Materials and construction
The pump casing, shaft with coupling, suction strainer and cable cover are made of stainless steel, the suction and discharge body from precisely cast AISI 304 steel. The impellers and diffusers are made of technopolymer, the stage bodies are made of AISI 304 steel and the check valve is made of AISI 304 steel with NBR sealing. The 4OL motor has bearings lubricated and cooled by food-grade liquid, a flexible stator in a casing made of AISI 304L steel and a mechanical seal of carbon/ceramic. The hydraulics achieve an efficiency index MEI ≥ 0.4.
Installation and operation
The pump is installed vertically, for horizontal installation the manufacturer recommends a cooling jacket. The water must be clean and non-aggressive, with a temperature of 0 to +40 °C and a sand content of up to 150 g/m³; submersion is possible up to 250 m and the pump may start up to 20 times per hour. The motor can withstand operation with a frequency converter in the range of 30–50 Hz. Protection of the three-phase motor is provided by the user in the electrical installation. The electrical connection must be done by a qualified electrician.
