Consulting-Specifying Engineer 2015 Product of the Year finalists: Plumbing and water management
Read about the four finalists in the Plumbing and Water Management category for the Consulting-Specifying Engineer 2015 Product of the Year program.
SKG Series submersible pumps offer newly engineered patent pending RAD-AX Dual Shredding Technology with radial and axial shredding. Engineered to obliterate flushable wipes in wastewater and industrial applications. Features high-torque 4-pole motor, robust construction. Available for 2-, 3-, and 5-hp submersible pumps. The pumps can shred a wide variety of municipal and industrial wastewater solids. The hardened impeller and plate materials provide maximum wear resistance for long service life. Hardened cast iron construction stands up to rough handling and pumping gritty water. Winding protection and (NEMA) Class F motor insulation allow motor temperatures to rise to 239 F.
M•Power sensor-operated faucets are suitable for high-traffic commercial spaces where prevention of disease transmission is of heightened importance. The hands-free faucets offer exceptional water savings and optimal hygiene protection. Updated models feature a sentinel flow option to purge the waterway 24 hours from last use and a cleaning mode that enables temporary sensor deactivation for cleaning and maintenance. Laminar flow kits are available for increased sanitary protection, ideal in health care environments. An optional temperature mixing lever is available on some models, allowing facilities to custom set their flowing water temperature. The lever also serves as a manual override for the sensor.
Lead-free, brass ball valves
ProPEX lead-free brass commercial ball valves are code-listed for PEX-to-PEX connections. The full-port valves are available in sizes of ½ to 2 in. and are listed to ASTM F1960, NSF 14/61, NSF 359, and the Uniform Plumbing Code. The valves feature blow-out-proof stems and are available with stem extension kits to accommodate up to 2 in. of insulation in insulated piping applications. In addition, both ends of the valves are manufactured with Uponor’s ProPEX fitting system for expansion connections that cannot be dry fit and hold tight with up to 1,000 lbs of radial force.
Stainless steel butterfly valve
The Series 461 stainless steel butterfly valve’s unique design of the offset disc and two-piece stem increases flow and reduces operating torque by up to 35%. The combination of stem bearings and a pressure-enhanced rubber seat keeps torque consistent over the life of the valve. The seat design seals equally on both sides of the valve, assuring full 360-deg sealing and minimizing long-term wear. This feature results in a longer life expectancy than most conventional valves. A patented cartridge design with redundant and replaceable stem seals increases reliability and ease of service.
