Voltage: 230 V AC - 50 Hz. Max circulating capacity: 9550 L/hour. External connection thread diameter: 1 1/2"". The PowerMax pumps can be used in garden ponds and running water systems and can be combined with UBBINK Filtramax modular filters. HEP-High Efficiency Pump. AMS- Asynchronous motor system: Outstanding performance, yet extremely quiet. NSS-Cleaning-free system: A low maintenance solution resulting from a specially designed piping system with precisely engineered inlet openings, eliminating the need for maintenance-intensive filter sponges. TPS-Overheat Protection System: increased safety against overheating due to the built-in thermostat switch. CST-Ceramic Shaft: Thanks to the ceramic shaft, made using the latest technology, the low-sounding and quiet motor is capable of higher power output. All PowerMax pumps have energy-saving, very powerful and highly reliable motors. In addition, the complete range is suitable for dry installation. If the pump is installed outside the pool, it must be placed below the water surface level. To do this, the upper part of the casing must be removed and the accessory pipe must be connected to the inlet opening. PowerMax pumps can also be used in saltwater environments thanks to the ceramic shaft. The adjustable plinth (up and down) helps to ensure safe installation.
