Here's the new 891 Series power takeoff (PTO), which is designed to help make PTO and pump installation simpler and more reliable on oil field exploration and maintenance trucks.
Because of the large physical size of the pumps used on these applications clearance has always been a challenge, the firm notes. The 891 Series was designed with this in mind to provide maximum clearance for the 4000-4500 Series transmissions with the oil cooler option. Another challenge, the company points out, is the torsional vibrations from today's diesel engines that prematurely wear out mating PTO and pump splines. The wet spline system that lubricates the mating PTO and pump shafts will increase the life of these components seven to 10 times longer than a dry mating connection, the firm says.
The 891 features six speed ratios, seven output types, and six shift options.

New trap reduces hydrocarbon to trace levelsThe new Systech hydrocarbon trap helps reduce hydrocarbon to trace levels for mass spectroscopy applications.
LC/MS (MS) or TOF/MS instrumentation has become extremely sensitive with increased resolution and processing speed, the company says. Thus it is imperative to remove background hydrocarbons for these very low trace determinations <15 ppb, it adds. The hydrocarbon-trapping device is based on activated carbon and with minimum pressure loss. The new sensitivity helps improve signal-to-noise and is suited for all MS applications. This accessory is designed to be connected between a nitrogen gas generator and the LC/MS (MS) to TOF/MS. A choice of 20 l./min and 40 l./min flow rates can accommodate high gas flow rates. The 1⁄4 in. and 6 mm fittings are included for use with most MS systems. The trap offers 300 psi pressure limit (2.07 MPa) and 572° F. (300° C.) temperature limit.
