Engineered Polymer Composite Construction offers cost-effective corrosion-resistance and is lightweight, non-galling, non-sparking, and non-conductive.

Unitized Case with Integrally Molded Flanges at the suction and discharge nozzles are fully gusseted to ensure structural soundness under extremes of applied nozzle loads.

Externally Adjustable, Semi-Open Impeller is inherently balanced and provides consistently high efficiencies while minimizing maintenance.

Shaft/Bearing System operates well below the first critical speed, resulting in less shaft whip and longer bearing life.

Bearings can be lubricated by external flush, or self-lubricated by the pump fluid.

Single-Piece Column is lightweight, filament-wound, reinforced fiberglass composite but generously sized and thick in cross-section for strength and rigidity.

PolyChem S-Series Fluoropolymer Lined Overhung ASME Chemical Process Pump

Description: The Flowserve PolyChem S-Series ASME pumps are non-metallic, conventionally sealed pumps designed to meet ASME B73.1 dimensional standards. The S-Series is designed with PFA-lined wet ends for superior corrosion resistance and temperature allowance.

CPXV ISO and API Chemical Sump Pump

Description: Compliant with ISO 5199, the CPXV is a vertical sump pump incorporating state-of-the-art hydraulic design for efficient and reliable service. It is highly customizable to meet a wide range of needs. And, for oil and gas installations, the CPXV is available with many ISO 13709/API 610 compliant features.

FRBHJC Overhung Cantilever Sump Pump

Description: The FRBHJC is a true stiff-shaft vertical cantilever design developed to handle the thick, pulpy mixtures found in the pulp and paper industry, as well as numerous other industries, particularly when flushing liquids are not available or cannot be tolerated.

PolyChem GRP Engineered Polymer Composite Overhung Chemical Process Pump

Description: The PolyChem GRP pump is a single stage, end suction, centrifugal pump designed to ANSI/ASME B73.5 M Standards. With corrosion resistance superior to more expensive and highly-alloyed metals and costs closer to that of ductile iron, the PolyChem GRP pump has proven to be the low-cost, long-term solution in acidic and chloride-rich applications.
