Pumping systems and solutions supplier Franklin Electric South Africa (FESA) has launched its new range of high-efficiency end-suction pumps for the agriculture and industrial markets.
The FPS S Series features a number of upgrades that will benefit the company’s consumer markets that include the light industry, air conditioning and marine sectors.
FESA product specialist Bryan Storrier says that the company’s major focus is on high efficiency in line with its continuous improvement programme, which will also benefit cost of operation and total cost of ownership.
Features of the new range include a new design for impellers and volutes and all impellers are manufactured using the lost-wax casting method.
In comparison to normal sand casting, the lost-wax process produces a smooth surface, which automatically increases efficiency. Lost wax also increases the repeatability that ensures all the components fit perfectly every time.
“Our standard impeller material is carbon steel with cataphoresis treatment and 304 stainless steel. The cataphoresis treatment used on the carbon steel impeller is an electric chemical coating process for metallic surfaces, widely used in the automotive industry because of its penetration and long life, whether as a priming coat or final painting,” explains Storrier.
Cataphoresis treatment is ideal where a high protection against weather conditions, alkali and diluted acids is required.
A new design of the bearing housing incorporates cooling fins that remove excess heat from the bearings and oil and, because of the high maintenance required on greased bearings, grease-lubricated bearings are no longer used.
“Even with the increase in efficiencies of up to 90% on some models, we are still able to market the pumps competitively against leading products in the industry and can offer our customers a pump that will save them money,” concludes Storrier.
