Tube selection: The chemical compatibility lists published in Watson-Marlow pub- lications are guides. If in doubt about the compatibility of a tube material and the duty fluid, request a Watson-Marlow tube sample card for immersion trials. 4.3 Troubleshooting 114DV, 114DVP If the pump runs but there is little or no flow, make the following checks: Check that the tube is in the pumphead. -
Page 7: Pumphead Mounting
Allen-key headed M4 screws, length equal to 5mm + the thickness of the mount. Tighten them to a maximum of 0.5Nm. Drive shafts 8mm in diameter are recommended, but shafts from 6mm diameter to 10mm diameter are acceptable. Watson-Marlow Alitea 114 pumpheads: operating instructions... -

Factors affecting torque requirement Bioprene More torque +Pressure occlusion Low temperature High temperature Standard occlusion Less torque Pumpsil Watson-Marlow Alitea 114 pumpheads: operating instructions... -
Page 9: Tube Holder Positioning
The inner setting will clamp the tube harder, reducing tube slip but has the potential to marginally reduce flow rate. The outer setting will optimise flow rate but the risk of tube slip is increased. Watson-Marlow Alitea 114 pumpheads: operating instructions... -
Page 10: Tube Holder Repositioning
Note: The pictures on the previous page show the tube holders’ correct positions for small and large tubing. If a tube holder is not vertical relative to the body of the pumphead, it is wrongly positioned. Follow the instructions above to reposition it.

Page 11: Tube Loading
The tube must not be twisted or stretched against the rollers. Lower the flip top until it clicks into its fully closed position. The track closes automatically and the tube is stretched correctly as it does so. Watson-Marlow Alitea 114 pumpheads: operating instructions... -
Page 12: Flow Rates And Pressure Capabilities
Reduce the flow rates quoted by 10% if using Pumpsil tubing. Recommended tubing 114DV: Bioprene, Marprene, Pumpsil, STA-PURE PCS and STA-PURE PFL 114DV (formerly CHEM-SURE). 114DVP: Bioprene, Marprene, Pumpsil, STA-PURE PCS, STA-PURE PFL 114DVP (formerly CHEM-SURE), PVC and Neoprene.
