Vogelsang, the inventor of the rotary lobe pump with elastomer-coated lobes, showcased its advanced wastewater solutions at WEFTEC in New Orleans in early October.
This included the HiCone Progressive Cavity Pump, XRipper grinders, and the VX Rotary Lobe Pump.
The unique, patented design of the HiCone significantly extends the lifespan of wear parts, according to the firm — by several times compared to conventional progressive cavity pumps — while dramatically streamlining maintenance, increasing availability, and lowering power consumption.
In the firm’s explanation, the innovative adjustment system of the Vogelsang HiCone eliminates the need for frequent, costly, and difficult rotor and stator replacements caused by wear on the contact surfaces. Instead, operators can easily restore original pump performance with a simple turn of an adjustment nut using a standard wrench or through an automated system that can sense a drop in the pump’s output. This adjustment works due the cone-shaped rotor and stator design, hence the name HiCone. In the adjustment process, the rotor simply moves forward, reestablishing ideal compression without compromising the pump’s cavities or ability to operate safely. This HiCone adjustment system can be precisely calibrated to suit operating conditions, allowing it to maintain the specified performance while extending service life as much as 3-4 times as compared to typical PC pumps.
Attendees at WEFTEC were treated to a demonstration of the HiCone in action and Vogelsang’s broad range of solutions that address the diverse and demanding needs of municipal wastewater management.
The VX Rotary Lobe Pump, for instance, is engineered for precise control, offering pulsation-free, low-vibration and exceptionally gentle pumping.
Vogelsang also showcased their “one-two punch in solids reduction”. The XRipper grinder is claimed to excel at grinding and shredding tough solids in headworks channels to preventing pump clogs and damage to downstream equipment caused by wipes, rags and other debris. “The RotaCut macerator is in a class of its own when it comes to cutting up fibrous materials, hair, and other solids that make it past screening systems,” said the firm’s literature.
