BL series marine horizontal direct-coupled centrifugal pump

The BL series marine horizontal direct-coupled centrifugal pump is designed for the transport of water and liquids with physical and chemical properties similar to water. This pump is an improved version of the BA type, offering a compact, lightweight design with a simple structure and easy handling. It is suitable for ship's bilge water pumping, main and auxiliary cooling water, fire fighting, and other uses. The pump's performance parameters are the same as those of the BA type, and it can handle liquid temperatures up to 100°C with a mechanical seal. The impeller of the BL series marine centrifugal pump is made of silicon brass, and the pump shaft is made of stainless steel
