*For NORPRENE®, PHARMED®, and TYGON® tubing. Values will be less with silicone, C-FLEX®, and
Viton-®. Flow rate and discharge pressure will vary based on tubing size, formulation, and operating
temperature. The chart above is only a guide.
‡ Use in this temperature range for continuous duty operation with no decrease in performance or
product life. Pump Heads will work outside this range with some possible reductions in performance
or product life.
