Submersible sewage pumps ISP

Submersible sewage pumps ISP could be used for pumping of domestic and industrial waste waters, drainage and underground waters. This kind of equipment could be implemented in complete sewage and rain water pumping stations, water and waste water treatment facilities, industrial and agricultural systems. The pumps are manufactured of long-wearing materials, such as cast iron and stainless steel, which could ensure their safe operation.
Nominal diameter of ISP pump pressure inlet amounts to 65 mm. Products from pump series 3 with electromotors of 15 KWT and lower, are with direct start. Pumps from ISP model range series 4, equipped with more powerful electromotors (more than 15 KWT) are started according to scheme “star-delta”.

Double mechanical sealing of shaft (installed in the standard version of the pump) protects electric motor from leakage. Pump spiral casing has been specially developed in order to reduce the volume of deposits on mechanical sealings.
Special method of mechanical sealing installation coupled with bearings leads to shortening of shaft's length hence to increase of its hardness, vibration decrease and reduction of possible leakage number. In consequence of all the above mentioned features pump life time has become longer.
ISP pumps are equipped with motors of IP68 protection grade, that allows their implementation under water ensuring high efficiency of cooling. Winding insulation class F provides an opportunity to work at high temperatures.
This type of pumps could be delivered with additional cooling cover, so it would be possible to use it in case of low liquid level and dry mounting.
