KNF liquid diaphragm pumps are very chemical resistant, with a choice of premium PTFE or polypropylene materials.        Advantages of KNF diaphragm liquid pumps   

• Maintenance-free operation reduces cost of ownership   * Long lifetime improves your product reliability   * Self-priming for ease of use   * Runs dry indefinitely without fear of damage   * Stable flowrate over lifetime improves instrument accuracy   * Premium chemical resistance prevents damage and excessive pump maintenance   

  Replaces peristaltic pumps   * KNF liquid pumps use no tubing within the pump; peristaltic tubing will fail and leaves a mess to clean up   * Flow is constant thruought the life of a KNF pump; peristaltic performance is affected by tubing fatigue   * KNF pumps are more compact , more powerful than equivalent peristaltic pumps   * Mount a compact KNF liquid pump on location, in any position and close to where you need it, not on the floor like a heavy, bulky peristaltic pump.
