And I replied:

   For  more details on operation principle, max flowrates, max pressures on
   peristaltic pumps (the ones that are using rollers combined with silicone
   or other tubing) visit thye following site: www.masterflex.com

   My  small  business  is  the  maintenance  and  repair of various medical
   equipment and I can assure you that no liquid is flowingback!
