Peristaltic (hose) pumps

Peristaltic / hose pumps are designed for pumping chemicals and viscous liquids. Peristaltic pumps for pumping liquids flowing through flexible tubes .

Peristaltic pumps have several advantages:

  • There is no contact of the pumped medium with moving metal parts - the hose is the only part in contact with the pumped material
  • Peristaltic pumps have the function of self-suction in the suction-lift mode
  • Volumetric pump function - accurate material consumption per revolution - dosing
  • Simple installation requirements, no risk of cavitation
  • Soft contact with the medium - does not mix or crush material

The principle of the peristaltic pump:

Rollers squeeze the walls of the hose, forming a plug that moves along the hose as the rollers move, while the previously passed section is straightened and fluid is drawn into the vacuum.

The fluid will move along the hose until until it is completely repaired, at this moment, to prevent the fluid from returning, the second roller starts to move along the hose, which acts in a similar way. At the same time, scooters moving with the help of a special electric motor create both the intake force and the pump outlet pressure.

The main advantage of peristaltic pumps is that the transported fluid is in contact only with the working tube, and not with the pump parts, which guarantees a long pump life.
