry suction lift: 6 m
• Fluid inlet: 1-1/2" NPT(F) or BSP(F)
• Fluid outlet: 1" NPT(F) or BSP(F)
• Air inlet: 1/2" NPT(F) or BSP(F)
• Maximum air consumption: 34 SCFM (≈0.817 m3/min)
• Connection types available: NPT or flange (GB)
• Air-to-fluid pressure ratio: approx. 4:1

Materials and options

• Polished stainless steel wetted surfaces as standard for improved transfer speed and chemical compatibility
• Multiple material configurations available to match corrosive media or hygienic requirements (specify material when ordering)

Installation & maintenance notes

• Simple installation: compatible with standard NPT/BSP piping or flange connections
• Designed for easy routine maintenance; minimal wear parts reduce downtime and service costs
• Select wetted-material options and seals appropriate to your fluid to ensure compatibility and regulatory compliance

Recommended use

Ideal for production lines and maintenance operations that require reliable transfer of thick coatings, adhesives, oils or chemical slurries where pneumatic drive, dry‑suction capability and resistance to abrasive/corrosive fluids are required.
