Close-Coupled

Discflo close-coupled disc pumps in in-line and self-priming versions for industrial processing, batch and reactor feed, environmental work and fluid transfer of viscous, abrasive, corrosive and multiphase fluids. The impeller-free Discpac with generous internal clearances and no radial load on seals and bearings gives smooth, pulsation-free laminar flow and handles up to 90% solids and up to 80% entrained air or gas without cavitation.

Key technical parameters

• Head: over 300 m (1,000 ft TDH, range maximum)
• Pressure: up to 172 bar (2,500 psi, range maximum)
• Viscosity: up to 700,000 cP
• Solids passage: up to 250 mm (10 in.); solids content up to 80%
• Drive: Electric (close-coupled to the motor)
