Overview:
Type DG pump is single-suction, multistage, segmental centrifugal pump. It is used for feeding water if low-middle pressure boiler as well as pumping high lift water of factory and city.It is provided for delivering similar to clear water. The temperature of the liquid for type 200DG43 pump is -20ºC~150ºC. The maximum inlet pressure is not allowed more than 0.59MPa

1) The inlets and the outlets of all type DG pumps are vertical upward.
2) The axial force gets balanced with the help of balance disk. The shaft seal usually uses packing seal or mechanical seal. Type DG85-67 and DG155-67 pumps use sliding bearings which get lubricated with dilute-oil. The others use rolling bearings.
The direction of rotation
The rotation of the pump rotor is clockwise looking from the motor to the pump.
The material of main parts of the pump
The medium-contacting parts are made of cast iron except that of type 200DG43 pumps are cast steel.
Complete provision range
Pump, motor, check valve, sluice valve and common bed-plate or pump bed-plate.
Please give indication of the material of main parts of pump in contract. If you have any special requirement, please contact us without hesitation.

Type description
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 80ºC.
Type DF: designed for pumping corrosive liquids with suction pressure up to 0.6 MPa and temperature up to 105ºC. 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 150ºC 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
Flow: 3.75~185m /h Corollary power: 4.0~400kW
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
rotor shall be balanced by balancing discs. Return water piping shall be designed be-
tween the balancing chamber and suction casing.
Pump shall be flexibly coupled with driving motor, clockwise rotation looking from
motor side.
