The wobble ring pump compared with other positive displacement pumps

The wobble ring pump is a very efficient pump that is used in many industrial applications.

Wobble ring pump Is a very efficient Pump Which is used in many industrial applications. It works ideally with high-viscosity substances and viscous or viscous and solid-containing media. The wobble ring pump is a type of positive displacement pumps , in which a rotor is arranged in a housing. The rotor consists of two or more rings that are attached to each other. But what actually distinguishes the wobble ring pump from other positive displacement pumps?

How does the wobble ring pump work?

The Oscillating Ring Pump from pumpsystems has an annular piston. This is rotatably arranged on a shaft. The whole is arranged obliquely to the axis of rotation. A dividing wall ensures that the wobble ring does not rotate around the axis of rotation. This then creates the tumbling movement. The Wobble Ring Only Moves in the Spherical Pump-Housing . This Movement Results in the Pumping medium Is sucked in. It is then transported through the pump chamber. Within the Pump Chamber, there is a so-called separating sword, which shields the pressure and suction sides from each other.

In addition, the wobble ring pump has an angled cut Pumpenkopf . This helps with dismantling and thus makes it immensely easier. The Wobble Ring is attached directly under the pump head using a ball disc. A bearing cap, directly on the pump head, provides additional shaft bearing. The two connection flanges, each on the left and right of the pump housing, are very easily adaptable to the various requirements of the systems. It is not only possible to select this one connection type. The Wobble Ring Pump is also available with Milchrohr As a connection, as well as a Camlock and TriClamp connection. The medium has only very small contact surfaces inside the pump housing and the pump chamber. As a result, there is little dead space and cleaning is very easy.

The drive motor has an ideally adjustable motor output, with various transmission stages. The surfaces that come into contact with the product are made of inox and made of corrosion-free material. The pump head can be optimally adapted to a wide range of systems in steps of 90°. The pump can be set up horizontally, vertically and even mobile.

About our industrial pumps


Wobble ring pumps have a conveying capacity of up to 50,000 l/h and have 15 bar at differential pressures between suction and pressure sides.

If highly viscous media are transported, it is possible to use a frequency converter (FU) to rpm to regulate.

CIP/SIP (Clean In Place/Sterilization In Place) cleaning is very easy with the wobble ring pump. Wobble ring pumps have the necessary connections for such a cleaning system.

Which pumps also belong to the positive displacement pumps?

All positive displacement pumps are hydrostatic and conducive. Hydrostatic machines ensure that still liquids and gases remain in balance despite external forces. Conveying is carried out depending on speed and almost completely independent of pressure. Displacement pumps are often very different in terms of pumping process and construction. However, they all promote similar media.

Displacement pumps are particularly useful when viscous or media with solid particles , must be conveyed gently.

Like the wobble ring pump, all other positive displacement pumps are made of stainless steel, have no dead space and are quick and easy to clean.

Displacement pumps should have a surface quality of Ra < 0.8 to ensure all hygiene standards to fulfill. A surface quality of Ra < 0.8 means that no product residues remain inside the pump. Contamination of the pumped medium is avoided as a result.

All these regulations come from the so-called Hygienic Design . Hygienic design determines how well or poorly a system is to be cleaned. This includes a number of things, such as the presence of joints, crevices or holes, which make cleaning significantly more difficult. In addition, it must be ensured that the surfaces can easily come into contact with the cleaning agents to be used. CIP/SIP (Clean In Place/Sterilization In Place) cleaning is also part of the basic idea of hygienic design. It is recommended on seals to abstain. If this is not possible, hygienic design is also subject to strict sealing requirements. Seals on positive displacement pumps must then be mechanical seals and have O-rings.

In addition to the wobble ring pump, the diaphragm pump a positive displacement pump. Die diaphragm pump impresses with its particularly leak-free pump design . In general, the diaphragm pump is particularly resistant to continuous stress and contamination of the pumped medium. However, they are not suitable for high pressures. However, the wobble ring pump has no problem with that. It works easily with a delivery pressure of up to 15 bar and is still extremely gentle on the pumped medium.

Die piston pump is also a self-priming positive displacement pump. The advantages of the piston pump are, for example, its good efficiency . Efficiency is used to define the relationship between absorbed and released energy from the pump. The pulsating delivery of the piston pump can cause problems when pumping certain substances. This is because large units require a lot of space, mass and investment costs. The wobble ring pump, on the other hand, impresses with its flexible and even space-saving installation. She is also special energy efficient , low pulsation and resource-saving.

The so-called eccentric screw pumps Like the wobble ring pump, are ideal for pumping highly viscous, viscous pumping media. These can include, for example, fluids such as crude oil, manure and sludge. However, they are not resistant to dry running - but have a high degree of efficiency.

Die gear pump Is a type of pump the rotary piston pumps. It is particularly impressive due to its particularly high durability. It is also very robust and easily conveys media at very high pressures. It manages to convey and dose evenly greasy and highly viscous liquids. With a gear pump, a distinction is made between two different pump types . It is available as an internal and external gear pump. Both can withstand high pressures and can generate large suction heights. The gear pumps are also highly efficient.

Die peristaltic pump is a pump that does not require valves. As a result, it is very easy to sterilize and there is no risk of contamination due to dead spaces that are difficult to clean. It is also very suitable for continuous operation. Compared to other positive displacement pumps, the peristaltic pump has a relatively shock-free delivery. Unfortunately, the hose life is not particularly long and there is a great risk of hose damage when transporting chemical substances.
