Shuttle Block Pumps

Shuttle block pumps employ a unique pumping principle - a combination of rotary and piston pump. The shuttle block pump is a self-priming rotary pump. There are only three pumping ele- ments--rotor, piston and shuttle. The rotor is keyed to a single shaft and runs concentric in the pump casing. Like a true piston pump, this pump can handle highly viscous liquids or thin vola- tile material with unmatched suction characteristics and yet smoothly without pulsation. This pumping principle--unlike cen- trifugal or gear pumps--gently handles the product without break- ing it down, emulsifying, foaming, chewing or heating. Such a simple construction has resulted in extremely rugged and main- tenance-free pumps with very low noise levels. Most of the diffi- cult pumping problems can be overcome by a shuttle block pump. Some of the common applications handled by shuttle block pumps are: unloading of tankers, rail wagons, transfer of edible oil, fuel oil, soap liquor, sodium silicate, bitumen, etc.
