A piston pump that processes 25% dewatered sludge feed to the incinerator at a wastewater treatment facility.
A wastewater treatment facility was having problems with particulate and water contaminating the hydraulic reservoir on their piston pump which is used to process 25% dewatered sludge feed to the incinerator. An oil analysis report showed >5% water in the hydraulic oil as well as an ISO code of 22/19/17, these are at unacceptable levels for the piston pump to function properly. Read More »
For a large chemical processing plant, the time had come to consider a major maintenance change. The global supplier of specialty chemicals for making polymers, detergents and personal care products, among other things, knew its multitude of vented oilers could be upgraded to help reduce contamination ingression, something that would save them tens of thousands of dollars a year. The dilemma was finding a replacement that could work with the equipment’s unique configuration.
