March BC-3CP-MD-AM Magnetic Drive Centrifugal Pump 0130-0018-0700

The March 0130-0018-0700 BC-3CP-MD-AM is a sealless centrifugal magnetic drive pump powered by a compressed-air motor. Designed for compatible chemical recirculation, chemical transfer and process-fluid handling, this Series 3 pump combines March's magnetic-drive wet end with an air motor for installations where pneumatic power is preferred over a conventional electric motor.

March identifies 0130-0018-0700 as the complete standard BC-3CP-MD-AM pump. Burt Process and March air-motor documentation rate the model for up to approximately 10.5 GPM maximum flow and 42 feet maximum head, giving it substantially higher head capability than standard electric BC-3CP-MD configurations.

Sealless Magnetic Drive Operation

The BC-3CP-MD-AM transfers power from the air motor to the impeller through magnetic coupling. Because the motor shaft does not pass directly through the pump housing, the pump does not require a conventional rotating mechanical shaft seal. This design helps reduce seal-related leakage and maintenance in compatible chemical and process applications.

Magnetic coupling also keeps the motor-side drive components separated from the primary fluid-handling chamber while still allowing torque to be transmitted efficiently to the internal impeller.

Air Motor Power for Industrial Applications

Unlike AC or DC versions of the Series 3 pump, the BC-3CP-MD-AM uses compressed air as its power source. March documentation lists the standard air motor at approximately 1/8 HP, with the model requiring about 29 PSI air pressure and approximately 4 CFM under the listed operating condition.

An air-powered configuration can be useful in facilities where compressed air is readily available or where the application calls for a pneumatic drive instead of an electric motor. Actual pump output can vary with the supplied air pressure and airflow, so the compressed-air system should be sized appropriately.

Polypropylene, Viton and Ceramic Wet End

The standard wet end uses a polypropylene front cover, polypropylene encapsulated impeller and polypropylene rear housing, along with a Viton O-ring, ceramic thrust washer and ceramic shaft. These components form the primary fluid-contacting section of the pump.

March parts data identifies the front cover with a 3/4-inch FPT inlet, the rear housing with a 1/2-inch outlet, and ceramic internal support components. This material combination is commonly used in compatible chemical-service and industrial circulation applications.

Flow and Head Performance

The air-motor-driven BC-3CP-MD-AM is rated for up to approximately 10.5 GPM maximum flow and 42 feet maximum head. These values represent maximum hydraulic capability rather than a single simultaneous operating point.

For correct pump selection, the intended flow rate should be compared with the required total dynamic head and the applicable March pump curve. Air pressure and airflow supplied to the motor also influence actual pump performance.

Common Applications

The March BC-3CP-MD-AM is primarily intended for chemical recirculation and chemical transfer. It can also be considered for compatible industrial process systems where sealless magnetic-drive construction and air-powered operation provide practical advantages.

• Chemical recirculation systems
• Chemical transfer applications
• Industrial process-fluid circulation
• Scrubber and treatment systems
• OEM fluid-handling equipment
• Applications where compressed-air drive is preferred

Operating Conditions

March lists a maximum internal pump pressure of approximately 50 PSI and a maximum liquid temperature of approximately 190°F / 87°C for this configuration. These limits do not automatically establish fluid compatibility.

The suitability of the pump should be evaluated based on the actual chemical, concentration, temperature, viscosity, specific gravity and complete system conditions. The pump should also be installed and operated according to March guidance to avoid dry running or improper suction conditions.

Connection Configuration

The standard BC-3CP-MD-AM uses a 3/4-inch FPT inlet and a 1/2-inch MPT outlet. This threaded connection arrangement should be confirmed against the existing piping system when the pump is being purchased as a replacement.

Exact Model and Variant Selection

March manufactures multiple Series 3 magnetic drive pumps, including electric, liquid-cooled and air-motor configurations. These models can share similar wet-end architecture while using different drive systems and performance ranges.

0130-0018-0700 specifically identifies the standard BC-3CP-MD-AM air motor pump. March also lists modified versions, including configurations with alternate O-ring materials, so the complete manufacturer part number should be checked before ordering.

Why Choose the March BC-3CP-MD-AM?

For compatible process systems requiring compressed-air operation, sealless construction and higher Series 3 head capability, the March 0130-0018-0700 provides a compact industrial pumping solution with chemically resistant wet-end materials and serviceable OEM components.

Before installation, verify required flow, total dynamic head, available air pressure and CFM, connection sizes, liquid temperature and chemical compatibility to ensure the BC-3CP-MD-AM matches the intended application.
