Inline Circulation Pump

EC series single-stage vertical pipeline centrifugal pump through the centrifugal force generated by the impeller of the rotating pump to drive the rotation of the fluid to complete the liquid transport, mainly by the main shaft, impeller, pump shell, mechanical seal combination of the pump body and the motor through the coupling. EC series can work under high temperatures and pressure, mainly used in boilers, cooling towers, and air conditioning systems, and can be used as a booster pump in water supply systems. its tubular structure ensures that the pump is installed directly in a horizontal piping system with the same inlet and outlet level and the same pipe diameter. This design makes the pump structure and piping more compact.
