Safety in mining means protecting miners as well as the environment. Centrifugal pumps play critical roles in dewatering, movement of chemicals, and removal of slurry. These pumps are asked to perform in the most demanding of conditions, including unpredictable intake levels - one of the leading causes of pump overheating. Whether dewatering or delivering chemicals, mining pumps are susceptible to blockage of intake and discharge causing loss of prime and deadheading: pumps without enough water to cool themselves effectively or with water trapped in the pump housing and unable to leave, causing overheating. Failure of any of these pumps can lead to catastrophe, including deaths and longterm environmental impact.
Most pumps offer overheat protection for the pump MOTOR. While this may protect the windings of the motor against damage from overheating, it does nothing to protect the pump and discharge pipes. Protecting the motor has nothing in common with protecting the pump: these are two separate systems and must be protected separately from each other.
For mining applications, Thermal Interrupt Devices recommends use of our 1-Amp Pump Protector for pumps with control panels. The 1-Amp Pump Protector also offers the capability to integrate with remote management and monitoring circuits. Our 25-Amp Pump Protector can be installed on pumps with direct wiring to the pump motor. Any of our Pump Protectors will work with any size pump, preventing costly and dangerous mining pump meltdowns. Thermal Interrupt Devices can create custom temperature range protection and custom connection types to suit all forms of mining pumps. Pump Protectors stop pump motors without wasting valuable water or energy.
Whether you are a mining pump service company seeking to provide your customers with the best in pump overheat protection or a mining organization with a desire to protect miner's safety and demonstrate a commitment to clean environmentally-friendly operations, the Pump Protector can be retrofitted to existing pumps or added to new builds.
