• Pumping high viscosity fluids such as polymers, pastes and doughs at high pressure into a mixer, die or other downstream equipment
• Pumping heterogeneous mixtures of difficult, viscous materials
• Heating or cooling viscous material streams for downstream processing
• De-gassification of viscous fluids for downstream processing

• Simple, effective pumping of high viscosity pastes and dough at viscosities up to and including rubber
• Pressures up to 500 bar can be generated using specially-designed screws and barrels
• Integrated safety features, including pressure-relief flange at the output
• De-gassification of pastes in the compression zone of the extruder (resulting in gas ejection at the inlet)
• Jacketed barrel and hollow screw allow excellent thermal control of the material being pumped.
• Hygienic and flameproof options for a wide range of applications

The range of EPS machines covers the following ranges of performance:

• Typical maximum flowrates from 10 to 5000 kg per hour
• Downstream system pressures to 200 bar (depending on fluid type).  Higher pressures are possible, on request.
• Rotational speeds typically 250 rpm maximum
• Typical motor power from 0.25kW to 15kW
• Stainless steel or through-hardened steel wetted parts
• ATEX and UL hazardous area options
• Hygienic design options to 3A and EHEDG guidelines

Providing simple and flexible pulsation-free pumping of viscous materials, EPS machines use single screw extrusion to generate high pressures.  Traditionally used in the rubber and plastics industry to pressurise and melt materials, the screw design includes feeding, compression and metering sections to cater for the different operational zones of the machine.  EPS machines typically also feature specially-designed barrels which allow high pressures to be developed, as well as pressure-relief flanges to ensure safe operation.

High quality gearmotors and bearings are fitted as standard to give long service life and minimal downtime.  Hygienic and flameproof options are available.
