(Summary description)  The pressure of the peristaltic pump is determined by the pressure pipe gap and the characteristics of the tube.   To understand this problem, we first need to understand how the peristaltic pump produces pressure. Peristaltic pump is to rely on roller extrusion tube to transport liquid, in order to prevent liquid reflux, must always remain sealed, with sealing on the corresponding will produce a certain amount of pressure. The looser the pressure pipe, the lower the pressure, the longer the life of the tube; conversely, the tighter the pressure pipe, the greater the pressure, tighter to a certain extent, with the roller rotation, the tube will cause wear and tear, tube life will be shorter.

Information

  The pressure of the peristaltic pump is determined by the pressure pipe gap and the characteristics of the tube.

  To understand this problem, we  first need to understand how the peristaltic pump produces pressure. Peristaltic pump is to rely on roller extrusion tube to transport liquid, in order to prevent liquid reflux, must always remain sealed, with sealing on the corresponding will produce a certain amount of pressure. The looser the pressure pipe, the lower the pressure, the longer the life of the tube; conversely, the tighter the pressure pipe,  the greater the pressure, tighter to a certain extent, with the roller rotation, the tube will cause wear and tear, tube life will be shorter.                                       

  In addition, there must be a certain error in the tube  produced by  different manufacturers, even if the tube produced by the same manufacturer, there will be a (+ 0.1 mm) deviation. For peristaltic  pumps, these  deviations are enough to cause a great difference in peristaltic pump pressure. In practical applications, some peristaltic pump designs will increase the function of pressure regulation to adapt to the size differences   between different manufacturers.                                 

  In addition, the material  and wall thickness of the tube directly affect its bearing capacity. The greater the stretching and tearing strength of the tube, the thicker the wall thickness, the greater the bearing capacity of the tube, and the greater the pressure it can reach.                                                                

  Normally, the peristaltic pump pressure range for tubes with a wall thickness of 2.4 mm or less is about 0-0.25 Mpa, and the peristaltic pump pressure range for tubes with a wall thickness of 4.8 mm or more is about 0-0.6 Mpa.                     

  If the pressure required by the customer is greater than 0.6 Mpa, it is not recommended to use peristaltic pump. The main advantage of peristaltic pump is hygiene, no cross-contamination, but it is not as good as plunger pump and gear pump in dealing with very large pressure problems.
