Gear pump boasts pulse-free linear flow
Pulsafeeder's new magnetically driven rotary gear pump has been developed specifically for low-flow moderate-pressure applications.
AxFlow has launched Pulsafeeder's new magnetically driven rotary gear pump that has been developed specifically for the low-flow moderate-pressure applications where diaphragm, piston, progressive cavity, lobe, peristaltic, AOD and reciprocating plunger pumps have traditionally dominated Using nonmetallic materials for all wetted components, the all-new Eclipse pump displaces a constant volume of liquid per revolution and delivers a pulse-free linear flow that so many metering applications demand

The Blacoh Sentry protects pipes, valves, fittings, meters and inline instrumentation from destructive pulsations, vibrations, surges, cavitation, thermal expansion and water hammer.
Self-cleaning filter takes care of chips
A new development in self-cleaning disc filter technology is opening up opportunities for removing the harmful metal chips and fines from the coolant in machining centres.
All well and good, you might say; but where's the incentive to change from the tried and tested pump types that already come close to the holy grail of metering and dosing?.
The answer is very simple: Pulsafeeder has designed a pump that is made up from a miserly 16 components and is wholly leak-free because its magnetic coupling eliminates the need for mechanical seals.
With so few components, inventory control and spare parts holding is minimised and servicing can be performed in-situ within minutes.

Canned motor pump handles aggressive fluids
Developed by Wernert Pumpen for chemical duties, the Taifun 32-200 is a corrosion resistant, ATEX certified pump offering double hermetic sealing.
There are four models in the Eclipse Series, providing flows from 0.38 to 75.8 litre/min and accommodating pressures up to 13.8bar.
Should circumstances arise, the Eclipse is capable of dry running for up to 30min, a capability not matched by many other types of pump.
In terms of corrosion resistance, the use of fluoropolymers for components that come into contact with the pumped liquid allow the Eclipse to be employed for handling a wide range of chemicals and aggressive fluids.
In designing the Eclipse, Pulsafeeder has paid considerable attention to operating efficiency, minimum downtime and space availability.
Efficiency is represented by the pump's ability to handle low flow duties without the problems of cavitation, increased loads and unstable flow associated with centrifugal pumps.
Downtime is minimised because all wearing parts can be easily replaced by removing the front cover, whilst there also no need to disconnect piping or motor connections.
And because it is a compact design, the Eclipse has a far smaller footprint area, making it ideal for those duties where space and weight have to be taken into account.
"The arrival of the Eclipse is a very exciting development, for it offers a highly effective and competitive alternative to the traditional pumping technologies for metering and dosing", comments AxFlow Managing Director Tony Peters.
"The markets and range of applications for which the Eclipse can be specified are considerable, particularly where hazardous materials and environments are involved".
