Frequently Asked Questions About Exhaust Gas Cleaning Pumps
What is an exhaust gas cleaning pump?
An exhaust gas cleaning pump is used in marine exhaust gas cleaning systems (EGCS) to circulate seawater or process water through the cleaning process. Reliable pump operation is essential for maintaining system performance, vessel uptime, and compliance with emission regulations.
Are exhaust gas cleaning pumps the same as scrubber pumps?
In most marine applications, yes. Scrubber pump is a commonly used term for pumps operating in exhaust gas cleaning systems (EGCS). Depending on the application, these pumps may be used for seawater circulation, process water recirculation, chemical treatment, or other supporting functions within the system.
What are the key requirements for an exhaust gas cleaning pump?
Exhaust gas cleaning pumps must handle corrosive media, operate continuously, deliver high flow rates, and maintain reliable performance over many years of service. Energy efficiency is also important, as these pumps often run around the clock.
Why is corrosion resistance important in exhaust gas cleaning systems?
Exhaust gas cleaning applications expose pumps to seawater and other aggressive fluids that can accelerate wear and corrosion. Corrosion-resistant materials help extend service life, reduce maintenance requirements, and improve operational reliability.
Which materials are commonly used for exhaust gas cleaning pumps?
For demanding marine applications, stainless steel and Super Duplex stainless steel are commonly used due to their excellent corrosion resistance and durability. These materials help ensure reliable operation in aggressive operating environments.
Can exhaust gas cleaning pumps be used in open-loop, closed-loop, and hybrid systems?
Yes. Exhaust gas cleaning pumps are used in open-loop, closed-loop, and hybrid EGCS configurations. The optimal pump selection depends on system design, flow requirements, fluid characteristics, and operating conditions.
Why is pump efficiency important in exhaust gas cleaning applications?
Because exhaust gas cleaning pumps typically operate continuously, higher hydraulic efficiency can significantly reduce energy consumption and operating costs throughout the lifetime of the vessel. In many cases, pump efficiency has a major impact on total lifecycle costs.
How can I select the right exhaust gas cleaning pump?
The correct pump depends on factors such as flow rate, head, liquid characteristics, temperature, and system configuration. Using a pump selection tool can help identify the most efficient solution for a specific exhaust gas cleaning application.
