1. Replace the seal ring: Following long term usage in the sewage moderate, the gap between the impeller and the seal ring can grow, leading to the reduction of the flow speed and efficacy of the water pump. Turn off the button, lift the water pump, then remove the bottom cap, and then seal the reduced ring , as stated by the true size of this impeller ring using seal ring, then the gap is usually approximately 0.5mm.
2. In case the submersible sewage pump isn't employed for a very long time period, it needs to be cleaned and raised up in a dry and ventilated location. Look closely at antifreeze. If put in water, operate for a minimum of 30 minutes each 15 days (can't be dry) to look at its role and adaptability. Assess the cable at least once annually, and replace it if it's damaged.
3. The submersible sewage pump has recovered appropriate quantity of engine oil prior to leaving the mill to lubricate the mechanical seal. The engine oil ought to be checked once per year. When water is found in the oil, then it needs to be emptied, the petroleum replaced, the gasket replaced, along with the screw plug. After three months, it has to be re-examined. If the oil becomes emulsion back, the mechanical seal ought to be inspected and replaced if needed.
