Encasing a metal core with a rubber covering - that was not only the simplest but also Helmut Vogelsang's cleverest idea. It makes the rotary lobe pump insensitive to foreign matter and provided a myriad of possible market applications. We are working closely with experienced, specialised companies for manufacturing these lobes. Therefore these expert companies guarantee a high quality. The rubber casing is connected to the metal core using a vulcanisation process, fully covering the lobes with rubber.
The following materials are available as an
elastomeric / lobe material:
NBR
HNBR
SBR
EPDM
Viton
Werobust
CSM
AFLAS
as well as
steel
stainless steel
POM
The HiFlo lobes
For a long time, pulsation severely limited the capability of rotary lobe pumps. By developing the HiFlo lobes, whose tips are wound about the axis at a defined angle, the Vogelsang engineers succeeded for the first time in reaching the pulsation breakthrough. With the knowledge of generating the right geometry and through the development of a vulcanisation process to produce a seamless "all around rubber casing", a new age dawned. Because of this innovative development, pulsation-free operating rotary lobes with a selectable number of tips are now available.

The HiFlo lobes provide an array of possible industrial applications for rotary lobe pumps. Today the HiFlo lobes are standard in all Vogelsang rotary lobe pumps.
This makes the HiFlo lobes unique:
Pulsation-free operation
means a longer lifespan, reduced maintenance costs and quieter operation.
---------------------------------------------------------------- ----------------
Higher pumping capacities due to higher speeds.
------------------------------------------------------------------- -------------
Improved suction characteristics
through reduced cavitation.
--------------------------------------------------------------- -----------------
Self-priming up to 8 m.
------------------------------------------------------------------------ --------
Higher operational pressures by eliminating the pressure spikes caused by pulsation.
