Publication number: 20040195186Abstract: A grease removal system includes a solid interceptor fluidly coupled to a grease trap tank, which is fluidly coupled to a secondary tank. The secondary tank contains an enzyme solution which biodegrades the grease. The grease removal system may also include a solid interceptor fluidly coupled to a grease trap tank which is fluidly coupled to a replaceable container. Grease is diverted from the grease trap tank into the replaceable container and thereafter discarded. The grease removal system may include a grease trap tank utilizing a unique arrangement of grease baffles and solids baffles which work together to isolate grease within a single region of the grease trap tank for ease of disposal. Finally, the grease removal system includes two level sensors which detect the level of grease within the grease trap tank and, at the appropriate level direct the accumulated grease from the grease trap tank.Type: ApplicationFiled: March 25, 2004Publication date: October 7, 2004Applicant: Zurn Industries, Inc.Inventors: Carl R. Nicolia, Joseph Tripodi, Douglas R. Wroblewski, Robert J. Burnham

Patent number: 6581626Abstract: A backflow prevention apparatus has a housing with an opening having a predetermined length. A first valve body, and a second valve body may be slidably sealed with one another, and compressed such that their combined length is less then the length of the opening. In the compressed state the valve bodies may be inserted within the opening of the housing and then elongated such that the ends of valve bodies engage and sliding seal with segments of the housing. A spacer may be placed between the first valve body and the second valve body to secure them within the opening. An intermediate valve body may be introduced between the first valve body and the second valve body.Type: GrantFiled: June 28, 2001Date of Patent: June 24, 2003Assignee: Zurn Industries, Inc.Inventors: Brad L. Noll, William M. Orr, Timothy W. Hurt

Patent number: 6467750Abstract: A unitary diaphragm assembly for use primarily in conventional flush valves. The diaphragm assembly has a flexible diaphragm which includes a sealing portion and a mounting portion at the outer peripheral edge. A flow ring is positioned adjacent the sealing portion of the diaphragm. An elongated barrel member extends from the diaphragm in a longitudinal direction and includes a plurality of radial guides positioned circumferentially around the outer surface of the barrel member along a portion of the length of the barrel member. The diaphragm defines an orifice having a ring portion that flexes when a pressure difference is applied across the orifice thereby increasing the flow rate across the diaphragm. The orifice has a smaller diameter at a first end relative to a second end of the orifice. A method of compensating for a pressure difference across the diaphragm is also disclosed.Type: GrantFiled: September 7, 2001Date of Patent: October 22, 2002Assignee: Zurn Industries, Inc.Inventor: William A.
