DCM
Micro centrifugal pump manufactured by DAYUAN which is based on special designs, scientific structures, low cost, high efficiency, good seal function, stand wear and tear, safe and reliable, and used widely.
Application
Micro centrifugal pump is suitable for industrial and urban water supply, high-rise building pressurization, fire protection system, garden irrigation, long-distance water transportation, farm irrigation transportation.
Pump
Cast iron pump body
Stainless steel/Brass impeller
AISI 304 shaft
Max. liquid temperature: +40℃
Moter
Motor with copper winding
Built-in thermal protector for single phase motor
Insulation class: B
Protection class: IP44
Max. ambient temperature: +40℃
Work Principle
Micro centrifugal pump lifting water by rotating the impeller to make the water centrifugally move. Before the pump is started, the pump casing and the suction pipe must be filled with water. After starting the motor, the pump shaft drives the impeller and the water to rotate at a high speed, which makes water into the pressurized water line of the pump. Centrifugal water pump has become the most widely used water pump in agriculture because of its simple structure, convenient use and maintenance, and high efficiency.
