When the noise level in the operating area exceeds 85 dB(A), a special protection shall be installed. APPLICATION. The main advantage of the INOXPA lobe pump is its capacity to pump a great variety of viscous liquids, from 1 mPa.s up to 100.000 mPa.s Furthermore, it is capable of pumping liquid products that require very careful handling and liquids that contain soft solids thys causing only a minimum degradation of same.
When the pump is used in a pumping unit or in an environment for which the pump has not been designed, the operator and the material may be exposed to hazard. Consult INOXPA in case of doubt prior to use.
- Single mechanical seal: 2500 mPa.s (Newtonian liquid) The maximum viscosity allowed will depend on the nature of the liquid and the sliding speed of the seal faces. Consult INOXPA should the viscosity be still greater. SAFETY VALVE. The positive displacement lobes pumps must be protected from excess pressure when they are operating.
4. Installation. GENERAL CONSIDERATIONS. This manual provides basic instructions which should be taken into account when proceeding to install the pump. It is of utmost importance that the plant foreman reads this manual before installation. The instructions include pertinent information which will enable you to install your pump / pumping unit correctly. The manual also contains important instructions for preventing eventual accidents and serious damage which could occur prior to start up and during the installation.
Outdoor installation. The TLS pump can only be installed out of doors if there is a roof covering it or, if permitted, a special installation is to be made. Consult INOXPA prior to installation. Indoor installation. Place the pump so that the motor is properly ventilated. Prepare the motor to be started according to the instructions provided by its manufacturer.
HANDLING. If the pump is supplied without a drive, the purchaser/user is responsible for the pump's start-up and assembly. Starting torque. The starting torque of the positive displacement pumps is almost identical to the rated torque. Make sure that the motor's rated torque is sufficiently high, but check that it does not exceed the maximum torque allowed on the pump shaft (see technical specifications).
Connection. Consult the supplier's instructions prior to connecting the motor to the power supply. For single-phase motors, use motors with an increased starting torque. Ensure a starting torque which is sufficiently high for motors controlled by a frequency converter, and provide for adequate cooling at low speeds.

Suction pipe. Liquids should be introduced into the pump from a higher level than that of the pump; the pipe should be inclined in its path to the pump and be devoid of air pockets. A diameter which is too small, a suction pipe which is too long, or a filter that is too small or clogged, will lead to a greater loss of head and thus the NPSH available (NPSHa) can become less than that required (NPSHr).
Page 16
Shut-off valves. For a proper maintenance, the pump should be isolated. This isolation can be obtained by installing shut-off valves in the suction and discharge pipes of the pump. These valves should be able to open completely, both for suction and for discharge, up to the full passage of suction and discharge pipes (ball-valves or sluice valves are preferable).
5. Start-Up. GENERAL CONSIDERATIONS. The pump can be started up so long as the instructions given in chapter 4 ("Installation") have been followed. Prior to start-up, the persons responsible for the operation must be duly informed of the pump / pumping unit's operation and the safety instructions.
SAFETY VALVE. The safety valve opening pressure setting is done in the INOXPA workshop. However, the valve's opening pressure depends on the fluid to be pumped, its viscosity, its r.p.m.., and so before starting-up the pump, the operator ought to adjust the safety valve's opening pressure.
Make sure that the personnel read the entire instruction manual and, in particular, indicate to them the chapters which refer to work which needs to be done. INOXPA does not assume responsibility for accidents and damage which might occur as a result of any failure to comply with the instructions indicated herein.
ELECTRICAL INSTALLATION. Maintenance work on electrical installations can only be done by qualified personnel and only when the power supply has been cut off. Carefully follow national safety regulations. Also abide by the regulations referred to above if you are working while the power supply is still connected. Check to see whether the electrical materials to be cleaned are well protected (for example, IP 54 indicates protection against dust and water spray but does not include protection against pressure water jets).
Incorrect assembly or disassembly may cause damage in the pump's operation and lead to high repair costs and a long period of down-time. INOXPA is not responsible for accidents or damages caused by a failure to comply with the instructions in this manual.
DISASSEMBLY AND ASSEMBLY. PUMP HOUSING. • Close the suction and discharge valves. ATTENTION! The liquid can spill out when the pump housing is removed. • Remove the Allen screws (51). • Check to see that the O-ring (80A), located in the pump cover (09), is still in good condition. •...
• Check if the shaft sleeve (13A) is in good condition. To disassembly the shaft sleeve see the instructions above. • Slightly grease the sleeves local to the lip seal element before assembly of the lip seal cover. Seal with INOXPA lip seal, M. • Disassembly the pump cover (09) and the seal cover (09A).
ADJUSTING THE LOBES To adjust the lobes, the lantern unit and the geared motor must be removed from the support. For this purpose, the housing, the lobes, the pump cover and the seals must be disassembled first, as indicated in the relevant section. •...

10. Cleaning and Disinfection. GENERAL CONSIDERATIONS. Cleaning and disinfection of the installations is necessary and mandatory on completing any manufacturing process in the food industry. The use of an installation which is NOT cleaned or disinfected can cause contamination of the products. The cleaning cycles as well as the chemical products and procedures used will vary depending on the product and the manufacturing process.
SAFETY IN CLEANING AND DISINFECTION. Manual cleaning. • Disconnect the motor starting system before cleaning the pump. • Provide cleaning personnel with the most appropriate protective equipment -clothing, footwear, safety glasses. • Do not use toxic or inflammable solvents for cleaning the pump. •...
