Metal Hose Pump Vibration Isolation Guide

Pump vibration can transfer cyclic stress into connected piping, equipment nozzles, supports, and building systems. Properly selected braided corrugated metal hose connectors can help decouple vibration and accommodate minor alignment variation when installed within the assembly’s validated pressure, temperature, bend, and movement limits.

Typical Pump and Equipment Applications

  • Hydronic pumps
  • Chilled-water pumps
  • Condenser-water pumps
  • Boiler and hot-water equipment
  • Data-center cooling pumps and CDUs
  • Packaged skids and heat exchangers
  • Industrial process equipment

Metal Hose Connector Selection Inputs

  • Nominal hose size
  • Required overall length
  • End Connection A and End Connection B
  • Hose and braid metallurgy
  • Single- or double-braid construction
  • Operating and design pressure
  • Operating and design temperature
  • Media / coolant
  • Expected vibration and movement
  • Minimum bend radius and installed geometry
  • Equipment nozzle load limits

Common Installation Problems

  • Installing the hose in torsion
  • Using the connector to pull misaligned piping into position
  • Insufficient live length
  • Operating below the validated bend radius
  • Unsupported connected piping transferring weight into the hose
  • Incorrect fixed/floating flange selection
  • Assuming flange class equals assembly working pressure

Connection Options

Pump and equipment connectors can use Class 150 or Class 300 flanges, threaded ends, grooved ends, weld ends, JIC connections, or mixed-end configurations where the application requires different End A and End B interfaces. Use the complete end-connection matrix for standard and RFQ-only pairings.

Engineering Tools

Connected piping still requires appropriate support and restraint based on the system design. Those conditions are engineering inputs to the hose selection; Flex Pipe USA’s current commercial catalog is focused on the metal hose connector itself.

Submit a Metal Hose RFQ with size, OAL, End A, End B, pressure, temperature, media, movement, quantity, and equipment drawings when available.
