Shakti QF5-14 4" Submersible Pump End (Only) - 16 GPM, 280' TDH, Stainless Steel
Replacing a worn pump end doesn’t always mean replacing the whole well system. If your motor is still in good shape, a pump end only is often the faster and more economical fix. Supreme Water Sales, an online water pump retailer based in New Port Richey, Florida, carries the Shakti QF5-14 Submersible Pump End (Only), a 16 GPM, 1.5 HP-class, stainless steel pump end from Shakti Pumps.
This guide covers what the Shakti QF5-14 is, how it performs, and where it fits, so you can match it to your well and water system.
What Is the Shakti QF5-14 Submersible Pump End?
The Shakti QF5-14 is a 4" submersible pump end, meaning it is sold without a motor. It is built by Shakti Pumps, a manufacturer that describes itself as one of the leading suppliers of submersible pumps in India. Supreme Water Sales offers it as part of its selection of submersible pump ends, alongside matching motors, control boxes and complete submersible pumps.
Because it is a pump end only, you pair it with a compatible 4" submersible motor. That makes it a good fit for:
- Replacing a worn or damaged pump end on an existing Shakti-compatible setup
- Building a custom pump and motor combination
- Upgrading an older well pump with stainless steel construction

Why Stainless Steel Matters in a Submersible Pump End
The Shakti QF5-14 is made of AISI-304 stainless steel, which gives good wear resistance and lower corrosion risk when pumping ordinary cold water with a minor chloride content. Stainless steel is also lightweight, which makes the pump end easier to handle, reduces installation and service time, and helps keep installation costs down. It also holds up well to wear, so the pump end performs close to new after servicing.
Built-In Features That Protect the Pump
The Shakti QF5-14 includes several design features that matter in real wells:
- Sand channel bearings: The bearings are water-lubricated and square-shaped, so sand particles can pass out of the pump with the pumped water instead of building up inside.
- Inlet strainer: This keeps larger particles from entering the pump.
- Non-return valve: It prevents backflow when the pump stops. Its short closing time also reduces the risk of destructive water hammer.
- Priming screw: It keeps the pump bearings lubricated and helps prevent dry running.
- Stop ring: This acts as a thrust bearing, limiting axial movement of the pump shaft and protecting the pump during transport and start-up.
One caution: if the water table drops below the pump inlet, neither the pump nor the motor is protected against dry running. Always size the setting depth with your well’s drawdown in mind.
Where the Shakti QF5-14 Works Best
Shakti lists these applications for the QF pump family:
- Raw water supply
- Irrigation systems
- Groundwater lowering
- Pressure boosting
- Industrial applications
At 16 GPM, the QF5-14 suits residential wells, small farms, irrigation lines and light industrial water supply where steady flow at higher head matters more than raw volume.
Understanding TDH Before You Order
TDH (Total Dynamic Head) is the total work the pump must do. It is calculated from operating pressure, depth to water in the well, pipe friction and elevation changes. The Shakti QF5-14 is rated at 280' TDH, so add these numbers up for your own system before you choose a pump end. If your total sits well outside the 200' to 360' range, a different model may suit you better.
Pair the Pump End With the Right Components
A pump end is one part of a working well system. Supreme Water Sales also carries the parts that go with it: replacement submersible motors, submersible motor control boxes, pressure tanks, pressure switches and wire splice kits. If sand or sediment is a concern in your water, adding sediment filtration downstream also helps protect your plumbing and fixtures.
