Cast Steel Electric Diaphragm Pump

Product Description

• Diaphragm expansion creates negative pressure to suck fluid; contraction generates pressure to discharge fluid, with one-way valves ensuring unidirectional flow;

• The diaphragm isolates the medium from the motor/drive parts, achieving 100% leak-free operation.

• Cast Steel Durability: Pump body made of high-strength cast steel (e.g., ASTM A216 WCB), resistant to impact, high pressure, and mild corrosionsuitable for heavy-duty industrial use;

• Electric Drive Convenience: No compressed air required, easy to connect to industrial power systems for continuous stable operation;

• Medium Adaptability: Handles clean liquids, low-viscosity slurries (particles 3mm), and mild corrosive media (e.g., mineral oil, industrial wastewater);

• Low Noise & Maintenance: No mechanical seals, low wear, and quieter operation than pneumatic models.

• Flow Range: 5 m/h - 50 m/h;

• Max Discharge Pressure: 1.2 MPa (12 bar);

• Temperature Resistance: -20 - 130;

• Motor Power: 0.75 kW - 5.5 kW (three-phase AC, 380V/220V optional).

• Mechanical Manufacturing: Lubricating oil, cooling fluid circulation;

• Petrochemical: Transfer of light oil, diesel, and non-strong corrosive intermediates;

• Water Treatment: Industrial wastewater, circulating water transfer;

• Mining: Conveying of low-concentration mineral slurry, cleaning water.
