Pump in pipe (water-cooled pipeline pump), also known as silent pump or land pump, as a new type of integrated water supply equipment, integrates the Submersible Electric Pump into the pipeline, gives full play to the advantages of the submersible electric pump is not afraid of flooding during diving operation, and the medium (water) forced cooling motor, excellent cooling effect, no need for a fan, etc., effectively solves the problems of large volume and high noise of traditional water pumps. The product model is divided into 5 series from 200, 250, 300, 400, 500GZB, with flow rate from 10-1000 tons/hour, head design from 20-300 meters, and power from 4-500kW. It can be widely used in farmland irrigation, domestic water, pumping and drainage, building secondary water supply, domestic water for high-rise residences, hotels and other civil buildings, municipal pipe network pressurization, pneumatic pools, water tank water supply equipment and traditional pump room renovation and other fields. It has the advantages of small footprint, low noise, pollution-free water quality, and self-priming irrigation pump. Moreover, it is easy to install, and can be used in parallel and series with multiple units, and can also be installed vertically or obliquely. The follow-up technical team will also develop a variety of pump series such as tank in pipe pump, siphon tank (drainage tank) type on the basis of pump in pipe, and welcome the majority of outlets and demand units to come to negotiate.
