Product Description

DG Boiler Feeding Horizontal High Head Multistage Water Pump

D/DG pump is a horizontal multistage centrifugal pump, which is fit for transportation clean (impurity content is less than 1%, granularity is less than 0.1mm) and or other liquid with physical and chemical characters like clean water.

D pump transportation medium temperature is not more than 80°C, which is fit for mine discharge and water feeding to factory and city.

DG pump transportation medium temperature should not be more than 105°C, which is fit for water feeding to small boiler or similar applications.

DG Centrifugal water pump operating conditions

• Medium temperature: <+105ºC
• Capacity range: 3.75-500 m3/hr
• Head range:  49-680 m

• Speed: 1480-2950 r/min

Notice: Y series motor can't be used in well. YB series motor can be used in well, but can't be used for excavation industry. If used for excavation industry, must use YBK series motor.
