This certificate is requiredeven if the pump is unused. See 27 Decontamination certificate.If the pump has been used, the fluids that have been in contact with the pump andthe cleaning procedure must be specified along with a statement that the equipmenthas been decontaminated.E, S, U, Du 6 Peristaltic pumps - an overviewPeristaltic pumps are the simplest pump, with no valves, seals or glands to clog orcorrode. The fluid contacts only the bore of a tube, eliminating the risk of the pumpcontaminating the fluid, or the fluid contaminating the pump. Peristaltic pumps canrun dry.How they workA compressible tube is squeezed between a roller and a track on an arc of a circle,creating a seal at the point of contact. As the roller advances along the tube, the sealalso advances. After the roller has passed, the tube returns to its original shape, cre-ating a partial vacuum which is filled by fluid drawn from the inlet port.Before the roller reaches the end of the track, a second roller compresses the tubeat the start of the track, isolating a packet of fluid between the compression points.As the first roller leaves the track, the second continues to advance, expelling thepacket of fluid through the pump’s discharge port. At the same time, a new partialvacuum is created behind the second roller into which more fluid is drawn from theinlet port.Backflow and siphoning do not occur, and the pump effectively seals the tube whenit is inactive. No valves are needed.The principle may be demonstrated by squeezing a soft tube between thumb and fin-ger and sliding it along: fluid is expelled from one end of the tube while more is drawnin at the other.Animal digestive tracts function in a similar way.Suitable applicationsPeristaltic pumping is ideal for most fluids, including viscous, shear-sensitive, corro-sive and abrasive fluids, and those containing suspended solids. They are especiallyuseful for pumping operations where hygiene is important.Peristaltic pumps operate on the positive displacement principle. They are particularlysuitable for metering, dosing and dispensing applications. Pumps are easy to install,simple to operate and inexpensive to maintain.E, S, U, Du7 Safety notesIn the interests of safety, this pump and the tubing selected should only be used by competent, suitably trained personnel after they have read and understood this man-ual, and considered any hazard involved.

In the UK this person should also be familiar with the Health and Safety at Work Act 1974.There is a user-replaceable type T1.0AH 250V fuse in the fuse drawer of the IEC mains connector atthe back of the pump, which also contains a spare fuse. In some countries, the mains power plugcontains an additional replaceable fuse. There are no user-ser-viceable fuses or parts inside this pump.There are moving parts inside the pumphead. Before opening the track, en-sure that the following safety directions are followed.Ensure that the pump is isolated from the mains power.Ensure that there is no pressure in the pipeline.If a tube failure has occurred, ensure that any fluid in the pumphead has been allowed to drain to a suitable vessel, container or drain.Ensure that protective clothing and eye protection are worn if hazardous fluids are pumped.Primary operator protection from rotating parts of the pump is provided by the pumphead track. See 23 Pumpheads.This product does not comply with the ATEX directiveand must not be used in explosive atmospheres.This pump must be used only for its intended purpose. The pump must be accessible at all times to facilitate operation and maintenance. Access points must not be ob-structed or blocked. The pump’s mains plug is the disconnecting device (for isolating the motor drive from the mains supply in an emergency). Do not position the pump so that it is difficult to disconnect the mains plug. Do not fit any devices to the drive unit other than those tested and approved by Watson-Marlow. Doing so could lead to injury to persons or damage to property for which no liability can be accepted.If hazardous fluids are to be pumped, safety procedures specific to the particular fluid and application must be put in place to protect against injury to persons.The exterior surfaces of the pump may get hot during operation. Do not take hold of the pump while it is running. Let it cool after use before handling it.No attempt should be made to run the drive without a pumphead fitted.E, S, U, Du8 Pump specificationsLabels fixed to the rear of the pump contain manufacturer and contact details,product reference number, serial number and model details.8.1 Pump features15-400 rpm3-400 rpmFour models of 323 drives are documented in this manual: 323E, 323S, 323U and 323Du, with varying functionality, as described earlier in this section. The 323E is fit-ted with a short-nosed gearbox, offers 15-400 rpm, and can be fitted with a 313 or 314 pumphead. The 323S, 323U and 323Du are available with a choice of gearboxes:a short-nosed gearbox, which offers 3-400 rpm and can be fitted with a 313 or 314pumphead, or a 314MC or a 318MC pumphead; and a long-nosed gearbox, which of-fers 1.5-220 rpm and can be fitted with a 501RL or a 501RL2 pumphead.

Site the pump on aflat, horizontal, rigid surface, free from excessive vibration. Allow a flow of air aroundthe pump to ensure that heat can be dissipated. Ensure that the temperature aroundthe pump does not exceed 40C.Emergency disconnectionThe pump’s mains plug is the disconnecting device (for isolating the motor drive fromthe mains supply in an emergency). Do not position the pump so that it isdifficult to disconnect the mains plug. The STOP key on the keypad will always stopthe pump. However, it is recommended that a suitable local emergency stop deviceis fitted into the mains supply to the pump.ValvesPeristaltic pumps are self-priming and self-sealing against backflow. No valves arerequired in inlet or discharge lines. Valves in the process flow must be opened beforethe pump operates. Users are advised to fit a pressure relief device between the pumpand any valve on the discharge side of the pump to protect against damage causedby accidental operation with the discharge valve closed.The pump may be set up so that the direction of rotor rotation is clockwise orcounter-clockwise, whichever is convenient.Tubing materials: run-in adviceSta-Pure and Marprene tubing are hard to compress when new. When usingtubing made of these materials, the first 30 seconds should be at a speed of 10 rpmor greater. If the pump is run slower, the safety system built into pump drive’s soft-ware may cause it to stop and display an over-current error message.9.2 Do’s and do not’sDo operate the pump on a flat horizontal surface. The pump requires a free flow of air for cooling. Do not block the air vents beneath the pump or at the rear.Do not stack pumps more than three high.Do use only single phase mains electricity supplies.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. When pumping viscous fluids use pipe runs with a bore several times larger than the pump tube. Any valves in the pipeline (not usually needed) must not restrict the flow. Any valves in the flow line must be open when the pump is running.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 minimize 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.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. Flooded suction will enhance pumping performance in all cases, particularly for materials of a viscous nature.Do recalibrate after changing pump tubes, fluid, or any connecting pipework. It is also recommended that the pump is recalibrated periodically to maintain accuracy. When using Marprene or Bioprene continuous tubing, do re-tension the tube after the first 30 minutes of running.Tube selection: The chemical compatibility lists published in Watson-Marlow publica-tions 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.We recommend using commercially available supplyvoltage surge suppression where there is excessive elec-trical noise.E, S, U, Du10 Connecting this product to a power supplyA well regulated electrical mains supply is required along with cable connections con-forming to the best practice of noise immunity. It is not recommended to site these drives alongside “dirty” electrical mains supplies such as 3-phase contactors and in-ductive heaters without special attention being paid to unacceptable mains-borne noise.The voltage selector is mounted in the switchplate at the rear of the pump. Set the voltage selector to 115V for 100-120V 50/60Hz supplies or 230V for 200-240V 50/60Hz supplies. Al-ways check the voltage selector switch before connecting the mains supply. Make suitable connection to an earthed, single-phase mains electricity supply. To comply with Safety Standards,the mains plug must be a separable plug (not a locking type).Input line fusing : type T1.0AH 250V 20mm time-delayed cartridge fuse, located in the combined mains IEC inlet socket and fuse drawer at the rear of the pump. Note: A spare fuse is also provided in the drawer .Conductor codingE, S, U, DuE, S, U, Du12 Switching the pump onSwitch on the power supply at the rear of the pump.
