Description

Self-Priming Monoblock Water Pump with Open Impeller

Applications

This self-priming monoblock water pump features an open impeller design, making it ideal for handling clean or slightly dirty water. Equipped with an internal check valve at the suction outlet, the pump prevents siphoning when stopped and ensures automatic re-priming during every start.

Even if the pump is only partially filled and the suction hose is completely empty, it will self-prime reliably—making it perfect for use in flood irrigation systems, water drainage, and general-purpose water transfer.
