• Screw pumps for low sulfur fuels KRAL IMO 2020

IMO-Regulations 2020

How to Comply With the new IMO-Regulations.

What is changing under the new global sulfur cap?

To significantly reduce the amount of sulfur oxide emanating from ships, the International Maritime Organization (IMO) has set a global limit for sulfur in fuel oil on board ships of 0.5 % by 2020.

What does this mean for ships equipped with fuel pumps?

Ships will have to use fuel oil on board with a sulfur content of no more than 0.5 %, against the current limit of 3.5 % . Sulfur is important for the lubrication quality of fuels. Pumps will have to meet the challenge of handling fuels with low sulfur content, which means low viscosity and therefore  decreased lubrication. Viscosity goes down to 1.1 cSt and fuel loses lubrications, which causes damage to the pump. 

KRAL pumps are specially treated and able to handle low sulfur fuel oils. As a partner for global players, KRAL plays an important role in supplying pumps for vessel conversions from Heavy Fuel Oil (HFO) to Low Sulfur Fuel Oil (LSFO). Whether for the exchange of pumps only or complete conversions, KRAL can assist you.

Choices of how to comply with the new sulfur specifications.

Ship owners need to decide if they want to continue to use Heavy Fuel Oil in conjunction with scrubbers or exhaust gas cleaning systems or switch to Low Sulfur Fuel Oil.

0.1 % and 0.5 % sulfur content.
  • Fuel loses lubrication properties
  • Different quality of fuel per blend and supplier


KRAL solution
Special surface treatment of screws and housing.

MDO (DMA, DMX), DMA (DMB).
  • Proven fuel and widely available
  • Viscosity goes down to 1.1 cSt with poorer lubricity.

KRAL solution
Every KRAL pump can handle these fuels.

HFO 3.5 % scrubber retrofit.
  • Cheaper fuel and quick return on of investments
  • Needs to handle high viscosity fuels without any leakage.

KRAL solution
Hermetically sealed magnetic coupling pumps.

To optimize costs and delivery times for our customers, KRAL has expended its portfolio with a serial production range for frequently used low 
sulfur pumps. Thanks to targeted standardization in the manufacturing of these pumps, the reliability and high quality for which KRAL is known can be offered while maintaining shorter delivery times and price advantages.
