RL N/GE

Applications & Specific Features

  • Pump for ‘Ring Main’ oil transfer systems.
  • Single or multiple appliances at same height or varying height.
  • Suitable for high output or modulating burners.
  • For use on oil supply installations where a GP ‘dead leg’ system is not practical.
  • A back pressure relief valve (overflow valve) is required to maintain adequate pressure in the ‘Ring Main’.
  • Special RL units available for aggressive or heated non standard fuels.

Accessories and adaptations

  • IM system to stop pumps when all burners are off (optional for RL-N)

  • Free voltage relay output to control from centralised Building Management System, in kit 3, 4 or 6 signals (2-thermal, motors 1 or 2 ON, low pressure and Leak safety ON).

  • GSM alarm system by SMS messages, or connection to modem.

  • Adaptation of Pressure Group for high pressure, working conditions of up to 6,5 Kg/cm2

  • Leak collector trays with infrared detectors (standard in RL-4 and above).

  • Modifications to adapt to specifically regulated environments (tropicalised equipment or ATEX.)

  • Solenoid valves with flow limiters, to automate filling in supply tanks for electrical generators.

  • Soundproof sheet cabinets with UNE-2
