Description

This series is a single-suction, multi-stage, segmented centrifugal pump. The maximum temperature of the conveyed liquid is 130°C.

The flow range is 3.5--130mm³/h, and the head range is 60--1100m. It is mainly used for boiler feed water in medium and small thermal power plants,

and can also be used in water supply occasions requiring small flow and high lift. It has the characteristics of good structural steel, stable operation and long life.
Manufacturing materials of main parts: flow parts such as water inlet section, interruption section, water outlet section, guide vane, etc.-ordinary cast iron,

ball milled cast iron or stainless steel; impeller-ball milled cast iron or stainless steel; friction of balance device-surfacing resistance Grinding material; shaft-carbon

steel or stainless steel.

The meaning of the numbers in the pump number: such as DC50--80.50--design point flow rate (m³ /h), 80= single-stage head (mm)
