HYGHSPIN Hopper twin-screw pump – the efficient solution for non-flowable products

Hygienic, gentle, economic

The HYGHSPIN Hopper is an addition to the worldwide proven stainless steel HYGHSPIN series. The innovative twin-screw pump with hopper opening is able to handle products with a viscosity of up to 1000 mPa·s without problems. Its screws are extended, so that non-flowable products are drawn in below the hopper opening (like an extruder) and fed to the pump chamber. This ensures particularly gentle product transport – external extruders can be eliminated completely.

Consequently, the HYGHSPIN Hopper represents a very attractive 3-in-1 solution: Infeed, conveying, and cleaning are carried out in a single unit. It is available in modular form or with free shaft end,

and comes in sizes of 70, 90, 105 and 125. Max. pumping volume is about 20 m³/h. In the standard version, the pressure difference is max. 10 bar. Optionally, up to 25 bar are possible.

Advantages at a glance
  • Self-feeding version
    By means of lengthened screws with extruder function and an enlarged inlet
  • Particularly gentle with sensitive solids
    The product falls into the feed chambers by gravity
  • Particularly suited for boiling media
    Minimised infeed losses ensure maximum protection against cavitation

    Moreover, all the other advantages of HYGHSPIN twin-screw pumps apply
  • Considerable cost savings
    Reduced investment and maintenance costs
  • Best quality
    Made completely of stainless steel
  • Exceptional service-friendliness
    The pump must not be removed from the plant for maintenance work
  • Utmost flexibility
    A wide range of products, viscosities, and quantities can be handled with a single pump
  • Pumping is gentle and smooth
    Low speed, minimum pulsation, no pressure surges
  • Highest hygiene level
    No dead spaces, and particularly good flushing of the shaft seal
  • CIP and SIP:       
    Cleaning and sterilisation within the plant, use as CIP feed pump
