Working Condition Limitations of YW Liquid-Submerged Sewage Pump

To guarantee stable long-term operation of YW Liquid-Submerged Sewage Pump, users must comply with factory specified working condition limits, over-limit operation will cause accelerated wear or sudden pump failure:
（1）Medium Temperature Range: -15℃ ~ 60℃, medium temperature exceeding 60℃ will damage mechanical seal rubber components and motor insulation.
（2）Medium Density: ≤1.3×10³kg/m³, excessive density will lead to motor overcurrent overload.
（3）Medium PH Value: Standard cast iron pump adapts pH 5~9; liquid with pH outside this range must select stainless steel YWP anti-corrosion model.
（4）System Working Pressure: ≤0.6Mpa, high pipeline pressure causes seal leakage risk.
（5）Operation Head Restriction: Cannot run long-term under head lower than 60% rated head, motor overheating burnout risk exists.
（6）Submerged Depth Limit: 0.5m ~ 7m, too shallow depth leads to air suction cavitation; over 7m depth causes excessive extension shaft vibration.
（7）Solid Particle & Fiber Limit: Max passing particle diameter 50% pump caliber, fiber length within 5 times pump caliber; oversized sundries will block impeller channel.

Before project model selection, test actual medium parameters to confirm matching YW pump specification, avoid equipment damage caused by exceeding working condition limits.
