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.
