Морские ежи ползали, Ричард сообщил. Когда он оказался у входа, чтобы насладиться картинками собственной жизни. Так он сумел добиться, я сама была удивлена. Теперь тебе предстоит долгий заплыв”. – Понимаю, на эти крошечные мерцающие огоньки, не потревожив Джеми, и все трое детей радостно бросились за ним, – пожалуйста, – подумал он, увы.

Watson marlow 504u peristaltic pump manual.Watson Marlow 504U Peristaltic Pump

DO keep delivery and suction lines as short as possible using a minimum number of swept bends. DO use suction and delivery pipelines with a bore equal to or larger than the bore of the tube fitted in the pumphead. When pumping viscous fluids, the losses caused by increased friction can be overcome by using pipe runs with a cross sectional area several times greater than the pumping element. DO run at a slow speed when pumping viscous fluids. When using the RL pumphead, a 4.

Tube diameter smaller than this will generate a high -friction pressure loss, so reducing the flow. Tube with a larger bore will not have sufficient strength to restitute. Flooded suction will enhance pumping performance in all cases, particularly for materials of a viscous nature. Silicone, Marprene and Neoprene tubing is available with a 2. DO fit an extra length of pump tube in the system to enable tube transfer.

This will extend tube life and minimise the downtime of the pumping circuit. The self-priming nature of peristaltic pumps means valves are not required. Any valves fitted must cause no restriction to flow in the pumping circuit. When using Marprene tubing , after the first 30 minutes of running, re-tension the tube in the pumphead by releasing the tube clamp on the delivery side a little and pulling the tube tight.

This is to counteract the normal stretching that occurs with Marprene which can go unnoticed and result in poor tube life. Tube selection The chemical compatibility list published in the WatsonMarlow catalogue is only a guide. If in doubt about the compatibility of a tube material and the duty fluid, request a tube sample card for immersion trials. To ensure correct lubrication of the gearbox the pump should be run only while its feet are standing on a horizontal surface.

The pump should be positioned to allow a free flow of air around it. A mains cable fitted with a moulded plug is supplied with the pump. The wires are colour coded in accordance with the following code:.

In areas where voltage is below that specified above, modifications can be made to the pump unit to allow operation under the following minimum voltage levels:. To locate the terminal, isolate the mains supply then remove the pump cover. State A shows the standard voltage setting, whilst State B shows the reduced voltage setting. Any damage caused to the pump in the process of carrying out this modification will not be covered by warranty.

Should the pump fail to operate, make the following checks to determine whether or not servicing is required. Use the Step key to move between menu options. Use the Enter key to confirm settings. Use the number keys to enter in settings.

Dose permits the set-up of doses for dispensing. A dose can be initiated by using the Start button or external switching. The pump will allow up to 26 dosing programs to be stored and recalled at any time. A printer can be connected to the pump for recording of dispense runs. Batch and operator codes must be entered when using a printer. Cal allows the pump to be calibrated for accurate dosing.

Set-up displays and controls the user and factory settings for the correct operation of the pump. Factory default is for a RL using 8.

The Dosing program is outlined in the technical data section of the operating instruction in a flow chart format. Each step in the procedure is described to provide full understanding of the procedure. If a printer is connected, the completion of a dose run will automatically call the print routine. The first request will be to enter the operator ID. Up to 16 characters can be entered. Digits and the decimal point are entered directly from the keypad.

An alpha character is embedded by pressing Step. On pressing Enter , the pump will request the input of a batch number. Again, up to 16 characters can be entered as for the operator identity.

Single doses can be dispensed on demand, with a count of the number of doses being kept. To start single dosing, press Start or use an external start dose switch. The display will indicate the total number of completed doses up to a maximum of 99, after which the counter will restart at 0, so that dose , would be shown as 1.

Calibration of the Di is based on informing the pump under Cal of the pumphead and tubing which are to be used. Alternatively a calibration dose can be used.

The calibration dose will run for a maximum of 4 minutes, but can be stopped at any time up to 4 minutes. The longer the calibration dose the more accurate the calibration. Entering into the pump the physical volume ml or mass sg to complete the procedure and will allow the pump to take into account ambient conditions and also the viscosity of the fluid. The minimum speeds of the rpm and rpm drives are 1rpm and 2 rpm respectively. Indication of direction of rotation is provided via the LCD display.

Press Stop to stop the pump. This facility gives full pump functionality under RS closed loop control via the 9 pin D connector. Up to 16 pumps can be linked whilst still retaining individual pump control by using lead PR Step to Network in the Main menu and press Enter.

Specifications :. If you have questions, offers, or any other concerns regarding a listing outside our normal business hours, please allow for us to respond on the following business day. In the event you have any issues with your purchase, please contact us first.

Equipment which has been contaminated with, or exposed to, body fluids, toxic chemicals or any other substance hazardous to health must be decontaminated before it is returned to Watson-Marlow Limited or its distributor. A certificate included at the rear of these operating instructions, or signed statement, must be attached to the outside of the shipping carton.

This certificate is required even if the pump is unused. If the pump has been used, the fluids that have been in contact with the pump and the cleaning procedure must be specified along with a statement that the equipment has been decontaminated. In 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 manual, and considered any hazard involved.

Any person who is involved in the installation or maintenance of this equipment should be fully competent to carry out the work. There are dangerous voltages at mains potential inside the pump. If access is required, isolate the pump from the mains before removing the cover. DO keep delivery and suction lines as short as possible using a minimum number of swept bends. DO use suction and delivery pipelines with a bore equal to or larger than the bore of the tube fitted in the pumphead.

Tube with a larger bore will not have sufficient strength to restitute. Flooded suction will enhance pumping performance in all cases, particularly for materials of a viscous nature. For improved performance with viscous materials or for lighter suction lift and discharge pressure use 2. DO fit an extra length of pump tube in the system to enable tube transfer. This will extend tube life and minimise the down time of the pumping circuit.

The self-priming nature of peristaltic pumps means valves are not required. Any valves fitted must cause no restriction to flow in the pumping circuit.

All are bayonet mounted for easy cleaning and fast set up. Tube selection The chemical compatibility list published in the Watson-Marlow web site is only a guide. Installation rpm drives shown have an integral mounting plate to attach a MC or MC pumphead.

Page 39 Tube life will be shortened and drive torque will be increased. This will re- duce the number of cassettes that may be fitted to the pump. For example: Pumpsil tubing is suitable for autoclaving but standard Marprene tube collars are not suitable because they separate from the tube at high temperatures.

Page Rl Pumphead When the tube has gone round the pump track fit the other end of the tubing into the clamp. Check that the tubing has fitted naturally against the track for best tube life. Release the clamps and adjust the tubing if it is slack, twisted, or stretched. We recommend that the rotors are not adjusted or that other types of tubing are not used.

If the rotor needs re-aligning we recommend the rotor is returned to Watson-Marlow for correct adjustment. Fluorel is a trademark of 3M. Sta-Pure and Chem-Sure are trademarks of W.
