Netzsch pumps up the volume.


New generation beverage pump

Leading progressing cavity pump manufacturer Netzsch Pumps has introduced a new generation of Netzsch Beverage Pumps that guarantees a smooth and reliable conveyance of fluids such as mash, concentrates, fruit and vegetables juices, nectar, sugar solution, syrup, whole grapes, must, sludge, yeast and wine.

The robust and economical range can achieve differential pressures up to 6bar and flow rates can be varied using the integrated speed control in the drive. The flexible beverage pump range is available in four models--the small 0.75kW portable version achieves flow rates up to 5,0001/h, while three trolley-mounted mobile versions (2.2, 3.0 and 5.5kW) achieve rates from 1,500 to 32,000 l/h. A choice of three different rotor geometries is also available.

The service-friendly, modular design includes a food-quality stator approved to FDA and BVGG standards, with contact parts manufactured completely from CrNiMo steel.

Commenting for Netzsch Pumps, managing director James Harvey says: "The beverage pump is ideal for most beverage production applications and we believe there is a huge potential in the UK with its growing market for quality wines, specialist beers and soft drinks."

Dual-stator now fitted as standard

Following the launch of Netzsch's new dual-stator system last year, the company has announced that the iFD-Stator[R] is now fitted as standard to all NM Series pumps with a nominal rotor diameter between 21mm and 63mm.

The dual-stator system comprises of a stator and stator housing that the company claims differs from all existing stators by offering significant advantages in capacity, economy and environmental protection, with the system being endorsed by the Deutsche Bundesstiftung Umwelt (German Environmental Foundation).

The iFD-Stator, which is compatible with all NEMO[R] pumps from the NM series, prolongs stator lifetime and reduces lifecycle costs thanks to its manoeuvrability within the two-part reusable housing. The use of a separate housing and stator means that, when worn, only the stator needs to be replaced and is therefore more easily disposed of.


During assembly, the over-sized stator--which is manufactured using Netzsch's environmentally friendly NEMOLAST[R] $65 elastomer--easily slides over the rotor allowing for the optimum operating dimension to be achieved through axial constriction.

Its reduced initial breakaway torque allows for the selection of smaller pump drives, which means that investment costs and energy consumption are reduced. And, with the addition of an optional regulator, the iFD-Stator can be infinitely adjusted to process parameters such as temperature, working pressure and continuous wear compensation, which can also result in extended stator and rotor life.

The iFD-Stator is manufactured to tight production tolerances, is available with S and L geometries and capable of transferring media at rates from 0.5 to 50m3/h at pressures to 12 bar.

Commenting for Netzsch Pumps, environmental applications engineer Keren Booker says: "As well as being environmentally friendly in its manufacture, the iFD Stator is also service friendly, requires minimum maintenance and improves plant safety."
