Vertical Deep Well Jet Pump: A Comprehensive Guide

Vertical deep well jet pumps are designed to efficiently pump water from depths greater than 25 feet, making them an ideal choice for homes, farms, and cottages with deep wells. These versatile pumps, also known as convertible jet pumps, can be used for both shallow and deep well applications, providing a flexible solution for a variety of water supply needs.

Understanding Vertical Deep Well Jet Pumps

Vertical deep well jet pumps are characterized by their ability to lift water from significant depths, typically ranging from 25 feet to as deep as 250 feet. This makes them a popular choice for properties with wells that are too deep for traditional shallow well pumps. These pumps utilize a unique design that incorporates a jet assembly, which creates a vacuum to draw water up from the well and then pressurizes it for distribution.

Key Features and Specifications

Vertical deep well jet pumps come with a range of features and specifications that cater to different water supply requirements. Some of the critical technical details to consider include:

Maximum Flow Rate

The maximum flow rate, measured in gallons per minute (GPM), determines the pump’s capacity to move water. Typical flow rates for vertical deep well jet pumps range from 50 GPM to 150 GPM, with higher-end models capable of reaching up to 200 GPM.

Maximum Lift

The maximum lift, measured in feet, represents the deepest depth from which the pump can effectively draw water. Vertical deep well jet pumps are designed to handle depths ranging from 25 feet to as much as 250 feet, with some models capable of even greater lift capacities.


The horsepower (HP) of the pump’s motor determines the power output and, consequently, the pump’s ability to handle larger water demands. Vertical deep well jet pumps typically range from 1/2 HP to 3 HP, with higher horsepower models suitable for more extensive water supply needs.

Voltage and Phase

The voltage (V) and phase (single-phase or three-phase) requirements of the pump’s motor must be compatible with the available electrical supply. Vertical deep well jet pumps are available in a variety of voltage configurations, including 115V, 230V, and 460V, to accommodate different electrical systems.

Pressure Regulation

Many vertical deep well jet pumps feature advanced pressure regulation systems, such as the automatic pressure regulator found in the Pentair Myers MVPH Series. These systems help maintain consistent water pressure, reducing “hunting” and ensuring a quieter, more efficient operation.

Installation and Maintenance Considerations

Proper installation and maintenance are crucial for the optimal performance and longevity of a vertical deep well jet pump. Here are some key considerations:

Priming the Pump

Before starting the pump, it is essential to prime the pump housing by filling it with water. This removes any air pockets and ensures the pump can effectively draw water from the well.

Electrical Grounding

Ensuring the pump is properly grounded is crucial for safety and to prevent electrical shocks. Follow the manufacturer’s instructions carefully when connecting the pump to the electrical system.

Specialized Tools and Equipment

Installing or repairing a vertical deep well jet pump may require access to specialized tools and equipment, such as pipe wrenches, drills, and multimeters. It is recommended to have some basic plumbing and electrical knowledge and experience.

Professional Assistance

For complex installations or repairs, it is always advisable to consult with a professional plumber or electrician, especially if you have any doubts or concerns about the process.


Vertical deep well jet pumps are a versatile and efficient solution for homes, farms, and cottages with deep wells. By understanding the key features, specifications, and installation/maintenance requirements, you can ensure the proper selection and operation of these pumps to meet your water supply needs. Remember to always follow the manufacturer’s instructions and, if necessary, seek the guidance of a professional for a successful and safe installation or repair.
