1-rEEDER Global Dosing System Design and Innovation Installation and operating instructions YOUR LEADER IN DOSING TECHNOLOGY

MXD pumps are heavy duty, precision, electric diaphragm positive displacement pumps. This dosing pump consists of one main gearbox with dosing head. This unit forms the main drive of the dosing pump. What makes the MXD pump special is the capability to add as many extras dosing units to the drive unit. This allows volumes from 10 liters per hour up to any volume imaginable. Each of these dosing units can be independently regulated by means of a positive adjustment caliper. Dosing units can be designed in such a manner that several different volumes or products can be dosed or the total...

Functional principle 5.1 GENERAL To install this pump it is advisable to choose places protected from water, away from heat sources and air renewal. Place the pump vertically over a rigid surface to achieve proper distribution of lubrication. Anticipate spaces needed for maintenance and installation. The electric protection of the motor must be installed and adjusted following its nominal instensity (overloaded switch disjuntor). (See wiring). Reciprocating displacement pump with electric motor and mechanical diaphragm control. • The rotation of the motor is transformed into the...

8.3 SUCTION It is essential to fit in the suction of the dosing liquid the filter of 500 mesh. Couple the suction pipe to the lower connecter of the cylinder, putting the mesh filter inbetween. The sediment at the bottom of the tank must never be suctioned, to avoid suction of undiluted parts. The piping must be stiff enough so that it does not lose its shape when there is suction. To help suction the piping must be as short as possible, the pipe diameter must be at least 40 mm. For pipes of over 3 m, diameter must be increased. 8.4 INJECTION Fix the check valve supplied with the pump at the...

OIL: Take off re-filling lid and fill the pump with the provided oil: 320 GRADED OIL. If the pump has several boxes oil must be filled into all boxes. Approximate oil capacity: When carrying, keep upright. Warning When dosing dangerous media, observe the corresponding safety precautions! Risk of chemical burns! CHECKING THE HYDRAULIC CIRCUIT: Check that all valves are opened and that escapes from priming valves derive the liquid to a proper receptacle. Wear protective clothing (gloves and goggles when working on the dosing head, connections or lines! Do not allow any chemicals to leak from the...

11. Fault finding chart Fault 1. Dosing pump does not run. a) Not connected to the power supply. Connect the power supply cable. b) Incorrect supply voltage. Replace the dosing pump. Return the pump for repair. d) The empty indication has responded. e) The diaphragm leakage detection has responded. 2. Dosing pump does not suck in. a) Leaking suction line. Replace or seal the suction line. b) Cross-section of the suction line too small or suction line too long. Check with I-Feeder specification. c) Clogged suction line. Rinse or replace the suction line. d) Foot valve covered by sediment. S...

The dosing curves on the following pages are trend curves. They apply to: • performance of simple pump (the flow rate is doubled for the double pump) water as dosing medium suction line with foot valve, 0.5 m flooded suction zero point of pump Q 0 for specified pressure, see table below standard pump version. Zero point of the pump The pumps are calibrated so that Q is 0 at 2 bar. Stroke length
