§ LEWA ecodos example Different Pump sizes are distinguished only by motor speed and therefore distinguished by n-pump and Q max. Example: Ecodos type 2 + 4, 6 + 12, 25 + 50, 90 + 180 e. g. 2 -pole motor makes from ecodos 6 one ecodos 12 Now customers ask for frequency operating motor and Q max. 12 l/h. Solution 1: 2 -pole motor 5 -50 Hz, mounting on ecodos 12 High motor power needed due to torque weakness for 2 -pole motors but also at higher price. Solution 2: 4 -pole motor 10 -100 Hz , mounting on ecodos 6 Now only half of motor power needed – BEST SOLUTION On data sheet Q 12 l/h at F/I-Operation with 100 Hz 17/03/2018 © LEWA Germany Slide 17

§ Principle of LEWA ecodos § This dosing pump combines all single functions of a dosing process: § Delivery: delivers the liquid and increases the pressure level § Measuring: displace of. . . . 2001 a given stroke volume with defined stroke frequency § Adjustment: stroke volume and - optional – stoke frequency are exact adjustable and variable 17/03/2018 © LEWA Germany Slide 18
