Series MNK-B, close-coupled design 2 Page 5 Notes on safety This operating manual contains fundamental information which is to be observed during installation, operation and maintenance. It must be read before installation and commissioning! This operating manual must always be available at the place of use of the machine/plant. In addition to the general notes on safety under the main heading “Safety”, special notes on safety are included at other points and must be observed.
Series MNK-B, close-coupled design The instructions contained in the operating manual or contract documentation must be observed; if necessary consult the manufacturer. All important features are documented in the data sheet included in the scope of delivery. In the event of operating conditions other than those described in the data sheet, the following are to be checked again: design of the pump design of the accessories resistance of the materials. 2.
Series MNK-B, close-coupled design 2.6.2 Special operating conditions In the standard design the can chamber and the plain bearings are cooled and lubricated by a flushing flow. Owing to properties of the medium (e.g. sticking due to inadmissible solids entrainment, clogging, gas entrainment etc.) the cooling flow can be interrupted and, as a result, an inadmissible temperature rise may occur. Provide appropriate monitoring facilities. See Section 5.6. For safe pump operation, we recommend a flow rate of 0.
Series MNK-B, close-coupled design Page 8 2.6.7 Temperature limits The following always applies: No inadmissible temperatures may be introduced into the motor and the specifications of the motor manufacturer must be observed.
Series MNK-B, close-coupled design Page 9 2.6.8 Maintenance 2.6.9 Electric peripheral equipment For safe and reliable operation, it must be ensured with regular inspection intervals that the unit is properly serviced and kept in a perfect technical condition. If auxiliary systems (e.g. external flushing, cooling, heating) are installed, a check must be made to see whether monitoring facilities are required to safeguard their operation. Electric peripheral equipment, e.g.
Series MNK-B, close-coupled design 4 Product description The housing dimensions, nominal ratings and technical requirements of the pump series MNK-B correspond to ISO 2858 / DIN EN 22858 / ISO 15783 / DIN ISO 5199. The technical requirements of the VDMA 24279 are satisfied. The sectional drawing shows the design of the pump. See Section 9. All components which come into contact with the medium are either plastic-lined or made of other resistant materials, e.g. silicon carbide.
Series MNK-B, close-coupled design Page 11 5.4.1 Nominal size The operating design point of a centrifugal pump lies at the intersection of the pump curve and the pipe curve, see Fig. 2. The pump curve is provided by the pump manufacturer. The pipe curve is determined using diagrams or PC programs. Fig. 3 5.4.4 Supply lines Fig.2 Under no circumstances can the nominal size of the piping be derived from the connected nominal size of the pump.
Series MNK-B, close-coupled design Page 12 5.7 Drive The power consumption of the pump at the operating design point is specified in the data sheet and works certificate. If the operating design point was not known when the pump was dispatched, the power consumption can be read off the appropriate performance curves. The max. density, the max. viscosity and a safety margin are to be allowed for. Care must be taken when selecting the motor size to ensure that the excess power is not too great.
Series MNK-B, close-coupled design 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. 6.1.1 Filling the pump housing Check to see whether the screws on the suction flange, discharge flange, housing flange and drain flange are tightened.
Series MNK-B, close-coupled design 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 3.1. 6.4 Restarting When the pump is restarted, it must be ensured that all the relative steps as described in Section 6.1 are repeated, depending on the progress of the shutdown operation.
Series MNK-B, close-coupled design 7.4 Stand-by pumps If a pump is on stand-by, it is to be started up from time to time. 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. 7.
Series MNK-B, close-coupled design Make sure that no parts of the plain bearing fall. Silicon carbide is easy to break. Keep bearing sleeves 529 and bearing bushes 545 in pairs which belong together. Clamp pump shaft 211 with the flat pivot point in a vice. Use smooth clamping jaws. Undo impeller 230 or inner magnet assembly 859 (depending on which part has remained on the pump shaft).
Series MNK-B, close-coupled design Push on bearing sleeve 529/2 on the rotor side and install these units in the plain bearing pedestal 339. Only push bearing sleeve 529/1 on the impeller side partially onto the pump shaft 211. Put impeller 230 onto the pump shaft 211. Permit the anti-torsion cams of the impeller side bearing sleeve 529/1 to engage in the grooves of the impeller. Screw on impeller together with bearing sleeve and tighten. 7.8.3 Determine thicknesses S1 and S2 of the distance washers 551.
Series MNK-B, close-coupled design 8 Page 18 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. See also Section 6.5.

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.
