What information on a pump's mechanical drive is commonly listed on the nameplate?

• A. The color of the housing.
• B. Type (motor or engine) and rpm.
• C. The year of manufacture.
• D. The serial data.

Answer: (B)

When you read the nameplate for a pump’s mechanical drive, you’re looking for the drive’s identity and speed: the type of drive (whether it’s a electric motor or an engine) and the rpm it is designed to run at. This information is essential because it confirms you’re pairing the pump with the correct driver and ensures the pump will operate at the speed that delivers the intended performance. Other details like the color of the housing are cosmetic and not used to verify drive compatibility, the year of manufacture isn’t a primary driver specification, and while some nameplates may include serial data, the most useful information for matching the drive to the pump’s requirements is the drive type and rpm.
