This type of pump is mounted directly to supports in the bottom of a storage tank. In addition, it is connected to a discharge pipe that extends to the top of the tank and out to the discharge piping. This simple, low cost design is used in liquefied gas carriers. It is also used in other applications where a normal or required process includes removing the liquid from the tank for maintenance. As a result, this can be accomplished without excessive costs to the tank or system.

This pump and suction vessel is an integral part of the piping system and includes external suction and discharge connections. Mounted to the top or headplate of the vessel this ensures that the pump, motor and fluid product are totally contained within the pressure vessel. As a result, shaft seals are eliminated. The pump inlet is below the suction vessel inlet. So this allows the source tank liquid levels to be lowered to a minimum.

Removable, or in-tank pumps offer the advantage of overhead removal and installation. without taking the tank out of service. The pump operates at the bottom of a purpose-built pump column, through which it is installed and removed. The column provides the fluid discharge from the pump to the top of the tank and contains the lifting cables as well as the power cables. Our ZEN (Zero Enabled NPSH) inducer was specially developed to allow the pumps to reduce liquid levels to extremely low levels.
