Services

Summary of consulting services offered:

Objective, independent engineering consulting services specializing in rotodynamic (centrifugal, mixed flow and axial flow) pumping equipment.

Evaluation of essential pump selection parameters including overall mechanical configuration and arrangement, staging, drive train and driver type, rotative speed, net positive suction head, nozzle orientation, materials of construction, shafting, thrust compensation, couplings, bearings, seals, etc.

Evaluation of pump and system performance including:

  • system total head versus rate of flow
  • head versus flow (H-Q) curve slope
  • H-Q stability of single and multiple pump operation
  • pump minimum flow
  • viscous effects
  • effects of wear and parasitic losses
  • input power
