Safe small-volume filling of aggressive media

Electric laboratory pumps have been proven for decades in a variety of industries and applications where aggressive media such as acids, alkalies or cleaning media are removed in small batches from cans or drums.

The pump manufacturer JESSBERGER has expanded its program with a PVDF laboratory pump. Small quantities of chlorine- and fluorine-containing media can be transferred easily, quickly and safely with this chemical drum pump. 

The demand for the production of this new laboratory pump came in particular from large customers from abroad and from customers in the areas of waste disposal, wastewater and drinking water treatment, the treatment of swimming pool water as well as the chemicals trade and the galvano industry.



The laboratory pump is made of highly resistant fluoroplastic PVDF (polyvinylidene fluoride) and a drive shaft made of Hastelloy C-2.4610. The materials have excellent chemical and thermal resistance.

The pump tube was designed without seal and without lubricant, so that on the one hand a dry running is possible and further contamination of the media to be pumped is excluded. The IP 24 splash-proof universal motor JP-140 convinces not only with its design and light weight, but also with its easy handling and low noise level.

In contrast to many other models available on the market, the  motor with low voltage release has an output of 450 watts and is therefore suitable for densities up to 1.3 and viscosities up to 400 mPas.

It was chosen a suction tube diameter of 32 mm, so that the emptying of all common small containers is possible and a good stability of the dip tube is given. Immersion depths of 500 and 700 mm (for canisters), 1000 mm (200 liters) and 1200 mm (IBC with 1000 liters) are available. Special lengths can be made within 1-3 days.

The laboratory pump was, like all previous drum pumps of this manufacturer, very service-friendly and can be combined with all other drives of the manufacturer. It is also possible to operate with air operated or special motors (24 volts or timely available motors in 12 volts or as a battery motor in 18 volts).

In particular, highly aggressive media such as sodium hypochlorite, chromic acid, hydrofluoric acid, sodium hypochlorite, nitric acid and other chemicals can be safely transferred with this pump. For highly concentrated sulfuric acid (density 1.8) a more powerful drive with 825 watts should be used. The pump delivers max. 49 l/min and builds up a discharge pressure up to 1 bar.
