Feature:1. The utility model has a simple structure and adopts a sealing structure combining a valve ball and an elastic cross-shaped stop pin, which is convenient to process2. The sealing effect is good, which can ensure the long-term efficient operation of the diaphragm pump3. By installing an overpressure automatic pressure relief device on the pump body, the structure is simple4. With oil resistance, heat resistance, acid resistance, alkali resistance, corrosion resistance, wear resistance and other properties5. Small size, small current, high pressure and low noiseSpecification:Item Type: Backflow Diaphragm PumpModel: FL3210H-80W (1/2 inch threaded pipe, right water outlet)Material: Engineering PlasticDrive Mode: ElectricUses: Boost pumpPump Shaft Position: HorizontalImpeller Structure: Closed impellerNumber Of Impellers: Multi-levelImpeller Suction Method: Single suctionPrinciple: Diaphragm pumpPerformance: Corrosion resistanceTransmission Medium: Clean water pumpSpeed: 4800 (r / m)Power: 0.08 (KW)Protection Pressure: 80-120PSIHeat-resistant Temperature: 60℃Flowing Rate: 3.5-5 liters / minControl Type: Intelligent pressure switchMotor: Permanent magnet DC motorVoltage: DC12VThread Diameter: 1/2 inch = 12.7mm.Package List:1 x Backflow Diaphragm Pump
