VX series – the rotary lobe pump for liquid manure technology

Vogelsang rotary lobe pumps in the VX series are the ideal partner for liquid manure technology. On the one hand this liquid manure pump offers every tanker size maximum capacity thanks to its high efficiency. On the other hand, they are independent of the direction of rotation. This saves on pipes to tankers. But this also enables more efficient use of the payload on the tanker, self-propelled vehicle or liquid manure transporter. Thanks to their compact dimensions, the VX series pumps are ideal for mobile applications and are up to 37% lighter than comparable models. Added to this, with its wealth of technical innovations, the VX series is designed to increase operational safety in the tank and to lengthen the service life. For example, the HiFlo lobes guarantee low pulsation pumping compared to conventional lobes. This enables higher limiting speeds and greater delivery rates. This is especially useful for applications on tankers. The patented InjectionSystem stops the lobe tips from being damaged by foreign matter such as hoof blocks, as the innovative housing shape allows the optimum flow of foreign matter through the rotary lobe pump. Its excellent maintainability makes it possible to change all components without dismounting the rotary lobe pump. This makes it possible to keep standstill to a minimum during the liquid manure season, for example. All these characteristics show that the VX series is the ideal solution for a liquid manure pump.

Biogas

VX series – the all-rounder pump for biogas plants

The rotary lobe pumps in the VX series are the ideal solution for many pumping tasks in biogas plants. They reliably convey liquid manure, greases, flotation tailing and other liquid media – directly to the digester, the mashing tank or the liquid feeding system, or to digestate dehydration. The patented HiFlo® lobes enable pulsation-free and low-vibration pumping.
In many biogas plants, rotary lobe pumps from the VX series act as the central pump. They prime liquid manure out of pits, evacuating air from empty pipes in the process. Even if the liquid manure contains foreign matter such as stones and screws: thanks to the InjectionSystem and the large free passage, Vogelsang rotary lobe pumps are resistant to foreign matter. Even organic suspensions, recirculate or low-viscosity digestate can be pumped without difficulty, e.g. from the digester to the post digester and vice versa: By changing the direction of rotation of the drive, it is easy to reverse the flow direction. This characteristic is also an advantage for tankers, as only one pump is needed for both filling and draining. The VX series stands out here thanks to its small space requirements: The pumps can generally be installed easily on a vehicle or in the space between the digester and post digester.
Thanks to the QuickService concept, they can be serviced or repaired quickly and simply on site. All wear parts can be changed without dismounting and with limited space requirements, in order to restore 100% of the capacity.

Wastewater

VX series – the all-rounder pump for waste water and sludges

The rotary lobe pumps in the VX series pump sludge efficiently in waste water treatment; from primary sludge, through excess and secondary sludge, to concentrated digested sludge or sewage sludge. But the VX series rotary lobe pumps are also suitable for waste water loaded with foreign matter. The large free passage and the InjectionSystem make them resistant to foreign matter. The ability of the rotary lobe pumps to also prime from pits and to evacuate air from empty waste water pipes make the VX series pumps ideal for waste water. The symmetrical design makes it possible to operate the pumps in both directions, e.g. to extract from disposal vehicles and also to fill tankers using the same pump. The HiFlo® lobes provide pulsation-free, low-vibration pumping of waste water and sludges. The combination of high output and minimal space requirements make the rotary lobe pumps in the VX series the ideal solution for mobile pump units. Thanks to other special features and options, they have long service lives, whether used in a sewage treatment plant or the sewers. When maintenance or service work is necessary, the pumps can be maintained or repaired quickly and easily by in-house staff at the sewage treatment plant or the pumping station, thanks to the QuickService concept. On request, our service mechanics can perform all the necessary service and maintenance work. The shafts are sealed as standard using a mechanical seal, but a block ring seal is also available – and it can conform to air quality control guidelines (TA-Luft) if necessary.

Features

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:

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.

Additional information:

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, SBR, 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 or 4-wing, pulsation-free HiFlo lobes.

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.

The Quality Cartridge mechanical seal is checked in the factory and when it is changed, all of the seal components are also replaced. This protects against sudden failures of the seal and potentially fatal damage. The complete unit is easy to change, and the replacement process takes significantly less time.

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.

Options

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:

Radial wear plates are only available in Vogelsang rotary lobe pumps. 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:

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.

The Universal Drive System (UDS) allows the same VX rotary lobe pump to be operated with a number of different types of drive (hydraulic and geared motors, classic cardan shaft, three-speed gearbox) or locations (stationary, mobile). This is done by combining the pump with a shaft and drive adapter. The UDS makes spare parts management easier and enhances flexibility.

An ATEX-compliant version can be supplied for use in areas subject to explosion hazards.

In the QD design, an additional, third support bearing provides extra stability and extremely low shaft deflection, resulting in minimal pressure-related wear. The marathon pump is a QuickService pump in a two-stage design with a third bearing in the cover works with half the pressure differential, which results in a longer lifetime.

Vogelsang’s rotary lobe pumps themselves are also compact in design, which saves weight. Also thanks to the pumping technique a considerable reduction in pipes is possible. Therefore Vogelsang rotary lobe pumps weigh up to 37 % less that comaprable models on the market.

Additional information:

We offer another option which is perfectly suited to road transport: aluminum pump housing and lobe cores. This helps haulers to keep the tare of the transport vehicle to a minimum and thus increase the payload. The gearbox housing, bearing seal housing and QuickService cover are all made of aluminum. Particular attention has been paid to making sure that all components that come into contact with the medium are lined with robust gray cast iron or highly wear-resistant special steel.

The rotary lobe pump is a positive displacement pump. The pumping principle behind rotary lobe pumps is based on two counter-rotating pumping elements, known as the rotary lobes. These are mounted on two overhung shafts synchronized by means of synchronized gearing. The bearings for the shafts are also arranged in the gearbox housing. 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.

VX series - the rotary lobe pumps by Vogelsang — **VX series on a trailer**

We use a variety of simple options to make the VX series mobile. This way, a pump can perform its pumping tasks at various locations, and transporting the pump from one place to the next couldn’t be easier.

To supply extinguishing water, for example, the VX series can be placed on a trailer and operated by a combustion motor in that position. Fire departments are then ideally equipped for emergencies such as firefighting or flooding. Long suction lines over rough terrain and hard-to-access deployment sites are then no longer a problem. The VX series is resistant to dry running and can also prime extinguishing water across long distances.
