The pumps are designed to operate in temperatures ranging from -104°C up to +180°C. The material combination will for each order be selected in due consideration of the cargo list and the operating temperatures of the pumps.
The pumps are normally driven by an electrictic motor. If regulation of the RPM is required, a frequency converter or a hydraulic motor is optional.
Depending on the cargo the pumps can be equipped with an inducer for gases, a molasses worm screw for highly viscous cargos or stripping equipment with a flat valve in order to minimize the residue in the tank.
The pumps are normally delivered assembled ready for installation. The pumps are free to expand or contract as they are fixed to the dome flange and guided by a guide ring mounted on the tank top. Depending on the length of the pipe stack or potential slushing due to slacks tanks, it may be necessary to install one or more midsupports in order to avoid bending the pipe stack.
