2. Introducon

2.1 Scope and denions

This manual provides installaon, operaon and maintenance instrucons for the RV3,

RV5, RV8 and RV12 Rotary Vane Pumps. The pump must be used as specied in this

manual.

The units used throughout this manual conform to the SI internaonal system of units of

measurement.

2.2 ATEX direcve implicaons

This equipment is designed to meet the requirements of Group II Category 3 equipment

in accordance with Direcve 2014/34/EU of the European Parliament and the Council of

26th February 2014 on the approximaon of the laws of the Member States concerning

equipment and protecve systems intended for use in potenally explosive

atmospheres. (The ATEX Direcve).

The ATEX Category 3 applies in respect of potenal ignion sources internal to the

equipment. An ATEX Category has not been assigned in respect of potenal ignion

sources on the outside of the equipment as the equipment has not been designed for

use where there is an external potenally explosive atmosphere. There is no potenal

source of ignion within the pump during normal operaon but there may be potenal

sources of ignion under condions of predictable and rare malfuncon as dened in

the Direcve.

There is no potenal source of ignion within the pump during normal operaon but

there may be potenal sources of ignion under condions of predictable and rare

malfuncon as dened in the Direcve. Accordingly, although the pump is designed to

pump ammable materials and mixtures, operang procedures should ensure that

under all normal and reasonably predictable condions, these materials and mixtures

are not within explosive limits. Category 3 is considered appropriate for the avoidance of

ignion in the case of a rare malfuncon which allows ammable materials or mixtures

to pass through the pump while within their explosive limits.

When ammable or pyrophoric materials are present within the equipment:

▪

Do not allow air to enter the equipment.

▪

Ensure that the system is leak ght.
