Excel Fluid Group offers the Barnes Envie3 high-efficiency air-filled motors, which are designed without application limitations. This advanced generation of dry pit submersible pumps is capable of operating in both wet and dry pit environments. These pumps integrate Barnes’ and Deming’s established solids handling and chopper wet ends with a premium efficient IE3 motor, suitable for both vertical and horizontal configurations.
The reduced continuous minimum submergence requirement of the Envie3 offers significant advantages for both new lift stations and aftermarket replacements. In both scenarios, water can be efficiently pumped down to the top of the volute, aiding in the prevention of debris accumulation and maintaining a cleaner lift station. This results in extended intervals between vacuum truck visits, thereby reducing maintenance costs by $500–$2,000 for standard stations and up to $10,000 for hazardous waste stations.
For new lift stations, the decreased required operating volume permits the construction of a shallower and more cost-effective wet well. In the case of aftermarket replacements, the Envie3 pumps provide an expanded operating range, allowing for increased pump capacity. Customers can effortlessly enhance the station's flow by augmenting the motor horsepower.
The motor operates cooler due to the integrated cooling system. Elevated temperatures can significantly decrease motor lifespan. As reported by the U.S. Department of Energy, a 10-degree increase in operating temperature can halve the operational lifespan. The Envie3's integrated cooling system employs a chamber that circulates coolant/glycol around the motor, maintaining a lower temperature and thereby extending the overall lifespan of the pump.
A more efficient motor results in reduced energy consumption. When comparing two pumps, the one operating at a cooler temperature will transfer more energy to the fluid than one operating at a higher temperature. Consequently, this allows for increased pumping capacity per horsepower, or alternatively, the use of a lower horsepower motor to achieve the same output. Additionally, the higher efficiency motor results in a reduced amp draw, enabling some installations to accommodate a larger horsepower motor to enhance pump capacity.
The efficiency of standard oil-filled motors is considerably lower than that of IE3 air-filled motors, leading to substantial annual energy cost savings when transitioning from oil-filled to air-filled systems. Depending on the specifics of the previous installation, the cost savings in energy could allow the pump to recoup its initial investment within three years.
The Envie3 is offered with both chopper and non-clog wet ends. These pumps incorporate Crane’s established non-clog and chopper wet ends, equipped with a premium efficient IE3 motor capable of operating in both vertical and horizontal configurations. The Envie3 represents Barnes’ and Deming’s most versatile and efficient solution to date, effectively addressing clogging issues across various applications, thereby optimizing time, cost, and resource management.
