Design and function of the pump system BioCut
How the pump system BioCut works

The BioCut is an efficient pump system for reliable and cost-effective pumping of heterogeneous media containing heavy material and disruptive matter. It consists of a self-priming rotary lobe pump from the VX series combined with a special type of construction of the tried-and-trusted wet grinder RotaCut – with both optimally coordinated and arranged to one another. The rotary lobe pump draws the medium – even out of a pit, if necessary – through the RotaCut. The RotaCut then separates out foreign matter (stones, metal parts etc.) due to their size or weight. During maintenance work, this foreign matter can then be removed through the cleaning port. Light solid matter and disruptive matter, such as fibers, wood etc., are drawn along in the flow of fluid to the cutting screen, where they are cutted and mixed with the fluid. This way, the pump system BioCut turns a heterogeneous fluid into a pumpable, homogeneous suspension. This suspension then reaches the rotary lobe pump on as short a route as possible.

Service and maintenance of the pump system BioCut
The pump system BioCut and the QuickService principle

When developing the BioCut pump system, we made sure to retain the full range of QuickService functions in the VX series rotary lobe pump and the RotaCut wet grinder: The RotaCut can be opened in a few simple steps, giving you free access to the cutting tools. Once the adjustment unit and the blade rotor have been dismounted, you can remove the cutting screen and, if necessary, renew the gasket. Replacing parts on the VX series rotary lobe pump is just as easy. When the cover is dismounted, you have free access to the pumping chamber and you can pull the rotary lobes off the shafts.

If necessary, you can also replace the axial wear plates, the pump housing segments and the Quality Cartridge mechanical seal.

The two components can both be maintained quickly on site, allowing the BioCut pump system to be put back into operation after a very short time. There is no need to dismount the pipe. This reduces downtime to a minimum.

Control technology for Vogelsang technology

Investing in our progressive and smart control technology significantly boosts the performance and efficiency of Vogelsang machines and systems. It captures and continuously monitors key parameters like the capacity or throughput rate, rpm, pressure and power consumption. The control detects malfunctions early, and rectifies them by intervening appropriately. The integrated communication interfaces like ProfiNet and OPC UA can exchange data with other systems or a superordinate control in real time.

At the same time, the web-based user interface displays all key data clearly in all major browsers. Optionally, the data can be accessed on mobile devices for remote monitoring.

Our experts’ experience from hundreds of applications in various areas constantly inspires our software development and lays the foundation for the major benefits for the users: low operating costs, maximum availability and efficiency.

Our range of controls offers the right solution for all machine requirements and all customers’ needs. From ready-to-use, factory-tested and commissioned system solutions for end users, to basic versions for experts who want to put the finishing touches to the control technology themselves.

Features of the BioCut

Separation of stones and metal parts is important for ensuring smooth operation of the cutter itself as well as of the downstream pumps and components, and also to prevent damage and blockages they may cause. Each RotaCut therefore has an integrated heavy material separator.
The pump and RotaCut are combined in the pump system in a way that ensures the QuickService functions are retained in full. The wear parts can be accessed in a few easy steps. They can be replaced quickly and easily on site. The pump system is ready for use again in no time at all.
On rotary lobe pumps from Vogelsang, wear on the pump housing segments is compensated without using additional parts. This makes the most of the material and prolongs service life.

Additional information:
VX pumps from Vogelsang have sturdy, break-proof shafts with a large diameter and without cranks and recesses to weaken them. The benefit is that Vogelsang rotary lobe pumps give a minimum shaft deflection even under high pressure, very low start-up wear, and ultimately reduced operating costs and spare parts costs.

Additional information:
Vogelsang rotary lobe pumps are built according to a unique element-based design. With them, the customer isn’t forced to replace the entire body, but instead just the element that is affected. The economical replacement of individual components not only makes maintenance simpler and quicker, but simultaneously reduces the operating costs.

Additional information:
Vogelsang uses its proprietary software to develop cutting screens with optimized geometry for every size-reduction ratio. For operators, this means the best geometry at all times for smooth running, with minimal wear. The cutting screens are produced from wear-resistant special steel and offer twice the performance since they are reversible.
Quality cartridge: The mechanical seal for pumps by Vogelsang
The Vogelsang Quality Cartridge stands for modern sealing technology. The mechanical seal in cartridge design is manufactured automatically in the factory, completely pre-assembled and checked by computer. This makes it quick and easy to change on site: assembly errors are avoided and the time required is reduced. This means quick and easy replacement of the shaft seal as well as safe commissioning after seal replacement.

More information
The pump and the cutter are mounted together and optimally arranged to one another. This result in short suction pipes, a flow which is directly pumped to the cutting screen and a very compact design. Therefore, the pumping systems required only a minimal footprint but are nevertheless easily accessible for maintenance and service.
The self-priming pump can prime media from depths as low as 9 meters.

Options of the BioCut

If it is necessary during priming to evacuate large quantities of air from empty pipes or if you need to prime a medium with a tendency to outgassing, the connector box is an ideal addition. It increases the suction capacity of the rotary lobe pumps in the VX series and ensures that even large volumes of air or gas are reliably evacuated or pumped.
InjectionSystem for rotary lobe pumps by Vogelsang
The InjectionSystem significantly improves the foreign-matter resistance of the pump. It increases the efficiency and improves the suction capacity through optimized volumetric efficiency. Thanks to the InjectionSystem the service life of the pump is extended. Field trials prove a longer period of up to 2.5 times.

Additional information:
The wear plates, made from highly wear-resistant special steel, extend maintenance intervals considerablx, simplify maintenance and minimize downtimes. Also your costs are significantly reduce during maintenance.

Additional information:
Unlike conventional lobes, Vogelsang’s HiFlo® lobes ensure pulsation-free pumping and consequently longer lifetimes for the drive and coupling. At the same time, the suction capacity is increased due to the higher number of sealing lines. The improved internal sealing enables suction from deep pits.

Additional information:
Along with the number of cuts, the hole pattern in the cutting screens is crucial to the size-reduction ratio. To be able to meet all requirements, we offer cutting screens for the RotaCut with a free passage of 4 mm to up to 50 mm, depending on the unit size. Stainless steel designs are available for aggressive media.
ACCplus further reduces the cost of maintenance and monitoring of the cutter. It monitors the cutting blades status online and displays it on an external display. This means it's no longer necessary to place the cutter out of service and open it to determine the cutting blades status. Additionally, this information can be processed and displayed by the (central) control and/or remote control.
The Auto-Reverse function detects blockages, such as those caused by coarse disruptive matter, and initiates corrective action. By periodically reversing, the function further ensures that a pair of sharp cutting edges is always used while dull ones are sharpened on the opposite site. This delivers optimal cutting performance with reduced power consumption.
