Do keep delivery and suction tubes as short and direct as possible though ideally not shorter than 1m and follow the straightest route Use bends of large radius at least four times the tubing diameter Ensure that connecting pipework and fittings are suitably rated to handle the predicted pipeline pressure Avoid pipe reducers and lengths of smaller bore tubing than the pumphead section particularly in pipelines on the suction side Any valves in the pipeline not usually needed with a self prim ing peristaltic pump must not restrict the flow Any valves in the flow line must be open when the pump is running Do use suction and delivery pipes egual to or larger than the bore of the tube in the pumphead When pumping viscous fluids use pipe runs with a bore several times larger than the pump tube Do ensure that on longer tube runs at least 1m of smooth bore flexible tubing is con nected to the inlet and discharge port of the pumphead to help to minimise impulse losses and pulsation in the pipeline This is especially important with viscous fluids and when Connecting to rigid pipework Do site the pump at or just below the level of the fluid to be pumped if possible This will ensure flooded suction and maximum pumping efficiency Do keep the pumphead track and all moving parts clean and free from contamina tion and debris Do run at slow speed when pumping viscous fluids When using the 520R pump head a 6 4mm or 4 8mm bore tube with
