摘要： A pulsation damper configured to reduce pressure variations in a pipe system. The pulsation damper comprises a first pipe section and a second pipe section. The first pipe section is at least partly placed inside the second pipe section such that a product flow can flow through the first pipe section and then through a space formed between the first pipe section and the second pipe section. Due to the increased cross sectional area of the second pipe section pressure variations can be damped efficiently.

摘要： A membrane arrangement to be placed between a product chamber and a hydraulic oil chamber is provided. The membrane arrangement comprises a first membrane and a second membrane. Between the membranes in a membrane interior space a marker liquid is placed. By using a sensor it can be detected when product or hydraulic oil enters the membrane interior space, which in turn means that a rupture of any of the two membranes may be detected in a reliable and cost efficient way.

摘要： A pulsation damper configured to reduce pressure peaks in a pipe system. The pulsation damper comprises an elastic pipe section arranged to be in a small volume state or a large volume state. A first volume held in the elastic pipe section in the large volume state is greater than a second volume held in the elastic pipe section in the small volume state. The elastic pipe section has an elliptical cross section in the small volume state. A ratio between a major axis and a minor axis of the elastic pipe section is in the range 1,05 to 10,0, such as 1,1 to 1,5.

摘要： A homogenizer valve seat member comprising a valve seat plate is disclosed. The valve seat plate has two end surfaces perpendicular to the central axis, and the seat plate has a peripheral seat zone for sitting in a homogenizer housing. The valve seat member comprises a plurality of holes extending axially through the valve seat plate, wherein at least one hole of the plurality of holes forming a continuous mouth edge on one of the end surfaces. The central axis of the valve seat member is positioned outside the mouth edge. A forcer, a homogenization device, and a method for homogenization are also provided.
