Pyroban delivers ATEX pack to power refinery pump 18 April 2012

PumpSets has taken delivery of an explosion-proof diesel engine package from Pyroban for use on an Azerbaijan refinery to power a pump for processed water.

The refinery had ordered a pump for use in a Zone 2 hazardous area, and the unit supplied includes an APEX pump, which can pump water containing traces of oil at a flow rate of 350m3/ hr at 60m head.

To power the pump, PumpSets ordered Pyroban's radiator to flywheel explosion-proof diesel engine package, which was supplied fully built onto a skid, and tested and certified to ATEX 94/9/EC and the Machinery Directive.

The 167bhp (1,800rpm) prime mover, a Perkins 1006.6TW diesel engine, required complete explosion proof modification to ensure that it could not be the source of ignition from hot surfaces, engine overspeed or gas ingestion.

The package included an exhaust gas cooler, an SVG valve to prevent engine overspeed and flame from the inlet, flame and spark arrestors, a water-cooled turbocharger etc – along with a marine radiator designed and manufactured by Pyroban group firm Broadland Radiators.

Pyroban manufactured the complete explosion proof package at its works in West Sussex in the UK and the unit is fully certified to Category 3G T3 IIB ATEX 94/9/EC as a component, based on the standard EN1834-1:2000. With Pyroban's support, PumpSets supplied the complete pumping unit with one ATEX 94/9/EC certificate after final testing.
