 Pump it up"Centrifugal pumps have become more robust, with much tighter tolerances and stress analyses of components to increase efficiency and machine time to failure," according to Bruce Smith, North American sales manager for Fristam Pumps Inc., Middleton, Wis. Shaft deflection that results in moving parts hitting stationary components in the pump is a major contributor to pump failure, and manufacturers are addressing that concern.Liquid ring pumps are coming into play in the industry as an alternative to standard centrifugal pumps, adds Smith. Although these scavenger pumps have been around for a quarter of a century, pharmaceutical manufacturers have embraced the technology and forced redesigns that have expanded their applications. Liquid ring pumps are particularly adept at handling fluids with entrained air, an issue with cream, which tends to foam during transit. Liquid ring pumps do a superior job in fully evacuating a tank, a material-savings advantage that appeals to ice cream manufacturers and liquid egg processors, according to Smith. Pump improvements have mccullochchainsawpartsdealer been accelerated with the application of mccullochchainsawpartsdealer computational fluid dynamics (CFD) software, points out Russell Jones, business development manager-pumps for Alfa Laval in Pleasant Prairie, Wis. "From an R&D point of view, CFD is a big advance in optimizing design and increasing pump efficiency," he says. The technology has been instrumental in boosting pump efficiencies from the 40 percent range to 60 to 70 percent in recent years. A good friend called to let me know that there was an error in my thinking concerning aerial work platforms. I said "there is an aerial mccullochchainsawpartsdealer work platform in the field population in North America for every 1200 people, give or take a few." I should have said there''s an aerial work platform in the field population for every 950 people. That will decline this year to one machine for every 850 people, give or take a few. That''s still a lot of work platforms, no matter how you cut it! The 951 backhoe attachment from Great Bend Manufacturing mounts on skid steers from 40 to 100 hp and 55 to 100 hp tractors with Cat. II 3 point and I hitch. The 951 offers 9.7 ft. of digging depth with 4575 lb. of digging force. A tapered console and walk-through deck provide comfort and visibility to the operator and two double-action hydraulic cylinders replace chain links to ensure smooth swing operation, the company said. Attach hydraulic Ho-Pac Model 500 vibratory compactor/driver to mini-excavator, backhoe, or trencher to compact or drive soil in narrow trenches. Base plate measures 12 ins. wide and 27 ins. long. Boasts impulse force of 3,940 lbs. at 2,000 cycles mccullochchainsawpartsdealer per min. with minimum of 9 to 18 g.p.m. from carrier. Optional swivel-top mounting bracket permits precise positioning without moving carrier. My 22-month-old son is mad for trucks. And not just any trucks -- construction vehicles. Out of the vast variety of images he''s exposed to daily, he has honed in on dump trucks and cranes. How did this happen? My partner, Laura, and I are still trying to figure it out. Neither of us drives a big rig. Riley doesn''t watch TV. He has dolls. He loves flowers and animals. But boy, does he love backhoes. Looking for a chainsaw for sale?
