Overview
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 end makes it possible to obtain a very small required NPSH, so that this pump can be used under very difficult suction conditions.
Application :
LPG cylinder filling ;Pumping LPG from underground storage ;Bulk filling operations ;Loading/unloading of bulk trucks and transport trailers;vaporizer feed pumps
