EC series single-stage vertical inline centrifugal pumps EC series single-stage vertical inline centrifugal pumpsutilize the centrifugal force generated by rotating impellers to drive fluid movement and achieve liquid transfer. The pump primarily consists of a main shaft, impeller, pump casing, and mechanical seal assembly, which are connected to the motor via a coupling. The EC series operates effectively under high-temperature and high-pressure conditions, making it suitable for applications such as boilers, cooling towers, air conditioning systems, and as a booster pump in water supply systems. Its inline pipeline design allows for direct installation in horizontal piping systems with identical inlet and outlet diameters on the same level, ensuring a more compact structure and streamlined piping arrangement.
Pump Connection Method
Top-pull design: The motor and pump body are structurally separated. Pump head serves as the connecting component between the motor and pump body, with an O-ring used as the sealing element between the pump head and pump body.
Flange dimensions comply with the PN16 specifications outlined in GB/T 17241.6, ISO 7005-2, or DIN 2501 standards.
