A submersible water pump in Wellington New Zealand is effective for certain tasks. Companies from different industries use submersible pumps. Municipalities use submersible pumps as a filter or to drain local ponds. Cities may use them for draining sewage. Alternatively, construction companies may use submersible pumps if their worksite has standing water. Disaster relief organizations may use submersible pumps to control flooding.
The uses of submersible pumps go beyond the examples mentioned above. Just like anything else, a submersible pump can experience issues. If you would like to learn the common issues with these pumps, we have got you covered in this guide.
Overheating and temperature fluctuations
The most common problem with submersible pumps is overheating. A submersible pump may overheat for various reasons. One possibility is that you are pumping hot liquids either unknowingly or knowingly. Another possibility is scale or ocher buildup which reduces the flow of water, thus reducing the cooling capability of the motor. If you don’t know, a submersible pump cools itself by operating. When the water flows through the pump, the water acts as a coolant. If the coolant is reduced, it is likely that the motor will be starting and stopping frequently and this will result in overheating of the motor.
Pumping very hot liquids may damage the internal components of the motor and pump. Most submersible pumps have several bearings that provide thin films of water between various surfaces of the submersible water pump. If the liquid you are pumping is too hot then the components will reach a boiling point and this can diminish the small water film. When the film deteriorates from the heat, the internal components can get into contact and this produces heat quickly. This might sound like the hot water is the problem but it is not. The problem is likely to be from the submersible pump itself. Not all submersible pumps are designed to pump hot liquids. Before you pump hot liquids, you need to check the working temperature range of the pump to ensure it is capable of pumping the liquid.
Inadequate voltage
A submersible pump requires an external source of power. There are two common issues with voltage as far as submersible pumps are concerned. These issues are imbalance and voltage spikes. Voltage spikes are very common during storms because lightning can cause a jump in voltage. The spike causes an excess current that the pump and motor cannot handle. This results in overheating and a pump failure. You can avoid using your pump during storms if possible or you can invest in the right surge protector. With a voltage imbalance, a disproportionate voltage supply is merely due to an electrical issue that is unrelated to the pump.
Water hammer
A submersible water pump Wellington can also experience a water hammer. This is when there is a sudden change in the flow of the liquid. When the velocity of a liquid change suddenly, the pump will experience a surge in pressure. The surge can damage the thrust bearing and cause pump failure. You can prevent hydraulic loading by installing check valves to prevent backflow. You can also prevent hydraulic loading through regular maintenance.
