Frequently Asked Questions

What are the key advantages of EOSi rotary screw vacuum pumps for continuous industrial production environments?

EOSi rotary screw vacuum pumps offer dry, oil-free compression - eliminating process contamination risk - with high pumping speeds suitable for large-volume industrial processes. Their key B2B advantages include: lower maintenance costs versus oil-sealed alternatives (no oil changes, no oil disposal), high energy efficiency (particularly with VSD models), tolerance of small liquid carry-over, robust construction for 24/7 operation, and quiet operation suitable for indoor industrial environments.

How do EOSi rotary screw pumps compare in total cost of ownership to oil-sealed rotary vane pumps for industrial applications?

While rotary screw pumps typically have a higher initial capital cost than oil-sealed rotary vane pumps, their TCO over a 5-10 year operational period is often lower due to: elimination of oil purchase and disposal costs, reduced maintenance labour, higher energy efficiency (especially at partial load with VSD), and longer mean time between major services. Ezzi Vision can provide a TCO modelling analysis for your specific process and duty cycle.

What process gas compositions can EOSi rotary screw vacuum pumps handle safely?

EOSi rotary screw pumps can handle a range of process gases including air, nitrogen, inert gases, and gases with moderate water vapour content. For corrosive gas applications, material upgrades (coatings, seals) may be required. Ezzi Vision's engineering team should be consulted when process gases include: halogens, acids, reactive chemicals, or explosive/flammable gas mixtures - to confirm suitability and any required modifications.

Can EOSi rotary screw vacuum pumps be integrated with our existing plant PLC and SCADA systems?

Yes. EOSi rotary screw pump systems are available with variable speed drives (VSDs) and digital communication interfaces (including Modbus, Profibus, or 4-20mA analogue) that integrate with standard PLC and SCADA platforms. This enables remote monitoring, speed control, alarm management, and energy optimisation as part of your plant automation architecture. Ezzi Vision can advise on integration requirements.

What is the installation footprint and utility requirement for EOSi rotary screw vacuum pumps?

EOSi rotary screw pumps are compact relative to their pumping speed, with most industrial models requiring a footprint of 0.5-1.5 m2. Utility requirements include: single or three-phase electrical supply (depending on motor size), adequate ventilation (or cooling water for some configurations), and inlet/exhaust connection piping. Ezzi Vision can provide detailed installation drawings and utility specifications for your facilities planning team.

Does Ezzi Vision offer commissioning and operator training services for EOSi rotary screw vacuum pump installations?

Yes. Ezzi Vision provides on-site commissioning services and operator training for EOSi rotary screw vacuum pump installations. Training covers: safe start-up and shutdown procedures, routine maintenance tasks, fault diagnosis, and VSD parameter configuration. Training documentation can be customised for inclusion in your facility's standard operating procedures (SOPs).
