High-Efficiency CWX Series Self-Priming Centrifugal Vortex Pumps

The CWX series is a compact, two-stage marine self-priming vortex pump combining centrifugal and vortex impellers for efficient fluid transfer. It is specifically designed for pumping freshwater and seawater in vessels, catering to drinking, washing, and sanitary systems (T ≤ 85°C).
Its self-priming capability eliminates the need for pre-filling, while robust materials like cast iron and bronze ensure durability in harsh marine environments.
The pump operates at 2900 rpm (50Hz) with flow rates ranging from 0.83 to 10 m³/h and heads up to 40 m, making it ideal for diverse onboard applications.

Equipped with mechanical seals and optimized hydraulic design, the CWX series delivers stable performance with minimal maintenance. It features a steep head curve, reducing sensitivity to system pressure fluctuations, and supports suction of liquids with weak corrosivity or small impurities.
Certified by global authorities like CCS, ABS, and DNV, it meets stringent marine standards for safety and efficiency. Models like 1.5CWX-4A offer enhanced power (4 kW) and efficiency (38.1%), ensuring reliable operation in demanding conditions.

CWX Series Marine Self-Priming Vortex Pump: Reliable Fluid Transfer for Marine Applications

The CWX Series Marine Self-Priming Vortex Pump is engineered for efficient fluid transfer in marine environments, ideal for pumping freshwater, seawater, and mildly corrosive liquids. Designed for applications such as drinking water supply, sanitation, and onboard cleaning, this pump delivers robust performance with a flow rate of up to 16.3 m³/h and a head of 4 meters, ensuring reliable operation under demanding conditions . Its compact design (weighing as low as 1.5 kg) and 45% efficiency make it a versatile choice for space-constrained vessels .

Durable Construction for Harsh Marine Environments:
Crafted with marine-grade materials such as corrosion-resistant cast iron and bronze, the CWX pump withstands prolonged exposure to saltwater and abrasive media. The vortex impeller design minimizes clogging risks, allowing smooth handling of liquids with minimal particulate content
. This durability ensures longevity even in high-salinity or humid conditions, reducing maintenance costs and downtime.

Self-Priming Capability for Instant Operation:
Equipped with advanced self-priming technology, the CWX pump achieves immediate water discharge without manual priming or bottom valves. With a suction lift of up to 4 meters and a rapid priming cycle, it is perfect for emergency systems or intermittent use . The 2900 r/min motor speed ensures quick startup, while the optimized NPSHr (Net Positive Suction Head required) of 2.2 meters enhances operational stability.

Customizable Solutions and Certifications:
The CWX Series offers customizable configurations to meet diverse marine needs, including multiple power options (e.g., 1.5 kW to 4 kW) and compliance with CCS (China Classification Society) standards for maritime safety . Whether for commercial ships, offshore platforms, or leisure vessels, these pumps can be tailored to specific flow, head, and material requirements, ensuring seamless integration into existing systems.
