Page 3: Safety Instructions
1. Safety instructions 1.1 General This operating manual contains basic instructions to be followed during installation, operation and main- tenance. It is therefore essential that the Operating Manual be read by the installation technician before installing and commissioning the pump/system, as well as by the relevant operating personnel/operating company of the unit. - Page 4 WARNING! To reduce the risk of injury, do not permit children to use this product unless they are closely supervised at all times. WARNING! Risk of electric shock. Connect the device only to a socket outlet with earthing contact protected by a ground fault circuit interrupter (GFCI).

Page 7: Use For Intended Purpose
Dosing pumps are used to add chemicals in precisely metered quantities in various processes. Its universal control system allows flexible use of MAGDOS DE/DX in all applications. The dosing rates range from 0.1 to 115 litres per hour. The precise metered quantities at different backpressures can be derived from Section 6 "Delivery Characteristic Curves". -

Page 10: Delivery Characteristic Curves
6. Delivery characteristic curves The delivery characteristic curves refer to water at 20 °C (68 °F). The delivery capacity depends on the medium (density and viscosity) and temperature. Dosing pumps must therefore be gauged in litres for the application. 4 bar 10 bar 6 bar 2 bar... -
Page 11: Installation
NOTE! The size of the lines used in connection with MAGDOS DE/DX 12 must be at least DN 6. DN 4 should only be used for short lines (up to 1 m) and low-viscosity media (<20 mPa s) . -
Page 12: Water Meter Installation
NOTE! The dosing pump must be plugged into a grounded power outlet. The 230 V version of the MAGDOS DE/DX is connected by a shockproof earthing-pin plug. The 115 V version is equipped with a UL/CSA connector. -
Page 13: Pressure Control And Pressure Relief Valves
7.6 Pressure control and pressure relief valves Pressure control valves are used to optimise the dosing process. They are used • to increase the dosing accuracy in the case of fluctuating backpressure. • when the dosing lines are long, in order to prevent excess delivery, since the accelerated medium continues moving due to its own inertia even after the delivery stroke has ended. -

External mode is activated by turning to the left-hand stop (beyond the detent). A dosing stroke is executed for every incoming pulse in external mode. IMPORTANT! Pulses are not saved when the dosing pump is driven at more than the maximum pulse rate (see Technical Data).

Page 19: Start-Up
9. Start-up CAUTION! Personal protective equipment as specified by the applicable accident prevention regulations must be worn during all work on the dosing pump/system! Protective clothing Protective gloves Protective goggles 1. For initial start-up, set the pump to internal operation at 100% stroke frequency and allow the pump to prime. -
Page 20: Automatic Venting
9.1.1 Automatic venting ② ④ ③ ① ⑤ The automatic venting facility (standard features on DE/DX 03, 07 otherwise optional extra) consists of a non-return ball valve. The ball ③ rolls against the seat during the suction stroke and away from it during the pressure stroke. -
Page 21: Shutdown
10. Shutdown Before starting any maintenance work or before long downtimes, drain the chemicals from the dosing pump and rinse it thoroughly with a neutral medium. CAUTION! Excess chemicals must be disposed of properly. Observe the applicable accident prevention regulations and wear personal protective equipment. -

Chemical may spray out. This may lead to chemical or other burns. The dosing pump must always be depressurised and rinsed with water or a suitable medium before starting any work on the dosing pump. - Page 23 NOTE! Check that the deflector plate ⑤ is in perfect condition (Section 11.2 "Checking and replacing deflector"). 5.
