P2.x AMEX 2 Safety instructions 2.1 Important advice This unit may only be used if: – the product is being used under the conditions described in the operating- and system instructions, used according to the nameplate and for applications for which it is intended. Any unauthorized modifications of the device will void the warranty provided by Bühler Technologies GmbH, –...
P2.x AMEX 2.2 General hazard warnings This product has no dangerous ignition sources when observing regulations and operating parameters in these operating in- structions. Installation into a complete system can pose new hazards the manufacturer of this sample gas pump has no control over.
Page 10
P2.x AMEX DANGER Explosion hazard Life and explosion risk may result from gas leakage due to improper use. a) Use the devices only as described in this manual. b) Regard the process conditions. c) Check tubes and hoses for leakage. DANGER Adiabatic compression (explosion hazard)! In case of adiabatic compression, high gas temperatures may occur.
P2.x AMEX 3 Transport and storage Only transport the product inside the original packaging or a suitable alternative. The equipment must be protected from moisture and heat when not in use. It must be stored in a covered, dry and dust-free room at a temperature between -20 °C and +40 °C (-4 °F to 104 °F).
P2.x AMEX 4 Installation and connection Check the equipment for damage before installation. Among other things, this could be a damaged housing, supply cables, etc.. Never use equipment with obvious damage. DANGER Diffusing pumped media Explosion hazard! Formation of explosive atmosphere due to escaping flammable gases. When operating the sample gas pumps with media that tend to diffuse strongly, such as hydrogen (H ) in high concentrations, it is essential to note that these are not perman-...
P2.x AMEX 4.1.1 Outdoor installation The sample gas pumps were not specifically designed for outdoor setup. The operating and environmental conditions are cru- cial for the required types of protection and any additional measures required, such as: – adequate protection from the weather –...
P2.x AMEX 4.3 Special condition moist sample gas Applications where the sample gas is still moist may result in condensate forming in line and the pump body. In these events the pump head must be suspended (pump body facing down). If the pump was not ordered this way, it can easily be converted on site.
P2.x AMEX 4.4 Connecting the gas tubes The pumps are fitted with the connections you have selected (not pre-assembled for sample gas pumps P2.x AMEX-O2). Com- pare the item number on the type plate with the item number structure in the Introduction [>...
P2.x AMEX 4.4.1.2 Monitoring measures when conveying flammable and/or toxic gasses Conveying flammable and/or toxic gasses further requires continuous monitoring of the sample gas pump during operation. This can be done as follows (1) or (2). Flow rate monitor before the pump’s gas inlet and after the gas outlet. A sudden reduction of the suction volume / flow volume ahead of the pump and consistent or suddenly increased flow volume after the pump indicates a defective bellow (the pump can convey ambient air suctioned in due to the tear).

P2.x AMEX The terminal box has a Ø22 mm bore for installing a 1/2" NPT cable fitting as per NEC Standard requirements. Ensure the con- necting cable has adequate strain relief. The supply line and earth cross-sections must be adjusted to the rated current. Use a minimum line cross-section of 1.5 mm. Be sure to connect the following protective earth terminals to your on-site earth conductor in line with local regulations: –...
P2.x AMEX 5 Operation and control NOTICE The device must not be operated beyond its specifications. DANGER Danger of explosions, danger of poisoning from poisonous corrosive gases During maintenance work, depending on the medium used, explosive and/or poisonous corrosive gases could escape, and this could lead to a danger of explosion or could be hazardous to health.
P2.x AMEX 5.1 Switching on the sample gas pump Before switching on the unit, check that: – the hose and electrical connections are correctly installed and not damaged. – no parts of the sample gas pump have been removed (e.g. the cover). –...
P2.x AMEX 6 Maintenance When performing maintenance work on the unit, the unit must be cooled down and in a non-Ex zone. In particular, cleaning work with compressed air may only be carried out in a non-Ex zone. During maintenance, remember: –...
Page 21
P2.x AMEX DANGER Use appropriate tools According to DIN EN 1127-1, the operator is responsible to select and use appropriate tools. Application in explosive atmosphere Combustible gases and dust may inflame or explode. Avoid the following hazardous situations: Electrostatic charge (spark formation) Clean plastic parts and labels with damp cloth only.
Page 22
P2.x AMEX CAUTION Contamination of cleaned components With sample gas pumps P2.x AMEX-O2 (item no.: 42.....-O2), contamination with oil, grease, dust, particles, lint, hair, etc. must be ruled out for fire protection reasons when working on components that come into contact with media. If necessary, adapt your op- erational and organisational measures with regard to the work clothing to be used, hy- giene regulations, etc.
P2.x AMEX 6.1 Maintenance schedule Component Interval in operating hours Work to be performed To be performed by Pump body screws After 500 h Tighten screws to 3 Nm Customer Complete pump Every 500 h Check hose connections, protective and con- Customer trol devices, proper function, dirt, tightness.
P2.x AMEX 6.2 Inspecting the bellow NOTICE When following preventive maintenance according to the maintenance plan, a crack in the bellows is a rare malfunction, but cannot be completely eliminated. NOTICE If the bellow cracked, turn the pump off immediately! NOTICE If flammable gases (even above upper explosion limit (UEL)) or toxic gases are supplied, continuous monitoring of the pump is mandatory.
P2.x AMEX 6.3 Replacing bellow and connecting rod-eccentric-combination NOTICE Restrictions for connecting rod-eccentric replacement The individual replacement of the eccentric, connecting rod or bearings is not allowed. Only the factory pre-assembled connecting rod-eccentric combination is suitable for re- placement by the operator. Please refer to assembly drawing 42/025-Z02-01-2 in the appendix for this help with this maintenance.
P2.x AMEX 6.4 Replacement of the O-ring of the bypass valve (optional) Please refer to assembly drawing 42/025-Z02-01-2 in the appendix for help with this maintenance. – Loosen the two bolts (24) and carefully pull the entire unit consisting of valve plate (23), spindle (22) and O-ring (21) on the knob (26), out of the pump body (13).
P2.x AMEX 6.6.2 Cleaning the motor Depending on the operating conditions of the pump, the following routine work is required: – Check the terminal compartments and terminals are clean. – Verify the electrical connections are tight. – Clean ventilation paths. –...

Sample gas pumps optimized for use with high-purity oxygen Gas Analysis Applications with oxygen: Free from particles, oil and grease For use with high-purity oxygen, the product requires special cleaning to ensure that it is free from oil and grease, as oxygen is a strong oxidising agent. Under unfavourable conditions, oxy- gen can cause spontaneous combustion of organic substances such as particles, oils and fats, and generally promotes the combustion of substances.
