blue PRO Series

Electric Submersible Pumps

The bluePRO Series is intended for use in applications requiring high performance or prolonged, heavy-duty operation in domestic and residential contexts. Versions are available with four different hydraulics:

  • DRENO (DR bluePRO) with multi-channel open impeller for clear or slightly soiled wastewaters
  • DRAGA (DG bluePRO), with vortex impeller and large free passage for wastewaters with heavy soil
  • GRINDER (GR bluePRO), with cutter system
  • HIGH HEAD (AP bluePRO), with multi-channel open impeller and high head.

They are designed to provide optimal service with blueBOX lifting stations. Models with vertical discharge have a breather allowing them to be primed without touching the system even after the tank has been completely emptied.
All components are designed to deliver outstanding reliability and ensure quick, easy maintenance. Every model undergoes pressurised testing to guarantee perfect assembly and operation of the gaskets, cable gland and mechanical seals.

The cast iron structure and double mechanical seal in oil chamber make these models rugged and reliable and suitable for even heavy-duty applications lifting strained or soiled wastewater containing solids or filaments, in domestic and residential installations or small civil plants. Models available in IECEx certified version

Ergonomic handle styled for optimal grip. Shaped to take a shackle to hold the pump steady during handling.
Float switch stroke adjustment system for modification of start-stop levels.

Innovative cable gland system with cable holder system and twin O-ringsto ensure maximum tightness. Simpler extraction for maintenance.

Single-phase models have internal capacitor.

EN-GJL-250 cast ironconstruction guarantees solidity and durability even in case of maintenance requiring removal and replacement of the motor.

Stainless steel suction strainer and diffuser plate (models 50, 75 and 100). Techno-polymer suction strainer with cast iron diffuser plate and foot (models 150 and 200)[DR bluePRO]

Breather for venting the air accumulated inside the pump after the pit empties, ensuring reliable pump priming even after long periods out of use. [DG bluePRO] [DR bluePRO]

Stud bolt for closing the motor compartment for the pressurised testingevery model undergoes.

Two silicon carbide (2SiC)mechanical seals in oil chamber. The V-Ring in direct contact with the liquid protects the mechanical seals from foreign bodies to keep them in good working condition.

Guarantees longer mechanical seal lifetime and is easily accessible thanks to a patented system to simplify maintenance procedures.

Full free passageallowing the expulsion of solids up to 50 mm and preventing fouling of the impeller. [DG blue PRO]

Stainless steel diffuser plate. Ensures the expulsion of small suspended solids and prevents fouling of the impeller. [DR blue PRO]
