Milton Roy Electromagnetic Diaphragm Metering PumpThe electromagnetic drive technology breaks the traditional structure of diaphragm metering pumps, which use electric motors as the prime mover and gears and crank connecting rods as the transmission mechanism. Instead, electronic control circuits are used to generate electromagnetic pulses, and the electromagnetic force of the energized solenoid coil is used to drive the plunger to make reciprocating linear motion. The flow rate is adjusted and controlled by the stroke rate. At present, the power of electromagnetic metering pumps is still very small, with a metering accuracy of 1%.

　　

　　Milton Roy Electromagnetic Diaphragm Metering Pumpworking principle

　　

The Milton Roy electromagnetic diaphragm metering pump reciprocates within the pump head, causing changes in the volume and pressure of the pump head chamber. The pressure changes cause the opening and closing of the suction and discharge valves, achieving quantitative suction and discharge of liquid.

　　

　　Milton Roy Electromagnetic Diaphragm Metering PumpThe rated displacement is within the range of 1-15L/H, corresponding to a maximum working pressure of 10-3BAR. The outlet flow rate of the pump can be adjusted according to the frequency button or stroke length adjustment screw. LED light emitting diode indicates the operating status

　　

　　Milton Roy Electromagnetic Diaphragm Metering PumpSafety precautions

　　

1Milton Roy Electromagnetic Diaphragm Metering PumpDo not use non original parts for maintenance, otherwise, the consequences of personal injury and machine damage caused by this shall be borne by the user;

　　

2. If the medium of the metering pump is a dangerous or unknown liquid, the operator should wear safety protective equipment when operating or repairing the metering pump;

　　

3. The metering pump needs to be tested before leaving the factory. There may be water residue in the pump head. If the medium of the metering pump cannot come into contact with water, the water must be removed before installation;

　　

4. When repairing the metering pump, the discharge pipe should be depressurized and the pump cavity should be cleaned with water;

　　

5Milton Roy Electromagnetic Diaphragm Metering PumpBefore maintenance, the power supply of the metering pump should be disconnected, and the electrical operation should be carried out by a qualified electrician;

　　

6. Only qualified personnel who have received training can repair the metering pump.
