F E AT U R E SThe Liquiflo Centry® Series Centrifugal Pumps were exclusively designed for chemical, agricultural, general industrial, or specific OEM applications. Both economically-priced and ruggedly constructed, these pumps are madefrom heavy-walled investment cast 316 SS. Compared to other manufacturer’sproducts, the extra corrosion allowance offered by our Centry Series pumps willadd years of service life even when pumping harsh and corrosive chemicals.

In general purpose applications, they promise unequaled performance andyears of trouble-free operation. The back pullout design allows for quick andeasy maintenance since the volute can be kept in-line while the internal components of the pump are replaced or repaired. The Centry Series pumpsare available with either Mechanical Seal or Magnetic-Drive.

R u g g e d C o n s t r u c t i o nCentry® Series pumps are extremely durable and well-suited for aggressive chemical applications. Their oversized shafts reduce L3/D4 ratio minimizingunwanted shaft vibrations which extend the life of the seal and bearings.

SEALED PUMP

MOTOR

Mechanically Sealed Pumps:

• Close-Coupled or Long-coupled mounting available.

• Type 21 Seals are standard withoptional Type 9 Seals available.

• Standard seal materials are Carbon Seal Face with Ceramic Seal Seat. Other options available.

• Closed Impeller improves pump performance, simplifies axial positioning of impeller and eliminates axial loads transmitted to motor bearings for extended service life.

• Back Pullout Design simplifies maintenance.

• Impeller Positioning Ring eliminates guesswork when trying to position impeller on close-coupled sealed pumps. With this unique design, a new or replacement sealed pump is fitted to the motor without having to adjust theimpeller position. The Centry Series is the only pump available with this feature.
