Video of the DESMI in-line DSL double suction centrifugal pump. The design of the suction side provides for a perfect flow, and the inlet is placed in line with the outlet. Add to this the advanced double suction impeller and the result is high efficiency and low NPSH-values.
Alemite announces the introduction of its new Model 6800 Lever-Action Coupler to make lubrication quicker and easier.
This coupler is ideal for lubricating agricultural, construction, industrial, trucking, automotive and commercial lawn equipment – anywhere a grease gun is operated. The Lever-Action Coupler provides easy attachment and removal from the fitting. Its excellent sealing minimizes grease waste to lower lubricant costs. Featuring an ergonomic lever design, the coupler remains attached to the fitting without being heldin place, enabling one-handed grease gun operation. Its sturdy, all-steel construction with spring-steel jaws delivers maximum durability.
The coupler’s nylon sleeve offsets pressure applied at the lever and protects the hose from unnecessary wear.
Suitable for operating with manual, pneumatic and cordless grease guns, the Lever-Action Coupler provides simple release and is designed to save the user time.
Established in 1918, Alemite is a leading worldwide provider of lubrication and fluid handling systems and equipment. Products include oil mist systems, fluid management controls, pumps, reels, meters, fittings and grease guns.
NOV recently launched the Tolteq™ iSeries near-bit sub (iNBS), which is a near-bit tool that provides real-time inclination and azimuthal gamma data for geosteering applications. The dynamic inclination measurement from the iNBS tool allows for continuous monitoring of well-trajectory progression while drilling.
The iNBS tool connects with our Tolteq iSeries mud pulse measurement-while-drilling (MWD) platform enabling real-time data transmission. Accurate well placement can be achieved, even in the thinnest of reservoirs, because the iNBS tool provides continuous inclination and azimuthal gamma images with up to eight sectors available in real time.
As one of the shortest near-bit measurement sub on the market, the iNBS tool retains effective steerability when it is run below a motor.
Transferring extremely aggressive chemicals presents tough challenges for pumps, where despite the risks, a safe, reliable and accurate pumping performance is essential. A good example of where such a pumping performance has been achieved is with Liquiflo magnetically coupled gear pumps supplied by Michael Smith Engineers. The application is at a leading UK manufacturer of industrial chemicals including surfactants and personal care products. The pumps were installed in 1996 and are still in service today, more than 20 years later.
The requirement was for 3 pumps to batch transfer a range of acidic and chloride based chemicals on a daily basis, operating up to 5 days a week. The nature of the application means that transfer rates are variable but in the region of 700 kg/hr at around 3.5 bar differential pressure. Due to the extremely aggressive nature of the chemicals being handled, the pumps selected were manufactured in Hastelloy C276. Also, because of the low viscosity of the product a Hastelloy drive gear with Ryton idler was specified to eliminate galling of the gears through lack of lubrication. The shafts were also Hastelloy running in Teflon bushings.
