What is a cooling jacket for pump?
A submersible pump cooling jacket enables a portion of the pumped liquid or an external liquid to be circulated around the motor stator housing. This absorbs excess heat by forced convection, ensuring efficient cooling of the pump. Especially dry-installed pumps need special motor cooling.
What causes a submersible pump to overheat?
Low/High External Cooling Water Flow.
Incorrect application or design. Plugged or blocked suction inlet. Loss of suction. Closed or blocked discharge.
What is a flow sleeve?
Pump Sleeves help direct water flow to properly cool motors. Submersible pump motors require water flow over them to dissipate heat.
What is a flow inducer sleeve?
DIY Pump Sleeves help encourage water flow cooling around your pump’s motor when horizontal, and in sandy wells, encourages sand to fall down safely past the pump intake. We use the term ‘pump sleeves’ but it’s also commonly called a ‘flow sleeve’, ‘flow inducer’, and ‘pump shroud’.
How does a cooling jacket work?
Fermentation tank cooling jackets are composed of flexible material with coolant channels running within them. When wrapped around a brewing vat, coolant flowing within the jacket’s channels will absorb heat from the brewing liquid by a simple heat exchange process.
Do submersible pumps have thermal overloads?
Submersible pump motors will burn up if not enough water flows past them. The thermal overloads for them are located in the control box and respond to current flow, not the actual temperature of the motor.
What can damage a submersible pump?
- Dry Running. This is where the water level drops to a point where the pump cannot draw a decent amount of water and/or starts to create a lot of disturbance in the water. …
- Running on the Right of the Curve. …
- Specific Gravity. …
- Cable Damage. …
- Dead Head. …
- Not allowing for Discharge Piping.
What is a pump shroud?
Electrical submersible pumps
The motor shroud is designed to provide cooling to the motor when fluid velocities are below minimum. A motor shroud is installed to increase the fluid velocity past the motor in wells with large diameter casing or to allow the lowering of the motor below perforations.
How deep should a submersible pump be in a well?
Submersible well pumps should never be at the bottom of a well. Instead, they should be placed 10 to 20 feet from the bottom of the well. How deep the submersible pump is in the well will depend on the size of the well itself.
What is a flow inducer?
Flow Inducer Towers manufactured by Orenco® are used to house two to five Orenco high-head effluent pumps in recirculation tanks or final discharge tanks, following filtration or secondary treatment, in commercial and municipal wastewater systems.
What type of pipe is used for water wells?
Poly pipe is fast becoming the most common and efficient way to install a submersible well pump. With most well depths up to 350′ the 160psi HDPE Black Poly Pipe shown below in green is the top choice for well pumps and solar well pumps.
How long do shallow well pumps last?
A shallow well pump is also called a centrifugal pump and is used above ground on wells with a high water table. These pumps generally last for 8 to 10 years as they don’t have much pressure put on them to perform.
Submersible pump cooling jacket
A submersible pump cooling jacket enables a portion of the pumped liquid or an external liquid to be circulated around the motor stator housing. This absorbs excess heat by forced convection, ensuring efficient cooling of the pump.
Especially dry-installed pumps need special motor cooling. If needed, a submersible pump cooling jacket provides extra motor cooling if the pumped liquid is warm or if the pumps are required to pump continuously. The same applies if the liquid is pumped to below the level of the motor.
The cooling jacket can also be designed as an aluminum casing around the stator house. In this way the heat will be transferred to the pumped liquid via the aluminum casing.

Pump Sleeves
Pump Sleeves help direct water flow to properly cool motors.
Submersible pump motors require water flow over them to dissipate heat. In open water, such as a lake or cistern or in large diameter wells, heat dissipation becomes a problem since water is likely to flow directly into the intake of the pump, instead of flowing over the motor. In these situations, a pump sleeve or shroud is required. Pump sleeves are also required if the well is top feeding (water flows in from above), or if the pump is placed below screens or perforations, and sand is able to fall into the pump inlet. As a side note: pump sleeves, flow sleeve, flow inducer sleeve, and pump shroud all mean the same thing!
A PumpSleeve / FlowSleeve is simply a PVC pipe that prevents water flow into the pump from the lateral directions, and directs waterflow to enter from the motor’s end, allowing for water to pass over the motor first before entering the intake.
Pump sleeve kits are available to help simplify assembling a complete pump sleeve. These kits do require a PVC pipe, which are available at your local hardware store. Just be sure to have the pipe cut about a foot longer than your assembled pump. PVC pipe with thinner wall ( e.g. Class 125 or SDR 35) usually has larger inside diameter, which is recommended to use for making a pump sleeve.
Below is a chart for minimum flow rate required by the motor per well casing diameters. If your pump operates at a lower flow-rate than stated, you will require a pump sleeve.

DIY Solar Pump Sleeves / Pump Shrouds
DIY Pump Sleeves help encourage water flow cooling around your pump’s motor when horizontal, and in sandy wells, encourages sand to fall down safely past the pump intake. We use the term ‘pump sleeves’ but it’s also commonly called a ‘flow sleeve’, ‘flow inducer’, and ‘pump shroud’.
While DC Brushless Motors used in RPS Solar Pumps do not generate nearly the heat of induction motors, cooling of the lower motor end is still important. When pumping from larger water sources, such as above ground tanks, cisterns, ponds, or in much larger diameter wells, heat dissipation is a bigger issue as water’s path of least resistance is flowing directly into the middle intake of the pump, and not flowing around the pump’s motor. In these situations, a pump sleeve is highly recommenced.
In the case of sandy wells or rusty casing wells, pump sleeves are also recommended if the well is top feeding (water flows in from above), or when a pump is placed below the wells perforations/screens so that the sand is able to fall down past the pump and get pulled into the pump’s intake.
A common DIY Pump Sleeve we recommend is simply a piece of 3″ or 4″ PVC (depending on RPS Pump Model and Well Casing Size) and with a reducing coupling at the top that prevents water from flowing into the middle pump intake, and instead encourages it to flow from the bottom, up around the motor to cool it before entering the intake. Most recommend cutting the PVC about a foot longer than your assembled pump. PVC pipe with thinner walls is fine. A rubber reducing coupling with hose clamps can be used to fasten around the wire and plumbing at the top, expanding to hose clamp on the PVC pipe to hold it in position and prevent it from slipping down and off the pump.

Cooling sleeve kits for Franklin Electric submersible motor pumps
Franklin Electric is expanding its portfolio of accessories and now offers cooling sleeves for all Franklin Electric motors.
The heat loss generated by the submersible motor must be dissipated to the pumped medium by means of convection.
If the minimum cooling speed along the submersible motor cannot be guaranteed, it is mandatory to install a cooling sleeve to generate sufficient cooling. Inadequate cooling can have various causes, such as a well diameter that is too large, the application in “open” water, insufficient flow rate or water inflow from above (top feeding).
To provide cooling, the pump-motor unit is supplemented by a cooling sleeve. This separate „sheet metal jacket” is sealed above the pump inlet. The pumped medium is thus sucked in from below and directed past the motor to dissipate the generated motor heat loss (convection).
Appropriate brackets and inlet strainers are available for horizontal installation.
Kit components:
1 Cooling sleeve tube (Stainless steel)
2 Pump sealing ring (EPDM) with drinking water approval
3 Motor spacer
4 Pipe clamps
5 Filter strainer (accessories)
6 Console (accessory for horizontal mounting)
Cooling sleeves – horizontal and vertical
Cooling sleeves – horizontal and vertical
Cooling sleeves improve submersible pump operation by allowing an internal water flow to disperse the heat.
Their use is recommended when the fluid speed is insufficient to cool the motor, for example when the well diameter is much larger than the pump diameter, or when the pump is installed in a tank.
The horizontal version of the cooling sleeve has support mounts.

Flow Sleeves for Submersible Well Pumps
Flow Sleeves for Submersible Well Pumps
When is a flow sleeve required?
Submersible well pump motors are designed to operate with a cooling flow of water over and around the full length of the motor. In water up to 86 degrees Fahrenheit, a flow of 0.25 feet/second for 4” motors rated 3 horsepower and higher, and 0.5 feet/second for 6” and 8” motors is required for proper cooling. If the minimum flow is not maintained, the motor can overheat. In these cases, flow sleeves, also known as flow inducer sleeves, must be used to provide sufficient cooling.
The following conditions require a flow sleeve as the minimum flow rate will not be maintained:
Pump is in an open body of water (for example, here in northern Idaho we have a lot of clients that have submersible well pumps in a lake)
Large diameter wells (use Franklin Electric AIM Manual Table 6 to determine requirements, shown below) Click here to go to AIM Manual
Pump is in a rock well or below the well casing
The well is “top feeding”
Pump is set in or below screens or perforations
Table 6 from Franklin Electric AIM Manual below shows the minimum GPM required for proper cooling.
The figure below from the Franklin Electric AIM Manual shows a typical flow sleeve.
If a standard motor is operated in water over 86 degrees Fahrenheit, water flow must be increased to 3 feet/second to maintain safe motor operating temperatures. Consult the AIM Manual for the procedure to determine proper requirements.
Franklin Electric also offers Hi-Temp motors designed to operate in water at higher temperatures or lower flow conditions. Consult motor specifications and manual for installation requirements.
