The Emaux E-Power Pump is a heavy-duty, high-performance swimming pool pump designed for residential and semi-commercial pools where strong, reliable water circulation is required. Available in EPH300 3.0HP and EPH400 4.0HP models, this pump range is built for larger pool systems, higher flow requirements and demanding filtration applications.
Designed as a self-priming pool pump, the E-Power range can self-prime up to 2.5 metres above water level, making it suitable for installations where the pump is positioned slightly above the pool waterline. The pump features a 5-litre strainer basket, helping to capture debris before it reaches the filtration system, while the ring-lock seal design helps reduce suction leaks and improve suction efficiency.
The Emaux E-Power Pump is built for durability, using a 316 stainless steel shaft and 316 stainless steel mechanical seal for improved corrosion resistance in pool environments. It also includes IPX5 waterproof protection, built-in thermal protection, and overload protection to support safe and dependable operation.
This is not a small domestic pump. The EPH300 and EPH400 are suited for pool owners, installers and facilities that need higher flow, stronger suction and a more robust pump platform than standard residential models.

The Emaux EPH300 and EPH400 E-Power Pumps are ideal for:
- Large residential swimming pools
- Semi-commercial pool systems
- High-flow filtration setups
- Pools with larger pipework requirements
- Pool installations requiring strong suction and reliable circulation
- Applications where a standard domestic pump is undersized
For larger pools, flow matters. Undersizing a pump can lead to poor circulation, weak suction and underperforming filtration. The E-Power range gives you the muscle needed for more demanding installations.
