Installation and Operating Manual Series MNKA-B, acc. to ASME/ANSI 2.1 For the customer/operator 2.4 The following must be observed: The notes on safety contained in this operating manual, the prevailing regulations on accident prevention, in-house work, operating and safety regulations of the customer. Hot or cold machine parts must be protected by the customer against being touched. No protective facilities may be removed when the machine is in operation. Hazards due to electricity are to be excluded.
Installation and Operating Manual Series MNKA-B, acc. to ASME/ANSI Overloading, overheating, non-observance of the design data or the incorrect selection of the magnetic drive can lead to the decoupling of the inner and outer magnet assemblies. As a result, eddy currents are induced on the inner and outer magnet assemblies and an inadmissible rise in temperature may occur. The situation is to be remedied by providing appropriate monitoring facilities. See Section 5.6.
Installation and Operating Manual Series MNKA-B, acc. to ASME/ANSI The following Table 1 contains the resultant theoretical limit values of the temperature of the liquid medium allowing for the temperature classes according to European EN 13463-1. Table 1 Temperature class acc.
Installation and Operating Manual Series MNKA-B, acc. to ASME/ANSI If the unit is not installed immediately after delivery, it must be put into proper storage. It should be stored in a dry, vibration-free room as at constant a temperature as possible. If magnetic drives are stored as single parts, the relevant notes in Section 7.5.2 are to be observed. In the case of prolonged storage conservation agents on machined component surfaces and packing with a desiccant may be necessary.
Installation and Operating Manual Series MNKA-B, acc. to ASME/ANSI 5.4 Piping 5.4.2 Nozzle loads Before the pump is installed, both the suction and supply lines as well as the discharge line are to be cleaned. Dirt or damage to the sealing surfaces is best avoided if the flange covers remain on the flanges until just before installation. Use flange gaskets suitable for the medium. The screw tightening torques in Section 1.2 are to be observed for tightening the flange screws. 5.4.
Installation and Operating Manual Series MNKA-B, acc. to ASME/ANSI 5.5 Pipe fittings 5.7 The following pipe fittings are available from Richter on request: Shut-off valves Check valves Sight glasses Priming vessels Strainers Pressure gauges Fig. 5 5.6 Monitoring facilities Appropriate monitoring facilities are to be recommended, depending on the requirements placed on operational safety and availability of the unit.
Installation and Operating Manual Series MNKA-B, acc. to ASME/ANSI 6 Commissioning/Shutdown 6.1 Initial commissioning Normally, the pumps have already been test-run with water. Unless special agreements have been made, there could still be residual amounts of water in the pump. This must be noted in view of a possible reaction with the medium. 6.1.
Installation and Operating Manual Series MNKA-B, acc. to ASME/ANSI If the pump has been operated with a chargeable liquid, it must be filled with inert gas (e.g. nitrogen) to prevent an explosive atmosphere. It is recommended to wait one hour before the pump is dismantled from the plant to permit static peak charges to be eliminated. These measures are not necessary with pumps with a conductive plastic lining. If the pump is returned to the manufacturer's, clean the pump very thoroughly. See also Section 3.
Installation and Operating Manual Series MNKA-B, acc. to ASME/ANSI 7.4 Stand-by pumps If a pump is on stand-by, it is to be started up from time to time. Regularly turn the shaft by hand in the direction of rotation. This operation is to be performed more often for pumps which are exposed to very strong vibrations from the plant. When dismantling the pump from the plant, drain it, thoroughly clean it, seal with flange covers and store in accordance with the instructions.

Pull out hollow drive shaft 216. 7.6.3 Dismantling the slide-in unit If the bearing pedestal has not been dismantled: Caution ! Magnetic forces ! Risk of accident ! Axial forces are produced when the plain bearing pedestal 339 is pulled out of the lantern 344. They diminish again abruptly after it has been removed.

If this is not possible, cool can (containment shell) insert to approx. 41 °F (5 °C). Place intermediate ring 509/1 in the bearing pedestal 330. Insert the entire unit into the lantern 344. 7.8.
Installation and Operating Manual Series MNKA-B, acc. to ASME/ANSI 8 Faults Faults may result from inadmissible modes of operation. Such inadmissible modes of operation – even brief ones – may cause serious damage to the unit. In connection with explosion protection, potential sources of ignition (overheating, electrostatic and induced charges, mechanical and electric sparks) can result from these inadmissible modes of operation; their occurrence can only be prevented by adhering to the intended use.

Safety Information / Declaration of No Objection Concerning the Contamination of Richter-Pumps, -Valves and Components 1 SCOPE AND PURPOSE Each entrepreneur (operator) carries the responsibility for the health and safety of his employees. This extends also to the personnel, who implements repairs with the operator or with the contractor. Enclosed declaration is for the information of the contractor concerning the possible contamination of the pumps, valves and component sent in for repair.
Declaration about the Contamination of Richter Pumps, -Valves and Components The repair and/or maintenance of pumps, valves and components can only be implemented if a completely filled out declaration is available. If this is not the case, delay of the work will occur. If this declaration is not attached to the devices, which have to be repaired, the transmission can be rejected. Every aggregate has to have it’s own declaration.
