Pumping Apparatus For Shear-Sensitive Fluids
US Patent:
2009001, Jan 8, 2009
Filed:
Jul 3, 2007
Appl. No.:
11/825088
Inventors:
Dale E. Donovan - Pittsburgh PA, US
International Classification:
F04B 17/00
US Classification:
417 53, 417392
Abstract:
Pumping systems for pumping shear-sensitive fluids between first and second reservoirs. In various embodiments, the pumping system may include a portable platform that supports at least one diaphragm pump thereon. The diaphragm pumps are arranged for fluid communication with first and second reservoirs. Valve arrangements may be provided that enable the shear-sensitive fluid to be pumped from a first reservoir to a second reservoir. In some embodiments, the valve arrangements enable the user to reverse the flow direction to enable the fluid to be pumped back out of the second reservoir into the first reservoir if too much fluid was initially transferred into the second reservoir. Other embodiments may employ a hand activated nozzle to discharge the pumped fluid.
