Motor cooling protection
Flow sleeves force water past the motor before it reaches the intake. That maintains the cooling flow needed to remove heat and protect submersible motors.
SEC. 07 — FLOW SLEEVES Custom fabrication
Custom stainless steel flow sleeves for submersible pumps.
We custom manufacture stainless steel flow sleeves for submersible pumps of all sizes and configurations. Each sleeve is built to direct cooling water past the motor according to manufacturer requirements, and can be configured to support devices mounted below the pump, including the Lamnaflo Suction Flow Control System. We custom build these units and ship them anywhere.
APPLICATIONS
Designed around the actual pump, motor, and well geometry.
These sleeves are used where natural flow paths do not provide adequate motor cooling velocity, and wherever the assembly needs a durable stainless platform for accessories installed below the pump. They are also widely used as cooling shrouds in many other applications.
Cooling shrouds for many applications
We build sleeves for small and large pump assemblies, standard and non-standard dimensions, retrofit applications, and unusual well or screen conditions. The same construction serves as a cooling shroud in a wide range of installations.
Accessory mounting
Sleeves can be fabricated to accommodate the Lamnaflo Suction Flow Control System and other components located below the pump, with support rings, cable notches, adapter sections, and special clearances as needed.
HOW IT WORKS
Direct the water where the motor needs it.
When a pump is set in a wide casing, screened interval, or open-water condition, water may take the shortest path to the intake and bypass the motor. A properly designed sleeve changes that path and makes the cooling flow travel along the motor housing first.
- Matches manufacturer cooling requirements for the motor.
- Supports reliable operation in large-diameter or open intake installations.
- Built in stainless steel for durability and long-term service.
- Configured for support rings, cable notches, adapter sections, and special clearances as needed.
INFORMATION NEEDED
We fabricate each sleeve to fit the application.
For quoting and fabrication, send the key assembly and well dimensions. That lets us size the sleeve correctly and confirm the final configuration before manufacturing.
