摘要:
A submersible pump-motor assembly (10) for use in dispensing petroleum from petroleum storage tanks (12). The pump-motor assembly (10) of the present invention enhances the performance characteristics of the pump-motor assembly (10) by providing greater flow area around the motor stator (59) while maintaining the alignment of the assembly's critical pump components. A shell (56) having an expanded portion (58) encloses the pump assembly (54) and the motor unit (52). The expanded portion (58) of the shell is disposed around the motor stator (59).
摘要:
A submersible pumping system is disclosed for pumping cryogenic liquid from a reservoir (1) in which an electrically powered motor /pump unit (34/32) is located in an operative position at the bottom of a fluid transmitting casing (14) in the reservoir (1). The motor/pump unit (34/32) is electrically connected to a power source and to ground by means of flexible electrical and ground conduits (62/64), and is raised and lowered through the casing by means of support (56) and lift cables (76). The flexible conduits (62/64) and support cable (56) are arranged within a flexible sheath (60) to thereby provide a multi-strand cable which is separated from the lift cable (76) by detachable brackets (80).

A refilling pump arrangement comprises a refilling hose (1), and a pump (2) mounted at the end of the hose. This arrangement provides the pump for refilling as part of the hose. This hose and pump assembly can be stored anywhere, either on or off a vehicle, and when stored on the vehicle, it can be stored in an area that does not need to be adjacent the liquid tank. This enables space savings for the parts of the vehicle which have the most critical space demands.

The invention relates to a container system comprising a container (1) with an integrated pump mechanism (11) of a submersible pump, particularly a drum pump or a container pump with a pump lance (12). This pump lance can be inserted into the container (1) via a bunghole (5), and a rotor shaft (13), which has a pump rotor (15) mounted thereon in a rotationally fixed manner and which is actively connected to a drive motor (31), extends through said pump lance. By virtue of the fact that the submersible pump has a pump head and a pump mechanism (11), which are designed so that they can be separated from one another, and a withdrawal connection is assigned to the pump head (25) that can be removed from the pump mechanism (11), the invention ensures that the container (1), which is advantageously provided with a bunghole (5) that is drawn deeper or is otherwise situated lower, forms, together with the pump mechanism (11) integrated in the container (1), a stackable and transportable unit that can be sealed tightly. The invention is for use in SCR technology or AdBlue® technology.
