Heavy duty pumps

Heavy duty canned motor pumps, designed to be compliant with the American Petroleum Industry specification API 685 for sealless centrifugal pumps, are now available through Michael Smith Engineers.

The Nikkiso-KSB API 685 canned motor centrifugal pump range is suitable for use in the petroleum, chemical, gas and oil refinery sectors and is suitable for transferring hydro-carbons, liquids with a low boiling point, liquefied gases, heat transfer media and liquids containing solids.

Pumps provide flow rates to 360m3/h, heads to 220m, are designed for system pressures to 40 bar and can withstand nozzle movements and forces four times higher than required by API 685.

Pumps have centreline supported casings and wear rings on the casing as well as the casing cover.
