PUMPS & FILTRATION
Leak-free Mag-Drive Pumps ideal for hazardous applications
Reliable , leak-free pumping is essential in many fluids handling applications and absolutely critical when the process involves corrosive , toxic , explosive or any other type of hazardous liquids . Magnetically coupled centrifugal pumps , are by design , one of the safest and most reliable options and the DICKOW KM Series of pumps is an excellent example of a safe , reliable and competitively priced pump for these types of applications .
Available from pumping specialists MICHAEL SMITH ENGINEERS , the KM Series is a range of sealless , single-stage , volute casing pumps with a maximum flow rate of 70m ³/ hr maximum differential heads to 65 metres and maximum operating temperature up to 200 º C . A key benefit of the magnetic coupling design is that it results in a sealless pump and because mechanical seal failure is sometimes regarded as the ‘ Achilles heel ’ of other types of pump , these potential problems are eliminated . This minimises the potential for downtime and lost production along with no cross contamination of the pumped liquid , less wastage , no environmental hazards due to leaks and increased operator safety .
These robust , reliable pumps can handle liquids with viscosities between 0.1 cP and
200 cP and are available in either horizontal or vertical configuration and in a choice of wetted materials of either cast iron , cast steel and stainless steel . The vertical configuration option with the motor mounted on the top eliminates the need for a base plate so is ideal when space is limited .
The single elements of the multipolar magnet coupling are manufactured from Cobalt- Samarium with unlimited lifetime durability while the magnets in the driven rotor are completely encapsulated and not in contact with the liquid . Power is transmitted to the hermetically sealed liquid end by a bank of external magnets and the inner and outer magnet rings are locked together by magnet forces and work as a synchronous coupling .
The internal clearance between the rotor and containment shell is 1.0mm for the standard containment shells which allows handling of fluids containing small solids . The pump drive shaft is carried by oil lubricated anti-friction bearings rated for 25,000 operating hours and the oil bath is protected by a labyrinth seal .
When fitted with suitable Ex-drive motors , the pumps can be applied in hazardous area Group II , category 2 situations while they also meet the basic health & safety requirements of Explosionproof Directive 94 / 9 EC and so are suitable for sites with increased safety requirements .
Typical applications for Dickow KM Series pumps include tanker unloading and unloading and transferring to and from bulk storage vessels . For example , in food or beverage processing , soap and cosmetics manufacturing , biofuels production , bulk chemical storage , or wherever there is a need for reliable , leak-free pumping of larger volumes of hazardous liquids .
