Delivery pumps are most commonly used either to pressurize water from an atmospheric tank, to deliver purified water to a specific point of use, or simply to increase water pressure when required.These diaphragm pumps are controlled by a pressure switch. When required, an integrated bypass can be incorporated to help regulate pressure levels.Materials of Construction:Nylon HousingEPDM ValvesSantoprene DiaphragmStainless Steel FastenersApplications for E-CHEN Delivery/Transfer Pump:Water TreatmentReverse OsmosisBeverageFood ServiceDistillation EquipmentAgricultural SprayingGeneral IndustrialAutomotiveVolt:24 VDC (12 VDC available)Amps:2.0 AFlow:3.0 L/MinPorts:3/8″Prime: ≥2 MRecommend Accessories:- E-CHEN 5A transformerSHIPPINGNet Weight:2.3 Kg eachCarton Weight:6 each, 19 KgCarton Size:44 X 34.5 X 32.5 cmE-CHEN Delivery Pump RV Series ModelMODELINLET PRESSUREOPEN FLOWON / OFF PRESSUREVOLTAGERATED CURRENTEC-RV-02L0 psi2 l/m0.2 Mpa / 0.45 Mpa24 VDC≤2AEC-RV-03L0 psi3 l/m0.2 Mpa / 0.45 Mpa24 VDC≤3AEC-RV-05LF0 psi5 l/m0.2 Mpa / 0.45 Mpa24 VDC≤5AEC-RV-07LF0 psi7 l/m0.2 Mpa / 0.45 Mpa24 VDC≤8AEC-RV-10LF0 psi10 l/m0.2 Mpa / 0.45 Mpa24 VDC≤10AEC-RV-12LF0 psi12 l/m0.2 Mpa / 0.45 Mpa24 VDC≤10A
