Close Coupled Centrifugal Pumps with Screwed Motor

In essence, the pump and motor are tightly coupled together without a separate coupling, and the motor generates power using a screw-based mechanism. This type of centrifugal pump is known as a "Close Coupled Centrifugal Pump with Screw Motor" because the motor is directly mounted onto the pump body, sharing a single shaft. The motor design is specifically a "screw motor" that rotates the pump impeller using a screw-like mechanism, making the pumping system compact and economical.
