Centrifugal pumps according to ISO 5199 and ISO 2858 >

CombiChem represents a range of horizontal centrifugal pumps, designed to ISO 2858 (EN > 22858 > (DIN 24256) ), suitable for handling low viscosity, clean or slightly contaminated liquids. The construction of CombiChem complies entirely to ISO 5199. The CombiChem offers a great variety of possible shaft sealings, bearing constructions and also a wide range of different materials, such as stainless steel, bronze, nodular cast iron or cast iron. The leakfree version of the CombiChem is the CombiMag , a magnetic coupled centrifugal pump, especially developed for the chemical industry. >...

The CombiChem is, as the name says, perfectly suited for operation in chemical industries. The pump has been designed entirely according to ISO 5199. The ISO 5199 standard defines important technical details of centrifugal pumps according to ISO 2858, used in chemical industries. The 100% leakproof version of CombiChem, the magdriven CombiMag, is the ultimate solution when it comes to transporting harmful or environmentally dangerous liquids. > CombiChems availability in several materials, the ample choice of shaft sealing options and the rigid bearing construction makes it a very reliable...

CombiChem has a great variety of possible shaft sealing options: mechanical seals as well as stuffing box packing. All configurations are equipped with shaft sleeve, so the pump shaft never comes into contact with the pumped liquid. CombiMags mag-drive can be considered as a 100% leakproof shaft sealing option of the CombiChem. The following shaft sealing configurations are available: Mechanical seal options: 1. single mechanical seal unbalanced, MG12 & M7N 2. single mechanical seal balanced, HJ92N > 3. single mechanical seal, dry- running protection or pressure-less quench, unbalanced,...

CombiMag is provided with a Hastelloy C or stainless steel separation can, which separates the pumped liquid entirely from the environment. The pump is 100% leakproof. The power from the driven pump shaft is transmitted to the impeller shaft by means of strong SamariumCobalt magnets. The pump shaft is provided with an outer rotor. This rotor is internally covered with magnets. The impeller shaft is connected to an inner rotor that is externally covered with magnets. When the driven shaft rotates the opposite magnet poles on inner and outer rotor attract each other. This causes the inner...
