Vogelsang GmbH & Co. KG has launched HiCone progressive cavity (PC) pump, which combines a conical form with an innovative setting system to conserve energy and significantly extend its service life.

The HiCone supports pumping capacities of up to 290 m3/h, and its revolutionary, conical shaped rotor and stator, as well as its clever adjustment system, allows for high profitability and durability. Brad Adams, Managing Director at Vogelsang Pty Ltd said, “With the HiCone, we are once again setting new standards for progressive cavity pumps. We have met the demands of our customers for reduced life-cycle costs and longer service times with the further development of our technology.”

Re-adjust instead of changing parts

With conventional progressive cavity pumps, if a gap arises between rotor and stator due to wear in operation, the capacity drops. This often means a sudden, drastic fall of the pump performance and the replacement of the rotor and stator. Conversely, the HiCone allows axial readjustment of the rotor.

Its conical shape ensures that the gap is regulated, meaning that the pump is back to its original condition and the pumping capacity returns to 100 per cent. Instead of the costly and time-consuming process of changing parts, the problem can be solved with a quick and easy adjustment made during ongoing operation.

Combined with Vogelsang’s integrated QuickService concept, this significantly reduces life-cycle costs for the user and higher pump availability, since there are no elaborate service deployments.

A unique swivelling mechanism

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.

Lower electricity requirement for increased energy efficiency

Thanks to the clever adjustment system, the rotor and stator can be optimally positioned to each other according to operating parameters, such as pressure, temperature and viscosity. This results in lower power consumption, which reduces the electricity requirement. Wear is also reduced at the same time.

Automatic start-up delivering higher efficiency

In addition, the HiCone’s automatic start-up saves power. The rotor and stator are positioned in such a way that there is only minimal clamping between them. This means that a smaller motor is needed to ramp up the pump than in conventional progressive cavity pumps, which reduces the power requirement when starting the pump to a minimum.

This increases the energy efficiency and reduces the costs for power electronics. The result is lower electricity costs and reduced procurement expenses for users. The start-up process is fully automatic without the need for additional control. The clamping between the rotor and stator can be adjusted during the entire service life at the touch of a button or at the click of a mouse from the control room.

Online monitoring of the status

Mr Adams said that 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 receive continuous information and can plan parts changes in advance,” Mr Adams said. “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 re- adjusted.”
