| Flexible pump suction and discharge fluid can be divided into three stages (see the working principle diagram), which guarantees the fluid into the pump chamber (by pump self-absorption capacity or fluid weight) is the premise of normal pump work. From this point of view, the choice of speed is essentially a suction performance issue; especially in high viscosity, if the speed is too high, it will cause inhalation, resulting in noise, vibration; may also lead to motor overload and reduce the use of the impeller Life expectancy and other issues.
In addition to viscosity, the choice of speed depends on several factors: Abrasive suction medium speed should be reduced, this can greatly extend the service life of the pump. Absorption of fragile, shear sensitive media, should be low speed; for example, delivery of yogurt, speed should be 600 rpm below. In addition, it is noteworthy that: the level of the speed of the flexible pump self-priming capacity; in order to maintain a self-priming height of 3 meters above, the speed should be 800 rev / min or more. |

From this point of view, the choice of speed is essentially a suction performance issue; especially in high viscosity, if the speed is too high, it will cause inhalation, resulting in noise, vibration; may also lead to motor overload and reduce the use of the impeller Life expectancy and other issues.
Therefore, as the media viscosity increases, the pump diameter should also be increased, the speed should be reduced accordingly. The flexible pump produced by our company can handle media up to 10000 cps. Perceptually, the medium can be pumped into the pump chamber by its own weight.
The corresponding relationship between viscosity and speed is shown in the following table:
Medium viscosity range (centipoise) | The corresponding maximum speed (rev / min) |
1000 or less | 1400 |
1000-2500 | 960 |
2500-5000 | 700 |
5000-10000 | 600-200 |

About silicone watch bands:
In our life,we may have many watch bands, they are made of metal,golden silver,stainless steel etc.But these materials can cause discomfort for people with sensitive skin.Is there any material for watch band that is suitable for everyone to wear? Of course! That is silicone watch bands! Silicone watch bands is made of Food-Grade silicone,it not only suitable for adult,but also suitable children,even infant! As you can imagine it is so safaty and friendly! Its texture is soft and durable, it can adjust according to your wrist. Don't worry if you dirt it accidentally , it can be clean easily and its dirty resistance is very good!
