Larox Flowsys peristaltic pumps' single-roller design can be more effective and cost efficient than sliding-shoe or double-roller designs. The Larox single-roller design compresses the rubber hose once every 360-degree revolution as opposed to multiple times with sliding-shoe and double-roller designs.
These types of pumps cannot run continuously at high rpms, so they must be shut off in order to cool down, which is not ideal or even possible in some cases. Some processes will operate two pumps at the same time to compensate for the down time, which is costly.
The single roller allows the pump to run at much higher rpms, and it eliminates 80% of the friction and heat caused by sliding-shoe designs, requiring only a fraction of the glycerin, extending hose life and potentially saving money.
A 3-inch single-roller design pump requires 2.2 gallons of glycerin to operate as opposed to 10 gallons for a sliding shoe design. At $85 per gallon, users can potentially save $663 in glycerin costs alone on each hose change with the single-roller design.
