Ensure the chemicals to be pumped are compatible with the pumphead, lubricant (where applicable), tubing, pipework and fittings to be used with the pump. Please refer to the chemical compatibility guide which can be found at: www.wmftg.com/chemical. If you need to use the pump with any other chemical please contact Watson-Marlow to confirm compatibility.

Potential pump hazards As part of the requirements of ATEX Directive 2014/34/EU all potential hazards, including expected malfunctions, have been identified and subjected to a risk assessment. In order to prevent these ignition sources becoming hazardous, a number of changes have been implemented. In addition to engineering modifications, the changes include comments in these instructions in order to specify correct usage in hazardous locations.
Installation Preliminary checks DANGER! - EXPLOSION HAZARD Failure to inspect the pumphead unit for damage or check the ATEX labelling data may cause a fire or explosion. Check the label on the pump to ensure that the pump type and the ATEX labelling conform to the planning of the plant or machine.
All Watson- Marlow ATEX rated pumpheads include provision for the prevention and dissipation of electrostatic charge. In order to dissipate electrostatic charge effectively there must be sufficient electrical contact between the pumphead and the suitably earthed drive. It is imperative that the 500, 600 and 700 series ATEX pumps are earthed. The pumphead guard, track, gearbox and motor and baseplate (where applicable) already have earth straps installed.

Tube selection: The chemical compatibility lists published in Watson-Marlow publications are guides. If in doubt about the compatibility of a tube material and the duty fluid, request a Watson-Marlow tube sample card for immersion trials. PB0448:m-501-621-701atex-en-01...
Start-up If the unit has been supplied integrated with a air filter, lubricator and regulator then please refer to the manufacturers instructions as supplied, in conjunction with the recommendations in the air motor operating manual. Please refer to the pumphead instructions to ensure correct loading and operation of the pumphead. Prior to start-up ensure that the tubing material used is listed in the "Special conditions of use for safe operation - Tube materials suitable for use with this equipment"...
Maintenance The pump should be cleaned regularly to avoid the accumulation of dust, this will prevent build up of electrostatic charge due to the presence of dust. This product is not certified for use in ATEX dust environments. Visually inspect the earth straps monthly to ensure mechanical integrity. Electrical conductivity of the earth system must be verified six monthly.
ATEX marking The pumps have been marked with the following labels: 050.8652.L20 501Df/Rl2A Atex Eexd 223rpm IP55 0.18kW Ptcs 230/400V 50/60Hz 3Ph Issue No.: 6 Serial No: 123456-987654 13.1 Equipment Group II for above ground areas (surface) Equipment Category 2G (Gas) - Zone 1 Ex h Ignition protection labelling for mechanical devices Group IIB –...
