Hazardous waste disposal pumps now run
smoothly
The Mono NOV projects and installation team has recently completed an important improvement to the White Rose Environmental hazardous waste disposal site at the Royal Bolton Hospital in Lancashire
The incinerator facility is a real testing ground for equipment, as proved when the previously installed submersible pumps were prone to failure after a matter of months To rectify the situation Mono provided a complete design approach to offer a more reliable and efficient method of running this important facility

New Mono coating provides answer to rotor abrasion
Mono Pumps, a leading manufacturer of pumps and pumping solutions, has launched Duracoat 3000 - a new surface coating offering increased wear resistance for rotors used in highly abrasive environments
When the hazardous material has been safely burned, the incinerator is periodically emptied of ash by an automated bucket system.
During this process there is an inevitable small amount of spillage.
The spilled ash is washed into a sump which has to be pumped out to maintain a correct level.
Standard submersible pumps, even when constructed in stainless steel, found it hard to deal with the abrasive, corrosive slurry, and in addition to unacceptable short operating lifetimes, they were subject to regular blockages.
Andrew Clewer of White Rose Environmental commented that the Mono approach to this problem was highly professional from the outset.
"Mono came to site and took detailed measurements of the equipment to understand exactly what was required.
The team provided a full method statement and risk assessment for the installation and a solution which fully addressed all the problems that we had been experiencing".
The Mono solution was to install a vertical Compact C range progressing cavity pump, positioned over the sump to suction lift the ash slurry at a capacity of 1.6m3/h and maximum delivery pressure of 0.45 bar.
As the drive forms an integral part of the unit, the pump is ideal for installations where space is at a premium.
The low running speed of the progressing cavity pump reduces wear on abrasive applications and therefore extends the periods between routine maintenance.
The team took total responsibility for design, installation and commissioning of the equipment, which also included the necessary pipe work, valves, hardware, dry run protection and high pressure switch.
