Peristaltic Pump DULCOFLEX DFDa

Pump capacity up to 35,000 l/h. Back pressure up to 15 bar.

The peristaltic pump DFDa is designed for maximum pump capacities and high pressures and is winning customers over with its noiselessness and long service life. It is fitted with shoes and fabric-reinforced hoses – perfect for industrial use.

Product description

Maximum pump capacities and high pressures

The pump housing is filled with glycerine to reduce friction. A ball-bearing mounted rotor ensures extremely smooth running and a long service life. In tough industrial use, the DFDa conveys volumes of up to 35,000 l/h at back pressures of up to 15 bar.

As an option, with pumps of the DFDa product range, a vacuum device can be used to help the hose to return to its original shape, thereby improving their suction behaviour and ensuring the even feed of highly viscose media.

Your benefits

  • Ideal for pumping pasty, high-viscosity, abrasive and gaseous media
  • Self-priming
  • Guaranteed not to run dry
  • Reversible pumping direction
  • Hose materials suitable for various chemicals
  • Handling to protect the hose at high pressures
