German pump manufacturer HOMA has developed a submersible motor agitator for its HRS series with a new propeller design which prevents clogging.
Submersible motor agitators are often used in the homogenisation and suspension of fluids. However, stringy solid matter can cause clogging which poses a significant threat to these systems. If matter gets caught around the propeller, it cannot turn as it should and the centrifugal output of the agitator rapidly falls off.
In the submersible motor agitator for its HRS series, HOMA has focused on the ability of the hydraulic system to withstand such fibrous elements that fail to disintegrate. A new propeller design effectively prevents clogging and the stainless-steel construction is resistant both to corrosion and wear caused by abrasive elements.
The propeller was designed with the aid of a computer which allowed the company to conduct trials and detailed analysis of the results. This allowed HOMA to target, analyse and improve the weak points in the propeller. Once the data had been analysed, HOMA designed its eight- and twelve-pole systems to include investment cast propellers, which allow particularly good flow optimisation of the blades.
