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.
Special attention has been given to hygiene and cleaning requirements in the construction of the pump. The number of grooves and dead spaces have been limited to an absolute minimum. Furthermore, no liquid can enter between the lobes and shafts. The Hyduty and Hyclean rotary lobe pumps by INOXPA have been approved by the American 3A Standard Authorities.
The field of application for each type of pump is limited. The pump was selected for certain pumping conditions at the time that the order was passed. INOXPA assumes no responsibility for damages that may arise in the event that the information made available by the purchaser is incomplete (nature of the liquid, viscosity, r.p.m.
- Lip seal INOXPA: maximum pressure 7 bar materials: VITON - Gland packing: maximum pressure 10 bar materials: PTFE SAFETY VALVE. The positive displacement lobe pumps must be protected from excess pressure when they are operating. Consequently, all the Hyclean and Hyduty pumps can be fitted with a stainless steel safety valve or a safety by-pass.
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 SLR 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.
Piping Installation Piping can be installed horizontally and vertically, provided that the pump remains leveled. 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.
DIRECTION OF ROTATION. The direction of rotation determines the location of the pump's suction and discharge mouths. The standard rotation direction is clockwise looking from the rear end of the motor, displacing the fluid from right to left (see figure 4.4). However, it is easy to invert the rotating direction and therefore vary the fluid's flow direction.

Self-priming process. In general terms --if the self-priming process is followed-- the pump ought to contain sufficient liquid to fill the internal recesses and the void spaces thus enabling the pump to create a pressure difference. However, if low viscosity fluids are to be pumped, a foot valve of the same or greater diameter as that of the suction pipe should be installed;...
If the seal requires flush media, the media supply and the purchase and installation of piping, valves ... for the media are not the responsibility of INOXPA. The flush shaft seal option (F) is available on all seal types. Use the sectional drawings of the SLR seal options in chapter 9 to purchase additional parts.
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.
When checking the safety valve also make sure the pump's pressure will NEVER exceed the pressure setting + 2 bar. When the safety valve does not work properly, the pump must be taken out of service immediately. The valve must be inspected by an INOXPA service technician. Figure 5.1: Safety valve ED. 2010/11...

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.
PREPARATIONS. Work area. Provide for a clean work area; some parts require very careful handling and others are machined to close tolerances. Tools. Use tools which are designed for the purpose for which they are to be used in maintenance and repair work. Use them properly. Disconnection.
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 wing nuts (45). Grooves are provided on 4 places along the circumference to permit removing the pump cover with the aid of, say , a screwdriver, if need be.
MECHANICAL SEAL AND SHAFT SLEEVE. Mechanical seal, G • One time the pump cover (09) has been disassembled, as indicated in the foregoing section, take out the seal cover (09A) - the stationary part of the mechanical seal (08A) comes out of the pump cover -. Measures have been taken to avoid that this face could rotate simultaneously with the shaft.
Slightly grease the shaft sleeve local to the O-ring before assembly of the seal cartridges. Seal with lip seal INOXPA, M. • During disassembly of the cartridge (support 0: 09E; support 1, 2, 3, 4 and 5: 09), -see instructions above- the lip seal M has already come out off the outer pump housing.
