Optimex has been offering canned motor elbow pumps for several years now. These pumps are especially designed for pumping applications with high flow rates and low heads.
Replacing the mechanical seal by canned motor technology provides a complete leakage free pump. This not only makes the system safe and reliable, but also reduces the amount of maintenance.
Thanks to our expertise and ingenuity in offering highly technical machines that often do not exist on the market, one of our customers entrusted us with the task of finding a solution for one of its helical drive pumping units where its abrasive product was damaging the mechanical seal.
We opted for a RETROFIT with a canned motor drive and circulation with an injection to eliminate failures.
The challenge of the design of this propeller pump was the axial thrust management as well as the calculation, design and material study for sizing the slide bearings which have to withstand high radial loads.
This last brand-new model is leaving our workshop and will soon be installed in a chemical plant in China to convey organic liquid effluents (2200m3/h @ 3m).
