The actuation fluid used (water/glycol) is suitable for this application. Because of reduced thermal conductivity of the hose-diaphragm material, the fluid temperature will be reduced in the transition area between fluid chamber (inside of hose-diaphragm) and actuation chamber. Furthermore the pump casing is emitting heat to the environment so that the temperature of the actuation fluid is uncritical. If hose-diaphragm / flat diaphragm monitoring systems and valve performance monitoring systems (FVPMS) are installed, cleaned and maintained correctly, they are well suitable for the job. As you know, these systems have been supplied with hundreds of pumps all over the world and are working to customers¡¯ satisfaction. Serious pressure pulsations and noises have been caused by partly using inoperable pulsation dampeners. Hose-diaphragms have been removed by customer or the bladders have been emptied or pre-charged to a pressure which was inappropriate to the working pressure. This had been criticized by us in the past several times, however, no reaction from customer¡¯s side. Therefore, please inform customer again to run the pump only with pulsation dampeners which are in proper condition. FELUWA is not responsible for damage of pump and gearbox due to customer¡¯s faulty operation |
