Original Instructions

Important safety Information

Vacuum pumps are potentially dangerous if incorrectly used, repaired or maintained, so please approach the

repair or maintenance with caution.

Any incorrectly fitted spare parts could damage your pump and could be potentially dangerous.

Never allow unqualified personnel to attempt to remove or replace any part of the pump.

If you have any doubts about the servicing procedures or the products capabilities please contact Edwards.

Before returning any equipment to Edwards for repair please follow the Edwards HS1 procedure and

complete an HS2 declaration form to warn of any substances used or produced in the equipment that can be

dangerous. The procedure and forms are included with the pump instruction manuals and can be down-

loaded together with Edwards local contact details from www.edwardsvacuum.com

Always conform to service schedules unless adverse conditions necessitate more frequent servicing.

Report any defect before an accident or consequential damage can occur.

Observe local and country specific regulations, norms and guidelines.

Never allow anyone to remove large or heavy components without adequate lifting equipment.

Before maintenance work is begun, ensure the pump is switched off and isolated from the mains.

The pump may have been exposed to processes which use hazardous substances or produces by-products

which are dangerous to human health and safety, for example, chemically active, biologically active or

radioactive substances.

Before working on a pump, ensure that the correct personal protective equipment is available and being

used. Always wear safety goggles. Wear a breather mask with positive air pressure and take other

precautions if you believe the pump may be contaminated with hazardous substances and dusts.

When applying sealants and lubricants, prevent contact with the skin by wearing suitable gloves.

Seals may contain fluoroelastomer, which when properly handled is not dangerous but which may produce a

toxic and corrosive residue (hydrogen fluoride or hydrofluoric acid) in the event of excessive heat or fire

depending on the circumstances of degradation and other materials involved.

On completion of maintenance, check the pump functions correctly and that all guards and protection

devices are fitted and working correctly and that the pump is electrically safe.

If the pump is used for handling hazardous substances check the pump for leak-tightness before use.

Dispose of waste oil and any process by-products in accordance with local and national safety and

environmental requirements. It is usually illegal to dispose of waste oil into drains or water courses, or to

bury it.

1 Introduction

1.1 Scope of this manual

This manual provides information about the component parts of the Edwards RV3, RV5, RV8 and RV12 rotary vane

pumps, together with the installation instructions for the clean and overhaul kits, the blade kits and the inlet valve

kit for the pumps. You must use the kits as specified in this manual.

Exploded views of a generic RV pump are shown in Section 2, together with a list of the component parts and an

indication of whether the component parts are available as spares.

Section 3 lists the maintenance kits available for the RV pumps.

Use a clean and overhaul kit to replace the springs, seals and elastomer components in the pumps.

Use a blade kit and a clean and overhaul kit when you replace the blades in the pump.

Use an inlet valve kit to replace the inlet valve assembly in the pump.

We recommend that when you use a kit, you use all the components in the kit.

The contents of the kits and how to install them are defined in Section 3.

1.2 Safety

The dynamic seals and O-rings used in these pumps are made from fluorinated materials. Fluorinated materials are

safe in normal use but can decompose into very dangerous materials (which may include hydrofluoric acid) if they

are heated to above 210 °C and above.

The pump may have overheated if it was misused, or if it was in a fire. If the pump has overheated, take extreme

care to avoid skin contact with any part of the pump and to avoid inhalation of the vapours. Health and safety data

sheets for fluorinated materials used in the pump are available on request: contact your supplier or Edwards.

WARNING

Do not touch or inhale the thermal breakdown products of fluorinated materials which may be

present if the pump has been heated to 210 °C and above. These breakdown products are very

dangerous. Some of the seals in the pump are made from fluorinated materials.

2 Parts list

Exploded views of a generic RV pump are shown in Figure 1 to 4. The component parts shown on the figures are listed

in Table 1. When you read Table 1, take note of the following:

Where a G.A. Item is in the form 'XXX-Y', this specifies that the part is a component of a sub-assembly (that

is, the inlet valve, exhaust flange or ballast knob sub-assemblies). In these cases, XXX specifies the sub-

assembly (and may be shown on Figure 1) and Y specifies the specific component of the sub-assembly.

The entries in the 'Kit No.(s)' column are cross references to the kits in Table 2. If a part has an entry in this

column, then the component part is included in the referenced maintenance kit(s).

If a part has an entry in the 'Part No.' column, then the part is available as a spare and the entry defines the

Item Number of the spare part.
