Safe Pump Solutions for Waste Mineral Oil and Naphtha Transfer

"A customized solution for every process"

Sector: Recycling & Oil Refining

Application: Waste Oil Recovery & Naphtha Transfer

Product Group: Internal Gear and Magnetic Coupling Pumps

Products: Rotan HD Series | Verdermag Global Series

Situation

Our client, one of Türkiye's leading waste mineral oil recycling facilities, processes waste mineral oils to produce base oil.
The facility's engineering design was carried out by a US-based engineering firm, which acted as a solution partner at many critical points.
This process required specialized pump solutions to ensure the safe transport of both high-viscosity waste oils and flammable and volatile naphtha liquid.

The main challenges encountered were:

  • Waste oils cannot be efficiently transferred with standard pumps due to their viscous nature.
  • Ensuring safety measures suitable for flammable and explosive environments (ATEX certification)
  • Naphtha evaporates rapidly at low temperatures, preventing the risk of cavitation.
  • Ensuring a completely safe transfer process by preventing mechanical seal leaks.

Solution

To address these operational challenges, Rotan HD Series and Verdermag Global Series pumps were integrated into the company's facility.

Rotan HD Series Pumps for Waste Oil Transfer

  • Heavy Duty (HD) Series internal gear pumps are designed with special gear tolerances to reliably transfer high-viscosity waste oils.
  • ATEX certification was obtained in accordance with explosive and flammable environment conditions.
  • After arriving at the facility by tanker, the waste oils were filtered and safely transferred to filling tanks using Rotan HD pumps.

Verdermag Global Series Pumps for Naphtha Transfer

  • Since naphtha is a flammable liquid hydrocarbon that evaporates at low temperatures, Verdermag Global pumps with low NPSH values were chosen to ensure cavitation-free operation.
  • A magnetic coupling design was used to completely eliminate the risk of leakage, thus eliminating the risk of leakage associated with mechanical seals and ensuring maximum safety.
  • The ATEX certified pump group met all the safety criteria of the facility.

Benefits

  • Thanks to internal gear pump technology, smooth and efficient operation was achieved in waste oil transfer.
  • ATEX certified safe solutions were implemented for flammable and explosive environments.
  • Low NPSH levels prevented cavitation risk during naphtha transfer.
  • The magnetic coupling pump design completely prevents leaks and increases the safety level.
  • A sustainable and reliable pump solution was provided, meeting all operational and safety criteria of the facility.

As of today, our customer continues to manage waste mineral oil and naphtha transfer processes with high safety and efficiency thanks to Rotan and Verdermag pump solutions.
