Pentair Waterpress Multi Evo-A 5-50M+ Single Pump Automatic Booster

Experience premium water pressure boosting with the Pentair Nocchi Multi Evo-A 5-50M+ – an advanced multi-stage system featuring an enlarged 60-litre pressure vessel for larger properties and high-demand installations where performance and longevity cannot be compromised.

Enhanced Capacity for Demanding Applications

Whilst the 5-50M+ delivers the same impressive 120 litres per minute at 55 metres head as its 25-litre counterpart, the enlarged 60-litre stainless steel pressure vessel transforms its operational characteristics. This substantial accumulator capacity provides significantly greater water reserves, dramatically reducing pump cycling frequency even during extended usage periods. The result? Enhanced pump longevity, reduced energy consumption and superior performance buffering during peak demand scenarios.

Ideal for Larger Properties

The 5-50M+ is the intelligent choice for substantial residential properties, commercial premises or any installation where multiple outlets may operate simultaneously for extended periods. Larger homes with 4+ bathrooms, properties with washing facilities, or commercial installations benefit enormously from the 60-litre vessel’s ability to supply sustained demand without constant pump activation. The additional accumulator capacity delivers a tangible performance advantage in real-world high-usage scenarios.

Maximum Pump Protection

The enlarged pressure vessel provides exceptional pump protection by storing substantially more pressurised water. This means the pump activates less frequently, even during typical daily use – each start cycle represents wear, so fewer starts equals extended pump life. For installations where reliability is paramount or where pump replacement would prove particularly inconvenient or costly, the 5-50M+’s enhanced protection credentials offer genuine peace of mind.

Multi-Stage Excellence

Advanced multi-stage hydraulic design generates the system’s impressive output whilst maintaining superior energy efficiency. The 0.95kW motor (230V 50Hz) delivers 120 litres per minute and 55 metres head – performance that comfortably handles multiple simultaneous outlets without pressure drop. Whether supplying showers, baths, washing equipment or irrigation systems, the 5-50M+ maintains consistent delivery across all applications.

Whisper-Quiet Operation

Precision engineering ensures remarkably silent operation – a crucial advantage in residential or light commercial settings where pump noise proves problematic. The horizontal multi-stage configuration and high-efficiency hydraulics eliminate the intrusive sounds associated with conventional pressure boosters, allowing installation in utility rooms, plant rooms or even garage spaces adjacent to occupied areas without disturbance concerns.

Intelligent Automation

The factory-calibrated pressure switch provides seamless automatic operation. Open a tap and the system responds instantly; close it and the pump stops. The 60-litre accumulator’s substantial reserves mean the pump won’t activate for minor draws or brief water usage – it intelligently waits until genuine demand requires its intervention, dramatically reducing unnecessary cycling and associated energy waste.

Commercial-Grade Reliability

Quality materials and robust engineering ensure dependable performance in demanding applications. Technopolymer impellers and diffusers resist corrosion whilst delivering optimal hydraulic efficiency. The horizontal configuration ensures stable, vibration-free operation even during extended run periods. Self-priming up to 7 metres suction head provides installation flexibility via break tank arrangements.

Professional Installation Package

The 5-50M+ arrives fully assembled, pre-wired and factory-tested – a complete pressure boosting solution ready for immediate commissioning. Standard 1″ BSP female connections ensure compatibility with UK plumbing installations, whilst straightforward electrical connections enable swift installation by qualified personnel.
