A drive motor of the pump drive, the gas seal column, and the pump may comprise a hermetically sealed, vertically-oriented, pumping system where the gas seal column is operable to replace mechanical seals around a drive shaft that couples the drive motor to the pump. A pressurized seal gas pumped into the drive motor and the gas seal column may displace corrosive fumes and the product being pumped. A product level may be sensed using a plurality of level sensors. Responsive to inputs from the level sensors, a seal gas control box may regulate the pressure of the seal gas using a plurality of valves. A bearing shaft adapter may be added to provide a special drive shaft of other lengths, diameters, or materials.

The present invention relates in general to the field of water pumps, and more specifically, to an attachment configured to connect to the rear wheel of a motorcycle or motorscooter to provide power to a water pump and a method of pumping water using the attachment. One aspect of the aquacycle pump includes a base plate and a kick-stand support bracket configured to slidably adjust so that the aquacycle pump may be compatible with different sizes of motorcycles or motorscooters. The aquacycle pump may further include a roller that is configured to abut against the rear wheel of the motorcycle or motorscooter. The aquacycle pump may further include a water pump, wherein the water pump is connected to the roller. The aquacycle pump is configured such that as the engine of the motorcycle or motorscooter is started and power is provided to rotate its rear wheel, the abutting roller of the aquacycle pump also rotates. The rotation of the roller, in turn, operates the water pump to convey water to a location where water is needed. The purpose of the invention is to provide a device and method that may utilize existing motorized vehicles prevalent in developing countries (e.g., motorcycles, motorscooters), instead of electricity or petrol generators, to provide energy to a water pump for delivering water.
