LPG Transfer Pumps
DB-65 Side Channel Multistage Pump
6-Stage Horizontal LPG Transfer Pump
The DB-65 multistage pump, centrifugal and side channel, is designed with 6 stages, horizontal configuration, shaft sealing by mechanical seal without cooling, for handling LPG, liquids involving high-differential pressure, low NPSH conditions and aerated liquids up to 50% gas — such as pumping from underground tanks. A pre-compression turbine at the suction end delivers a very small required NPSH, allowing use under very difficult suction conditions.
