Series RMI-B close-coupled design 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-B close-coupled design 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.
Series RMI-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 Chapter 5.6. For safe pump operation, we recommend a flow rate of 0.
Series RMI-B close-coupled design Page 8 Table 2 2.6.7 Temperature limits In the normal operating condition the highest temperatures are to be expected 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. heating jacket), it must be ensured that the temperature classes prescribed in the annex are observed.
Series RMI-B close-coupled design 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-B close-coupled design 4 Page 10 Product description The housing dimensions, nominal ratings and technical requirements of the pump series RMI-B correspond to 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 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-B close-coupled design Page 11 5 Installation 5.1 Safety regulations 5.4.1 Nominal size 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.
Series RMI-B close-coupled design Page 12 5.4.3 Suction line 5.5 The suction lines must always be laid on a rising gradient towards the pump. Otherwise, gas bubbles may form which considerably reduce the suction line cross section. Eccentric transition elements must be installed between different pipe diameters. Valves which disrupt the course of flow should not be installed directly upstream of the pump.
Series RMI-B close-coupled design 5.7 Drive 5.8 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.
Series RMI-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 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. 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 RMI-B close-coupled design 6.3 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. Page 15 position The plain bearing in the pump may be destroyed. Other pump components may be destroyed due to overheating.
Series RMI-B close-coupled design 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 suction flange discharge flange draining flange See also Chapter 6.1.1, para. 1. Other inspections are to be performed regularly, depending on the operating requirements.
Series RMI-B close-coupled design 7.6 Dismantling There are two possibilities for dismantling: 1. Dismantling the complete pump from the plant. 2. Dismantling the complete slide-in unit as the pump housing can remain in the plant connected to the piping. Dismantling of the complete pump is described here. Undo support bracket from the base plate. The adapter and support bracket are one part in group 1.2, motor sizes 80, 90, 100 and 112. With the adapters of the groups 1.1, 1.2 motor size 132 and 1.
Series RMI-B close-coupled design 7.7 Notes on assembly Page 18 7.7.1 Table for target dimension Z 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.
Series RMI-B close-coupled design 7.8 Assembly A complete assembly process is described in the following. Sub-sections can be deduced from this. 7.8.1 Assembly of housing / shaft spider Push or press the shaft spider 338 into the housing 100 together with the two anti-torsion inserts 566/1. Use a suitable plastic tube for pressing. The pressing force must only be applied over the sliding surface of the shaft spider.
Series RMI-B close-coupled design Motors acc. NEMA-standard: After setting the “F” dimension, use a 1/4” drill bit to drill 2 holes 1/16” deep where the set screws contact the motor shaft and key. This will ensure there is no movement of the outer drive during operation.Possibly it is necessary to machine the key of the motor shaft by drilling bit new. See sectional drawing in Chapter 9.2.
Series RMI-B close-coupled design 8 Page 21 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.
