Pyroban has supplied an explosion proof diesel engine package to PumpSets Ltd for use in a refinery application in Azerbaijan to power a pump for ‘processed water’.

The international oil company in Azerbaijan has ordered an explosion proof processed water pump unit from UK pump manufacturer PumpSets Ltd for use in a Zone 2 hazardous area.  The unit 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 a radiator to flywheel explosion proof diesel engine package from Pyroban which was delivered fully built onto a skid frame, tested and certified to ATEX 94/9/EC and the Machinery Directive.  The 167bhp (1800rpm) prime mover, a Perkins 1006.6TW diesel engine, required a complete explosion proof modification from Pyroban to ensure that it could not be the source of ignition from hot surfaces, engine over-speed or gas ingestion.

The Pyroban explosion proof diesel engine 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 and other safety critical components. The Pyroban explosion proof package also included a marine radiator designed and manufactured by Pyroban Group Company, 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 were able to easily supply the complete pumping unit with one ATEX 94/9/EC certificate after final testing.

Diesel engines are widely used in the oil and gas industry, upstream and downstream, where there is a risk of hydrocarbon release.  Today, more companies are ensuring the safety of their people, the environment, their brand and production levels, by insisting on full explosion protection for diesel engines operating in hazardous areas.

Pyroban is an international group of companies providing a wide range of explosion protection safety services and products to the oil and gas sector, including hazardous area consulting, training, components, mobile equipment conversion and engineering support.
