Vogelsang GmbH & Co. KG has launched a new progressive cavity pump for use in biogas plants. The conical form, combined with an innovative setting system, saves energy and significantly extends the service life. The HiCone supports pumping capacities of up to 290 m3/h.To get more news about progressive cavity pump spare parts, you can visit brysonpump.com official website.

If a gap arises between rotor and stator due to wear in operation, the capacity drops. Whereas with conventional progressing cavity pumps, this often means a sudden drastic fall of the pump performance and the replacement of the rotor and stator, the HiCone solves this with axial readjustment of the rotor. The conical shape ensures the gap is regulated, as a result of which the pump is back to its original condition and the pumping capacity returns to 100 percent. Instead of the costly and time-consuming changing of parts, there is a quick and easy adjustment – during ongoing operation.

Combined with Vogelsang’s integrated QuickService concept, this means significantly reduced life-cycle costs for the user and higher pump availability, since there are no elaborate service deployments. If replacement is nevertheless necessary, the rotor-stator unit is swung out and can then be renewed either as a unit or individually. A wear-resistant sleeve, which does not need to be unmounted to change parts, protects the sturdy cardan shaft.
Since then the 20 multiphase pumps have been providing their service for more than six years in the Melut Basin. At the end of 2011, the developers asked the operators about their experiences so far and checked the condition of the equipment, which had been running without any significant problems up to that point. Above all the pivot joints proved themselves over sustained use: since then no maintenance work has been needed either on the joints, the drive chain or the bearing housing. Wear had only occurred on the stators and mechanical seals of some pumps, which had to transport extremely large quantities of sand in the pumped material, meaning that these components had to be replaced. On the other hand, many of the pumps which were not used in such particular load phases are still running with the original stator, in spite of the hard working environment and the difficult conveyance conditions.
