Following a two-year design and laboratory test phase and a further two years of field testing, the new generation of Franklin Electric’s 4-inch submersible motors was launched into the Southern African market last year.

The new design includes updated and user-friendly features such as full 304/316 stainless steel construction and reduced part count, clamped positive stop cable mount, flat cable with integrated earth lead and a replenishing valve that is accessible from the outside.

The Franklin Electric 4-inch submersible motor was first available in South Africa in 1972 and has since become the driving force behind residential and light commercial submersible pumps with some of the earliest installed pumps still in operation today. Lyon Van Der Merwe, Franklin Electric SA application engineering manager, says that the 4-inch NextGen submersible motor is remarkable for a number of reasons, but most notably for the fact that is has retained the same basic mechanisms and design elements for the past 30 years, proving that Franklin Electric does indeed supply quality pumps manufactured for the long haul.

“With the NextGen 4-inch low thrust submersible pump, Franklin Electric customers can expect even better results at the same competitive prices as before. If the previous motor design could exceed a lifespan of 30 years, just imagine what you can expect from the new generation design,” enthuses Van Der Merwe.

He adds that new developments on the pump concentrated on improving the electrical design of the motor, thereby increasing motor efficiency, lowering the motor temperature and extending the service life.

New features include:

- A full AISI 304/316 stainless steel construction and lower part count which has improved not only the look and feel of the pump but also the motor performance when used in slightly aggressive environments
- A new clamped positive stop cable mount that uses only 1 T25 hexalobular slot combination head screw that is torqued down to a positive stop with a well-defined torque of 3 – 4,5 Nm
- A novel plug sleeve design that accommodates a jacketed, 4-cored flat lead which significantly reduces the effort of water-tight splicing the motor short lead to the drop cable.
