Magnus-4 400 3kW 3 Phase Pump

Introduction

As a retailer of hot tub spare parts, I’m pleased to offer the Magnus-4 400 3kW 3 Phase Pump – a robust and reliable solution designed for commercial pools and high-performance aquatic systems. This professional-grade pump delivers exceptional water circulation capabilities with the durability needed for demanding environments, positioning it as an ideal choice for medium to large facilities requiring consistent and powerful water movement.

Engineered Performance

The Magnus-4 400 represents a perfect balance of power and efficiency with its 3kW three-phase motor. Operating at a consistent 1,450 RPM, this pump delivers substantial water flow while maintaining energy efficiency for sustainable operation. The enclosed asynchronous motor with external ventilation ensures optimal temperature management even during extended operational periods.

What distinguishes this pump is its thoughtful design addressing the rigorous demands of commercial pool operation. The convenient four-pin closure system on the pre-filter cover enables quick access for maintenance, minimizing downtime and simplifying routine service tasks. This attention to practical design makes the Magnus-4 400 particularly well-suited for facilities where operational efficiency is paramount.

Durable Construction

The Magnus-4 400 is built with longevity as a core design principle. The pump body, pre-filter body, base, and cover are manufactured from glass-fiber loaded polypropylene, providing exceptional resistance to pool chemicals that typically degrade standard materials. This specialized composition ensures the pump maintains structural integrity even in the most chemically aggressive environments.

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

All fasteners and the motor shaft are manufactured from AISI-304 stainless steel, offering superior corrosion resistance in chlorinated or salt water environments. The pre-filter basket, constructed from durable polythene, efficiently captures debris before it can reach and potentially damage the impeller.

Reliability Features

The Magnus-4 400 incorporates an enclosed asynchronous motor with external ventilation, engineered to maintain optimal operating temperatures during continuous operation. 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 Advantages

The Magnus-4 400 is designed with maintenance efficiency in mind. 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 allows for quick and easy access during routine cleaning and maintenance tasks.

Ideal Applications

This powerful 3kW pump is perfectly suited for:

• Medium to large commercial swimming pools
• Aquatic centers and water parks
• Hotel and resort pool complexes
• Advanced hydrotherapy installations
• Water features requiring substantial flow rates
• Competitive swimming facilities
