Built for the Harsh Realities of Scrubber Systems

Scrubber systems operate under highly demanding conditions, where pumps must handle corrosive seawater, chemical additives, and continuous operation without failure. Selecting the right pump is critical to maintaining system performance and avoiding costly downtime.

The Challenge

Corrosive media
Seawater combined with chemicals creates aggressive operating conditions that accelerate wear and corrosion.

Continuous-duty operation
Scrubber systems typically run continuously, placing high demands on pump reliability and durability.

Operational risk
Unplanned downtime can impact compliance, increase costs, and disrupt vessel operations.

Integration constraints
Limited space and system complexity require flexible and well-adapted pump solutions.

DESMI Solution

Corrosion-resistant design
Stainless steel materials and proven design principles ensure long service life in aggressive environments.

High reliability in operation
Engineered for continuous-duty performance with minimal maintenance requirements.

Proven marine performance
Extensive experience in scrubber applications across vessel types and system configurations.

Where DESMI Pumps Fit in Scrubber Systems


Scrubber Circulation Pumps

 

The primary function in most scrubber systems is circulating seawater through the scrubber tower.

 

Requirements:

  • High flow capacity
  • Continuous-duty operation
  • Resistance to corrosive media

 

 

Auxiliary Functions

 

Supporting applications include sludge handling and system drainage.


Requirements:

  • Robust construction
  • Ability to handle contaminated media
 


Process and Recirculation Pumps

 

In closed-loop or hybrid systems, pumps are used to circulate process water and manage chemical treatment.

 

Requirements:

  • Stable flow control
  • Chemical compatibility
  • Reliable continuous operation

Scrubber Pump Selection App by DESMI

 

A marine scrubber pump will typically run for the next +20 years. Why not use five minutes to find the most efficient?

 

We have developed an app which makes it easy to find the optimal pump for your scrubber project in a few simple steps:

 

  • Run the app from your web-browser
