Pump Seal system for Russian chemical plant

As part of an upgrade of the Nevinnomyssky Azot urea processing plant in Russia, a new Flowserve pump was required. The steam condensate media and low ambient temperature made it essential for the pump’s shaft seal system to provide accurate regulation of both temperature and pressure. This was because if the temperature of the steam condensate were to drop too low the urea would begin to crystallise, which could damage and ultimately destroy the seal. The Eagleburgmann seal system installed in this application maintains the shaft seal by holding a greater pressure than that exerted by the

Pump lubricating oil systems for El Merk oil and gas field, Algeria

Walton temperature control valves have been selected for a demanding application at the El Merk oilfield in the Algerian Sahara. This is a remote, harsh and hot desert location where the terrain consists of large interlocking sand dunes. Walton have supplied valves to control the temperature of lubricating oil systems for  eleven massive water injection pumps. These are used to maximise output from the oil and gas wells, which will be critical to the successful operation of the $4bn El Merk field. The lubricating oil systems have been designed as an integral part of the pump package
