TUSTIN, Calif. (July 2)—Fluid Research Corp. has formed an alliance to exclusively distribute Toging, Germany-based ViscoTec GmbH's cavity pumps and dispensing equipment in North America. Fluid Research, headquartered in Tustin, was selected because of its product knowledge, reputation and established customer base, a ViscoTec official said. The cavity pumps use specially machined helical shafts inserted tightly in a double helix polymer body. As the shaft rotates, fluid is transported through the pump, the companies said. The pump design can handle a wide range of fluids, including volatile chemicals, silica-filled sealants, wastewater dredge, micro balloon-filled polymers, soldering paste and peanut butter, the firms said.
