-
Reliable – the Blackmer Abaque Series pump is
self-priming to 29.5 ft (9 meters) manometric lift. This pump
is able to run dry continuously without detrimental effects.
The pump is capable of running in forward or reverse.
-
Seal Free – eliminates leaks and
contamination. Fluids are contained within the hose. The hose
is the primary maintenance component.
-
Principle of Operation – Pumping action is
achieved by compression of a circular loop of elastomeric hose
with two diametrically opposed rotating shoes. This rotational
motion forces the fluid in the hose to move ahead of each
shoe. When each shoe reaches the end of the loop, the
reinforced tube immediately returns to its original shape,
thereby ensuring suction and priming. The pump housing is
partially filled with lubricant, aiding smooth running of the
shoes on the hose. The inside of the hose and hose inserts are
the only pieces of equipment in contact with pumped fluids,
allowing aggressive and contaminated fluids to be pumped.
