Roller Technology Peristaltic Pump Advantages

In this blog post, we will compare roller technology peristaltic pumps with shoe technology peristaltic pumps. The advantages of roller technology can be listed as follows:

Roller technology peristaltic pumps, where wheels are used to compress the pump hose, are known as roller technology peristaltic pumps. In roller technology, a special teflon-based grease is used between the hose and the roller to reduce friction. In other peristaltic pumps without this technology, metal plates called shoes are used for the same compression process. In shoe technology pumps, the pump housing is filled halfway with special silicone oil to reduce friction. However, due to the higher pressure applied by the shoes on the hose, deformation occurs more quickly on the hose.

Ease of Maintenance: In shoe technology peristaltic pumps, when there is hose rupture or other failures, the operator must completely drain the oil from the pump housing and clean the housing. This is both cumbersome and time-consuming.

Fault Detection: In shoe technology pumps, when the hose ruptures, the transferred fluid and silicone oil mix, creating a contamination risk. Special sensors that measure color differences are used to detect hose failure. In roller technology peristaltic pumps, hose failure can be easily detected with the naked eye, or through a simple, low-cost level sensor placed in the pump housing, which automatically stops the pump.

Operating Cost: In shoe technology pumps, the oil inside the pump housing will mix with the fluid being transferred each time the hose is changed, necessitating a replacement of the oil as well. Especially in large-capacity pumps, the amount of oil used increases according to the size of the pump housing, leading to additional costs for the user.

Safe Transfer: In roller technology peristaltic pumps, there is no risk of foreign substances mixing with the transferred fluid in the event of hose failure. In shoe technology pumps, however, there is always a risk of the silicone oil inside the housing mixing with the transferred fluid.

Energy Cost: In roller technology peristaltic pumps, the friction between the hose and the roller is lower than in shoe technology pumps. Therefore, roller technology pumps require a lower motor power to achieve the same capacity and pressure, making it possible to perform the same transfer with less energy.
