Quick Answer
Jet pumps can be used in high-altitude areas, but they require careful selection and installation to overcome the challenges of low atmospheric pressure and freezing temperatures.
Selecting Jet Pumps for High-Altitude Areas
When choosing a jet pump for a high-altitude area, it’s essential to select a model specifically designed for low-pressure applications. Look for pumps with high suction lift capabilities, typically above 100 feet. For example, the Shurflo 2088-103-144 jet pump can handle up to 145 feet of suction lift, making it suitable for areas with elevations above 5,000 feet.
Installing Jet Pumps in High-Altitude Areas
Proper installation is critical to ensure the jet pump operates efficiently in high-altitude areas. To increase suction lift, install the pump above the well or water source to reduce the distance between the pump and the water level. Also, ensure the pump is protected from freezing temperatures by installing a freeze-proof casing or using a heat tape to keep the pump’s components from freezing.
Overcoming Challenges in High-Altitude Areas
High-altitude areas often experience low water temperatures, which can lead to pump cavitation and decreased performance. To overcome this challenge, install a preheater or use a pump with a built-in heating element to maintain a consistent water temperature. Additionally, consider using a variable speed drive to regulate the pump’s motor speed and optimize performance in low-pressure environments.
