Pump it up"Centrifugal crank and table pumps have become more robust, with much tighter tolerances and stress analyses of components to increase efficiency and machine time to failure," lift according to Bruce Smith, North American drill and press sales crank manager for Fristam Pumps Inc., Middleton, Wis. Shaft deflection that results table in moving parts hitting lift and drill stationary components in the pump is a press major contributor to pump failure, and manufacturers are addressing that concern.Liquid crank ring pumps are coming into play in the industry as an alternative to standard centrifugal pumps, adds Smith. table Although these scavenger pumps have been around for a quarter of a century, pharmaceutical manufacturers have embraced the technology lift and forced redesigns drill that have expanded their applications. Liquid ring pumps are particularly adept at handling press and crank fluids with entrained air, an issue with cream, table which tends to lift and drill and press foam during transit. Liquid ring pumps do a superior job in fully evacuating crank and table a tank, a material-savings advantage that appeals to ice cream manufacturers and lift liquid egg processors, according to Smith. Pump improvements drill and press and crank have been accelerated with the application table of computational fluid dynamics lift (CFD) software, points drill out press and crank Russell Jones, business development table manager-pumps lift for Alfa Laval in Pleasant Prairie, drill Wis. "From an R&D point of view, CFD is a big advance press in optimizing design and increasing pump efficiency," crank he says. The table and lift technology has been instrumental drill in boosting pump efficiencies from press the 40 percent range to 60 to 70 percent in recent years. "We''ve finished the GPS collection project for fire hydrants and have since GPS-ed storm drain crank inlets and about 20% of the water valves," says David Allen, GIS manager table for Euless. "Our storm drain maps were generated for a Governmental Accounting lift Standards Board statement drill but are useful press and crank and table to lift the fire department in containing chemical spills."Another drill benefit: Firefighters press no longer have to GPS-locate hydrants. "I typically go out and GPS the new ones as they are installed," Allen says. "Since this is only a few each month, it is easy for me to keep the maps current."
