the DB-65 multistage pump,centrifugal and side channel is designed with 6 stages having a horizontal configuration,shaft sealing by mechanical seal without cooling for handling LPG(Liquid gas) the liquids involving high-differential pressure,low NPSH conditions and aerated liquids up to 50% gas such as pumping from underground tanks The use of a pre-compression turbine at the suction en makes it possible to obtain a very small required NPSH,so that this pump can be used under very difficult suction conditions
