Cooling sleeve kits for Franklin Electric submersible motor pumps

Franklin Electric is expanding its portfolio of accessories and now offers cooling sleeves for all Franklin Electric motors.

The heat loss generated by the submersible motor must be dissipated to the pumped medium by means of convection.

If the minimum cooling speed along the submersible motor cannot be guaranteed, it is mandatory to install a cooling sleeve to generate sufficient cooling. Inadequate cooling can have various causes, such as a well diameter that is too large, the application in “open” water, insufficient flow rate or water inflow from above (top feeding).

To provide cooling, the pump-motor unit is supplemented by a cooling sleeve. This separate „sheet metal jacket” is sealed above the pump inlet. The pumped medium is thus sucked in from below and directed past the motor to dissipate the generated motor heat loss (convection).

Cooling Sleeve 4 Inch

Appropriate brackets and inlet strainers are available for horizontal installation.

Kit components:

1              Cooling sleeve tube (Stainless steel)
2              Pump sealing ring (EPDM) with drinking water approval
3              Motor spacer
4              Pipe clamps
5              Filter strainer (accessories)
6              Console (accessory for horizontal mounting)

Design change 6CT Motor Packaging


Optimizing of the packaging for the 6" encapsulated motors

To optimize the handling and shipment of the 6" encapsulated motors, we have optimized the packaging concept of the motors.

The motor packaging has been complemented with a single wooden pallet. This will change the height of the package by 136 mm. The width and length of the packaging are the same as before.

This improvement will facilitate the transport, handling and storage logistics of the motors, particularly in the case of heavy motor weights. 


Packaging design

This is a running change since Q3/2021.

Sandfighter EN

All 8" encapsulated submersible motors now equipped as standard with the exclusive Sand Fighter® Sealing System of Franklin Electric

All 8" encapsulated submersible motors now feature Franklin Electric's proven SandFighter® sealing system with SiC/SiC mechanical seal and sand protection as standard. The changeover for these motors will occur with the 2021 production date.

The technology is thus integrated as standard in all 6" to 12" Franklin Electric submersible motors.


Sand Fighter® Sealing System
The technology enables smooth operation in applications with higher levels of sand.

FE Selection tools


800 x 420 px FE select EN

We are pleased to announce the launch of FE Select EMENA, a digital selection software tool that simplifies product selection, configuration, and quoting. This online tool guides you through the process from start to finish, requiring only the basic application data, such as flow and head demands, to size many pumping systems. The software properly matches the components necessary for the desired application, provides specific data sheets and offers links to related informational product documentation.

 Features of FE Select:

  • 24/7 accessibility
  • A quick export option that allows to simplify the quotation request
  • Simple software navigation

Starting from today, FE Select is available for Vertical Multistage pumps.


Selection tools Franklin Electric EMENA:

More products will be added over time to FE Select. The link will be displayed on the applicable product pages on the website By clicking on this link you can easily start the selection process.

In addition to FE Select, we will continue to utilize our current Pump selector software for Etech products and High

Efficiency System Selection and Payback Tool until they will also be integrated into the new FE Select software at a later date. To visit our comprehensive Pump Selection page, click here.

Material improvement of 6" and 8" Stainless steel submersible pumps


800 X 420 Px Submersible Pumps Drinking Water Approvals EN

Due to increased demand for drinking water certified submersible pumps, Franklin Electric introduces several changes to the 6" / 8" pump series to ensure certification by major European drinking water authorities.

All changes listed below will be effective in production starting from July 2021. The part numbers of the pumps will not change. 

Materials approved for drinking water applications:


All rubber parts will be changed to drinking water approved materials. The rubber material of the O-rings and bearing bushings will be changed from NBR/HNBR to EPDM. This enables the rubber compounds to be approved for DM174, WRAS, UBA, ACS and NSF certificates.

The EPDM material has a hardness comparable to NBR/HNBR and allows a maximum working temperature of + 90 °C for all material pump variants. The material NBR with a maximum pump operating temperature of + 60 °C is still available on request.


The material of the upper journal sleeve bushings changes from ceramic-coated stainless steel (with chromium content) or Tungsten Carbide (Widia) to Aluminum Oxide. The intermediate journal sleeve is also changed from Tungsten Carbide to Aluminum Oxide. Tests in our laboratories have shown that the mechanical performance requirements of the new sleeve are guaranteed and that it is comparable to the two current options.

Alumina guarantees good thermal stability and excellent corrosion resistance, both in acid and alkaline environments. In addition, the material offers good oxidation resistance, very good hardness and excellent wear resistance.


Improved mechanical features


For the radial models, the material of the wear rings is changed from PTFE to PPS. The new type of wear ring is 100% compatible with the current diffusers. In addition, the PPS component is less affectable to temperature variations and has better dimensional tolerance than PTFE. These properties have been confirmed by laboratory tests since 2016, as this material has already been successfully integrated in other products.
