Ways to ensure self-priming and to increase suction Grundfos pump
Grundfos pumps and installations needed in many sectors of the economy.
Greater need for self-priming pumps have the construction industry, maritime and river fleets. Most of the construction and installation operations of the foundations, and underground waterworks, laying and repair of engineering structures and networks requires lowering the groundwater level. In this case, the end result, the quality and intensity of major works depends largely on the perfection and reliability of dewatering facilities.
In most cases the water level in the soil is provided as a result of the continued maintenance of an extensive network of special dewatering wells (well point), submerged in the ground, a relatively high vacuum (7-8 meters of water. Art.). Installation to ensure the maintenance of the vacuum, work in difficult conditions, as with a pumped water from the drained soil inevitably sucked into the air in quantities sometimes exceeding the volume of water flow.
The efficiency of dewatering plants depends largely on the effectiveness of air removal. Such a situation arises in the courts. A distinctive feature of the pumps for routine draining and pumping ballast holds of the side and double bottom tanks, ships, is the need to install self-priming device, as the level of pumped liquid, usually located below the axis of the pump.
Terms of the bilge pump is very complex. Eksluatatsionnaya suction in most cases exceeds 7 m, and the presence of detachable joints and fittings in the suction line results in an air suction to the pump must pump the water-air mixture with a gas content up to 25%. Installation of Grundfos pumps in PEX Plumbing system and sewer Taco 006 significantly reduces cost and simplifies the work on the construction of underground (buried) of the Grundfos pump.
