Series RMI 2 Page 5 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. Observe the safety notes in all the chapters. Installation, operation and maintenance are to be performed by qualified staff.
Series RMI Page 6 Observe the instructions contained in the operating manual or contractual documentation; 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 Observe the points listed in Chapter 6.1 prior to recommissioning. design of the accessories resistance of the materials. 2.
Series RMI 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 also Chapter 5.6. For safe pump operation, we recommend a flow rate of 0.3 to 1.1 Qopt.
Series RMI Page 8 2.6.7 Temperature limits 2.6.8 Maintenance In the normal operating condition the highest temperatures are to be expected at the contact point shaft seal/shaft, on the inner races of the ball bearings and, at high medium temperatures, on the surface of the pump housing. In the case of liquids >40 °C the surface temperature of the pump housing is generally lower than the temperature of the liquid as the plastic lining has an insulating effect. If the pump is heated (e.g.
Series RMI 3 Page 9 Transport, storage and disposal The pump or the unit must be transported properly. It must be ensured that during transport the pump/unit remains in the horizontal position and does not slip out of the transport suspension points. A pump or motor can be suspended from the ring bolt provided for this purpose. The suspension points are not suitable for transporting a complete unit, i.e. pump with base plate and motor.
Series RMI 4 Page 10 Product description The housing dimensions, nominal ratings and technical requirements of the pump series RMI correspond to ISO 2858 / DIN EN 22858 / ISO 15783 / DIN ISO 5199. The technical requirements of the VDMA 24279 are satisfied. The sectional drawings show the design of the pump. See Chapter 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 RMI 5 Installation 5.1 Safety regulations Equipment which is operated in potentially explosive areas must satisfy the explosion protection regulations. People with a pacemaker are at risk from the strong magnetic field of the magnetic drive. It may be life-threatening for them to stay at a distance of less than 20” (500 mm) to the pump. 5.2 Installation of pump/unit The structural work must be prepared in accordance with the dimensions in the installation drawing.
Series RMI Page 12 The NPSHR available in the plant should be at least 1,64 ft (0,5 m) higher than the NPSHR required for the pump. Otherwise, this will lead to a drop in the delivery head, cavitation or even failure of the pump. 5.4.2 Nozzle loads The pump can be subjected to nozzle loads in accordance with DIN EN ISO 5199. See also TIS-No. 0541-02-0006. Changes in the length of the piping caused by temperature are to be allowed for by appropriate measures, e.g. the installation of expansion joints. 5.
Series RMI 5.6 Monitoring facilities Appropriate monitoring facilities are to be recommended, depending on the requirements placed on operational safety and availability of the unit. Richter provides information on request and can supply: Flow meters Filling level indicators Motor load monitors You can obtain the publications "Safe Operation of Magnetic Drive Pumps" and "The Operation of Centrifugal Pumps without NPSH Problems" on request. 5.
Series RMI 6 Commissioning/Shutdown 6.1 Initial commissioning Normally, the pumps have already been test-run with water. Unless special agreements have been reached, there may still be some residual amounts of water in the pump. This must be noted in view of a possible reaction with the medium. Long life grease lubrication The ball bearings are greased for life. Regreasing is not possible and not necessary. For service lives, see Chapter 7.2.
Series RMI 6.3 Page 15 Pump is started up without medium : Shutdown Close discharge valve down to the "minimum flow rate" Switch motor off. Close discharge valve completely. Only close the suction line if the pump evacuated or dismantled. For all work on the machine, make the motor cannot be inadvertently on. position The plain bearing in the pump may be destroyed. Other pump components may be destroyed due to overheating.
Series RMI Page 16 7 Maintenance 7.1 Safety-relevant screw fittings After initial loading by the operating pressure and operating temperature the tightening torques of all connection screws must be checked at the following points: housing flange discharge flange draining flange See also Chapter 6.1.1, point 1. Other inspections are to be performed regularly, depending on the operating requirements.
Series RMI 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. Page 17 Hold magnetic drives as single parts firmly or secure.
Series RMI 7.6.2 Dismantling of drive unit long life grease lubrication Undo hex. socket screw 914/5 with toothed lock washer 936/1. Remove drive magnet assembly 858. If necessary, use a pulling-off device. Undo screws 914/6 of the rear bearing cover 361. Remove rear bearing cover 361 and wavy spring washer 953/1. Press drive shaft 213 with the two ball bearings 321/1 and 321/2 out of the bearing pedestal 330 in the direction of the motor. 7.6.3 Dismantling of drive unit oil bath lubrication Undo hex.
Series RMI 7.7 Page 19 Notes on assembly Use original spare parts. See also Chapter 2.4. Do not use defective parts. Apply Anti-Seize special assembly paste (e.g. from Weicon) to the fitting surfaces (not any stainless steel surfaces) and screw thread prior to assembly. Check whether all parts fit and only then assemble. Important dimensions (centerings, bearing fits or bearing play) are to be checked prior to assembly; perform a trial assembly if required.
Series RMI Page 20 Press the bearing bush 545/1 into the impeller 230 together with the anti-torsion insert 566/2. Make sure that the anti-torsion insert 566/2 is approx. 2 mm shorter than the plain bearing. Insert distance ring 504/1 and then the bearing bush 545/2. Carefully press the thrust ring 510/2 into the impeller 230 right to the stop. When doing so, pay attention to the correct position of the anti-torsion insert grooves in relation to the carrier webs in the impeller 230.
Series RMI 7.8.5 Final assembly Deposit the housing 100 on a workbench, for example, with the suction nozzle facing downwards. In doing so, protect the plastic sealing strip against damage with a suitable base. Insert housing gasket 401 into the centering of the housing 100. Mount pre-assembled slide-in unit concentrically onto the shaft spider 338. Pres outer wear ring 502/1 into the housing 100. Insert pre-assembled can unit. The lip of the can insert 158 must rest on the housing gasket 401. Page 21 7.
Series RMI 8 Page 22 Malfunctions Faults may result from inadmissible modes of operation. Improper operation, even for brief periods, may result in 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 Chapter 6.5.
