Series MNKA, acc. to ASME 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. Observe the safety notes in all the chapters. Installation, operation and maintenance are to be performed by qualified staff.
Series MNKA, acc. to ASME 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 suitability of the materials. 2.2 For the customer/operator 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.
Series MNKA, acc. to ASME For safe pump operation, we recommend a flow rate of 0.3 to 1.1 Qopt. If the pump is operated outside this range, it must be ensured that the max. admissible flow rate according to the pump characteristic curve is not exceeded and that the max. admissible operating temperature according to Section 2.6.
Series MNKA, acc. to ASME Page 8 During operation of the pump it must be ensured that excessive deposits of dust are prevented (regular cleaning) in order to prevent the pump surface from heating to above the admissible temperature. 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.
Series MNKA, acc. to ASME 3 Page 9 Transport and storage 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 MNKA, acc. to ASME 4 Page 10 Product description The housing (casing) dimensions, nominal ratings and technical requirements of the pump series MNKA correspond to ASME B73.3M, ISO 15783 / DIN ISO 5199. 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. The housing (casing) 100 consists of a metallic shell with a plastic lining.
Series MNKA, acc. to ASME Page 11 A distance depending on the coupling used is to be observed between the pump and motor shafts. See installation drawing. Use supports in the direct vicinity of the bolts foundation/base plate. Ensure that the unit cannot be started during work without the coupling guard. 5.4 Piping Before the pump is installed, both the suction and supply lines as well as the discharge line are to be cleaned.
Series MNKA, acc. to ASME Page 12 5.4.6 Venting and draining 5.6 Venting can take place into the discharge line or upstream of the discharge valve. A venting line can also be used as a bypass, drain or flushing line. The pump housing (casing) is fitted with a drain connection as a standard feature. Optionally, the drain bore can be drilled. See Figure 4. Appropriate monitoring facilities are to be recommended, depending on the requirements placed on operational safety and availability of the unit.
Series MNKA, acc. to ASME 5.8 Coupling If one coupling half engages with the other, the claw section is normally to be mounted on the pump shaft and the coupling half with the smooth end face on the motor shaft. Observe the operating manual of the coupling manufacturer. A coupling with a valid ATEX certificate is to be used if deployed in zone 1 and 2. Regulations exist, e.g. for the following details: Arrangement of the coupling halves Page 13 5.
Series MNKA, acc. to ASME 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. Grease for life lubrication The rolling bearings are greased for life. Regreasing is not possible and not necessary. For service lives, see Section 7.2.
Series MNKA, acc. to ASME 6.3 Shutdown Close discharge valve down to the position "minimum flow rate" Switch motor off. Close discharge valve completely. Only close the suction line if the pump is to be evacuated or dismantled. For all work on the machine, make sure that the motor cannot be inadvertently switched on. If the pump is to be evacuated or flushed, observe the local regulations. If the pump has been operated with a chargeable liquid, it must be filled with inert gas (e.g.
Series MNKA, acc. to ASME 7 Maintenance 7.1 Screw connections of the housing (casing) Page 16 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 (casing) flange suction flange discharge flange See also Section 6.1.1, para. 1. 7.2 Bearing pedestal The temperature of the bearing pedestal is not to exceed more than 122 °F (50 °C) and under no circumstances 176 °F (80 °C).
Series MNKA, acc. to ASME 7.5 Notes on dismantling Page 17 7.6 Dismantling All repair and maintenance work is to be performed by skilled staff using appropriate tools and original spare parts. Is the necessary documentation available? There are 3 possibilities for dismantling: 1. Remove the complete pump from the plant. 2. Remove the complete slide-in unit, i.e. the housing (casing) remains in the plant. Has the pump been taken out of operation, evacuated and flushed correctly? See also Section 6.3.
Series MNKA, acc. to ASME Both radial ball bearings lie against the shaft collar, so remove them singly on a press. Remove support bracket 183 (with bearing pedestal group 2). 7.6.3 Dismantling the bearing pedestal, oil bath lubrication Remove hex. screw 901/4 and drain oil. Clamp the end of the drive shaft 213 in a vice. Use protective jaws. Undo hex. socket screw 914/1 counterclockwise. Pull off drive magnet assembly 858. Remove pump from the vice.
Series MNKA, acc. to ASME 7.8 Assembly 7.8.1 Assembly of the bearing pedestal, long life grease lubrication Press both radial ball bearings 321/1 und 321/2 onto the drive shaft 213. Insert key 940/1 into the drive shaft. Install pre-assembled drive shaft into the bearing pedestal 330 from the motor side. Insert wavy spring washer 953/1 into the bearing pedestal 330. Mount rear bearing cover 361 with hex. socket screws 914/2. Mount support bracket 183 (with group 2) with hex.
Series MNKA, acc. to ASME Page 20 7.8.7 Final assembly Dismantle trial assembly for determining the bearing play again and perform the final assembly. With the O-ring 412/3 With the distance ring 504 With 1 drop of adhesive on the shaft thread, e.g. Loctite 243 from Loctite or an equivalent. Only one drop of the adhesive is to be applied per thread. Otherwise the next dismantling operation will be more difficult or no longer possible without destroying components.
Series MNKA, acc. to ASME 8 Page 21 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.
