Truflo Pumps’ explosion-proof submersible pumps are IECEx certified for hazardous areas where explosive gases and vapours may be present. The series covers six models, from 200 L/min at 25m to 2,000 L/min at 110m, and every model is wound for 1000V mining supplies. Safety gets the pump into the mine. Performance keeps the mine dry.
What does IECEx Certification Mean for Underground Mining Pumps?
IECEx certification shows that a pump has been assessed against international standards for equipment used in explosive atmospheres. IECEx certificates are recognised by 36 member countries and widely accepted in over 50 countries worldwide. The Truflo Pumps series was designed, engineered and tested over almost ten years, with certification through the Safety in Mines Testing and Research Station (SIMTARS).
Each pump has its power cable connected through an IECEx certified cable gland – the gland conforms to IEC 60079-0 cable retention requirements.
Can These Pumps Handle Abrasive Water?
Yes – the impellers are cast from high chromium iron for wear resistance in slurry and corrosive fluids. Replaceable wear rings and a hardened suction cover extend the life of the wet-end. External hardware is stainless steel, and the motor housing is cast iron. The shaft seal runs in an oil chamber, with lip seals keeping the pumped fluid away from the mechanical seals. 
How are the Shaft Seals Protected From Water and Abrasion?
The shaft seals sit in an oil-filled chamber, isolated from the pumped fluid, so water and abrasive solids are kept out of the oil chamber and motor housing. Depending on the model, a pump has two mechanical seals or a single mechanical seal backed by a lip seal. Either way, the design keeps the mechanical seals away from the pump’s operating pressures, which extends seal life. The oil lubricates and cools the seals, and the chamber acts as a buffer against water reaching the motor.
Can the Pump be Serviced Underground?
In most cases yes. The pump is designed for easy and fast maintenance, with no special training or tooling required.
