4 BLOCK- 4 Close-coupled submersible pumps

4 Block pumps are smart conventional borehole submersible pump designs with pump motor placed inside a steel casing to remain compact. Hydraulic and motor components are the same though they are encased in one piece casing thus providing a more economical alternative to the traditional borehole pump.

4 Block Pedrollo Pump Construction

• Pump Sleeve: Stainless steel AISI 304
• Shaft: Stainless steel AISI 304
• Impellers: Derlin®
• Diffusers: Noryl™
• Motor: Technopolymer
• Delivery Port: Stainless steel AISI 304

Features of 4 BLOCK Pedrollo Pump

• High resistance techno polymer hydraulic parts – capable of allowing light silt water to pass through the pump.
• Incorporated built-in capacitors eliminate the need for a separate control unit.
• 20 m drop cable – supplied as standard.
• Thermal protection – thermal overload for protection is provided so the pump can be connected directly to the mains power through a 10mcb fuse.

The 4 BLOCK/PRO100AR is ideal for all small-scale domestic needs, especially for boreholes but can also be suitable for wells with either vertical or horizontal installation.
