KELAIR says its Sandpiper 3” metallic ball valve pump was used in the repair of an oil processing facility in Brisbane.
According to Kelair, pumps with clamp-band designs can fail when pumping liquids with low specific gravity and low viscosity, because they tend to seep through small breaches in the sealing area.
The Sandpiper air operated double diaphragm pumps have a fully-bolted design that promotes sealing capability.
Kelair says the Brisbane oil processing facility was using a clamp-band AODD pump to transfer the oily sludge from its storm-water collection tanks to a reprocessing facility around 300m away.
During operation, one of the transfer pump’s clamp bands vibrated loose. This had the potential to cause the entire unit to come apart.
Kelair supplied a Sandpiper 3” metallic ball valve pump, whose fully-bolted design helped minimise leaks, and ensured component parts correctly align during assembly after maintenance.
Kelair claims that even if one of the bolts works its way loose during service, any leak will be minimal because the other bolts maintain the pump’s integrity.
For the particular application, Kelair used Teflon diaphragms to resist the abrasive foreign matter that can find its way into the thick and viscous sludge as it collects in the various sumps around the site.
