Mag-drive option for critical
applications
At ACHEMA, Tuthill Pumps will introduce seal-less magnet-driven versions of the ATEX approved GlobalGear range of pumps, for use where process/product integrity is a critical requirement
The new Tuthill GlobalGear seal-less magnetic-drive gear pumps are designed to extend the range of options the company can offer, particularly for applications where product/process integrity is a critical requirement They are ideal for applications involving hazardous fluids such as toxic liquids that tend to crystallise

A new magnetic-drive vane pump with all non-metallic wetted surfaces for chemical and temperature resistance is to be introduced at ACHEMA, Frankfurt, by Tuthill Pumps
They are available in models from GGMD015 to GGMD130 covering flow rates up to 492 litres/min and pressures up to 10 BarG.
The Tuthill magnetic drive system employs patented magnet-cooling technology and thrust control.
Tuthill GlobalGear pumps are ideal for industries pumping viscous fluids, such as petrochemical, bitumen/asphalt, coatings, inks, paint, foam, plastics, resins and chemicals.

Principal features of the Tuthill GlobalGear pumps are: 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/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 GlobalGear Pumps, offer in-line 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 significantly stronger than those of alternative units.
(See note on "TuffSeall" below).
Cast Iron and Stainless Steel versions are available and parts can be plasma nitride hardened using the 'Tutriding' process for abrasive applications.
GlobalGear pumps are also offered with the company's 'TuffSeall' seal option which is designed to handle viscosities up to 160,000 cps, differential pressures up to 15 BarG and continuous temperatures up to 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/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' un-worked, adding to the safety of operations.
Spares costs are minimised 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 both 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, simply connect the GlobalGear pump to the existing drive to achieve the same performance.
ACHEMA is from 15-19 May in Frankfurt, and the Tuthill Stand can be foiund in Hall 9, on Stand H27.
