DY/DYP/DYJ multistage centrifugal pump is designed and manufactured by API610 Standard (version 8) after we fully understood the introduced advanced technologies. The pumps are mainly used to convey petroleum, chemicals, chemistry and boiler water, with conveyance medium temperature range T=-45~+200℃.
 
  a. DY/DYJ pumps can be divided into different types, namely, horizontal type, single-cased type, radial split type and multistage sectional centrifugal type. The pump horizontal center line support, suction port and exhaust port flanges are all vertically upright. The pump main pressure-bearing parts are forged parts.
DYP pumps can be divided into different types, namely, horizontal type, single-cased type, radial split type and multistage sectional centrifugal type. The pump has bottom support feet, its suction port is horizontal and exhaust port flanges can be either vertical upright or horizontal. The pump main pressure-bearing parts are forged parts.
 
  b. Pump impellers are structured of orientation level by level, while impellers, balance drum and shaft sleeves are installed on pump shaft on orders. Also, rotator parts have bearings on both ends for radial support and axial orientation.
 
  c. The pump axial-thrust balancing structure has double-balancing drums, while left axial forces are released by thrust bearings.
 
  d. The pump suction part, middle part and exhaust part are connected by through bars.
 
  e. The pump bearing is sliding type, the thrust bearing is either thrust-ball bearing or Mitchell thrust bearing, and bearing lubricating method is self-lubricating or forced lubricating.
 
  f. The gasket-type seal is done by metal surface, winding-gasket seal and O-ring seal. Shaft seal is a  mechanical seal. Washing method is in accordance with AP1610 Standard.
