ABSTRACT
The article looks at the fire hazards from failed oil sealed pumps from vacuum conveying of powders. It lists the causes of risks such as powder ingress into the pump that blocks the oil mist filters, and running with open ports for long periods of time. It also offers solutions to address the problem such as changing the pump type to a liquid ring vacuum pump which uses water to provide the seal, and the use of hook and claw pump which could lower the risks. It adds that a high level of maintenance work could minimize risks of accidents.
