CPT ANSI Process Pump

The LM/CPT is engineered for the customers to meet their exacting requirements, whether for an upstream produced water or refinery caustic application. The CPT has several seal chambers available for a wide range of ASME flush plans and mechanical seals.

A-890 grade 3A Alloy  LM/CPT ANSI pumps are frequently used in services where resistance to both corrosion and abrasion is necessary. That is why the standard stainless steel chosen
for wet-end pump components is ASTM A-890 Grade 3A.
This duplex cast steel (ferritic austenitic) with high molybdenum and nitrogen content:
• Offers corrosion resistance superior to conventional cast 316SS (CF-8M) and equal to or better
than 317SS (CG-8M).
• Provides excellent abrasion resistance (230 BHN) that, when used in mildly abrasive services,
may last 30% to 40% longer than 316SS.
• Features clearly superior mechanical properties over austenitic alloys and is comparable
to most duplex alloys including CD4-MCu and SS2205.
