FLUX Pumps for the Industry sector


Machine and mineral oils, hydraulic fluids, and industrial greases are the lubricants that keep the industrial engines running. Engine oils and white spirits also provide the necessary drive in the automotive industry. The diversity of the media being processed is just as broad as the range of viscosities.

FLUX is happy to provide you with personal advice, even on site, and demonstrate which filling concept should ideally be used for which application. At the same time, we will also show you the optimum solution to guarantee safe and reliable operation in potentially explosive atmospheres with explosion protection.

Application descriptions

Filling gearboxes with lubricant grease

In one division of a gearbox manufacturer, various gearboxes are to be filled with lubricant greases of classes 1 to 4 in quantities of 0.4 to 1.2 litres at room temperature. The grease is removed from 200-litre drums and the transfer path is up to 2 m. The grease drips in certain cases.

Customer's requirement:
- Filling accuracy:  +/- 10 g   
- Delivery pressure:  up to 4 bar  
- Flow rate: 20 l/min
- The transfer system must be able to fill for 2 hours per unit and do so several times a day.

Application description:
The VISCOFLUX lite drum-emptying system for pumping high-viscosity, media barely capable of flowing offers precisely the suitable solution in this case.

The drum-emptying system consists of an F 550 S eccentric worm-drive pump with a gear motor, a pump eccentric crossbeam and a follower plate. The plate is positioned on the lubricant grease and sealed air-tightly against the drum wall by the process seal. The pump eccentric crossbeam is placed on the drum. Then the eccentric worm-drive pump can be guided through the opening of the crossbeam and the guide of the follower plate down to the bottom of the drum. During pumping – i.e. removal – a negative pressure arises in this manner, with the result that the follower plate sinks.

The follower plate seals so flexibly that there is almost no medium residue left on the drum wall; ultimately there have been residual quantities of less than 1% in the drum. After emptying, the follower plate is released from the bottom of the drum by compressed air. At the end of the filling hose, there is a FLUX FAE filling unit, which prevents dripping of the medium thanks to a check valve.
