Functional description Functional description 5.1 Pump The metering pump is an oscillating diaphragm pump, the stroke length of which is adjustable. An electric motor drives the pump. 5.2 Liquid end The diaphragm (2) hermetically shuts off the pump volume of the dosing head (4) towards the outside.
Functional description P_SI_0019 Fig. 8: Integral relief valve Spring, large Ball Rotary dial Spring, small Hose connection 5.4 Multi-layer safety diaphragm With visual diaphragm rupture sensors, in the event of a diaphragm rup‐ ture, the lowered red cylinder (6) springs forward beneath the transparent cover (7) so that it then becomes clearly visible - see Fig.
Assembly Assembly Compare the dimensions on the dimensional drawing with those of the pump. 6.1 Assembly of the motor - with designs without motor Select a suitable motor. The motor must correspond to the data for one of the motors from the "Motor data" table - see Chapter "Tech‐ nical Data".
Assembly Model size Motor flange B 5/140 * (26) Dimensions in mm - unless otherwise indicated. * Motor is fitted directly onto the motor flange without intermediate flange and claw coupling. 6.2 Base The pump can break through the base or slide off it Ensure that the base is horizontal, flat and permanently load-bearing.
Assembly 6.4 Fastening Liquid end alignment Dosing rate too low. The valves of the liquid end cannot close correctly if the valves of the liquid end are not upright. Ensure that the discharge valve is upright. Vibrations can disturb the liquid end valves. Secure the metering pump so that no vibrations can occur.

Installation, hydraulic CAUTION! Danger due to incorrect use of the integral relief valve The integral relief valve can only protect the motor and the gear, and then only against impermissible positive pressure that is caused by the metering pump itself. It cannot protect the system against positive pressure.
Installation, hydraulic 7.1 Basic installation notes Safety information Rupturing hydraulic components Hydraulic components can rupture if the maximum permissible oper‐ ating pressure of the hydraulic parts is exceeded. Never allow the metering pump to run against a closed shut-off device. With metering pumps without integral relief valve: Install a relief valve in the pressure line.
Never change the “Motor voltage” and “Cycle frequency” parameters with motor designs with integral frequency converter. The parameters on delivery from ProMinent do not correspond to the motor manufacturer’s factory settings. If other parameters are to be changed, then we recommend speaking to...

Start up Using the integral relief valve CAUTION! Danger due to incorrect use of the integral relief valve The integral relief valve can only protect the motor and the gear, and then only against impermissible positive pressure that is caused by the metering pump itself. It cannot protect the system against positive pressure.

Start up Auxiliary equipment Check for the correct function of the auxiliary equipment and for correct interplay.
During operation During operation WARNING! Personnel injury and material damage may occur During use all units, protective equipment, additional devices must be fitted, operational and tightly closed. WARNING! Sparking caused by dry running If the bearings in the power end run dry, sparks can be formed.
Maintenance Maintenance 11.1 Safety information ATEX pumps in areas at risk from explosion Carry out a general check to ensure that the system is working prop‐ erly, particularly the power end and bearings, by regular monitoring (for leaks, noises, temperatures, smell ...). Do not allow the pump to run hot due to a lack of oil.
WARNING! In the area at risk from explosion: Stop the pump safely and as quickly as possible and rectify these anomalies. ProMinent Service may be needed if required. 11.3 Standard liquid ends Under heavy loading (e.g. continuous operation) shorter maintenance intervals are recommended than those given.

Should this not work, remove dirt or swarf from the thread and screw the diaphragm correctly onto the drive axle this time. ð If this is still unsuccessful, contact ProMinent-ProMaqua Service. Place the dosing head with the screws onto the diaphragm - the suction connector should be pointing downwards when the pump is subsequently installed.
