Delivered complete with a 0.55kW 2-wire motor and 30-metre lead, the Pedrollo 4BLOCKm6/5 is a high-volume submersible pump for large domestic properties and small commercial irrigation projects. This 4BLOCK6/5 model features patented floating impellers that handle sand concentrations up to 200 g/m3 while prioritising flow capacity in 4-inch boreholes.
The 240V single-phase motor draws 4.4 Amps and delivers 31.5 metres of shut-off head with a maximum flow of 150 L/Min. Hydraulic performance is achieved through fully independent floating impellers that tolerate suspended solids without efficiency loss. The 32 mm discharge port connects to standard pipework, and the pre-installed 30-metre lead simplifies borehole installation.
Stainless steel AISI 304 construction provides corrosion resistance for long-term submerged operation. The non-toxic oil-filled motor is safe for potable water systems, with the power cord HRC certified for drinking water use. Noryl diffusers and Delrin impellers offer abrasion resistance in sandy groundwater conditions.
Weighing 12.0 kg, the pump features a compact 4-inch design for standard boreholes. The built-in motor capacitor simplifies electrical connections. Continuous S1 duty rating with Class F insulation and IP X8 protection ensures reliable performance up to 35°C.
