This is overcome by a set of SKF conical roller bearings. The high maximum discharge pressure results in very high axial forces on the bearings. In order to withstand this pressure and the wear caused by abrasive media, the plate wheel is specially designed: A high-tensile steel core carries easily replaceable sectional discs of polyethylene. Inside the DESMI DOP pump the pressure is built up between the screw and the engaging plate wheel. The vertical design means that the pump medium is forced into the pump by means of the end of the screw. The DESMI DOP pump is in its basic design a modified Archimedes' screw pump. WARNING! When using the pump in hazardous atmospheres, always follow the instructions in section 4.4. Examples of applications are:Įmergency off-loading of heavy crude, bunker oil or emulsions Transfer pump in oil recovery systems (Skimmers) Cleaning of oil pits Emergency fire fighting Auxiliary discharge or ballasting Emergency bilge pumping Nevertheless the pump will handle any medium very gently, without mixing or emulsifying e.g.

It is designed for handling liquids of an extremely high viscosity, like heavy crude oil or molasses, as well as low viscosity liquids as diesel fuel or water and it will cope with debris normally found in oil spill sites. The DESMI off-loading pump, see dimension drawing and assembly drawing in the appendix, has been specially developed for a wide range of emergency and auxiliary pumping operations.
