Engineered solutions for highly viscous and abrasive media

Robust and powerful industrial pumps and macerators

The filling, draining and cleaning of stationary tanks and tank vehicles requires high throughput, as well as toughness and precision. The fact that Vogelsang rotary lobe pumps are also resistant to dry running is especially useful for complete pumping of a tank's contents. If this were not done, solid matter would collect at the bottom of the tank, gradually restricting its storage capacity. Due to the arrangement and thread of the lobes in industrial pumps from Vogelsang, the liquid is pumped evenly and without pulsation, independently of its viscosity. The design also ensures a high suction force. Using the innovative InjectionSystem, foreign matter (e.g. in waste oil) is also pumped collision-free, without damaging the lobes.

Vogelsang industrial pumps are equally suitable for the pumping of heating oil, vegetable oil, diesel or biodiesel in industrial ports or oil depots, as well as for pumping processes in tanker trucks or ships. The pumping direction of the highly efficient pumps is reversible, the compact design, especially of the IQ series, saves space and enables quick, cost-efficient on-site maintenance without the need for dismantling. A wide range of different lobes also allows the use of Vogelsang products for pumping substances such as heavy fuel oil, kerosene, petroleum or methanol in refineries. Even in membrane bioreactor technology for the reuse of process water in refineries, rotary lobe pumps are installed because the option to reverse the flow direction facilitates control of the backflow and pumping processes.

On the water and when fighting oil spills, time and safety are absolutely crucial for the successful prevention of environmental and human catastrophes. Their light weight and low space requirements along with their high pumping capacity make Vogelsang pumps highly valued for the construction of skimmers and side collectors. The combination of the unique rotary lobes and the housing design result in a smooth pumping action that prevents the emulsification of oil-polluted water. The self-priming pump technology overcomes height differences of up to eight metres, and is designed for pressures up to 16 bar. Mounted on a base or on a trolley, it thereby provides a highly efficient, mobile solution for the skimming of oil from the water surface.

The hydraulic drive on the compact pumps also enables underwater intake and expulsion of the environmentally harmful medium, including possible foreign matter. Even solid matter of up to 90 mm does not interfere with the reliable pumping process. Depending on their configuration, these tried and tested, dry running resistant machines can even pump bitumen. They can do this in both directions, which is why they are often used to empty oil tanks and as feeder technology for centrifuges.

For a trouble-free, maintenance-friendly and cost-effective pumping process in demanding industries such as the chemical industry, performance is as important as flexibility. Mortars, paints, adhesives, soaps, lyes or acids all have their special features and are subject to very strict safety requirements. Non-contact rotating positive displacement pumps as employed by Vogelsang are specifically preferred for the pumping of highly viscous, aggressive and abrasive media, as they can move a variety of fluids safely, quickly, without pulsation.

Vogelsang pump technology has proved itself in this area due to the particularly compact design of its industry pumps and their simple maintenance requirements. The space-saving design allows for installation in a confined space, enabling use in different procedures including with different dosages. For this reason, Vogelsang provides different pump types made of different materials. Also pump chambers and lobes of different shapes are designed for a specific application. No matter whether steel, stainless steel or nickel alloy, our closed-chamber pumping system with its exceptional suction and dry running performance, ensures maximum efficiency.

Vogelsang industrial pumps can pump flowing media with viscosities of up to 100,000 mPas, including:

• Mortars and plaster coatings
• Paints and varnishes
• Rubber solutions, glues and adhesives
• Bitumen
• Natural latex
• Pesticides and chemical fertilisers
• Soaps, shampoos, creams and pastes
• Cosmetic raw materials
• Acids, such as sulfuric acid, nitric acid, formic acid and acetic acid
• Bases such as sodium lye, potassium hydroxide lye
• Chlorine, dry chlorine or chloride media
• Ceramic and other emulsions
• Polymers
• Hydrocarbons
• Hydrogen peroxide, oils such as fuel oils, solvents or esters
• Salt solutions, such as sodium sulfate
• Kaolin or lime milk
• Waste water from the chemical industry

Blood, guts, bones, heads and hooves – the meat industry generates large quantities of this waste, some of which is critical to the food industry and must be disposed of professionally. In addition to effective and gentle pumping of viscous, shear-sensitive fluids, maceration of residual and waste materials also plays a major role in ensuring the most economical pumping processes.

Thanks to the compact dimensions of Vogelsang pumps, they are ideal for integration within existing production processes. The intelligent lobes minimize vibrations, thereby preventing the formation of foam when pumping blood. Solid and foreign matter can either be pumped without damaging them or they can be shredded. A specifically designed combination of pumps and grinders is provided for this purpose: the RedUnit from Vogelsang. Using an XRipper and a RotaCut, large quantities of dry matter are grinded either finely or coarsely, making them easy to dispose of or use in subsequent processes. The size-reduction ratio is crucial (e.g. for use in biogas plants), as smaller particles provide a better surface area for bacteria, therefore generating more gas.

The connection of pump and shredding technology in one processing step is a specialty of Vogelsang, as the company focuses on the effectiveness and efficiency of its products in the interests of its customers. Because it saves space and power while also being highly effective, the RedUnit is well-established not only in the food industry, but also in the waste management sector worldwide.

Much like meat processing, the treatment and disposal of fish waste is a laborious process as it is subject to strict conditions. In addition to the need to shred bones and heads, etc., by-products such as fish oil and fishmeal must be processed just as carefully as the main product.

Because these processes often take place on board the fishing vessel, the compact design of Vogelsang industrial pumps, as well as the RedUnit with pump and grinder,is extremely advantageous. Fish factories on land also appreciate these space-saving and energy-saving machines. The tough, low-maintenance design has proved to be highly effective and covers all the industry pumping processes due to the many design options, including variants such as stainless steel models for applications in the food sector. Technical additions such as Vogelsang dispensing technology also have had a positive impact.

Whether they are transporting chemicals, oils, or media for the food industry, transportation vehicles need to be filled and emptied quickly and precisely. Here, as everywhere, time is money and an inaccurate dose can be irresponsible or even dangerous. Pumps for tanker vehicles must therefore meet accordingly strict safety criteria and must not be too big or too heavy. These are conditions that often restrict performance.

Due to their compact and yet powerful design, Vogelsang rotary lobe pumps are among the most ordered industrial pumps in the global transport and logistics sector. They can pump highly viscous or aggressive media of all kinds and can even pump fluids with coarse solid matter without getting clogged. This is due to the unique design of Vogelsang rotary lobe pumps, which also enables hassle-free maintenance without the need to dismantle the machine. Not that there is much need for maintenance, since Vogelsang products are extraordinarily robust, without pulsation and with very low wear. Another advantage of rotary lobe pumps on tanker vehicles is their reversible pumping direction. This represents a great advantage over progressive cavity pumps which must be installed in pairs - one for filling and one for draining.

In the ceramic industry, even pumping of typically highly viscous and abrasive media is of great importance. This is because the homogeneity of sludge and glazes determines the quality of the final product. These kinds of slow-flowing media also require a high pumping power, necessitating high speeds and leading to strong shaking and jarring movements, depending on the pump design.

Rotary lobe pumps are pulsation free and more energy-efficient and quieter than air-driven diaphragm pumps commonly used in this industry. Due to their compact design, the Vogelsang models in particular are extremely low-maintenance and easy to service. The product-specific arrangement of the lobes in the housing creates much greater suction force despite low torque, and also allows reversal of the flow direction. This rotary lobe technology is also resistant to dry running and extremely resistant to solid matter and impurities that can occur both in the sludge necessary for production and also in  washing and waste water. This is not only good for the product but also makes sense economically to use Vogelsang industrial pumps in ceramic production.
