The structural type is multi-stage split-casing pump ADK series;
The impellers are back to back symmetrically arranged, which offsets the axial force of rotor so that the service time of the bearing can be extended.
Shaft seals at two ends are mechanical seal.
Pump and electrical motor are connected with a flexible diaphragm coupling with an intermediate segment. Under the condition that the intermediate segment of the coupling is dismantled, bearing and mechanical seal can be examined or maintained without moving the electrical motor.
