March 2CP-MD 230 VAC Magnetic Drive Centrifugal Pump 0125-0058-0200

The March 0125-0058-0200 2CP-MD is a 230V, single-phase, submersible-only magnetic drive centrifugal pump designed for compact fluid-circulation applications. The 2CP-MD combines a sealless magnetic-drive design with a polypropylene wet end, making it a practical choice for compatible fresh water, salt water and mild chemical service where the pump can remain submerged during operation.

At 60 Hz, March rates the 2CP-MD for a maximum flow of 5 GPM and a maximum head of 13 feet. The pump uses a 3/8-inch FPT and 3/4-inch MPT inlet arrangement with a 1/4-inch MPT outlet, giving installers threaded connection options in a compact Series 2 package.

Sealless Magnetic Drive Design

Unlike a conventional direct-drive centrifugal pump with a rotating shaft penetrating the pump housing, the 2CP-MD transfers motor torque magnetically to the internal impeller. Eliminating the conventional rotating shaft seal helps reduce a common source of leakage and shaft-seal maintenance while keeping the motor side mechanically isolated from the primary wet-end rotating assembly.

Standard Wet End Construction

The standard 0125-0058-0200 configuration uses polypropylene front and rear housings and impeller, a Viton O-ring, stainless steel shaft, ceramic thrust washer and ceramic magnet. Because this model operates submerged, March also notes that epoxy, Buna-N and the electrical cord are exposed to the surrounding solution during operation.

Performance and Operating Conditions

The 2CP-MD develops up to 5 GPM and 13 feet of head at 60 Hz, with performance changing when operated at 50 Hz. March lists a maximum internal pressure of 50 PSI and maximum liquid temperature of 130°F / 54°C. The exact system operating point should be checked against the manufacturer pump curve rather than selecting the pump from maximum flow or maximum head alone.

Common Applications

March identifies marine air conditioning and fountains among the most common applications for the 2CP-MD. The pump has also been used with fresh water and salt water. Any application involving chemicals, elevated temperature, unusual specific gravity or viscosity should be evaluated for material and performance compatibility before installation.

Submersible-Only Installation

A critical distinction of the 2CP-MD is that it must be operated submerged. Buyers looking for a similar Series 2 pump for open-air operation should not assume that the 2CP-MD and LC-2CP-MD are interchangeable. Installation environment, voltage, hydraulic requirements and wet-end compatibility should all be verified before replacement.

Exact 230V Variant

Manufacturer part number 0125-0058-0200 identifies the 2CP-MD 230V complete standard pump. The related 0125-0058-0100 is the 115V version. Confirm the electrical supply and existing pump part number when replacing an installed unit.

For applications that match its operating envelope, the March 0125-0058-0200 offers a compact combination of submersible operation, sealless magnetic-drive construction and Series 2 serviceability for dependable fluid circulation.
