Sea water pump MD 200 230V/1/50-60 – code: SWM0200230 – Frigomar

The sea water pump MD 200 Frigomar (spare part code SWM0200230) is a component dedicated to seawater circuits in the nautical field, where a constant flow towards condensers and exchangers is required. The unit is based on pump PAN WORLD associated model NH-200PS and adopts technology with magnetic drive, a solution typically chosen to reduce the elements subject to wear related to rotating seals.

Operating principle: magnetic drive

The pump uses a magnetic drive, in which the transmission of motion occurs through magnetic coupling between the motor and the impeller. In practice:

• the external motor generates the magnetic field;
• the internal magnet drives the impeller;
• there is no rotating mechanical seal on the shaft.

Why this technology is used in seawater circuits

In circuits with seawater, the choice of a magnetically driven pump is often linked to reliability and maintenance management needs. In particular, the typical advantages of this solution include:

• reduction of the risk of shaft leaks, thanks to the absence of the rotating mechanical seal;
• good adaptability to circuits with seawater;
• reduced maintenance compared to traditional pumps with mechanical seals.

Applications on marine systems

The MD 200 pump is suitable for seawater circuits on marine systems, particularly for cooling of marine air conditioners and systems with seawater heat exchanger. In these systems, the pump helps maintain the necessary flow towards the condenser/exchanger, with final discharge overboard.

Typical functional diagram

Sea intake → seawater filter → MD 200 pump → condenser/exchanger → overboard discharge

Note on integration into the circuit

In a properly configured seawater circuit, the presence of the seawater filter upstream of the pump is a key element to limit the entry of impurities and reduce debris accumulation in the circuit. The pump thus works as a water moving element towards the exchanger and, downstream, towards the discharge.

Operational advantages (in maintenance and spare parts)

As a dedicated spare part, the Frigomar pump SWM0200230 is useful when you want to restore the proper functioning of the seawater circuit while maintaining a configuration consistent with the existing system.

• quick identification through spare part code and associated model;
• electrical consistency with 230 V single-phase power supply and 50/60 Hz frequency (always check the onboard system);
• magnetic drive solution for applications where it is preferable to avoid mechanical rotating seals on the shaft;
• connection flexibility thanks to the indicated attachment options (hose connection and threaded), to be chosen based on the circuit configuration.

Usage and important notes

For proper use in the nautical field, it is advisable to always verify the correspondence between spare part code, associated model and system configuration (connections, attachments, and power supply). During replacement or maintenance, some general good practices include:

• sea water filter check and periodic cleaning, to limit blockages and flow drops;
• attachment check (hose/threaded) and the condition of the pipes, to avoid leaks or air intake;
• power supply check (230 V single-phase) and correct electrical circuit protection according to the onboard system;
• downstream circuit check (heat exchanger/condenser and discharge), to identify any restrictions that may affect overall operation.

If you need to replace an existing pump, always compare the code SWM0200230 and the reference NH-200PS with what is installed onboard, to reduce the risk of connection or configuration incompatibility.
