It sounds like you’re referring to a Special End Suction Pump (Engineered) — likely a type of custom or application-specific centrifugal pump used in various industries such as oil & gas, water treatment, power generation, or chemical processing.

What Is a Special End Suction Pump
An End Suction Pump is a type of centrifugal pump where the suction is on one end (axial) and the discharge is from the top (radial). The “engineered” part indicates that the pump is custom-designed or tailored to specific operational requirements, often involving:
-
Special materials (e.g. duplex steel, Hastelloy, titanium)
-
High pressure or temperature handling
-
Corrosive or abrasive fluids
-
Compliance with industry standards (API 610, ANSI, ISO)
-
Specific performance characteristics (flow, head, NPSHr)
