QD, QDG series multistage centrifugal sea water pumps and QDL series vertical multistage centrifugal pumps are multiple single stage impeller combined together makes head high. They are used for sea water and liquids with concentration less than 1%, particles smaller than 0.1mm, or liquids similar to water in physical and chemical property. QD series pump’s medium temperature can not exceed 80℃, QDG series can not exceed 150℃. Head: 76-1080m, flow rate: 3-600m3/h. We can use different materials of HT200, QT500, ZG500 stainless steel etc by different medium. This series horizontal multistage centrifugal sea water pump, both ends are supported, the casing portion is in a sectional form. it is connected to and actuated by a motor via a resilient clutch and the rotating direction of it. viewing from the actuating end. is clockwise. 

Multistage Sea Water pump and low pressure boiler water supply pump is applicable to transport medium with temperature of not higher than 105℃, and is also applicable for small boiler water supply or transporting medium similar to hot water.
