| Maintenance Cost | High (Frequent Failure) | Low (Long-term Stability) |
Frequently Asked Questions
No, this pump is designed for clean water. Pumping sediment, mud, or highly turbid water from new wells can cause premature wear and damage to the impeller and rubber bearings.
The motor uses a water-filled wet structure for cooling and bearing lubrication. Failure to fill the cavity with clean, non-corrosive water will lead to overheating and immediate motor failure.
The pump must be installed strictly vertically. Ensure a minimum distance of 3 meters from the well bottom and ensure the water inlet is at least 1-1.5 meters below the dynamic water level.
Immediate shutdown is required. Vibration usually indicates the pump is running against the well wall, experiencing cavitation due to low water levels, or having an unbalanced electrical phase.
The 175QJR is specifically designed for water temperatures below 100°C. For temperatures exceeding this limit, specialized high-temperature customized materials are required.
We recommend dismantling the pump for maintenance after one year of operation, or if the diving time exceeds two years, to replace impellers and sealing rings.
