DC-Horizontal End Suction Pump DC and DS series single-stage horizontal centrifugal pumps utilize the centrifugal force generated by the rotating impeller to drive fluid movement and complete liquid transfer. They primarily consist of a pump body (comprising a main shaft, impeller, pump casing, and mechanical seal) connected to a motor via a coupling.
The DC and DS series are mainly used in HVAC systems, cooling towers, air conditioning systems, and can also serve as booster pumps in water supply systems.
The DC and DS series feature cast construction and a retractable design, allowing the impeller, coupling, and motor to be extracted without disconnecting the pump from the pipeline system. The mechanical seal adopts an innovative quick-disassembly structure—replacement only requires removing the coupling and seal housing, enabling mechanical seal maintenance without dismantling the pump body or motor.
