Optimal pumping of liquid manure
Rotary lobe pumps - the foundation of spreading technology

For more efficient liquid manure spreading, generally the liquid manure first needs to be pumped from a deep sump into a tanker or into another container on the yard. Farmers and corporate contractors require efficient pumping technology that is geared precisely to their requirements. At the same time questions like "How do I best pump liquid manure?", "How can I pump large quantities in a short time?" or "Which pump is suitable for mobile use?“ play an important role here.

Rotary pumps as all-round solution

Rotary lobe pumps have become an essential liquid manure technology due to their fundamental characteristics and are the basis of spreading technology. As the inventor of this technology, Vogelsang is further optimizing its various pump series on an ongoing basis to ensure our products meet the daily requirements of our customers.

Vogelsang pumps are self-priming up to a depth of nine meters so that liquid manure can also be pumped out of deep sumps to a container or tanker. Together with their high performance, they make the tanker filling process simple and fast.

The pump process can be performed using a stationary solution with a liquid manure pump installed on a fixed-position or three-point stand, or else at the tank. There are three drive options (mechanical, electrical, hydraulic) from which each farmer can select.

Use of the liquid manure pump at the tanker

Rotary lobe pumps for tankers being self-priming and high-performance does not suffice alone however. Being compact, having no dependency on direction of rotation, and resistance to foreign matter are additional key features that make rotary lobe pumps the optimal solution. The compactness and low dead weight of the Vogelsang liquid manure pump enables a greater useful load at the tanker, while at the same time filling the tank more quickly and fully. In this way, storage capacities are utilized optimally and transport is as efficient as possible. Vacuum systems arrive at their physical limitations very quickly e.g. due to formation of foam in the tanker. In addition, rotary lobe pumps can fill tanks up to 30 percent quicker than other pumps.

Rotary lobe pumps vs. vaccum

The filling technique at the tanker can also be used for draining. The rotary lobe pump spreads the liquid manure constantly and evenly, regardless of the liquid or pressure level in the tank. This is a basic prerequisite in order use liquid manure as a natural and organic fertilizer. Simple and fast servicing of the pump is also important to ensure downtimes are kept as short and rare as possible. Our QuickService concept means Vogelsang liquid manure pumps can be repaired without dismounting and have a high maintainability.

Support of the vacuum tank with filling aids

A further variant for tank filling is the vacuum system. When filling with a vacuum pump, the basic problem is foam formation. The filling process also requires more time than other techniques. But an auxiliary filling aid will enable you to lessen both disadvantages of this technique. The Vogelsang PowerFill enables this power at a significantly lower speed due to its generously sized housing, ensuring less formation of foam overall with significantly faster filling. The PowerFill can be inserted both on the suction and the discharge side and can be retrofitted easily using a flange connection.

Stationary and mobile filling stations

Use of tank filling stations is one option for stationary tanking, for example with tanks or terminal storage on a biogas plant. These remove the need for inconvenient, time-consuming coupling and decoupling of hoses since they are equipped with a dome including a filling nozzle enabling the tank to be filled quickly via the dome. There are also mobile filling stations for comfortable and rapid filling on the border of the field. Vogelsang offers two options for filling tanks quickly and conveniently with the FillMaster S for stationary tanking and the FillMaster M for mobile tanking.
