Submersible mixers with gear drive Series AR

FEATRUES OF STANDARD VERSION OF AS MIXERS

• Propellers geometry guarantees maximum efficiency while maintaining energy consumption on low level; self-cleaning design, special shape of blades prevents solid particles from settling down;
• Propellers for smaller AR mixers (propeller diameter up to 900 mm) entirely made as one-piece stainless steel cast; casting technology Allowi us to pro duce propellers featured with diversified thickness of blades, this feaute improves generated thrust significantly; propellers are available In two versions: with two or three blades;
• Propellers for bigger AR mixers made of synthetic resins reinforced with glass fibres; their advantage is very low weight, even in case of biggest models of diameter up to 2500 mm; also mechanical hardness is very high; two blades;
• Two independent leakage sensors located in motor chamber and cable terminal case; due to its arrangement sensors guarantee detection of even smallest quantities of liquids; related electronic modules allows to switch off a mixer immediately;
• Three bimetal thermo-contacts, located at each of motor’s phases, contacts stop the motor if temperature limit equal to 145 Celsius degrees is exceeded; Winding of the motor covered with double insulation layer of class F;
• Electronic module cooperating with leakage and temperature sensors; purposed for installation within control cabinets located around mixers. Each electronic module is composed of controller and power feeder. Electronic modules gather signals from sensors and send appropriate information to central control system;
• Helical reducer conveys power from motor to propeller; maintenance free model, bearings’ durability calculated for 100 000 working hours;
• Mixer’ s body and covers made of grey cast iron, covered with multilayer, double component epoxy coating; strong resistance against corrosion;
• Mechanical SiC/SiC seal, located In Buffet chamber filled with oil; effectively protects against leakage from the front side;
• Labyrinth and lip seals protects the double mechanical seal against bad impact caused by solid particles; significantly improve mixer’s life-span and malfunction-free period; additional seals between reducer and motor’s body;
• All static connections sealed by means of O-rings packs, additiona lly assured with Loctite sealant;
• Power cable of 10 m length, made of special materials, capable for long operations in submersion, even in aggressive environment.
• Cable gland providing Total leak resistance and securing cable against being accidentally pulled out;
• Solid design guarantees high mechanical durability and long-term, malfunction free exploitation under any conditions;

AVAILABLE OPTIONS OF AR MIXER
