Traditionally used as a cement binder for hot-slab paving, liquid bitumen must be handled at very high temperatures in order to keep it at a workable viscosity. However, even at high temperatures liquid bitumen can be an extremely viscous and shear-sensitive product. Therefore, shipyard operators and tanker owners demand a pumping technology that has been specifically designed to transfer highly viscous liquids over great distances. Realizing the importance for pumping equipment that feature the design and performance characteristics required for transferring highly viscous liquids, Blackmer offers its S Series Twin Screw models for these marine applications.

Hapag Lloyd will equip ships of the 13,200-TEU Hamburg Express class and other vessels with the CM-1000® pump control system. The CM-1000 system controls the flow rates of seawater cooling pumps based on the temperature of the fresh water and the current need for coolant. As a result, the amount of seawater pumped into the seawater cooler matches requirements, saving electrical power on board the ship.
The pump monitoring system CM-1000 Series is now available with a new active valve control functionality. This option delivers energy savings of potentially up to 85 percent. It also reduces maintenance by up to 50 percent and provides safer operation, short term return-on-investment and long term savings for total ownership.
The KSB Group has supplied 70 pumps and around 700 butterfly valves to the new cruise ship Europa 2 run by Hamburg-based cruise ship organiser, Hapag-Lloyd Cruises. The pumps’ spectrum of applications is varied and ranges from cooling the drives in the submerged pods to transporting seawater in ballast systems, supplying fire-fighting systems and handling fresh water, service water, waste water and sewage.
