BL Marine Vertical Direct-coupled Centrifugal Fire Pump

Overview

BL (L), CZ Series marine horizontal (vertical) direct-coupled centrifugal pump, for the transport of water and physical and chemical properties similar to liquid water. This type of pump is BA type pump based on the improvement of the structure, has the advantages of small, light weight, simple structure and convenient handling characteristics. The performance parameters of BA pump with the same. Liquid temperature not exceeding 100, with mechanical seal. I produced BL type marine centrifugal pump impeller with silicon brass, a pump shaft is made of stainless steel, suitable for ships pumping bilge water, main and auxiliary cooling water, fire and other.
