Blackmer
Peristaltic Hose Pumps
 The
Abaque pump operates on the peristaltic principle which was
patented in 1925 by Mr. Horthaus of France. It is classified as
positive displacement pump meaning that a fixed and known amount
of fluid is discharged per revolution of the pump with flow
independent of discharge head. The pump operates by compressing
a specially designed elastomeric hose between a set of two or
more shoes attached to a rotor and the internal wall of the pump
case or housing. Fluid in the hose is forced from the inlet side
of the pump toward the discharge by the squeezing or compressing
motion of the shoes on the rotor of the pump as it rotates. This
peristaltic action is in some ways similar in nature to that of
the human digestive tract.
Applications:
From viscous and/or abrasive sludges to water thin,
non-lubricating fluids, corrosive chemicals or sheer sensitive
materials, Blackmer's Abaque series peristaltic pump is the
technology of choice. Due to the unique operating principle of
this pump, typical applications span from wastewater to chemical
processing to food manufacturing.
Features and
Benefits:
- Available in
10 different sizes that provide flow rates of .07 to 290 gpm
(15 to 66,000 L/h).
- Will handle
abrasive fluids with little wear since only the hose and hose
inserts are in contact with the material being pumped.
- Since only the
inside of the hose and hose inserts are in contact with the
pumpage, aggressive and contaminated fluids can be processed
without the devastating damage experienced by other pumping
technologies.
- Hoses are
constructed of natural rubber, Buna, or EPDM within the pump's
casing, provide high levels of volumetric accuracy for
sampling, transfer, and metering applications.
- Ability to
pass solids in the material being pumped.
- Dry-run
capability allows tank and line stripping.
- Seal-less
design eliminates leaks, contamination and wear problems
associated with difficult to seal products.
- Self-priming
up to 29.5 feet (9 meters).
- Reversible
operation allows pumping in both directions.
- Durable
construction of ductile iron and steel construction allow
higher discharge pressures up to 217 psi (15 bar).
- Low
maintenance requirements of the hose and shoes.
