PumpsaverBraided ConnectorsFeatures and BenefitsFlex-Hose Co.’s PUMPSAVER connectors are metal flexibleconnectors available instainless steel or bronze.They are used to preventdamage to pumps caused bypiping stress. PUMPSAVER connectors also absorbvibration and noise found inpump installations.PUMPSAVER connectors areeasily installed and reducethe possibility of pumpfailure.They are designed to be pressuretested 1.5 times their maximumrated working pressure andmanufactured with a 4:1 safetyfactor. Their compact design savesvaluable space.Working pressure of standard hoseand braid up to 1325PSI or fullvacuum and operating temperaturesof -400°F to +1500°F.PUMPSAVERS are manufacturedwith 321 stainless steel or bronzeannular corrugated close pitchmetal flexible hose.PUMPSAVERS are available withflanged ends, steel male NPTends, grooved ends, weld ends, orcopper tube female sweat ends andmay include multiple braids forhigher working pressures.TMQuality Assurance...Precision ManufacturingFlex-Hose Co.’s PUMPSAVER manufacturing process incorporatesthe removal of the first convolution lipat the crest creating a smooth transition.This eliminates internal sharp edgesor burrs which may break offduring operation, thus causing damageto pumps and precision rotating equipment.PUMPSAVERS design andmanufacturing utilizes state-of-the-artwelding technology.Flex-Hose Co. has welderscertified to ASME Section IX.Stock sizes 1/2” to 14” I.D.Additional sizes and custom styles available.Please consult factory.Three year fullreplacement warranty.Refer to warrantyregistration for details.• WARRANTY •PUMPSAVERS are pressuretested for manufacturing integrityprior to release for shipment.23

ENGINEERING BULLETIN“Right Combination” reduces pump vibrationIf you’re reading this information, itis likely that at some time you’ve beeninvolved in specifying, installing, orproviding solutions designed to reducevibration in mechanical piping systems.Mechanical room pumps,chillers, cooling towers, fans, and boilersgenerate vibration and noise.Sound, or noise, is the result of a vibrationin an elastic medium. Even in thebest designed systems, there is no feasibleway to avoid all noise and vibration...they are simply inherent in theprocess. A pump, for example, deliversa continuous stream of pulses to thefluid as the impeller blades pass thecutoff in their housing.Referring to the 1995 ASHRAEApplications Handbook (Chapter 43 -Sound & Vibration Control, pg.43.34/.39/.40)... All piping systemshave mechanical vibration generatedby the equipment which is transmittedby the pipe wall and the water column.Flexible pipe connectors (1) providepiping flexibility to permit isolatorsto function properly, (2) protectequipment from strain (stress) due tomisalignment, and (3) attenuate noiseand vibration transmission along thepiping. All flexible connectors requireend restraint to counteract the pressurethrust. Metal hose is constructedwith a corrugated inner core andbraided cover that helps attain a pressurerating and provides endrestraints that eliminate the need forsupplemental control assemblies.Although there are numerous proposalsfor resolving vibration problemsinherent to mechanical pipingsystems, each having its own merits,the following proposal will specificallyaddress an efficient and cost-effectivesolution using braided metal pumpconnectors. The information presentedrepresents a collective effort byspecifying engineers, HVAC mechanicalcontractors, representatives/distributorsof pump manufacturers andHVAC mechanical equipment, and aleading manufacturer of braided metalpump connectors (Flex-Hose Co., Inc.).The 1996 ASHRAE Systems andEquipment Handbook (Ch. 38 -Centrifugal Pumps) depicts a typicalbaseplate mounted centrifugal pumpshutoff valveTYP>Option Asuction diffuser▼▼▼▼Figure 1 - Centrifugal Pump Installationinstallation.
