Very gentle pumping

How about function for extracting sensitive medium? Rx's suction function is very smooth and gentle, and does not scrap or damage products, even the medium is as fragile as high-fat cream. Large berries, even half the size of a peach, can pass through the pump undamaged, and RX pump is guaranteed to run completely without pulsation. By adjusting the pump speed, it can also be used as a dosing pump.

●DONJOY is committed to improve the flexible impeller pump. The application range of RX pump (flexible impeller pump) is being expanded by the improvement of pressure resistance, the innovative design of pump body and shaft seal, and the application of new impeller material.
●Excellent self-priming function
    Flexibe impeller pump (RX), with easy operation, is volumetric pump with excellent self-priming function which could reach 6 meters.
●Wide application range
    Because of structure, RX pump could get water drawing effect nearly when conveying viscous liquid, so it's with wide range of application.
●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 a 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 speed.
●Simple operation, low maintenance 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.

Excellent self-priming characteristics

The flexible impeller pump (RX) is simple to operate. It is a volumetric pump with excellent self-priming performance, can reach 5 meters.

Wide application range

The RX pump, efficiency of conveying viscous liquid is close to drawing water, so the application range is wide.

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.

The rotating impeller 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.

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