Submersible pumps play a vital role in managing wastewater, particularly in demanding environments such as those with oily water. Improper pump maintenance or operation can result in equipment failure, safety hazards, and costly repairs. To help you prevent these issues, we’ve compiled 11 crucial tips for using submersible pumps in oily wastewater applications.
The 11 essentials tips when applying submersible pumps in oily wastewater include:
Oily wastewater often contains chemicals that can corrode or degrade pump components. Ensure that the pump’s materials - such as its casing and impellers - are resistant to oil and chemicals. Stainless steel or specific plastics are popular choices for such conditions.
Seals protect the motor from contamination, which is vital in oily environments. Ensure you use oil-resistant seals or double mechanical seals to create a tight barrier against leaks. This small precaution can significantly extend the life of your pump.
If the wastewater contains volatile substances, safety is paramount. Choose an explosion-proof pump, like our GPVH Series Hazardous Area Sump Pumps, that adhere to relevant safety standards to mitigate the risk of ignition in hazardous areas.
Pumps are not designed to handle high concentrations of oil alone. An upstream oil-water separator can help remove excessive oil, reducing the strain on the pump and ensuring efficient operation.
Oily wastewater often has a higher viscosity than standard wastewater, which can reduce pump efficiency. Select a pump designed to handle thicker liquids to ensure optimal performance.
Oily wastewater frequently contains solids or sludge that can clog standard pumps. A pump with a non-clog impeller or a vortex impeller design can help manage these materials effectively.
Pumps operating in demanding environments are more prone to overheating. Install thermal overload protection to safeguard the motor and avoid downtime caused by equipment failure.
Oily environments can cause rapid wear and buildup on pump components. Opt for a pump with easy access to critical parts, enabling routine maintenance and cleaning to keep the system running smoothly.
Handling oily wastewater often involves strict environmental regulations. Ensure your pump system complies with local laws regarding wastewater disposal to avoid fines and environmental damage.
Monitoring devices, such as oil-in-water sensors, help track the levels of oil in the wastewater. These systems provide real-time feedback to ensure your pump is operating within safe and efficient parameters.
Standard power cables can degrade when exposed to oil over time. Choose oil-resistant cables to prevent short circuits and ensure a longer lifespan for your pump system.
