CB Series Ship Horizontal Centrifugal Pumps | Enhanced Reliability for Marine Applications
Product Overview
The CB Series Ship Horizontal Centrifugal Pumps represent a significant advancement in marine pumping technology, developed as an improved successor to the legacy BA Series. Engineered with premium copper alloy and stainless steel components, these robust centrifugal pumps offer superior corrosion resistance and extended service life in demanding marine environments. Featuring dual sealing options—mechanical seals or packing seals—the CB series maintains identical performance parameters with the original BA type pumps while delivering enhanced reliability and meeting stricter marine-grade component requirements.
This upgraded series includes specialized variants:
-
CBH Series: Equipped with relay devices achieving exceptional suction capabilities up to 15 meters
-
CBX Series: Features sliding vane vacuum pump conversion for self-priming operation
Designed for transferring water and fluids with similar physical/chemical properties, the CB series handles liquid temperatures up to 85°C, making it ideal for vessel bilge pumping, fire protection systems, sanitary water handling, and freshwater/seawater applications across marine, industrial, and agricultural sectors.
