Magnet-driven pumps set for Frankfurt
launch
Magnet-driven versions of Atex approved pumps are being introduced at Achema in Frankfurt, from 15th to 19th May.
Magnet-driven versions of Tuthill Pump Group's Atex approved Globalgear range are being introduced at Achema (hall nine, stand H27), Frankfurt, from 15th to 19th May The sealless magnetic-drive gear pumps are for applications involving hazardous fluids such as toxic liquids that tend to crystallise
They are available in sizes from GGMD015 to GGMD130 covering flow rates up to 492 litre/min and pressures up to 10barG.
The magnetic drive uses magnet-cooling technology and thrust control.
The pumps are for industries pumping viscous fluids, such as petrochemical, bitumen, asphalt, coatings, inks, paint, foam, plastics, resins and chemicals.
Features include: modular construction which gives flexibility for changing duties; 90- and 180-degree port configurations (imperial and metric); ease of maintenance; robust construction; low maintenance costs; multiple options for connections and flanges; and comparable performance with existing units.
Maintenance is facilitated by a back pull out feature that reduces downtime, frequently by as much as 60 to 70% compared with conventional alternative pumps.
Conventional shaft sealed Globagear pumps provide inline seal replacement and will accept gland packing, inboard or outboard mechanical seals, cartridges or double seals without modification.
All construction materials are equal or in many cases stronger than those of alternative units.
Cast iron and stainless steel versions are available and parts can be plasma nitride hardened using the Tutriding process for abrasive applications.
The pumps are also available with the company's TuffSeall seal option which can handle viscosities up to 160,000mPas, differential pressures up to 15barG and continuous temperatures up 190C (200C intermittent).
It can even handle intermittent dry-running situations.
TuffSeall is suitable for applications involving paints, coatings, resins, glues, polymers, greases and bitumen and asphalt.
TuffSeall has a silicon-carbide sleeve that is abrasion, grooving and fretting resistant plus proprietary metal-filled Teflon rotating sealing elements that have no springs to clog, no faces to stick together and no dynamic O rings to fail.
Other options include relief valves with a return to tank facility.
This is for applications where fluid needs to be relieved unworked, adding to the safety of operations.
Spares costs are reduced because parts are standardised across the Globalgear range.
This is illustrated by the fact that there are just three shaft sizes for the entire range (produced in imperial and metric) with a consequent reduction in inventory requirements for users.
Pumps come with NPT/BSP connections or flanges in Ansi or Din.
Additional flexibility of installation is provided by the facility to convert a flanged unit to a threaded one in minutes.
This means pumps can be readily adapted to suit different applications throughout a plant.
Previously plants would have needed to buy pumps to suit each application.
Performance of Globalgear pumps matches that of replaced units.
Consequently, users can simply connect the Globalgear pump to the existing drive to achieve the same performance.
