Maximum head: up to 90 metres.
Pumped liquid: clean, free of solids and abrasives, non-viscous, nonaggressive and chemically neutral, with properties similar to water.
Liquid temperature range: from 0 °C to +35 °C.
Maximum permitted amount of sand: 30 g/m3.
Discharge port diameter: 1” GAS.
Inverter supply tolerance: +10 % / -20 %.
Max. starts: 20/h.
Maximum motor supply frequency: 110 Hz (~6300 r.p.m.)
Installation: in 3” wells or larger, tanks and cisterns, vertical position.
In case of horizontal installation, ensure a minimum load on the thrust assembly.
