Magnus-4 1000 7.5kW 3 Phase Pump

Introduction

As a retailer of hot tub spare parts, I’m proud to offer the Magnus-4 1000 7.5kW 3 Phase Pump – a powerhouse solution for commercial pools and high-demand aquatic systems. This industrial-grade pump combines robust construction with efficient performance, making it an excellent choice for facilities requiring significant water circulation capacity.

Engineering Excellence

The Magnus-4 1000 represents the pinnacle of pool pump engineering. Designed for continuous operation in demanding environments, this 7.5kW three-phase pump delivers exceptional performance while maintaining energy efficiency. The pump operates at 1,450 RPM, striking the perfect balance between powerful flow and sustainable operation.

What sets this pump apart is its thoughtful design that addresses the common challenges of commercial pool operation. The four-pin closure system on the pre-filter cover allows for quick maintenance access, while the enclosed asynchronous motor with external ventilation ensures reliable operation even under heavy loads.

Built to Last

Durability is at the core of the Magnus-4 1000’s design philosophy. The pump body, pre-filter body, base, and cover are constructed from glass-fiber loaded polypropylene, providing exceptional resistance to pool chemicals that typically degrade lesser pumps. This specialized material composition ensures longevity even in challenging chemical environments.

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

All screws and the motor shaft are manufactured from AISI-304 stainless steel, offering superior corrosion resistance even 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.

Optimized for Performance

The Magnus-4 1000 features an enclosed asynchronous motor with external ventilation, engineered to maintain optimal operating temperatures even during extended use. With IP-55 protection grade, the motor is well-shielded against dust and water jets from any direction, making it suitable for installation in various pool environments.

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

One of the pump’s most versatile features is its dual frequency capability (50 Hz and 60 Hz), making it compatible with electrical systems worldwide. This flexibility is particularly valuable for international facilities or areas with non-standard power supplies.

Maintenance Considerations

The Magnus-4 1000 is designed with maintenance simplicity 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.

Applications

This powerful 7.5kW pump is ideally suited for:

• Commercial swimming pools
• Water parks and aquatic centers
• Large luxury spas and hot tubs
• Aquaculture facilities
• Water features requiring high flow rates
• Hydrotherapy installations
