Magnus-4 300 2.2kW 3 Phase Pump

Introduction

As a retailer of hot tub spare parts, I’m delighted to present the Magnus-4 300 2.2kW 3 Phase Pump – a powerful, mid-range solution engineered for commercial pools and demanding aquatic applications. This professional-grade pump delivers reliable performance with exceptional durability, making it an ideal choice for facilities requiring consistent water circulation without the higher power consumption of larger models.

Professional Performance

The Magnus-4 300 is designed for serious water management applications where dependability is paramount. Operating at an efficient 2.2kW, this three-phase pump strikes an excellent balance between performance capability and energy consumption. The pump maintains a consistent 1,450 RPM, providing steady water flow while avoiding the excessive energy demands of higher-powered units.

This pump excels in medium-sized commercial environments where continuous operation is required. Its thoughtfully engineered four-pin closure system on the pre-filter cover allows for quick and convenient maintenance access, minimizing downtime during servicing. The enclosed asynchronous motor with external ventilation ensures the pump maintains optimal operating temperature even during extended use periods.

Superior Construction

Durability forms the cornerstone of the Magnus-4 300’s design. The pump components – including the pre-filter body, pump body, base, and cover – are constructed from glass-fiber loaded polypropylene, offering exceptional resistance to pool chemicals that typically corrode standard materials. This specialized composition ensures the pump maintains structural integrity even in chemically aggressive environments.

The impeller is manufactured from Noryl, a high-performance engineering thermoplastic renowned for its dimensional stability and hydraulic efficiency. The mechanical seal features premium ceramic carbon components paired with AISI-304 stainless steel, creating a reliable barrier against water infiltration that extends operational life.

Every fastener and the motor shaft are crafted from AISI-304 stainless steel, providing superior corrosion resistance in chlorinated or salt water environments. The pre-filter basket, made from durable polythene, effectively captures debris before it can reach and potentially damage the impeller system.

Engineered for Reliability

The Magnus-4 300 incorporates an enclosed asynchronous motor with external ventilation, designed to maintain optimal operating temperatures during continuous use. With IP-55 protection grade, the motor is effectively sealed against dust and water jets from any direction, making it suitable for various installation environments.

The Class F isolation provides exceptional thermal resistance, allowing the motor to function efficiently at elevated temperatures up to 155°C (311°F). This robust insulation system extends the motor’s operational lifespan while ensuring consistent performance under varying conditions.

A particularly valuable feature is the pump’s dual frequency capability (50 Hz and 60 Hz), making it compatible with electrical systems worldwide. This versatility is especially beneficial for international facilities or regions with non-standard power infrastructures.

Maintenance Benefits

The Magnus-4 300 is engineered with maintenance simplicity as a priority. The motor bearings come pre-greased for life, eliminating the need for regular lubrication while ensuring quiet, smooth operation throughout the pump’s service life. The polycarbonate pre-filter cover with its four-pin closure system provides quick access for routine cleaning and maintenance.

Ideal Applications

This 2.2kW pump is perfectly suited for:

• Medium-sized commercial swimming pools
• Spa and wellness centers
• Hotel and resort aquatic facilities
• Advanced residential pool systems
• Water features with moderate flow requirements
• Aquatic therapy installations
