Patent ID: 7384183

Claim:
An apparatus for mixing liquid decontaminants and dispensing a foam-based or liquid-based decontaminant, said apparatus comprising: a plurality of tanks capable of containing liquids; a pump assembly operating to drain and fill said plurality of tanks, said pump assembly having a plurality of pumps, wherein each pump is in communication with a respective tank, and each pump has a respective drive assembly, said pumps and said drive assemblies aligned in a linear, non-parallel arrangement; a plurality of couplings connecting each of said drive assemblies of said plurality of pumps to one another in linear series, said couplings and said drive assemblies coaxially aligned with respect to one another, said couplings and said drive assemblies arranged in an alternating sequence such that one each of said couplings connects in series two each of said drive assemblies; a motor directly connected in linear series to one end of one of said pumps, said motor further connected in linear series to said drive assembly of said one pump such that said motor engages said drive assembly of said one pump, initially drives one of said couplings connected to said drive assembly of said one pump, and further drives said drive assemblies of other said pumps and other said couplings a manifold in communication with said plurality of pumps and said plurality of tanks, said manifold for mixing liquids from said plurality of tanks; wherein said plurality of pumps are capable of drawing liquids from said plurality of tanks in defined ratios through said pumps to said manifold for mixing and dispensing; and wherein each of said drive assemblies and each of said couplings rotate coaxially with respect to one another.
