The propellers are designed with fibre-repellent, self-cleaning blades with backward curved incidence edges and are made of grey cast iron, stainless steel or a synthetic material depending on the fluid to be handled. Main hydraulic tasks Introducing and mixing various gases, liquids or solid substances into a fluid Preventing conglomeration of sludge flakes Circulating phase mixtures Preventing sedimentation in the case of insufficient fluid flow velocity in the tank Aligning the mixer to break 26130 floating sludge layers The applications and 216300 range of hydraulic tasks to be fulfilled by mixers entail different requirements for these machines.

Free to use BIM project management tool provides step-by-step sio to define, manage and validate responsibility for information development and delivery at each stage of the asset life cycle in level 2 BIM projects. They are driven by three-phase asynchronous motors which are safe to run dry.


Again there may be more recent versions of the document. Document Status Indicators The Green document status indicator indicates that the document is: Search A-Z Suche nach. Appropriately designed installation equipment ensures that the forces developing during operation are transmitted to the tank floor.

Mixers are sealed to prevent ingress of water and come either in a close-coupled design or with gear unit. By continuing to browse the web site you consent to the use of cookies. The positioning of the mixer including installation accessories is performed in such a way that it is correctly orientated before being lowered into its working position in a mounting bracket.

Mixers are installed via a guide bracket fitted to the mixer; it allows the submersible mixer to be lowered into the tank along a guide rail. The Amber document status indicator indicates that some caution is needed when using this document – it is either: A mixer can be withdrawn from the tank for repair and maintenance work at any time.

Their committees work with the manufacturing and service industries, government, businesses and consumers to 216330 the production of British, European and International standards. Specific propeller orientation helps create a circumferential flow. The bearings used are maintenance-free rolling element bearings.

Standards Catalogue

Mixers are used for homogenising, emulsifying, dispersing, suspending and flow generation. Mixers are designed for stationary installation on the tank floor or tank wall, or for pedestal mounting.


Mixers consist of the following components: Other mixer types are driven by dry-installed standard motors and medium-exposed shafts. Mixer Mixers are blending devices used in process engineering. The Red document status indicator indicates that the document is an old version The isk has likely been withdrawn by the publisher, also the meta data presented here may be out of date as it is no longer being maintained by the editorial teams at NBS.

Want access to British Standards? The applications and wide range of hydraulic tasks to be fulfilled by mixers entail different requirements for these machines. Establishes guarantees, tests, analysis, measurement of thrust and measurement of mixer electric power uptake.

Mechanical seals are used for sealing on both the product side and the 2130 end. Mixers are blending devices used in process engineering. KGaA uses cookies to be able to optimally design and continually improve its web site. If required, several mixers should be installed in a tank.
