Wherever pumping systems are present–in environments such as buildings and water / wastewater and oil and gas facilities–energy consumption exerts a major influence on cost. Despite the fact that electrical energy cost represents 40% of the total cost of ownership of pumping systems, many organizations fail to introduce the proper steps to leverage cost reduction through efficiency improvements. To solve this dilemma, the following major barriers need to be recognized and addressed: Lack of proper metrics – Energy efficiency has traditionally not been used in assessing performance. In most organizations, the responsibilities of energy procurement and efficient operations are separate and consistent / standardized metrics are not utilized. Knowledge gap – A lack of awareness in energy efficiency opportunities is prevalent and, as a result, potential savings and other benefits are missed. Fear of investment – Operations personnel often struggle to present attractive large or even small investments to their finance organizations.

This paper demonstrates how deployment of an energy management plan, with limited investment, can provide reductions in pumping systems TCO while maintaining sustainability objectives. Any sound energy plan should take into account the following three steps: 1. Energy efficiency management 2. Asset management 3. Energy cost management For the purposes of this paper, the scope of a pumping system will be defined as encompassing all related elements starting from the point of the electrical utility connection down to the point of end use. This paper will illustrate how energy management best practices can result in a 20% reduction in TCO and a return of investment (ROI) within 24 months.

Energy efficiency is now a global high priority for both industrialized and emerging countries. The Rio conference and Earth Summit of 1992 and the Kyoto Protocol of 1997 resulted in the signing of a global treaty that sets binding targets for reduction of greenhouse gas emissions. The International Energy Agency (IEA) and various governments and non-governmental organizations (NGOs) agree that the reduction of CO2 emissions and the resulting energy savings can be achieved through the deployment of energy efficient products and systems. The challenge, however, is that the nature of production in industrial environments is in a constant state of flux. Production cycles, for example, are influenced by variables such as market demand, weather, and local regulations. As a result, factory and building operators need to understand how and when energy is used in order to minimize consumption and related costs. The pump system energy management approach discussed in this paper will review the nature of efficiency loss not only for individual components within the system, but also for the system as a whole, integrated entity. In pumping systems, most inefficiency comes from: A mismatch between the pump deployed and the actual system requirement (i.e., undersized or oversized) The improper use of throttling valves and damper technologies to control the flow of liquids These two elements imply that the way pumping systems are controlled plays a major role regarding how efficiency can be improved. Control systems themselves are composed of both hardware and software components. On the hardware side, variable speed drives are a primary enabler of high efficiency performance.

DCS Lafert Formally Introduces New Plant in San Dona di Piave 1 400x275

The new production plant is officially in operation after its formal unveiling at Lafert’s 60th anniversity celebrations in San Donà di Piave, Italy, close to the historic headquarters. 

The 130 000 sq foot plant was developed to increase production capacity and meet the growing demand for IE5 Super Premium Efficiency motors, while also providing new storage areas for raw materials and finished products. In this plant alone, Lafert is able to produce up to 1400 pieces per day and can ship 4-5 international containers per week thanks to the internal customs area. 

The project began in September 2020 with the aim of building a brand-new manufacturing plant to produce high efficiency permanent magnet motors, specifically intended for pumping applications. The plant was designed and built with extensive automated production capabilities including fully automated production lines. Today the plant employs 50 operators who have been carefully trained to work in synergy with the production lines. The plant delivers maximum comfort in the working conditions of the operators in terms of light, space, services, and other factors that affect the well-being of employees.

DCS New LUTZE DRIVEFLEX and MOTIONFLEX VFD Cables from Automation Direct 1 400x275

AutomationDirect has added new LUTZE DRIVEFLEX® and MOTIONFLEX® variable frequency drive cables which provide supreme protection against electromagnetic interference (EMI).

These cables are available in 18 to 8 AWG sizes and include four black conductors with a green/yellow ground conductor of the same gauge. Each conductor is labeled for easy identification and is covered in a cross-linked Polyethylene (XLPE) insulation (type XHHW-2) that is oil and sun resistant, suitable for dry, damp, or wet locations, and approved for direct burial.

The DRIVEFLEX series has a black PVC outer jacket ideal for stationary applications, while the MOTIONFLEX series has a black thermoplastic elastomer (TPE) outer jacket designed for continuous motion applications. Both cables are tray cable-exposed run rated (TCER) for use in cable trays with or without conduit, which can significantly reduce installation costs.

The new DRIVEFLEX series cable starts at $2.58 /ft. and the MOTIONFLEX series cable starts at $3.67 /ft.  Both cables are made in the USA and can be ordered cut to length in 1-foot increments with a 10ft minimum.
