Helicoidal screw pumps

SDM has its own line of helicoidal screw pumps (SDflow series).




SDflow® - S

Thanks to its design, the helical pump allows for pumping without pulsations of fluids with high solid and/or gas contents and with viscosities of up to 1,000,000 cps.


SDflow® - F

The compact, linear design allows for pumping without pulsations, the product remaining unaltered. It is applicable for the transfer of different types of slightly abrasive, viscous fluids with a proportion of solids of less than 5%.


SDflow® - T

With feeding hopper.

Wide range of pumps designed for pumping the following products:

  • Products with high viscosity
  • Products with high concentrations of dry matter
  • Products with solid blocks that tend to form tunnels in the feed screw
  • Products requiring a pre-supply system to encourage their intake


SDflow® - H

The H+ hygiene line is made entirely of AISI 316 stainless steel and is designed to meet the most demanding hygiene standards, eliminating any possible blind spots where organic material could accumulate and cause subsequent product contamination. This version can be quickly cleaned and CIP connections can be included on request.

  • Complies with regulations in force in the food and/or chemical-pharmaceutical sectors

SDflow® - B

  • Dosing pumps for flow rates of up to 2400 l/h.

The SDflow®-B pump line allows for small flow rates of dense, viscous fluids containing solid suspended particles to be pumped accurately, maintaining a continuous flow with low pulsations and no vibrations at all times.
