The Pedrollo 4BLOCK/PRO100AR is an innovative adaptation of the conventional 4SR borehole submersible pump design incorporating an integral pump/motor unit in one compact unit. Hydraulic and motor components are the same, though they are encased in a one-piece housing thus providing a more economic alternative to the traditional borehole pump. Particular features include:-

  • High resistance technopolymer hydraulic components providing the pump with a light silt passing capability
  • Integrated design incorporating a built-in capacitor so no separate control unit is required.
  • 20m drop cable supplied as standard.

The 4BLOCK/PRO100AR range is particularly suitable to all small-scale domestic installations particularly for boreholes, though they can also be used in wells in either vertical or horizontal configuration. All pump components other than the technopolymer impellers and diffusers are manufactured from AISI304 grade stainless steel.

Pumps are fitted with integral two-pole Pedrollo motors constructed principally from stainless steel. A built-in thermal overload for motor protection is provided so the pump can be connected directly to the mains power supply through a 10A fuse or MCB.
