Overview of ATEX magnetically-coupled pumps
ATEX approved magnetically-coupled external gear pumps for precise dosing and metering are presented in a new full-colour, 6-page brochure from Tuthill Pumps
They are also easy to control via 4 to 20 mA feedback systems and are accurate to better than 1%.
By providing smooth flow, Tuthill external gear pumps avoid fluid agitation thereby eliminating the need for pulsation dampers.
The smooth flow also makes the external gear pumps flow meter and residual measurement friendly.
Vapour trapping is avoided as a result of the pump flow-through design.
The pumps have a long life expectancy 20,000 hours and, if there is a problem, with only two working parts they are easy to service in the field.
Additional durability is imparted by a robust 5 bearing design.
Handling capacities range from 1 ml/min to 38 l/min at pressures ranging to 17 Bar.
Flow control is speed regulated.
Most standard, variable-speed motors can be employed to drive the pumps.
The pumps are compact units engineered in 316L stainless steel, Hastelloy or Titanium.
