D DF DY DG Horizontal Multistage Centrifugal Pump

D DF DY DG Series pumps are in multistage single casing sectional horizontal construc-tion designed in accordance with API610 , for high-head pumping various kinds of liquids without solids, applicable to a wide range of tough and heavy circumstances.

Type D: ideal for low & medium pressure applications of clean water or similar liquids in miming and municipal water supply and drainage. Liquid Temperature up to 80℃.

Type DF: designed for pumping corrosive liquids with suction pressure up to 0.6 MPa and temperature up to 105℃. Materials of construction, type of seals and the internal construction may vary according to specific liquid to be pumped.

Type DY: Ideal for oils and petrochemical products with temperature up to 150℃ and

viscosity up to 120 centipoises.

Type DG: is a horizontal multi-stage centrifugal pump and suitable for transporting pure water (with the contained foreign matters' content less than 1% and graininess less than 0.1mm) and other liquids of both physical and chemical natures

similar to those of pure water.

DG model middle 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.

Performance range of model DG series

Head: 69~684m Inlet diameter: 40~150mm

DG model hypo-high-pressure Boiler Feed Water Pump is applicable to transport medium with temperature of not higher

than 160 , and is also applicable for small boiler water supply or transporting medium similar to hot water.

Performance range of model DG series

Flow: 15~300m /h Corollary power: 75~1250kW

Head: 390~1050m Inlet diameter: 65~200mm

Features:

Standard piping design in accordance with API610 and flange drilled to meet GB, DIN

and ANSI Standards plans.

● Sectional single casing construction, the suction casing, stage casing and discharge

casing shall be tied together with tie-bolts and sealed with metal-to-metal surface

sealing.

● Soft packing as standard shaft sealing, external water cooling system designed for

cooling of gland cover and stuffing box. Mechanical seal also available upon request.

● The rotor shall be supported at both ends by slide or ball bearings that will be lubri-

cated with either oil or grease and cooled by circulation water. The axial thrust of the
