LPG Gas Transfer Pump

Description

The DB-65 multistage LPG gas transfer pump is a centrifugal and side channel pump designed for handling LPG (liquid gas) and liquids with high-differential pressure, low NPSH conditions, and up to 50% gas content. It features a horizontal configuration and utilizes a mechanical seal for shaft sealing without the need for cooling. The pump is specifically engineered for pumping from underground tanks, thanks to its ability to handle aerated liquids and its capability to operate under challenging suction conditions. The incorporation of a pre-compression turbine at the suction end enables the pump to achieve a remarkably low required NPSH, enhancing its performance in demanding suction scenarios.
