What kind of peristaltic pump uses rollers to move chemicals?

The choice of low pressure tubing pumps is correct because these types of pumps specifically utilize rollers to compress the tubing and push the liquid through. In a peristaltic pump, the rollers rotate around the tubing, creating a wave-like motion that effectively moves the fluid inside. This design allows for smooth and consistent flow, making it ideal for transferring chemicals and other fluids without contaminating them, as the fluid only comes into contact with the tubing rather than the pump mechanism itself.

Other pump types serve different functions; for example, high pressure pumps are used for tasks requiring the movement of water or fluid at high pressures, while vacuum pumps create negative pressure to move gases or vapors. Reciprocating pumps operate by mechanically moving a diaphragm or piston back and forth, which is a different mechanism than that of a peristaltic pump. This highlights why low pressure tubing pumps are the type specifically associated with using rollers for moving chemicals.
