CLH Series Marine Vertical Centrifugal Pump
Product Features
The pump structure is divided into two connection forms: direct-coupled and intermediate coupling-connected. The direct-coupled structure offers compact size and light weight, while the intermediate coupling-connected form allows for easy disassembly and maintenance. When repairing the latter, you only need to remove the intermediate coupling first, and then the bearing housing, pump body, and impeller can be removed as a whole. There is no need to disassemble the motor, motor base, or inlet/outlet pipelines, making maintenance highly convenient.
