Selection data we need from you

  • Flow rate (m3/h or LPM) and total head (m)
  • Liquid name, temperature, viscosity, solids percentage
  • Suction conditions and available NPSH
  • Material requirement (cast iron, SS304, SS316, duplex, alloy, rubber lined)
  • Seal type requirement (packing, mechanical seal, double seal, flush plan)
  • Motor supply (kW, voltage, Hz) and area classification if any
  • Installation location and pipe size restrictions
  • Operation hours per day and starting frequency

Materials and compliance

AreaWhat we check
Hydraulic performancePump curve, efficiency, NPSHr, allowable operating range
MaterialsCasing, impeller, shaft, wear parts, elastomers matched to liquid
SealingSeal plan suitability, flushing requirement, leakage control
TestingHydro test, performance test report as per agreed standard
PackagingRust protection, wooden crate, spare parts labeling

Recommended critical spares

  • Mechanical seal kit or packing set
  • Bearing set
  • Impeller and wear ring (if applicable)
  • Shaft sleeve
  • Gaskets and O rings
  • Coupling insert or spacer (if used)

For high uptime sites, we suggest keeping at least one seal kit and bearing set per critical pump in stock.
