    Working Principle

    1. At pump inlet, due to the inner eccentric structure of pump stator, partial vacuum between the blades of flexible impeller will  be formed when volume is increased. The consequently formed suction will draw liquid into pump chamber.

    2. The rotating impleller was carried the liquid from inlet to outlet. At this stage the space between blades actually was kept constant. The gap between blades allows big solid particles to pass through the pump and without damage on liquid.

    3. The impeller is contacted with the flat part of the eccentric inner surface in pump stator. Whne impeller is bent, the volume between blades will be decreased continuously and evenly from the pump.

    Advance design , simple construction 

    Maintenance i smple and economical. The pump cover is fixed by four locking nuts. When maintaining the impeller and shaft seal of the pump, just need to unscrew the nuts .



    Mechanical Seal :

    We adopt single mechanical seal, sealing surfaci is carbon-metal ceramics, service life is extended. In food sanitary application, mechanical seals are designed to be cleaned sasily and to be avoided grooves where may be formed with sediment by liquid. 


    Flexible solution for liquid conveying


    1. Donjoy is committed to improve the flexible impeller pump. The application range for RX pump is being expanded by the improvement of pressure resistance, the innovatin design of pump body and shaft seal, and the application of new impeller materials

    2. Excellent self priming function :Flexible impeller pump, with easy operation, is volumetric pump with excellent self priming function which could reach 6 meter 

    3. Moderate Pumping: The pumping effect of RX pump is very stable and moderate, the medium won't be whipped and damaged. even if it's fragile media like high fat butterfat, big berry, even if it's half size of peach, could be passed through the pump without damage. Meanwhile our RX pump could be guaranteed to run without pulsation completely. It also could be used as dosing pump by adjusting pump pseed . 

    4. Smple operration, low maintenace cost : Compared with other typical self priming pumps, such as pneumatic diaphragm pumps and variable volumetric pumps, the operating cost of RX pump is lower, maintenance is more simple and downtime is shorter, just need to disassemble front cover by using standard wrench, maintenance could be done on the flexible impeller pump, more importantly, there is no need to detach the pump from piping system. 



    RX application of sanitary 

    Hygiene is of paramount importance in the processing of food and dairy products. The RX is designed with polished stainless steel and food or milk grade impeller to meet rigorous hygiene requirement. The stainless steel sanitary RX is easy to clean, which use unsoltted shaft seal that dose not cause liquid deposition and the used impeller material has been tested and approved. and is certified to comply with FDA regulations. Typical products suitable for delivery by the pump including: Milk, skimmed milk, cream, curds,youghurt, whey, lumps, syrup, condiments, gelatin, honey, jam, ointment, canned food, beverage, wine, beer, fruit juice and spices.


    RX application of Industry

    RX flexible impeller pump also could be applied to the situation without sanitary requirement, however, it is still as main stainless steel pump.RX stainless steel pump is particularly suitable for conveying acidic liquids, clays, concrete additives, detergents, dyes, film processing chemicals, ink and sewage treatment cosmetic are also pumped in this type of pump frequently, including the following products: soap,shampoo, detergent, and moisturizer.

    Can this pump run dry?

    No, definitely not! Flexible impeller pumps will incur damage even after short periods of dry running. The mechanical seal requires lubrication and cooling while the pump is operating. Without the presence of fluid, the mechanical seal will overheat and crack, and this may cause the pump to leak and fluid to enter the motor. There is also the possibility that the motor will burn out. The rubber impeller may also melt or deform even after short periods of dry running. Our advice is to ensure that the pump always has access to fluid while running, the vessel or sump on the inlet side of the pump must never run out of fluid while the pump is active. Level sensors or a float switch can be installed in the fluid chamber ensuring that the pump is turned off in the event there is no fluid. Another way of protecting the pump is to fit a dry running device, this will turn the pump off if it detects that no fluid is entering the pump. If you think that dry running is inevitable, then please speak to us and we will try to select a more suitable pump for your application.
