Seawater Magnetic Drive Pump: 150 230V/1 - code: SWM0150230 - Frigomar

Magnetic drive pump for seawater circuit (Frigomar)

The magnetic drive centrifugal pump Frigomar (supplier code SWM0150230) is designed for the management of the seawater circuit on nautical systems, typically used in marine air conditioning and in cooling applications via heat exchanger. The magnetic drive / sealless allows the transfer of motion to the impeller without direct mechanical connection, eliminating the classic rotating seal on the shaft.

This configuration is particularly appreciated in the marine field, where operational continuity and the reduction of interventions related to traditional seals are central aspects in onboard maintenance. The pump is suitable for supply 230 V single-phase and frequency ) at, in line with many nautical installations.

Operating principle: magnetic drive

The pump NH-150PS uses a magnetic drive:

• the external motor drives a magnet;
• the magnet drives the internal impeller without direct mechanical connection;
• there is no conventional shaft seal on the shaft.

In practice, the separation between the motor part and the hydraulic part reduces the critical points typical of solutions with a through shaft and mechanical seal, making the pump suitable for applications where simpler management of shaft leakage and more straightforward maintenance are desired.

Typical applications in the nautical field

This pump is used as a component of the sea water circuit to ensure the necessary flow for cooling via condenser/exchanger in marine systems. A commonly used application scheme example is:

Sea intake → sea water filter → NH-150PS pump → condenser/heat exchanger → overboard discharge

In this type of installation, the pump operates downstream of the sea water filter, helping to maintain a constant flow towards the exchanger. It is a typical configuration on marine air conditioning systems and on systems where sea water is used as the cooling fluid.

Operational advantages (based on sealless technology)

The choice of a magnetic drive pump is often linked to practical onboard needs. Based on the described construction principle, the commonly associated advantages of this technology include:

• No shaft leakage, since the classic rotating seal is not present;
• Greater reliability with seawater compared to solutions that rely on traditional mechanical seals;
• Reduced maintenance related to typical seal issues, with easier management over time.

These aspects are especially useful when the system is installed in tight technical spaces and when periodic interventions are to be limited, keeping the system efficient and tidy.

Usage and notes for installation/maintenance

General usage guidelines

The pump is intended for seawater transfer in marine cooling circuits. For regular operation, it is common practice to place it in a circuit with a seawater filter upstream, to limit the entry of impurities and debris that can affect the hydraulic part.

Connections and integration into the circuit

The model offers several connection options, useful for adapting to different system configurations:

• 26×26 mm hose connection
• 1" threaded
• 20A×20A fitting

During replacement or retrofit, it is advisable to check the type of connection present on the system and choose the solution most consistent with the pipes and fittings already installed.

Power supply

The indicated version is 230 V single-phase with frequency ) at. Before installation, it is appropriate to verify compatibility with the available onboard power supply and the existing electrical system, especially when replacing a pump with different characteristics.

Liquid temperature range

The reported liquid temperature range is 0–70 °C. For specific applications or particular operating conditions, it is good practice to follow the manufacturer's instructions and the maintenance procedures provided onboard.
