Grundfos Pumps cast iron type on paragraphs and something with which they deal.
In addition, the impeller if necessary sputtered thin tungsten carbide to resist wear. Tests conducted by Grundfos (USA), showed that the UP 15-42 F type pumps have provided 98-100% dirt resistance. With abduction mud cooling pumps in a standard way – fluid – is unacceptable. And then pumps have the advantage of Grundfos UP 15-42F – the device inside an independent cooling system with an aqueous solution monopropilenglikolya as an agent-cooler. Special propeller embedded in the cartridge block of mechanical seals, causes cooling solution in motion, eliminating the risk of clogging the cooling system.
On the grounds of consumers throughout Europe and the U.S. the combination of the Grundfos UP 15-42F series pump with frequency converter has an impressive effect of reducing the downtime that occurs due to clogging of pumps and the cost of subsequent maintenance. Countless examples of this can help to overcome prejudices of customers on the use Taco 006 for pumping mud.
Recently added to range of Grundfos pumps progressive cavity (PC), which are circulating screw pumps. Impeller in these devices replace the rotor in the form of a large corkscrew placed in the cowling with a spiral. When rotating inside the stator, it forms a set of cavities that move uniformly from the point of suction to the pressure points, moving sediments and slurries with high viscosity, abrasive, density, and also contain rags or gas phase. Now, with the submission of Grundfos pumps PC and with the growing success of the Grundfos UP 15-42F pumps, Grundfos recommends an efficient and cost-effective equipment for feeding sludge and sediment moisture content up to 55%.
