Abstract
Provided is a mobile fluid pumping system which may include a reservoir and, a pump actuated by a reversible motor. In the first configuration, the reversible motor is operated in a first direction causing a fluid to flow in a first direction and operated in a second direction causing fluid to flow in a second direction thereby providing means to fill a reservoir and then transfer fluid from the reservoir to a vessel or tank. The fluid delivery device provides means to substantially evacuate fluid from any connectors in the system thereby avoiding problems otherwise associated with remaining fluid that may freeze. Further, the device is designed to provide a closed load and unload system meeting ISO 022241.
Claims16
A mobile fluid pumping system comprising a pump having a reversible motor, said motor operating in either a first direction or a second direction, a tank, a first connecting member providing fluid communication between the pump and the tank, a reusable stainless valve (RSV) quick coupler compliant with the ISO 22241-3:2008(E) quality standard and configured to provide association with said connecting member said first connecting member defining a single route, said route providing direct fluid communication in either direction from said reversible motor, the reversible motor operating in the first direction causing a fluid to move through said single route in the first direction toward the tank, and the reversible motor operating in the second direction causing fluid to move through the single route in a second direction away from the tank, said system providing a closed load and unload system.
A mobile fluid pumping system comprising a tank, a reversible flow path comprising a connecting member extending from the pump, and means to cause fluid to flow wherein said fluid comprises DEF, said means to cause fluid to flow comprising a pump and a reversible motor, the reversible motor operating in the first direction causing a fluid to move in a first direction into the tank and the reversible motor operating in a second direction causing said fluid to move in a second direction out of the tank said tank and the pump in fluid communication, a valve compliant with the ISO 22241-3:2008(E) quality standard and a nozzle, said connecting member comprising a single, reversible route for loading DEF into and unloading DEF out of the tank.
An assembly for providing a mobile fluid tank, said assembly comprising a closed system having a pump, a reversible motor, a tank, and a single connecting member including a first end in direct fluid association with the pump which is in fluid communication with the tank, and a second end in fluid communication with an external structure wherein said fluid association comprises a valve compliant with the ISO 22241-3:2008E quality standard and facilitates flow of fluid in a first direction through said connecting member to said tank during the motor's forward operation and in a second direction from said tank back through said connecting member to said external structure during the motor's reverse operation wherein said reversible motor comprises a direct current motor.
A mobile fluid pumping system comprising a tank, a single, reversible flow path, and means to cause fluid to flow wherein said fluid comprises DEF, said means to cause fluid to flow comprising a pump and a reversible motor and a closed system, an ISO 22241-3:2008(E) compliant coupler associated with a connecting member;
- said tank and the pump in fluid communication, said reversible flow path comprising a portion of the path between the pump and the tank, the connecting member extending from the pump to an external structure separately mobile from the tank, said portion of the path and connecting member comprising the single, reversible flow path for loading or unloading DEF between the tank and an external structure, said flow reversed with the direction of the motor.
