High Head Submersible Drainage pump
WQH high head submersible drainage pump is suitable for pumping and dredging of sewage and sludge in various harsh environments, the electric pump is under-pump type, capable of pumping the surface water on the working surface; it can be submerged in water for a long time or exposed to the surface, covering a small area, easy to install and use, reliable and durable, with long life. This series of products have large flow, high head, weight by, and easy to move.
- Chemical, petroleum, pharmaceutical, mining, paper industry, cement plant, steel plant, power plant, coal processing industry, etc.
- Urban sewage treatment plant drainage system, municipal engineering, etc.
- Construction sites and other industries convey granular sewage and dirt, also can be used to pump clear water and with corrosive media.
- Mine drainage, water lifting (mining, corrosive liquids), seawater, chemical enterprises, ponds, fish ponds, etc.
- Medium temperature does not exceed 40℃, medium density＜1050kg/m3, PH value in the range of 4-10.
- The main parts of the pump are made of cast iron or ductile iron, so it cannot be used for pumping strongly corrosive or corrosive solid particles, but it can be adapted to corrosive fluids by special design at the request of users.
The overall structure of the built-in type is vertical and downwardtype with built-in motor structure.The outlet is generally above thepump.There is an interlayer between shell of motor and pumpshell.When the water pump drains,the medium flows through theinterlayer and out of the water outlet at the top to cool themotor;Even without water,the interlayer still has water cooling themotor to ensure the motor will not be overheated and burnt.
