Jung Process Systems HYGHSPIN Twin Screw Pumps

Jung Process Systems has been specialising in the design and manufacture of the 'HYGHSPIN' hygienic twin screw pump since 2009.


  • Tank filling and emptying is also possible for mobile tanks (HGV, tanker lorries, tanker ships)
  • Emptying of containers
  • Transfer within tank plants
  • Transfer within production processes (supply, pressure boosting, discharge)
  • Metering and filling

The advantages of HYGHSPIN twin screw pumps reap benefits in all industries:

  • The innovative design does not require a pump bypass for the cleaning of the plant or system. This saves space and costs and enables the conveyance of the CIP fluids alongside the product transportation with just one pump.
  • Our twin screw pumps are compact and have a space-saving design so that integration in new installations, or also the replacement of an existing pump, generally requires less space and reduces difficulties.
  • The block design prevents damage from unaligned couplings, is easy to clean and protects the coupling effectively against corrosion influences
  • HYGHSPIN twin screw pumps are equipped with an inspection opening and guide pins so that maintenance is considerably simplified.

The fluid is transported axially (conveyed through the pump rather than rotated. Every rotation positions the product with the incline of the feed screw and not back to the circumference of the rotors. Lower conveying speeds result in a very gentle conveyance for sensitive products. Chambers are filled on the suction side at all times and then emptied on the pressure side. The conveying behaviour is therefore almost pulsation free and ensures a perfect suction capability and a lower NPSH value with the reduced turbulences.

The self-balancing rotors with lower moments of inertia result in an extended revolution range of up to 4000 rpm. One pump is sufficient for a very broad flow volume range and viscosity range. The pumps can be implemented for various media and simultaneously as a CIP-Conveying pump. The same pump can be utilised for various tasks.

Twin Screw pumps do not require a bypass for cleaning. The pumps will be cleaned by the complete CIP-Flow. The shaft seals will be rinsed at the same time and are positioned directly in the main flow. This results in much higher flow rate speeds and a considerably improved cleanability. The construction is free of cavities and self-emptying. EHEDG and 3A Certificates are also available. A sterilisation by utilising steam (SIP) is also possible without any special measures.

The flexibility of the HYGHSPIN pumps means that a pump bypass and an external CIP-Conveying pump can be dispensed with. The valve and their control system can be omitted. The investment, maintenance and service costs, as well as the failure of components, sink considerably.

The conveyor elements operate contact free. Abrasion cannot therefore enter into the product. The pump is safe-to-run dry with the relevant shaft seal. Very abrasive media can also be conveyed in conjunction with strengthened conveying elements. This results in higher availability for the pumps and longer service life.

Twin Screw pumps are made of stainless steel and are therefore corrosion free. Grey cast iron components will not be utilised in the design. This also ensures that the external hygiene standards will be maintained. HYGHSPIN pumps are also particularly easy to service. Guide bolts simplify the assembly of the housing components. The inspection opening enables the flank clearance for the feed screws to be set directly in the system without dismantling the motor and the gearbox housing.

Twin Screw pumps in block construction reduce the space requirement in the system. Pumps and motor shaft are jointly centred by utilising positive form locking so that any resulting damage can be excluded from non-aligned or tensioned couplings. This therefore increases the operational safety. The shaft coupling is protected against corrosion and the pumps can be easily cleaned from the outside. Dirt and contamination build up below the protection against coming into contact or also the need for a larger base plate are prevented.
