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 hand drill press to standard centrifugal pumps, adds press smith. reviews 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 drill to smith. pump improvements have been accelerated with the application of 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 press 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.

models 420d and 430d backhoe loaders, and 420d it and 430d it integrated toolcarrier (it) configurations, offer new single-lever, pilot-operated, excavator-style joystick controls for smooth, hydraulic loader functions. new models feature cat 3054t turbocharged, direct-injection. 4-cylinder engines with 4.0 liters displacement, fuel-injection, and power-shuttle transmission with on-the-go shitting and synchromesh in 4 forward and 4 reverse gears. auto-shift option with manual override automatically shifts between second gear and highest selected gear in 5 forward and 3 reverse speeds. also have standard 2-wheel reviews or on-the-go, all-wheel drive with oil-immersed hydraulic, multiple disc brakes. 420d has 85 net hp. and backhoe digging depth of 14 ft. 5 in. with standard stick; extendible stick pushes depth to 18 it. 1 in. 430d has 94 net hp. and digging depth of 15 ft. 3 in., extendible to 19 ft. l i in. variable-flow, closed-center, load-sensing hydraulic system adjusts flow and pressure to 3,300 p.s.i. for full hydraulic force to work tools at any engine speed. single-pin backhoe bucket has 205[degrees] linkage rotation with integrated lifting eye. operator station includes white-faced gauges, hand throttle, new boom lock position, and pilot-operated stabilizer controls. a portable backhoe that can be towed to a job site, unhooked, and then used has been introduced. heavy enough for commercial use, the backhoe is ideal for use by farmers, plumbing contractors, homebuilders, landscape contractors, and large-scale gardeners.
