1. The pump utilizes a 300BYXZXW1000-12-55 type vacuum-assisted self-priming centrifugal pump produced by Jiangsu Boyu Pump Industry; the inlet is 300mm and the outlet is 250mm.

2. The pump is equipped with a dry-run protection system to safeguard the impeller from damage due to high-speed rotation within the pump chamber when there is no liquid; this protects both the mechanical seal and the impeller.
