Big fow vertical axial flow pump
Description
ZLB series pumps are single stage vertical axial flow pump, with the liquid flowing in axial direction. The pump is used to transfer clean water or other liquids with similar physical and chemical properies with water. The highest temperature of the transferred liquid can be 50 ℃. The ZLB pump has large capacity and low head which is widely used in agriculture irrigation, civil supply and drainage, water circulation in industry power station, dock water level control and other water conser-vancy projects.
Construction
