Low Pressure Diaphragm Metering Pumps KD series are spring type mechanical diaphragm metering pumps. The stroke movement is controlled by the spring and the eccentric mechanism. The adustment stroke length rate from 10%-100%. Key features: ●Compact and economic design.●Multilayer compostie PTFE diaphragm , long service life.  ●Reinforced plate design after the diaphragm.●Flow adjustment by the micrometer manually.●Fluid max temperture:   70℃(158℉)Materials ●Pump head: PVC, PTFE,SS304,SS316   ●Diaphragm: PTFE         ●Check Valve: PVC, PTFE,SS304,SS316 (same as pump head selection)●Valve ball: Ceramic●Valve seat: PTFE,SS316   Voltage Supply 380V on standard, others on request;Parameter TableModel50Hz60 HzPressurePower      kWFlow      (lph)Flow      (gph)SPMFlow      (gph)Flow      (lph)SPM(Bar)(Psi)KD 15/0.8154.0484.8185881160.18KD 20/0.820548624588116KD 40/0.840119613481158116KD 60/0.6601648197258687KD 80/0.68021962596115687KD 120/0.5120329638144115573KD 180/0.518047.614457.1216173573Standard ConnectionModelPVCPTFESSKD15~KD406.5*10mm PE hoseRC 1/2"F6*12mm welding unionKD60~KD180DN15RC 1/2"F10*16mm welding union
