Stan-Cor PST ANSI Centrifugal Pumps

Solid PVDF (Kynar) & PTFE Construction — to 700 GPM

The Stan-Cor PST is the ANSI centrifugal pump that sets the industry standard for corrosive and abrasive process-fluid applications. These solid non-metallic pumps provide exclusive design advantages over high-alloy, fiberglass and lined metallic designs, delivering the most cost-effective solution for dirty, difficult fluids.

Stan-Cor PST pumps conform to ANSI B73.1 specifications for dimensions, shaft deflection and bearing life. If you have been looking for a reliable alternative to costly high-alloy pumps, the wicking problems associated with fiberglass pumps, or the complications of lined pumps, the Stan-Cor PST is the answer.

Technical Specifications

Solid Component Construction Advantages

• No liners separating or collapsing
• No permeation
• Impellers that can be trimmed to the application

In addition to solid liquid-end components, Stan-Cor PST pumps incorporate design features that extend mechanical-seal life:

• Concentric casing — reduces hydraulic imbalances inside the ANSI pump casing
• Duplex angular contact bearings — eliminate axial motion of the impeller and shaft

Typical Applications

Stan-Cor PST pumps are used extensively for the transfer of aggressive acids and process chemicals, including:

Additional common duties include lime-slurry wet FGD gas scrubbing and other abrasive slurry services where alloy or lined pumps fail prematurely.
