KEY FEATURES AND BENEFITS

WET PUMPING

Fundamental benefits of Edwards RV pumps for "wet" applications:

Highest vapour pumping capacity amongst rotary vane pumps.
Pump maintains lubrication at a high flow due to the distinctive mode selector switch
Gives a 220g/hr (290g/hr on RV12) water vapour handling capacity due to the highest gas ballast flow amongst all rotary vane pumps.
Optional oil return kit to ensure the oil remains in the pump at high flow

A nitrile (Buna-N) conversion kit is available for applications where there is incompatibility between vapours and fluoroelastomer (FKM) seals. Moreover, for pumping large quantities of oxidants, PFPE pumps may also be ordered.

DUSTY

Fundamental benefits of Edwards RV pumps for "dusty" applications

For preventing the dust getting back into the process, the Edwards RV pumps have premier anti-suck back protection. For removing pressure surge, there is a controlled opening by oil pressure.Quick closing within 0.4 seconds of pump stopping due to dump valve

Clogging is avoided by having a large diameter in oil passages (3-5mm)
There are diameters less than 1mm in oil passages in some competing pumps.

The Edwards range of RV pumps are perfect for dusty applications and are designed using the experience of CVD and PVD applications from the semiconductor industry.

CLEAN/DRY

Fundamental benefits of Edwards RV pumps for clean/dry applications

Pump maintains lubrication at a high flow due to the distinctive mode selector switch
Optional oil return kit to ensure the oil stays in the pump at high flow
For preventing the oil mist getting back into the process, the Edwards RV pumps have premier anti-suck back protection.
For removing pressure surge, there is a controlled opening by oil pressure.Quick closing within 0.4 seconds of pump stopping due to dump valve

The pioneering mode selector function on the pump indicates that the pump will work well in both high vacuum applications and high throughput application. An optional oil return kit can be fixed to allow continuous operation for high throughput applications without losing oil down the exhaust line.

OXIDANTS

Key benefits of Edwards RV pumps for pumping oxidants:

Highest gas ballast of any rotary vane pumpAllows dilution of pumped gases to minimise oxidation of the oil
PFPE variants availableIdeal for pumping oxygen and halogenated compound

The RV pump is an ideal pump for oxygen because it maintains dilution to a level lower than the explosive limit. When the optional oil return kit is fitted, the gas ballast is prevented from blowing oil into the exhaust. Oxidation of the oil is avoided by the PFPE prepared pump.

This is the reason why oxidants such as halogens and halogenated compounds can also be pumped using the RV pumps. In that case, a gas ballast is useful for the protection of oil and bearings even though there is no fire/explosion issue with the same. PFPE must be used to prolong the life of the pumps.

Frequently Asked Questions

What is the recommended preventive maintenance schedule for oil-sealed rotary vane pumps in industrial production environments?

For production environments, recommended preventive maintenance for oil-sealed rotary vane pumps includes: oil inspection and change every 2,000-3,000 hours (or sooner if contaminated), inlet filter replacement every 6 months, exhaust filter/mist eliminator check every 6 months, and a full internal service (vanes, bearings, shaft seals) every 20,000-30,000 hours. Ezzi Vision's service team can set up a scheduled maintenance programme tailored to your operating hours and process conditions.

Can Ezzi Vision supply Edwards RV rotary vane pumps with a service and maintenance agreement?

Yes. Ezzi Vision can arrange service agreements for Edwards RV and E2M rotary vane pumps in production or research facilities. Agreements can cover scheduled oil changes, annual inspections, priority breakdown response, and discounted parts supply. Contact their service division to discuss a service level agreement (SLA) suited to your operational requirements.

What oil specification should be used in oil-sealed rotary vane vacuum pumps for pharmaceutical applications?

In pharmaceutical applications, hydrocarbon pump oils may be unacceptable due to contamination risk. PFPE (perfluoropolyether) oils - such as Fomblin or Krytox - are the industry standard for pharmaceutical, food, and oxygen-compatible applications. They are chemically inert, non-flammable, and approved for sensitive process environments. Ezzi Vision supplies appropriate pump oils alongside their rotary vane pump range.

Are refurbished rotary vane pumps from Ezzi Vision suitable for research facility use and do they come with a warranty?

Yes. Ezzi Vision's refurbished rotary vane pumps - including Edwards RV and E2M series - are fully rebuilt to manufacturer specifications by trained technicians, performance-tested, and supplied with a warranty. They are a cost-effective option for research facilities managing tight capital budgets. Warranty terms and full test documentation are provided with each refurbished unit.

What are the energy consumption implications of running multiple oil-sealed rotary vane pumps in a research facility?

Oil-sealed rotary vane pumps consume power proportional to their pumping speed - typically 0.15 to 5 kW for laboratory-scale models. In a facility running multiple pumps continuously, energy costs can be significant. Ezzi Vision can advise on right-sizing pumps for actual process demands, installing gas ballast correctly, and whether transitioning to more energy-efficient scroll or dry pumps would reduce operating costs at your throughput levels.

How should waste pump oil from rotary vane pumps be managed in accordance with Australian environmental regulations?

Used pump oil is classified as hazardous waste under Australian environmental regulations and must not be disposed of via standard waste streams. It must be collected by a licensed waste oil recycler. Ezzi Vision recommends establishing a regular oil collection schedule with a licensed operator. In some states, contaminated pump oil (e.g. containing solvents or process chemicals) requires specific hazardous waste disposal. Consult your state EPA guidelines.
