1 Industrial Pumps fficiency and Reliability

2 Loctite echnologies for Industrial Pum Most industrial pumps carry a significant capital value and therefore it is important to extend their useful lives and ensure that they run efficiently and reliably. Loctite technologies have been helping OMs around the world prevent common failures and extend end-product life. he same technologies are used by maintenance people in all stages: assembly, installation, repairs, on-going maintenance, and disassembly. Proactive Maintenance can reduce the risk of breakdowns, increase pump reliability, efficiency and longevity, and extend the MBF (Mean ime Between Failures). Prevent fretting and corrosion while securing bearings with Loctite 641 Retaining Compound Make any size gasket with Loctite 518 Flange Sealant Prevent rust and seizure of power end bolts with Loctite Marine Grade nti-seize Prevent Key wallow with Loctite 243 Medium Strength hreadlocker or repair key wallow with Loctite 660 Quick Metal Retaining Compound Prevent set screws from working loose with Loctite 222 hreadlocker or Loctite 243 hreadlocker Secure and prevent leakage between oil seals and housing with Loctite 243 Medium Strength hreadlocker or Loctite 248 Medium Strength hreadlocker Sticker Seal threaded fittings with Loctite 567 PS hread Sealant with PF Keep mounting bolts tight with Loctite 271 High Strength hreadlocker

3 ps Rebuild and Maintenance Goulds 3196 pump was used to demonstrate Loctite solutions to common failures and challenges. Similar solutions will apply to other types and brands of industrial pumps. he environments in which these pumps operate, not necessarily pump construction, can affect pump operation and efficiency and present challenges to end users. here are more Loctite solutions available than depicted below. Please contact Loctite to discuss your specific application needs. Protect pump against chemical attack and errosion with Loctite Nordbak Chemical Resistant Coatings Rebuild and protect worn volutes with Loctite Nordbak Wearing Compound and/or Loctite Nordbak Brushable Ceramic Restore, coat and protect impeller vanes with Loctite Nordbak Brushable Ceramic Prevent corrosion and seizure of gland assembly nuts and seizure of the impeller to the shaft with Loctite Marine Grade nti-seize Rebuild worn shafts with Loctite Fixmaster Superior Metal Seal and protect flushing connectors with Loctite 567 PS hread Sealant with PF Prevent corrosion and secure casing bolts and adapter bolts with Loctite 243 Medium Strength hreadlocker Provide a solid mounting base with Loctite Fixmaster Super Grout

4 Loctite echnologies - Improve Industrial Pumps fficiency and Reliability Loctite technologies have improved efficiency and reliability of industrial pumps, new and old. he following test shows that after coated by Loctite Nordbak Brushable Ceramic, Pump fficiency increased by +4.8% from 82.4% to 87.2%, ot. Head increased by +4% from 29.5 mtr to mtr, Power Input reduced from kw to kw. *Q=200 l/sec Original Pump Curve nd Suction Pump usgpm igpm MXIMUM POWR kw SPD: 1475 R.P.M % 50% 60% % INL DI.: 250 mm 76% 35 DISCH DI.: 200 mm O % 32.5 No. 4 SHF MODUL 82% L H 82% % 22.5 D % 20 IMPLLR DI. - mm 70% ~ % M R 10 50% 55 kw S kw 8 37 kw NPSHR NPSHR 274mm 6 342mm 4 metres O L 90 H D 60 ~ 50 F 40 l/sec m³/hr VOLUMRIC FLOWR D FOR CLN COLD WR ONLY PUMP PRFORMNC O S2417 GRD 2 PUMP MODL CURV No. SHJ x D ISSU 2 Pump Curve after Coated by Loctite Nordbak otal H ead 25 -m P U M P S N o:22k S O U H R N C R O S S 250X m m 1475rpm D :23/11/ % S2417 Grade P um p ffic. 70 -% kw 50 P um p Input 80 Power -kw Flow rate -l/se c Pump fficiency est Data Pump Make: SOUHRN CROSS Pump Size: 250X Pump Serial No.: 22K Duty Flow Required (l/s): 200 Duty Head Required (m): 29.5 Duty fficiency Req'd (%): 82.4 Pump ype: ISO PRO Impeller Dia.

5 Loctite Maintenance Workshop - what you need to improve pump efficiency and reliability By applying the identified product solutions and techniques learned in Loctite Maintenance Workshop, your personnel will have the knowledge and the tools to rebuild and maintain your pumps to improved efficiency and reliability. Please call Loctite today to schedule a workshop tailored for you! he majority of unplanned downtime is caused by mechanical subcomponent failure. Some taproots reasons are: fastener loosening, key wallow, PF tape fouling control valves, fitting leakage and spun bearings. his workshop teaches how to prevent these from happening proactively.
