PRODUCT OVERVIEW                                                                                 

   The hydraulic diaphragm metering pump has been developed for handling corrosive liquids and those containing suspensions of abrasive solids. The movement of the fluid is transmitted by means of flexible diaphragm to the liquid to be pumped. The only moving parts of the pump that are in contact with the liquid are the valves, In the hydraulic diaphragm metering pump, movement of the diaphragm is produced by hydraulic force in stead of a direct piston.

   SIKO MPH hydraulic diaphragm metering dosing pump is a hydraulically actuated diaphragm metering pump specially designed for accurate, completely leak-proof metering of difficult-to-handle liquids. Separate chambers for hydraulic fluid and gear lubricant make possible the use of the best medium for hydraulic diaphragm pulsing and the best medium for gear lubrication. The results are better pump performance and longer pump life. This diaphragm pump is available in both simplex and duplex models and is field convertible from simplex to duplex.

FEATURES                                                                                                  

   Seal without leakage: Liquid is completely isolated by the diaphragm, so pump have 100% proof of leakage. It is very good for the viscous, poisonous, corrosive liquid handing.

   Long service life: The diaphragm is not directly connected with the piston; the diaphragm will be much more long-lived. And also it allow much higher pressure than the mechanical type

   Insides safety valve: For measuring accuracy, each pump will be installed with safety valve, air release valve and surge valve; this is also useful for pump safety, absorbing liquid impact.

   Double diaphragm: For safety, pump can be in double diaphragm type with an alarm system; it will stop the pump and give an alarm signal, when one diaphragm breaks.
