SMC Pumps

A bare shaft pump is a type of pump that is sold without a motor or driver—it includes only the pump assembly itself. It’s designed to be connected to a separate drive system, such as an electric motor or diesel engine, via a coupling or pulley.

🔧 Key Features:

• Pump only: No motor, baseplate, or drive included.

• Customizable: Users can select their preferred driver, coupling, and mounting configuration.

• Common types: Centrifugal, gear, screw, or diaphragm pumps.

• Mounting: Typically requires alignment and mounting onto a baseplate with a compatible motor or engine.

📦 Typical Contents of a Bare Shaft Pump Package:

• Pump casing and impeller

• Shaft and bearings

• Seals or packing

• Flanges or threaded ports

⚙️ Common Applications:

• Water treatment plants

• Agriculture and irrigation

• Industrial process systems

• Oil & gas

• Mining and slurry transport

✅ Advantages:

• Flexibility in choosing the driver

• Often lower initial cost compared to complete pump sets

• Easier integration into existing systems

⚠️ Considerations:

• Requires separate motor selection and proper alignment

• Not plug-and-play—needs installation expertise

• Compatibility (torque, RPM, mounting) must be carefully checked
