Performance & Advantage
Type DG pump is single-suction, multi-stage, segmental centrifugal pump. It is used for feeding water of low-middle pressure boiler as well as pumping high lift water of factory and city. It is provided for delivering clear water or other liquid which is physically and chemically similar to clear water. The temperature of the liquid for type DG85_80 and 200DG43 pump is -20ºC ~ 150ºC, the temperature for the liquid for the others usually is -20ºC ~ 105ºC. The maximum inlet pressure is not allowed more than 0.59Mpa ( 6kgf/cm2 ).
Description of pump type:

Example 2 40DG140 × 3.
40 _ inlet diameter of pump ( mm ).
DG _ Single-suction, multi-stage, boiler feed water pump.
140_ Single-stage head of pump ( m ).
3 _ pump stage number.
Construction:
The inlets and the outlets of all type DG pumps are vertical upward. The axial force gets balanced with the help of balance disk. The shaft seal usually uses packing seal or mechanical seal. Type Dg85_80, 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 Dg85_80 and type 200DG43 pumps are cast steel. Complete provision range
Pump, motor, check valve, sluice valve and common bedplate or pump bedplate. Please give indication of the material of main parts of pump in contract. If you have any special requirement, please contact us without hesitation.
