A Pump for Every Pool – Aurora 3801 Pool Pumps
Swimming pools today are all shapes and sizes with various water flow rates and liquid handling needs. Commercial pool applications in particular have numerous design and engineering considerations that can affect the kind of pool pump you need to maximize efficiency. As the pool industry has evolved toward increased water handling, temperature, and pressure, pumps have adapted to meet the needs of every application in various ways. For large commercial pools, this Best Point Efficiency (BEP) is met with Pentair’s Aurora 3801 pool pumps.
Based on the need to have swimming pool pumps mass-produced and in stock throughout the country, most residential pool pumps are built to industry standard sizes and horsepower and optimized for residential applications. These pumps have the benefit of operating relatively efficiently over a wide range of resistance or head-loss. With the advent of variable speed/flow pumps, stock pool pumps have become highly efficient and are now often used in smaller commercial aquatic facilities as well. And, with the 2019 launch of Pentair’s WhisperFloXF VS pool pump, this technology is now available up to 5 HP.
However, large commercial swimming pools require specialized pumping solutions with higher horsepower and flow rates. In addition, engineering factors such as vertical lift, friction and turns in the pipeline from the equipment room to the pool, collectively known as ‘TDH’ (Total Dynamic Head) or ‘head loss’ greatly impact the way water cycles through the system. Larger pool pumps require significantly more energy and cost to operate, so every bit of efficiency counts and pumps are manufactured based on standards and rarely run most efficiently in every application right out the box.
Aurora 3801 Series Pool Pumps Operate at Best Efficiency Point
In large commercial swimming pools, running your pool pump at its optimal point requires customization. One method is to add a variable frequency drive (VFD). This piece of equipment allows you to fine tune the power of your pump to run at an optimal point. Pentair’s Aurora 3801 pool pumps use another, just as effect method to control the operation of a pump – trimmed impellers. Permanently reducing the flow rate and head, trimming the impellers decreases the diameter of a standard-sized pump to the precise operating specifications. It also ensures the pump is designed to operate at or near the Best Efficiency Point (BEP) on the pump curve, and that the pump does not have a motor larger than what is required to meet the requirements of the application.
With 100 years of experience in design and manufacturing, Pentair’s highly reliable line of Aurora 3801 pool pumps have a clean, straightforward design made with upgraded materials for the best quality. Aurora 3801 Series pumps meet or exceed U.S. Department of Energy pump efficiency standards and feature shared hydraulics and premium materials as a standard offering. Pentair’s Aurora 3801 series have industry leading durability and are one of the most reliable large commercial pool pump solutions.
When ordering your Aurora 3801 pool pump, Pentair will use the designs and specifications from your engineer to create the optimal Aurora pump model for your swimming pool. During manufacturing, they trim the impellers down from the standard size to the exact measurements needed to make your equipment room run as efficiently as possible.
Pentair’s Aurora 3801 Series Pool Pump Standard Features
The Aurora 3801 pool pump is close coupled, eliminating the need for coupling alignment. The 3801 pool pump also features casing feet for easy back pullout, mechanical seal with stainless steel trim, Buna-N elastomers, ceramic seat, and carbon washer. Equipped with a stainless-steel shaft sleeve that extends the length of the seal plate, the pump shaft extension is gasket sealed from the pumped liquid. The impellers of the 3800 series pump are constructed of 316 stainless steel and are dynamically balanced and key locked to the shaft. Standard features include 316 SST impeller, 316 SST shaft sleeve, double volume on 4″ discharge and larger to reduce bearing loads, and gauge taps on suction and discharge.
Pentair’s Aurora 3801 Series pool pump has a capacity of up to 4,200 gallons per minute, head of up to 520 feet, and temperature tolerance up to 300 degrees Fahrenheit, assuring it can operate for any commercial swimming pool size.
To increase efficiency and save even more in energy costs, Pentair highly recommends adding a variable frequency drive to any pump. While trimming the impeller can reduce head and flow rate, it doesn’t reduce the speed of the pump like a VFD. With the combined fine tuning capabilities of trimming the impeller and a VFD, your pump will operate at the most efficient point on the curve for your pools design and flow rate.
The addition of a Pentair Aurora 3801 pool pump will upgrade your equipment room. Trimmed to meet exact specifications for the flow rate and head needs of your pool, the highly reliable 3800 series offer a premium solution for any commercial swimming pool application.
