Latest company case about Rotary Lobe Pump and Multicrusher in a Tar Lake

Rotary Lobe Pump and Multicrusher in a Tar Lake


From a Tar Lake high viscose sludge needs to be disposed. Previously installed pump systems failed due to the high viscosity - temperature depending up to 50.000 m/Pas -- and the solids being included partially being relatively large. Both facts let the previous pumps clogging and block. The solution for that application was the Accuvon double pack, consisting of a Multicrusher HAP 80 and a Rotary Lobe pump AP 80, The machines are fitted to a common frame, but individually driven by hydraulic motors. The complete submersible unit is ex-proof and according to the European ATEX-Standard
