Page 3: Wanner And The Atex Directive 2014/34/Eu
Wanner has worked with an outside specialist agency called Intertek in order to obtain ATEX Certification for the T&Q-Series Hydra-Cell pumps, carrying out a comprehensive risk assessment and compiling the Technical File. Intertek is accredited by UKAS (the UK Accreditation Service) and authorised to carry out product safety testing and Certification of equipment under European Directives such as ATEX as well as under the international IECEx scheme. -

Minimum service temperature (°C) Aflas EPDM HNBR This is the maximum temperature range for T-Series Hydra-Cell pump with ATEX. Wanner has obtained Type Certification, for conditions outside the pump as follows:- II 2G Ex h IIC T5…T4 Gb X Group II (Zone 1) Category 2 G (gasses) T5…T4 (auto ignition temperature dependent on process temperature) -

(see product specification sheets on website) at maximum speed and pressure for any given pump . 4. Protection Concept T & Q Series Hydra-Cell pumps are protected by constructional safety and control of ignition source. Constructional safety is ensured by splash lubrication. Control of ignition source is used in the form of an oil level monitoring float switch which ensures the presence of the protective liquid (lubricant). - Page 6 A01-114-3416 severe-duty synthetic oil A01-114-3421 T&Q Series Hydra-Cell pumps are not suitable for total immersion in liquid. Only genuine replacement parts and mechanical components must be used. The chemical and mechanical characteristics of genuine parts only have been considered as part of the risk assessment to ensure explosion safety within the parameter of the ATEX classification herein.

Page 7: Markings Of Conformity - Category 2 Zone 1
6. Markings of Conformity – Category 2 Zone 1 The pump nameplate is Stainless steel and text clearly marked as below in figure 1. Figure 1 - ATEX nameplate markings The nameplate will be positioned on the top of the crankcase. It is fixed with pop rivets to the main crankcase illustrated on the next page in figure 2. - Page 8 (T100 Only) Access hole for testing float switches Oil Drain Figure 2 – Component positions An earth stud is fitted to every T and Q-Series Hydra-Cell ATEX certified pump and must be connected to ground during installation. For some T100 models there is also a secondary earthing point on an ‘ear’ projecting from the back cover gasket.

Page 9: Earth Continuity Checks & Procedure
7. Earth Continuity Checks & Procedure. Checking Procedure. The 2 cables connected to the PAT tester are connected, one to the manifold of the pump and the other to the earth stud, as described in the pictures below. The ‘earth bond’ is then measured on the deflection meter, when the red earth button is pressed on the PAT tester. - Page 10 PAT tester in operation 1 Rev. A 14/10/2019...

Page 11: Oil Level Monitoring Device Installation
8. Oil level monitoring device installation. ATEX T and Q series pumps are supplied with an Ex d flameproof level sensor which is used to monitor the level of oil in the pump and detect a change in level caused by diaphragm rupture. This should be connected to an approved motor shutdown system. -

Electrical installation The connecting wires to the printed circuit board must be between 16 to 22AWG (Metric capacity 1.5mm2) with 6mm stripped ends. The earth wire should be connected to the screw point in the head using the crimp terminal provided. EXd flameproof cable gland for enclosures with internal volume ≥... -
