Choosing the Right Dispenser: Peristaltic Pump or Venturi?

The full automation and intelligence of the wet cleaning machine are not only reflected in the fact that the washing program can be edited by oneself, but also in the automatic addition of detergents. It is an important manifestation of its intelligence.

All the detergents needed during the washing process are automatically added by the dispenser: corresponding detergents can be added at different steps of the washing process. The Kingstar wet cleaning machine’s automated material interface can be connected to various types of dispensers.

Peristaltic Pump vs Venturi

At present, there are two main types of dispensers used in wet cleaning machines on the market: peristaltic pumps and Venturi. What are the differences between these two types of distributors in terms of usage, and what are their advantages and disadvantages? Let’s analyze it together.

Advantages

Peristaltic pump:

Peristaltic pumps are relatively inexpensive. They have stable flow characteristics and are also relatively easy to maintain.

Venturi:

The Venturi is driven directly by water pressure through fluid dynamics (saving energy by over 30%).

Unlike peristaltic pumps, it does not reduce the feeding amount over time. In addition, the Venturi has no mechanical moving parts and has a longer service life.

Disadvantages

Peristaltic pump:

The maintenance cost of peristaltic pumps is relatively high. During the peak laundry season, the hose needs to be replaced on average every six months. Moreover, there is a tendency for residue inside the hose, which may cause the detergents added to the wet cleaning machine to be inaccurate. Additionally, the residual detergents may clog the hose.

Venturi:

The Venturi dispenser requires a stable water pressure. The more stable the water pressure is, the more accurate the addition of detergents will be. Therefore, for laundries with unstable water pressure, if the wet cleaning machine wants to use a Venturi, a booster pump needs to be installed to ensure accurate flow.

In addition, the Venturi can only add one type of detergent at a time, while the peristaltic pump can add several types simultaneously.

Conclusion

Then the laundry shop can consider which dispenser to choose based on its own actual situation. To sum up, it is:

The price of peristaltic pump equipment is relatively low, and several detergents can be added simultaneously. However, the drawback is that the maintenance cost in the later stage is high.

The later maintenance cost of the Venturi is low, but it has certain requirements for water pressure.

Both types of dispensers share a common feature: they can only add liquid detergents, and powder cannot be added through the dispensers.

Kingstar Design

Kingstar wet washing machine is specially designed with a powder detergent box, which can be used to add powdered detergents. It can also be edited in the program. When in use, it is only needed to add the detergents to the corresponding box before the washing starts.

The powder detergent box of the Kingstar wet washing machine adopts the siphon principle, which can add all the detergents into the bucket without leaving any residue. Through the above analysis, everyone may have already gained a preliminary concept of how to choose the appropriate dispenser.
