According to US DOE, pumps are the second most widely used machines in the world, consume about 20% of the world's energy and possibly form 50% of a plant's energy cost. Many companies still take it easy and design & purchase pumping systems based on initial cost, without considering life cycle cost. Thus, Hydraulic Institute (HI) has taken an proactive initiative that educate how plants can increase efficiency and keep the energy low. It is called Pump Systems Matter (PSM). Read more HERE.

One of the modeling tool as a product of PSM, Pump System Improvement Modeling Tool™ (PSIM), a FREE educational tool available to help you understand the hydraulic behavior of pumping systems and design / evaluate a pumping system with both cost effective and energy efficient.

PSIM capabilities include :
  • System hydraulic calculations
  • Centrifugal & Positive Displacement pumps
  • Pump efficiency and BEP evaluation
  • Variable speed pumps
  • Flow & pressure control values
  • Impeller trimming
  • Automatic pump curve viscosity corrections
  • NPSH calculations
You may download the PSIM (Click HERE)

My 2-cents of thought...
Pumping system CAPEX is rather low compare to other equipments e.g. Reactor, Compressor, etc, thus less attention has been given to pumping system. Knowing pumping system is account for 50% of plant energy cost, OPEX is getting very important. The design and equipment selection strategy should be changed to Pumping system Life Cycle Cost consideration.

Knowing the important of LCC, management should pay extra emphasis in LCC and make it a policy and philosophy during initial design phase.

PSIM tool may be used in earlier design stage and updated from basic design to detailed design phase, last handover the model to operator for further optimization.

It is imperative to understand the pump system requirements and the properties of the fluids that will help you choose a right pumping equipments which are so diverse. It's true that pumps have become the prime movers in innumerable processes. Pumping system head varies from water surface elevations fluctuation to reservoir applications. Pumping applications include constant or variable flow rate requirements, serving single or networked loads, and consisting of open loops and closed loops.
