Vogelsang‘s new progressive cavity pump for the biogas market

Developed to save energy during its use and significantly extend its service life, the HiCone pump features a conical form combined with an innovative setting not used before.To get more news about progressive cavity pump rotor, you can visit brysonpump.com official website.

“With the HiCone, we are once again setting standards for progressive cavity pumps,” said Jonathan Gutteridge, managing director for Vogelsang UK. “We have met the demands of our customers for reduced life-costs and longer service times with the further development of our technology. We are pleased to be launching it at this year’s World Biogas Expo and expect a lot of interest.”

The main benefits of the HiCone are a lower electricity requirement and an automatic start-up, and its ability to readjust reducing the need for replacement parts.

“Another advantage for users is that they can view the status of the pumping elements in a real-time display. Instead of being surprised by a sudden failure, they can receive continuous information and plan for parts in advance,” added Gutteridge.

“Our customers need technology that is long-lasting and can be flexibly adapted to differing pumping tasks and operating parameters. The HiCone gives them a highly efficient pump, which can be individually adjusted and readjusted.”

Dual-Stage Pumps
For a long time, centrifugal grinder pump manufacturers were offering the standard single-stage grinder in pressure sewer applications. These pumps could make do in some applications and could offer more flow than a progressive cavity grinder (55-60 gpm vs 15 gpm, respectively) but were limited to about 100 feet head (vs 150 feet). The benefit of a centrifugal pump was the characteristic of running along a pump curve. The pump can safely operate by idling at shut-off head without causing any damage. Unlike the progressive cavity pump, the centrifugal pump will simply wait for the system pressure to stabilize and will return to pumping as normal.

Due to these benefits, the single-stage centrifugal grinder pump was accepted as a good alternate in the market compared to the progressive cavity grinder pumps in lower head applications; however, that left a gap in the higher head applications. To address the market need for a higher head centrifugal grinder, dual-stage, centrifugal grinder pumps were developed specifically for pressure sewer applications. By sacrificing some flow, the addition of a second-stage impeller allowed double the head pressure. The result of this innovation was a centrifugal grinder pump that can operate at 200 feet head pressure and that, in low pressure situations, can pump nearly 30 gpm. Because of their higher flows, one centrifugal grinder pump operating under normal conditions can scour a two-inch line, opposed to progressive cavity grinder units, which require two to three pumps running at the same time to scour a 2-inch line. Keeping lines scoured is important for minimizing odor and preventing blockages. The cost to operate a dual-stage centrifugal grinder is often less expensive due to the shorter run times required because of higher flow.
