March BC-2CP-MD 12 VDC Magnetic Drive Centrifugal Pump 0125-0123-0100

The March 0125-0123-0100 BC-2CP-MD is a 12V DC brushed-motor magnetic drive centrifugal pump designed for compatible circulation and transfer applications. This configuration combines the compact March Series 2 wet end with a low-voltage DC motor, making it suitable for systems where 12V DC power is available.

Sealless Magnetic Drive Operation

The pump transfers motor torque through magnetic coupling to the internal impeller rather than using a conventional rotating shaft seal. This sealless construction helps reduce mechanical seal maintenance and isolates the primary wet end from a direct motor shaft penetration.

Series 2 Wet End Construction

The standard BC-2CP-MD configuration uses a polypropylene cover and rear housing, Viton O-ring, ceramic thrust washer and shaft, and an encapsulated polypropylene impeller. The standard configuration also uses a 0.250-inch bore drive magnet.

12V Brushed DC Motor

March identifies part number 0125-0123-0100 as the BC-2CP-MD 12V brushed complete standard pump. The related 24V brushed configuration uses a different product code and motor, so system voltage should always be confirmed before replacement.

Serviceable Brush Motor

March lists replaceable motor brushes for the compatible 12V and 24V brushed BC-2CP-MD configurations. This provides a service option for the motor assembly when brush wear occurs instead of automatically replacing the complete pump.

Chemical and Process Applications

Series 2 magnetic drive pumps are commonly used for compatible chemical recirculation, chemical transfer, process circulation, equipment cooling and other OEM fluid-handling applications. Suitability depends on hydraulic requirements and chemical compatibility of the wetted components.

Selection Guidance

Confirm the required DC voltage, flow and head, inlet and outlet configuration, fluid chemistry and existing March part number before ordering. For a direct replacement of the standard 12V brushed BC-2CP-MD, 0125-0123-0100 is the identifying manufacturer SKU.
