Vogelsang VX Series Rotary Lobe Pumps


The rotary lobe pumps in the VX series pump sludge efficiently in wastewater treatment; from primary sludge, through excess and secondary sludge, to concentrated digested sludge or sewage sludge. But the VX series rotary lobe pumps are also suitable for wastewater loaded with foreign matter. The large free passage and the Injection System make them resistant to foreign matter. The ability of the rotary lobe pumps to also prime from pits and to evacuate air from empty wastewater pipes make the VX series pumps ideal for wastewater.

The symmetrical design makes it possible to operate the pumps in both directions, e.g. to extract from disposal vehicles and also to fill tankers using the same pump. The HiFlo® lobes provide pulsation-free, low-vibration pumping of wastewater and sludges. The combination of high output and minimal space requirements make the rotary lobe pumps in the VX series the ideal solution for mobile pump units. Thanks to other special features and options, they have long service lives, whether used in a sewage treatment plant or the sewers. When maintenance or service work is necessary, the pumps can be maintained or repaired quickly and easily by in-house staff at the sewage treatment plant or the pumping station, thanks to the QuickService concept. On request, our service mechanics can perform all the necessary service and maintenance work. The shafts are sealed as standard using a mechanical seal, but a block ring seal is also available – and it can conform to air quality control guidelines (TA-Luft) if necessary.
