SACI Magnus-4 300 – 3 HP Commercial Pool Pump

SACI Magnus-4 300 – 3 HP Commercial Pool Pump

The SACI MAGNUS-4 300 is a professional-grade self-priming centrifugal pump built for commercial and public swimming pools that demand reliable, high-volume water circulation day after day. With a 3 HP (2.2 kW) 4-pole IE3 motor running at ultra-quiet 1450 rpm, this pump delivers up to 62 m³/h — making it a trusted workhorse for public pools, water parks, hotel facilities, and large aquatic centres.

The SACI MAGNUS-4 300 is part of the acclaimed Magnus commercial pump family, engineered in Spain to the highest standards of durability and efficiency. Whether you’re handling the filtration circuit of a 25-metre competition pool or circulating water through a large leisure pool complex, this pump delivers consistent performance without compromise.

Tough Materials for Pool Environments

Pool chemicals, salt, and minerals are hard on equipment. That’s why the MAGNUS-4 300 is built with corrosion-resistant materials throughout:

• Polypropylene + fibreglass body — rigid, lightweight, and completely unaffected by chlorine, salt, or pool chemicals
• Noryl Noryl impeller — a tough, chemical-resistant engineering polymer perfectly suited for standard chlorinated pool water
• Stainless steel AISI-316 shaft and mechanical seal — marine-grade stainless for maximum longevity
• Stainless steel AISI-316 bolts and fixings — no rust, ever
• Large transparent pre-filter basket — easy visual inspection, quick to clean, protects the impeller from debris

Efficient 4-Pole IE3 Motor

The MAGNUS-4 300 runs on a premium IE3 asynchronous motor at 1450 rpm. IE3 is the highest motor efficiency class, meaning lower electricity consumption compared to older IE1/IE2 motors — a significant saving when running a commercial pump continuously. The 4-pole design means the motor is fully sealed with IP-55 protection and Class F insulation, with lifetime-lubricated bearings that require zero maintenance. There is no electrical contact between the motor and the water.

Easy Installation

The MAGNUS-4 300 connects via a 110 mm (4″) flanged inlet and outlet, making it straightforward to integrate into standard commercial pool pipework. The motor is rated for 230/400V three-phase, making it compatible with both standard 230V and 400V industrial three-phase supplies. Maximum operating water temperature is 40°C, and the stainless steel AISI-316 mechanical seal also makes this pump suitable for use with sea water.
