The brandnew animation of the KNOLL progressing cavity pump MX

The progressing cavity pump MX form KNOLL Maschinenbau characterized by it’s modular design and it’s serviceability is the perfect solution for your application.

 

Impressive appearance for the KNOLL progressing cavity pump – The MX as a suction pump

 

Apart from numerous applications in which hygienic aspects of the KNOLL progressing cavity pump MX play a central role, the MX can also used in an extremely beneficial manner in KNOLL’s core business. One new application is the use of the MX in KNOLL‘s in-house Test Centre. Here, KNOLL tests the operability of all cooling lubricants and conveying systems.

For the wet test, the tank on the installation to be tested is initially filled with cooling lubricant from a central collection tank. All pumps, valves and other installation components are set to meet customer-specific requirements. This means that the wet testing procedure takes place largely under real conditions. If the installation test is successful, the cooling lubricant is drawn off again by a vacuum suction unit into a vacuum tank. Thanks to its excellent suction performance, the MX is able to draw off the cooling lubricant continuously from the vacuum tank even at a negative pressure of -0.7 bar and to convey it into the sludge tank of the central collection tank.

Small dirt particles, e.g. welding debris, which may have entered the installation during the production process, are no problem at all to the MX. From the sludge tank, the cooling lubricant is then routed to the attached KNOLL filter for thorough processing. When the cooling lubricant has been filtered, the circuit closes and the purified cooling lubricant is available once again in the central collection tank for a further wet test.

Without the use of the MX, the vacuum suction unit would require a considerably higher tank capacity. The vacuum would also have to reduced regularly to ensure that emptying with a conventional pump is possible.

The KNOLL “sugar worm” – the MX progressing cavity pump in action in the confectionary industry

sweetsConfectionary – who can resist the sweet temptation? On average, Germans eat 32 kg of sweets in a variety of forms every year. Hard candies are particularly popular, coming as they do in many different flavours.

The MX by KNOLL Maschinenbau is ideal for producing this well-loved confectionary. Hanover-based Hänsel Processing GmbH, a respected plant and systems supplier in the confectionary industry, has been happily using the MX progressing cavity pump for a number of years now.

Crucial factors for the customer are the hygienic design of the MX and its excellent cleanability. As with many plant constructors, the MX scores highly for its compact overall length which allows the pump to be integrated into the overall system in a space-saving way. The high dosing accuracy of the MX enables Hänsel Processing to fill exactly portioned batches of hard candy mass.

For this application, KNOLL uses a heated stainless steel double jacket for the MX as standard. This allows media such as toffee, fondant or jelly mass to be kept at a constant temperature and, thus, to be conveyed easily and gently. The uniform elastomer wall thickness of the EvenWall® stator provides good, even heat transfer between the double jacket and the medium. The uniform thermal expansion of the stator elastomer has a very positive effect on its useful life and, thus, on the productivity of the overall system.

Do you also work in the confectionary industry, and have we managed to arouse your interest in our “sugar worm”?
If so, please give us a call. It’s a safe bet that you’ll find a suitable KNOLL MX solution for your application in our product range.

Why does KNOLL use a bearing block for the MX?

The MX progressing cavity pump by KNOLL offers product-conserving delivery, ease of servicing and virtually pocket-free design, as well as a string of other advantages.

KNOLL uses a bearing block in each of its progressing cavity pumps from the compact MX10 version to the XXL-sized MX100 version. This unique feature clearly sets KNOLL apart from its competitors.
By using a bearing block, we can supply the pump without a drive unit. The advantage here is that the customer receives a ready-to-use standby pump with no need for laborious shaft sealing unit assembly.

Bearing Chair MX20Another advantage is that the axial forces are absorbed by the bearing block and do not have to be factored into the design of the geared motor. This allows the use of smaller and more cost-efficient drive units.
A stainless steel-bearing block is standard on the MX10 and MX20 models, which means that KNOLL is able to supply these pumps entirely made from stainless steel. Used in combination with a stainless steel geared motor, the MX is the perfect solution for hygiene environments and similar applications because it can be cleaned easily and quickly.
