The Jung Process Systems twin-screw pump is a positive displacement pump with two screws that rotate within a stainless steel casing without touching each other or the walls. The manufacturer is Jung Process Systems GmbH, Auweg 8, Kummerfeld, approximately 25 km north-west of Hamburg. Steiner Ukraine is the official representative of the manufacturer in Ukraine and is listed in its partner catalogue.<\/p>\n
The company pursues two tracks of expertise: stainless steel processing since 1972 as part of the Jung Group and in cooperation with Jung & Co., and pump manufacturing since 2009. Jung Process Systems is a second-generation family business. The quality system is certified to ISO 9001.<\/p>\n
A screw pump moves the medium through sealed chambers formed between the screw flights and the casing. The chambers move continuously from the inlet to the outlet, so the flow is uninterrupted.<\/p>\n
A single-screw pump (progressive cavity pump) has a single rotor rotating within an elastomeric stator. The rotor and stator are in contact, and this friction pair wears down, especially with abrasives. Dry running destroys the stator in minutes.<\/p>\n
A twin-screw pump has two parallel screws synchronised by a gear train. They rotate in opposite directions and do not touch<\/strong> Neither one another, nor the casing. There are no friction pairs in the flow path.<\/p>\n Hence four practical implications.<\/p>\n The feed is uniform.<\/strong> Unlike a lobe or diaphragm pump, the flow is not interrupted on each cycle. For dosing, filling and long pipelines, this eliminates the need for dampers.<\/p>\n The product does not break down.<\/strong> Progress cavity pumps neither shear nor cut the medium. The structure of pastes, emulsions, suspensions with inclusions, and viscous masses is preserved.<\/p>\n There is no contact wear and no valves.<\/strong> The abrasive does not wear away the friction pair because there isn't one. There are no valves in the design either.<\/p>\n One pump operates for both product and cleaning.<\/strong> With a change in speed, the pump switches from pumping a viscous product to pumping a cleaning solution at a flow rate sufficient for CIP. A separate cleaning pump is not required.<\/p>\n The manufacturer divides the range into two series.<\/p>\n Typical applications of CHEMSPIN according to the manufacturer: adhesives, anti-corrosive underbody protection, tank farms and tank terminals, paints and varnishes, detergents.<\/p>\n Capacity by size using CHEMSPIN as an example: 50 \u2014 up to 20 m\u00b3\/h, 70 \u2014 up to 40, 90 \u2014 up to 100, 105 \u2014 up to 180, 125 \u2014 up to 300 m\u00b3\/h.<\/p>\n A viscosity range spanning six orders of magnitude \u2014 from 0.5 mPa\u00b7s (thinner than water) to 1,000,000 mPa\u00b7s (a thick paste) \u2014 means that a single model size handles both the product and the cleaning solution in the same process.<\/p>\n The pump is fully cleaned in the system by CIP without disassembly. Sterilisation in the system is performed with steam or hot water.<\/p>\n The design has no dead zones where product remains between cycles. This is a basic EHEDG requirement and the reason why the pump is permitted for direct contact with the food product without manual cleaning.<\/p>\n Practical consequence for the line: a single unit feeds the product in the process mode and pumps the cleaning solution in the CIP mode. A separate cleaning pump, separate piping and a separate maintenance point are not required.<\/p>\n Product contact materials:<\/strong> stainless steel 1.4404, 1.4539 or 1.4462 (optional).<\/p>\n Elastomers:<\/strong> HNBR, FPM, EPDM, FFPM \u2014 with FDA approval.<\/p>\n Shaft seal:<\/strong> single or double-acting mechanical seals, or lip seals, dry-running safe. The choice depends on the medium and operating mode.<\/p>\n Certification:<\/strong> The manufacturer's quality system is ISO 9001. For hygienic applications, the manufacturer cites EHEDG, 3-A Sanitary Standards, FDA approval for elastomers, and EC 1935\/2004 compliance. For hazardous areas, CHEMSPIN ATEX for zones 1, 2, 21, and 22.<\/p>\n The specific list of documents for your property is confirmed upon ordering.<\/p>\n The manufacturer names five areas: the food industry, beverages, pharmaceuticals, cosmetics, and the chemical industry.<\/p>\n The logic for choosing the series is simple.

Frequently Asked Questions<\/h2>\n
\nIn a twin-screw pump, the screws touch neither each other nor the casing, so there is no friction pair that wears down from abrasives, and dry running does not destroy the stator\u2014there is no stator in it.<\/p>\n
\nUp to 300 m\u00b3\/h \u2014 size 125.<\/p>\n
\n20\u201335 bar depending on the model size. The HYGHSPIN DOUBLE FLOW version delivers up to 50 bar.<\/p>\n
\nFrom 0.5 to 1,000,000 mPa\u00b7s. Higher values by agreement with the manufacturer.<\/p>\n
\nNo. That same pump recirculates the cleaning solution at an increased speed. SIP is carried out with steam or hot water.<\/p>\n
\nThe manufacturer cites EHEDG, 3-A Sanitary Standards, FDA compliance for elastomers and EC 1935\/2004. The list of documents for a specific application is confirmed upon ordering.<\/p>\n
\nYes, the CHEMSPIN ATEX is designed for zones 1, 2, 21 and 22.<\/p>\n
\nThe screws do not touch each other or the casing, so there is almost no displacement. The pump is used for pastes, emulsions, and products containing inclusions.<\/p>\n
