Page 3: Safety
1. Safety 1.1 General This Operation & Maintenance Manual contains basic information to be noted during installation, operation and maintenance. It is therefore essential that the Manual is read by the contractor before installing and commissioning the pump/system as well as by the relevant operating personnel / owner of the pump/system. -
Page 4: Qualification And Training Of Personnel
1.3 Qualification and training of personnel The personnel employed for installation, operation, inspection and maintenance must be qualified for this work. The areas of responsibility, competence and supervision of the personnel must be precisely defined by the owner. Personnel who do not have the required knowledge must be duly trained and instructed. -
Page 5: Unauthorized Modification And Production Of Spare Parts
The dosing pump may only be modified or converted in consultation with the manufacturer. Genuine spare parts and accessories authorized by the manufacturer ensure greater safety. Liability for damage or loss may be voided if non Lutz-Jesco parts are used. - Page 6 CAUTION! • Chemical could spray out. This may lead to caustic or other burns. Always relieve the system/pump pressure before starting work on the dosing pump. • Before working on the dosing head, check valves and connections, flush the pump’s CAUTION! wetted end with a harmless medium (mainly water) to avoid unintentional contact with the metered medium.

Page 10: Performance Curves
The performance curves refer to water at 20 °C (68 °F). The performance of the dosing pump depends on the viscosity of the process fluid and hydraulic installation conditions. Dosing pumps must therefore be gauged in litres during application. MAGDOS LC 2 10 bar 145 psig... -
Page 11: Installation
7. Installation 7.1 General notes of instruction For the selection of a dosing pump when designing a system as well as for the installation and operation, local rules and regulations must be obeyed. This applies to the selection of appropriate materials of construction, the handling of the chemicals and the electrical installation. -

avoided. If the dosing pump is installed outside, provide a roof to protect it against weather. 7.3 Electrical connection DANGER! • Fire hazard. Pressure surge: parts may burst and cause fatal injury. DANGER! Magdos LC must never be used in an explosion-proof area. The electrical connection of the dosing pump must be made according to the local rules and regulations and may only be carried out by technical personnel. -

Page 15: Setting Of Flow Rate
8.1 Setting of flow rate Volumetric displacement per dosing stroke The stroke length adjustment limits the movement of the diaphragm. Adjusting the stroke length does not have a linear proportional effect on the stroke volume. The volume per dosing stroke is shown in the performance curves or displayed on the dosing pump’s calibration table. -

Page 17: Maintenance
11. Maintenance Dosing pumps are produced according to the highest quality standards and have a long service life. Nevertheless some parts are subject to wear caused by operation (e.g. diaphragm, valve seats, valve balls). To ensure a long operating life, visual inspection is recommended regularly. - Page 18 Replacing the diaphragm 1. Remove the dosing head with a suitable tool (size 3 Allen key). Figure 1 2. With the dosing pump operating, adjust stroke length setting to 0% and then turn pump off. Insert the locking pin (Art. No.
- Page 19 5. Grease the diaphragm rod with Molykote DX at the contact point with the housing bushing and along the diaphragm thread. 6. Push the support plate onto the threaded connector of the new diaphragm with the concave side facing towards the diaphragm. Figure 4 7.

11.4 Drive solenoid DANGER! Components are energized! Electric shocks can kill! Unplug the mains connector before opening the pump. DANGER! CAUTION! Hot metal parts may burn your hands. Always disconnect the mains power supply before opening the magnetic drive and let the dosing pump cool down for at least one hour. -
Page 24: Correction Of Stroke Length Adjustment
11.5 Correction of stroke length adjustment IMPORTANT! After replacing the diaphragm or other spare parts it might become necessary to readjust the dosing pump. IMPORTANT! Legend Stroke length adjusting knob Locking screw 1. Switch power on. 2. Regardless of the indicator position, loosen the locking screw and turn the stroke length adjusting knob counterclockwise until the dosing pump no longer delivers or, in the case of pressureless operation, only delivers minimum. -
