  • Page 7: General Information

    3.3. APPLICATION The main advantage of the INOXPA HLR rotary 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 thus causing only a minimum degradation of same.
  • Page 8 The range of application for each type of pump is limited. The pump was selected for a given set of pumping conditions when the order was placed. INOXPA shall not be liable for any damage resulting from the incompleteness of the information provided by the purchaser (nature of the fluid, rpm, etc.).

  • Page 9: Installation

    Serial number Pump plate 4.2. TRANSPORT AND STORAGE HLR pumps and pumping units are often too heavy to be handled manually. Use an adequate means of transport. Use the points which are indicated in the drawing for lifting the pump.
  • Page 10 • When the grout has entirely hardened the pump unit can be placed on the base plate or the frame. Tighten the nuts on the foundation bolts carefully. For other foundations consult INOXPA. 4.4. COUPLING For the couplings selection and assembly consult to the supplier manual. Sometimes the torque of the positive displacement pumps can be high enough.

The flush shaft seal option is available on all seal types. Use the sectional drawings of the HLR seal options to purchase additional parts.

  • Page 13: Pressure Relief Valve

    4.7. PRESSURE RELIEF VALVE The positive displacement lobe pumps must be protected from excess pressure when they are operating. Consequently, all the HLR pumps can be fitted with a stainless steel pressure relief valve or a pressure by-pass 4.7.1. Protection This valve protects the pump and prevents excessively high pressure arising in the circuit.

  • Page 14: Pressure By-Pass

    The end user must adjust the valve to the correct pressure. When an overflow valve or a pressure bypass does not operate properly, the pump must immediately be removed from service for repair. The valve must be examined by the INOXPA technical assistance personnel. (A) 2021/11 5.Start-up...
  • Page 15 When checking the relief valve also make sure the pump's pressure will NEVER exceed the pressure setting + 2 bar. When the relief valve does not work properly, the pump must be taken out of service immediately. The valve must be inspected by an INOXPA service technician. 5.Start-up (A) 2021/11...

Always use protective goggles. 7.3.2. Automatic CIP (cleaning-in-place) If the pump is installed in a system fitted with a CIP process, there will be no need for stripping. The recommended minimum liquid speed for an effective process of cleaning is 1,8 m/s (minimum Re >...
