Safe, hermetic fluid metering and a maintenance free drive for air, gas as well as sour gas are the features of the PKH diaphragm metering pump. It is used for oil, gas and liquefied gas treatment as soon as a pneumatically operated pump for inhibitors, odourants and other additives is required. The flowrate of the standard pump is 0 to 8 l/h at 300 bar max. It has a zero-leakage operating chamber sealed by a diaphragm. Diaphragm support on both sides secures against overpressure and run dry operation. The drive module consists of stainless steel with resistant seals and operates without diaphragms and springs. The automatic switch-over operates the driving cylinder directly via the 1.5 to 14 bar supply pressure to produce the suction and discharge stroke.
