Check that the lubricant level is above the minimum level line in the inspection window. If necessary add Bredel Genuine Hose Lubricant via the breather/vent plug.

  • Page 33: Commissioning

    COMMISSIONING Commissioning Connect the pipework. Make sure that there are no obstructions such as closed valves. Switch on the hose pump. Check the rotation direction of the pump rotor. Check the capacity of the hose pump. If the capacity differs from your specification, follow the instructions in chapter or consult your Bredel representative.

  • Page 34: Operation

    OPERATION OPERATION Temperature The pump will heat up during normal operation. Heat is generated in the contact zone between the pressing shoe and the hose. The heat is removed by the lubricant and transported to the pump casing and cover. Under conditions of high pressure and running speed, casing and cover temperatures can reach values of over 65 °C (+149 °F).

  • Page 37: Dry Running

    OPERATION Dry running Dry running is a running condition of the pump when no process flow (pumped product) is flowing through the pump. The Bredel peristaltic pumps are very suitable for dry running. Dry running does impose an additional thermal load on the pump hose, because the internal heat associated with repetitive hose compression is normally removed by convection of the process fluid.

  • Page 38: Fluid Leakage

    OPERATION Genuine Hose Lubricant is harmless (FDA approved), but it will result in additional downtime since the pump needs to be cleaned prior to new hose installation. WARNING Exceptions to this general rule are when the pumped product is either a strong oxi- dizer or a strong acid.
  • Page 39 OPERATION Both the pumphead and gearbox are directly coupled to each other. A special feature is included in the pumphead to enable early detection of seal damage of the pump or gearbox. This feature is called the leakage zone. When a seal starts to show increased leakage, this can be detected at the back side of the pump.

  • Page 40: Maintenance

    MAINTENANCE MAINTENANCE General WARNING Make sure that during maintenance the power supply is disconnected. CAUTION Only use original Bredel parts when main- taining the hose pump. Bredel cannot guarantee a correct functioning pump and any consequential damage that occurs from the use of non-original Bredel compo- nents.

  • Page 41: Maintenance And Periodic Inspections

    MAINTENANCE WARNING If the cover is removed when the pump hose is still in the pumphead, the compres- sion forces on the pump hose may cause deformation of the pump housing. The hose needs to be safely removed before the cover can be replaced. Normally the compression forces are par- tially compensated by the cover.

  • Page 47: Cleaning The Pump Head

    MAINTENANCE 8.6.2 Cleaning the pump head WARNING Never remove the cover when the pump hose is in the pumphead. The compression forces on the pump hose are partially compensated by the cover. By removing the cover with the hose installed, subsequent damage can occur.

  • Page 48: Fitting The Pump Hose

    MAINTENANCE Check the pressing shoes for wear or damage and replace them if necessary. See § 8.7.2. Also see the maintenance scheme in § 8.2. CAUTION When the pressing shoes are worn the compression force of the hose decreases. If the compression force is too low, this results in a loss of capacity by the backflow of the liquid to be pumped.
  • Page 49 MAINTENANCE Fit the pump hose (A) via one of the ports – whichever is the suction based on rotation direction. Feed the hose into the port and allow the pressing shoe to draw the hose in the pump housing. The rotor will move the hose. Stop the motor when the hose sticks out equally from both sides of the pump housing.
  • Page 50 MAINTENANCE Turn the rotor in such a way that the hose (A) is pressed firmly against the flange surface (B). Now fully tighten the retaining bolts (A) of the flange bracket (B). Make sure the bolts are tightened with the correct torque. See § 11.1.6. Position hose clamp (A) against O-ring chamber of the flange bracket (B) and fasten the retaining bolt.
