ENGINEERING NOTES

Published data and the information still needed

ANSI Pumps Pro offers the D Mark III Unitized Self-Priming as a non-OEM replacement for the Durco Mark 3 unitized self-priming dimensional pattern, using D Mark III power ends. An approved model-specific curve, priming limits and outline-dimension sheet are not published here. Those records must be confirmed for the selected configuration before fit and performance are quoted.

Frequently asked questions

What information is needed for suction-lift review?

Provide static lift, suction-line size and layout, liquid and temperature, startup / restart requirements, and required flow and head. Nameplate and installation photos are useful.

Are pump dimensions and priming limits available?

The reviewed source does not publish an approved curve, priming limit set or dimension sheet for this unitized model. Request reviewed configuration-specific data before confirming selection or installation fit.

Can the existing base and connections be reused?

That depends on the installed dimensions, nozzle orientation, baseplate and proposed configuration. Include drawings or clear photos so these interfaces can be checked.
