Description
Transform inadequate water pressure with the Pentair Nocchi Multi Evo-A 5-50M – a sophisticated multi-stage horizontal pump system that delivers exceptional performance for standard residential and light commercial installations.
Multi-Stage Performance for Everyday Excellence
The 5-50M employs advanced multi-stage technology to generate substantially higher pressures than conventional single-stage pumps. With 120 litres per minute flow capacity and 55 metres maximum head, this system comfortably supplies multiple simultaneous outlets – run showers, taps and appliances without pressure drop or performance compromise. The multi-stage design achieves this impressive output whilst maintaining superior energy efficiency, translating to lower running costs throughout the pump’s lifetime.
Perfectly Sized for Residential Applications
The 25-litre stainless steel pressure vessel provides the ideal balance between pump protection and compact installation footprint. This capacity suits standard residential scenarios perfectly – sufficient water reserves to prevent nuisance cycling during typical household use, whilst maintaining dimensions that fit comfortably in utility rooms, airing cupboards or garages. For most homes requiring pressure enhancement, the 5-50M’s accumulator size represents the sweet spot between performance and practicality.
Whisper-Quiet Operation
One of the 5-50M’s standout characteristics is its remarkably silent operation. Precision-engineered hydraulics and the horizontal multi-stage configuration eliminate the intrusive noise that plagues conventional pressure boosters. Install adjacent to living spaces without concerns about disturbance – the system operates with exceptional discretion, only the sound of flowing water reveals it’s working.
Intelligent Automatic Control
The factory-set pressure switch orchestrates completely hands-free operation. Open any tap or outlet and the system activates instantaneously, delivering water at consistent pressure. Close the outlet and the pump automatically stops. The 25-litre accumulator stores pressurised water, preventing pump activation for minor draws – a feature that dramatically extends pump life, reduces electricity consumption and eliminates constant starting and stopping.
Energy Efficiency
The 5-50M’s high-efficiency hydraulic system extracts maximum performance from its 0.95kW motor (230V 50Hz). Advanced multi-stage design means this pump achieves its impressive 120 L/min output whilst consuming significantly less energy than less sophisticated alternatives – genuine savings that accumulate substantially over years of operation.
Robust and Reliable
Quality materials and proven engineering ensure dependable service. Technopolymer impellers and diffusers resist corrosion whilst providing optimal hydraulic performance. The horizontal configuration ensures stable, vibration-free operation, whilst self-priming capability up to 7 metres suction head provides installation flexibility via break tank arrangements. Designed for clean water applications up to 50°C.
Installation Ready
The 5-50M arrives fully assembled and pre-wired, ready for immediate installation. Standard 1″ BSP female connections on inlet and outlet ensure compatibility with UK plumbing systems. Compact dimensions allow installation in restricted spaces, whilst straightforward electrical connections enable swift commissioning by qualified installers.
