Saving Energy through Innovation
Characteristics of Pumping SystemsCentrifugal pumps have the following benefits when operating at its Best Efficiency Point (BEP)
The main symptoms of pumping systems under non-optimal conditions are:
Opportunities Improving Pumping SystemsPumping systems are generally oversized; valves strangled or operate away from its Best Efficiency Point (BEP) and non-ideal suction conditions. Our approach is to do a complete analysis of your pumping system in order to save money.
• Smooth operation• Increased bearing life• Increased mechanical seals lifespan
• Reduced risk of cavitation• Minimum vibration• Noise Reduction.
• Existence of restricted valve• Existence of bypass flow• oversized pumps• Pumps operating away of its BEP• Changes in the conditions of the
initial pumping system• Large number of items• Noise presence due to cavitation• Pumping systems with different
pump models.

Services and SolutionsNeptuno Energy™ offers a complete solution for energy saving projects for new pumping systems as well as for existing facilities:
Evaluation of Pumping SystemsOur Pumping System Assessment is based on the Energy Assessment for Pumping Systems ASME EA-2 standard, allowing to understand the requirements of each system, their function and operation through the revision of the ultimate goal (and use) the system pumping, and then with a review of each component and the consideration of interactions between them, to assess opportunities for optimization. This process can be summarized in five simple steps:
By using proven techniques for assessment of his pumping system, Neptuno Energy™ offers a complete solution for energy savings. Efficiency improvements as minimum as 1% can lead to significant results in terms of cost savings and reduced CO2 emissions.
