Page 6: 2033 - 2063 M 3 /H Rotary Vane Pumps - Sd, C1, C2 Pascal Series
2033 - 2063 m /h rotary vane pumps. SD, C1, C2 Pascal series The 33 to 63m /h pump models, have following main characteristics: – A direct drive motor making them very compact. – An anti-suckback system ensures the tightness of the pump during accidental or voluntary shutdowns.
Page 7: Operating Principle Of The Rotary Vane Pump
Operating principle of the rotary vane pump Single-stage This is a volumetric pump, with a functional part composed of: • A hollow cylindrical stator with inlet and exhaust valves. rotary vane pump • A rotor mounted eccentrically inside the stator for pumping. •...
Page 8 Two-stage To improve the backing pressure and flowrate at low pressure, two stages are connected in series. The second is similar to the first both structurally and operationally. rotary vane pump The gases pulled in by the first stage (low pressure) are transferred to the second stage (high pressure) and discharged through the high pressure (HP) valve.
Page 9: Oil - Noise Limiter - Antisudback
Oil - Noise limiter - Antisuckback Oil has several important functions in the pump: – It lubricates mechanical components (bearings, seals, rotor, vanes, etc.). – It makes moving parts relatively tight by limiting internal leakage. – It carries away the heat produced by the compressed gases. Choosing the right oil Not all oils produce the same ultimate pressure in a given pump.
Page 10 Anti-noise Parallel to the oil flow, there is a small orifice in the venturi tube (5), which reduces the noise level at ultimate pressure. Because of the negative pressure created at the end of the venturi tube (5), gases are entrained into the moving layers of oil dampening pump noise, allowing the fluid to become more compressible.The added gases will affect the ultimate pressure, therefore, a compromise between sound level and ultimate pressure has to be reached as follows:...
Page 11 Gas ballast (cont’d) Using the gas ballast increases the ultimate pressure of the pump as well as the temperature. The gas ballast control, located on the frame cannot be used to set the gas injection flow rate. When the gas ballast control is open, the pump is not tight when stopped. To guarantee this tightness, install an automatic gas ballast.

It is the customer’s task to: - train operators to use the product if they do not speak the language the manual is written in, - ensure operators know the safe practices to apply when using the product.
Page 31: Before Starting Up The Pump
Operation (cont’d) Before starting-up the pump Check periodically that the pipes and accessories (i.e. oil mist eliminator) connected at exhaust are not clogged and that the purge is running. In certain cases, when the pump is started up in cold ambient conditions, or with slightly contaminated oil, the current after start-up may remain high until the oil in the pump is heated up.
Page 32: Operation Of Gas Ballast
Operation of gas ballast Regeneration of In a pump stored with the same oil for a long time, condensed vapors may contaminate the oil bath and affect performance. This is also the case after pumping vapors and pump oil when the oil appears cloudy or discolored through the sight glass. •...
Page 33 Pumping condensable vapors (cont’d) Vapor pumping procedure • Isolate the pump from the system and increase the pump temperature, 30 minutes with gas ballast (see page 31). • Start pumping and check the oil level: - The oil level drops, oil is being lost, add oil in the pump. - The oil level rises;...
Page 34: Purges For Pumping Condensable, Corrosive And Hazardous Gases
Purges for pumping condensable, corrosive, and hazardous gases C1 and C2 Series Purges The use of vane pumps may result in pumping gases or vapors which are flammable or that could contaminate the oil. In this case, these products must be diluted using purges supplied with dry gases, such as nitrogen to avoid undesirable reactions.

Page 36: Oxygen Pumping
Oxygen pumping In certain applications, mixtures containing oxygen at different concentrations, or even pure oxygen, are used. Oils of mineral origin are combustible. Exposure to pure oxygen at high temperatures may cause them to self-ignite. In addition, they are highly oxidized during pumping and quickly lose their lubricating properties.
Page 37: Recovery Of Oil (High Pressure Pumping And Cycling)
Recovery of oil (high pressure and cycling) When the pump operates at high pressure, the oil heats up, becomes more fluid and is flushed out of the functional block by the gas stream. Oil losses at the exhaust are increased. If the pump only operates for a very short time at high pressure, the lubricating oil For intermittent is replaced when the pump returns to low pressure.
Page 38: Safety Instructions For Maintenance
Safety instructions for maintenance General precautions For normal operation, the maintenance of 2033-2063 m /h series pumps only require regular oil changes (see page 41). Maintenance must be performed by a skilled maintenance operator trained in the relevant health and safety aspects (EMC, electrical hazards, chemical pollution, etc.).
Page 39: Troubleshooting And Corrective Actions

Page 44: Start-Up After Pump Disassembly Or Oil Change
Change of type of oil (cont’d) Incompatible oils This is the case when, for example, a mineral oil is replaced by a synthetic oil (e.g. A120 by A113). Synthetic oils are considered to be incompatible with each other for practical reasons: they are expensive.
