Propeller and mixer come together efficiently

A novel propeller/mixer combination has been developed to virtually eliminate energy waste.

Mixing Solutions will be showing its combination Lancer propeller mounted on the Cutlass side-entry mixer on Stand 24 at StocExpo Europe (Rotterdam, The Netherlands, 28th to 30th March 2006).

The propeller/mixer combination has been developed to virtually eliminate energy waste, especially welcomed by refineries with increased demands for refined products but facing rising costs.

A problem for refiners when pressured to operate at levels approaching maximum capacity is to ensure that fuel quality specifications are always fully met, which means that stored product must be thoroughly blended.

Many mixing processes waste large amounts of electrical energy, which is said to account for roughly half of a refinery's operating costs.

The higher efficiency and effectiveness of the Lancer propeller eliminates this energy drain by developing a "focused flow" that channels power into a jet-stream, maximising efficiency.

compared with "pitch adjusted propellers" and other mixing systems from other companies, the Lancer generates increased penetration, produces higher upward velocity movement which ensures that the tank contents are "rolled" bottom-to-top-to-bottom for the most accurate blending.

Users tests with the Lancer/Cutlass combination, report a full 2:1 mixing advantage, with mixing time cut in half for the same energy input.

Additionally, the design of the Lancer/Cutlass system also incorporates a mechanical shutoff device that is engineered to adhere to the strictest environmental regulations.

The shut-off device is designed into the shaft and mounting flange with a stainless steel taper-to-taper shutoff feature that securely "locks" the system so that no leakage occurs during bearing and seal change-out procedures.
