Diaphragm Metering Pumps

GRUNDFOS allDOS product informationddi 222The digital diaphragm dosing pump for difficult liquids?DDI ???the Highlights • Easy input and display of the dosing rate in l/h or gal/h with perfect calibration for optimum operating convenience and unparallelled levels of precision• Smooth, nearly continuous dosing ensures a high process quality and optimal mixing of liquids• For especially viscous liquids, there are ? Slow Mode steps and special valve combinations• Hotkey for easy query of the dosed quantity allowing optimal control of the consumption of chemicals• Low energy costs thanks to the EC motor technology with maximum ef-ficiency• Pump excess pressure control by digital input of the maximum backpres-sure allowed before the pump stops• High process reliability thanks to the double diaphragm system• Radical reduction in variants and spare parts: 1 motor, 1 gearing and ? dosing head sizes fit the complete pump series• Adjustment range 1:800• Various possibilities for individual customer applications, e.g. contact or analogue signal control, batch or timer dosing• Analogue and digital interfaces without extra chargeDDI model ???-60 D display on the sideDDI model ???-60 Dwith Flow Monitor for control of the dosing head pressure and the dosing flowDDI model ???-60 D with Profibus DPdouble diaphragm system with diaphragm control for protection of the pump in case of diaphragm leakageStandard: ddi model 222 with double diaphragm technology• If there is a working diaphragm defect, the pump contin-ues to dose with the robust protective diaphragm. option: with diaphragm control• For applications where the process must not be inter-rupted in the event of a diaphragm leakage, a differential pressure sensor is optionally available. • In the event of a working diaphragm leakage, the sensor immediately sends out a signal, while the pump continues to dose with the protective diaphragm.digital doSing™?DDI ???pump types• Connections, cable and Euro plug included• Strokes per minute: maximal 180 in normal operation or maximal 1?0 in Slow Mode 1 or 74 in Slow Mode ?normal operation Slow mode step 1 Slow mode step 2 Vstrokeddi modelQ [l/h]pmax [bar]Q [uSg/h]pmax [psi]Q [l/h]pmax [bar]Q [uSg/h]pmax [psi]Q [l/h]pmax [bar]Q [uSg/h]pmax [psi][ml] (p = 3 bar)60 10 15.87 145 40 10 10.58 145 24.7 10 6.5? 145 6.6? 222-60d150 4 ?9.68 58 100 4 ?6.46 58 62 4 16.40 58 1?.9 222-150d23017561.5105123B3B4A3A4C1C4H2H3172.5207(159) 16.5Ø79.77D1A5Version for high-viscosity liquids (HV)ddi models a3 a4 B3 B4 c1 c4 d1 H2 H3 c1 c4 d1 H2 H3222-60d ?7? ??6 1?7 – 58 ?6 G 5/8” ?5? 15? 90 ?9 G 1 ¼” ?46 14?222-150d ?15 ?7? 1?7 1?9 90 ?9 G 1 ¼” ?65 179 90 ?9 G 1 ¼” ?65 179Drilling schememeasurementsAll measurements in mm measurements4DDI ???technical datainput of the dosing capacitydigital – by regulation of the dosing stroke speed adjustment range: from 0.1?5% to 100% of the maximum dosing capacityconnectionsmaterial of connection ddi model 222-60d (dn 8) ddi model 222-150d (dn 20)PVC PVC hose 6/1?
