P Series

Electric Submersible Pumps

Reliability and strength are the main characteristics of the P series models, designed for heavy-duty civil, professional andindustrial applications.
The oil-bath motors guarantee a long working life even with heavily soiled and dense liquids. The set of three mechanical seals in an oil chamber ensures trouble-free operation and low maintenance requirements.
The wide choice of impellers allows these units to be used for a wide range of applications, from lifting clean water for irrigation and drainage to the transfer of heavily soiled wastewaters to municipal drains in the civil and livestock farmingsectors.

They are available with:

  • vortex impeller (DGP) with ample free passage, recommended for use with soiled liquids;
  • multi-channel open impeller (DRP), intended mainly for lifting sludge and dense liquids;
  • single-channel closed (SMP) and dual-channel closed (SBP) impellers, suitable for conveying sludge and sewage;
  • with grinding system (GRP), suitable with fibres andfilaments ;
  • with high head (APP) are suitable for use in mainly clean and slightly sandy liquids when a high pressure level is required.
Each model undergoes dual pressurised testing at the end of the line to ensure that the motor compartment is airtight and the mechanical seals have been correctly fitted, to guarantee excellent reliability.

Details

Two mechanical seals in silicon carbide (SiC and one in alumina graphite (Al) to guarantee maximum reliability even in heavy-duty applications.

Oil-bath motor for effective cooling to allow even heavy-duty workloads. Thermal protection devices incorporated in stator.

Shielded ball bearings with lifetime autolubrication.

Inspectable oil chamberto guarantee longer mechanical seal lifetime.

Ample free passage allowing the expulsion of solids and preventing fouling of the impeller.[DGP - DRP - SMP - SBP]

The special design of the hydraulic part ensures the expulsion of solids and prevents fouling of the impeller.[GRP - APP]
