ZLDB pumps are a modern product to substitute for traditional ZLB axial flow pumps sets and QZ submersible axial flow pump. ZDLB pump are vertical single base long shaft axial flow pumps, with the liquid flowing in axial direction.They have large capacity, low head, high efficiency and good anti-cavitation performance. The pump is used to transfer clean water or other liquids with similar physical and chemical properties with water.The highest temperature of the transferred liquid can be 50 degree Celsius.It can be widely used in agriculture irrigation, civil supply and drainage, water circulation in industry power station, dock water level control and other water conservancy projects. Due to both pump and motor connected as an integral set, so the advantages of ZLDB pump over other type of pump as follow: ·The pump and motor are mounted on a base, the pump body can be lifted out and in from the base hole; ·Saving the project price; ·The alignment of the pump shaft and line shaft can be guaranteed as the pump is a whole, so the alignment work is cancelled; ·The installing and disassembly of the pump can be finished on the motor floor, it is not necessary to go into the water poor for the installing workers; ·The suction pool water not be pumped out while maintainance; ·The length of the pump part under the base and the type of out flow depend upon low water level at the suction side and base level can be determented by customer. The ZLDB pumps are available for diameter of 350~1600mm.
