The rotary lobe pump principle
How Vogelsang rotary lobe pumps work

The rotary lobe pump is a positive displacement pump. The pumping principle is based on two counter-rotating pumping elements, known as the rotary lobes. These are mounted on two synchronized shafts. The rotational movement of the lobes increases the volume of the pumping chamber on the suction side. This creates suction, which draws the medium into the rotary lobe pump. As the rotational movement continues, the medium is then enclosed in cavities between the rotary lobes and pump housing and it is issued on the discharge side by the pumping chambers as they reduce in size again; the rotary lobe pump conveys the medium directly. Due to their mirror-symmetrical design, rotary lobe pumps are independent of the direction of rotation and can pump in either direction without restriction. The HiFlo lobes developed in the 1990s operate pulsation-free, ensuring low-vibration and exceptionally gentle pumping.

The all-round pump with high efficiency
Applications for VY rotary lobe pumps

The VY rotary lobe pumps are based on Vogelsang’s proven VX series. Different seals can also be variably used in the new housing – depending on industry-specific standards and requirements. This makes the VY series an all-rounder for use in, for example, the chemical industry as well as in the paper and textile sectors. The performance spectrum of the VY pumps ranges from 1 m³/h to 120 m³/h at a maximum pressure of 10 bar. Integrated sensors provide all the important information about the pump’s operating status. For media with abrasive components, the VY series is available with axial and radial wear protection.

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 VY series

The one-piece housing is low in dead space and flow-optimized, which increases efficiency. The service friendliness is further increased by the optimized connections.
The low dead space design of the one-piece housings allows for easy cleaning. The pumps can be flushed and disinfected according to CIP and SIP guidelines.
Alongside the standard model in abrasion-resistant gray cast iron, versions in ADI and stainless steel are stocked as well. On request, the components of the pump chamber can be manufactured from duplex steel or a nickel-based alloy. Other options for customization include heat treatment and wear-resistant coatings for the wear plates and housing components.
With our extensive selection of lobe geometry and materials, we will find the right long-life lobe for your media, e.g. NBR, NBR white, EPDM-SL, EPDM-AL, EPDM white, CSM, FKM, PU, stainless steel oder nitrided steel. The lobes can be produced in a straight, double-wing geometry or as 3-wing; 4-wing or 6-wing, pulsation-free HiFlo lobes.

Additional information:
Axial wear plates are made from highly wear-resistant special steel and therefore extend maintenance intervalls. They offer protection for the entire pump chamber and therefore not only simplify maintenance, but also minimize downtime. At the same time costs are minimized.

Seal supply systems have the task of keeping the lubricant of a seal at a constant level and maintaining the sealing pressure within the seal.
With its Automatic Supply Unit (ASU), Vogelsang has opened up a completely new world of seal supply systems.
The patented system is barely larger than a beverage can and consists of a reciprocating pump that interacts with the seal to pump sealing medium into the chamber as soon as the set pressure deviates.
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:
An ATEX-compliant version can be supplied for use in areas subject to explosion hazards.
The speed-dependent displacement of the VX rotary lobe pumps makes them ideal for precise longitudinal distribution within the spreading swath. Either screwed directly into the gearbox or in conjunction with the UDS both versions of the Vogelsang speed sensor are used to calculate the flow rate, allowing precise control of the required spreading capacity.
For sealing technology you can decide between the Quality-Cartridge, the new CoX-Cartridge and (for the EP series only) the API-Cartridge.
