MAXIMA-4 250 - 2.5 HP three-phase electric pool pump
Flow rate up to 1000 l/min (60 m³/h). Head up to 12.5 m. 1.8 Kw (2.5 HP) motor.
The MAXIMA-4 250 self-priming electric pump by Pedrollo is recommended for use in commercial swimming pools up to 1080 cubic metres.
This pump is designed and built to be durable.
The MAXIMA-4 250 has a high resistance to heat and chemical and salt corrosion. The engine case is painted with cataphoresis treatment.
The base is made of anti-corrosion plastic material which ensures stable support for the pump and pipes.
A distinguishing feature of the MAXIMA-4 250 is the transparent pre-filter that facilitates visual inspection and the extra large basket that allows for reduced cleaning frequency.
This pump can be used for swimming pools with water that has a pH of 6.5 to 8.4.
The flow rate ranges from 200 to 1000 litres and the head from 4 to 12.5 metres.
The suction capacity of the MAXIMA-4 250 is up to 4 metres.
It must be powered by a three-phase voltage, has a horsepower of 2.5 HP and the liquid temperature reaches up to +40 centigrade.
The inlet and outlet ports are flanged, it is possible to connect the pump to the water system via a 110 mm 8-hole counterflange.
