Factors Affecting the Transfer of Viscous Fluids

When it comes to transferring viscous fluids, several factors come into play, affecting both the efficiency and longevity of the pumping process. Through experimental analysis, it has been determined that the concentration and viscosity of the fluid directly impact its adhesiveness, leading to slower transfer rates. Consequently, this can result in challenges for peristaltic pumps, such as difficulty in priming the pump tubing and occurrences of pump wheel spinning without fluid transfer, known as dry running. Such phenomena impose considerable wear and tear on both the pump's operational lifespan and the tubing itself.

One significant effect is on transfer accuracy. Due to the higher viscosity and stronger adhesiveness of viscous fluids, the precision and flow rates of the transfer process may decrease. Moreover, the lifespan of the pump is also affected. As previously mentioned, instances of dry running accelerate the degradation of the pump's components, leading to a shorter operational lifespan.

When purchasing a peristaltic pump, the precision advertised is typically based on water measurements, with standard units being in liters per hour. However, the actual precision may vary depending on the properties of the fluid being transferred. Other equipment used for fluid transfer, such as infusion pumps or gear pumps, may also be affected by the specific nature of the fluid being transferred. In such cases, consulting with sales representatives from reputable manufacturers like Lever can help in selecting the most suitable equipment for your needs.

During prolonged use of the pump, if any abnormal noises occur, it is advisable to dismantle the pump for inspection to determine whether it is due to bearing wear or damage. If not, contacting the manufacturer of the peristaltic pump is recommended. Additionally, it is recommended to lubricate the pump rollers every six months using specialized lubricating oil to maintain smooth operation.

After approximately 220 hours of pump tubing usage, it is advisable to flip the tubing (i.e., rotate it by 90 degrees). Prolonged compression on one side of the tubing can lead to uneven wear and tear, which flipping the tubing can help alleviate, thereby extending its lifespan.

In conclusion, when dealing with the transfer of viscous fluids, it is essential to consider factors such as fluid concentration, viscosity, and their impact on pump performance and longevity. By understanding these factors and implementing proper maintenance procedures, the efficiency and lifespan of peristaltic pumps can be maximized, ensuring reliable fluid transfer operations.
