Kite and Wing Inflation • Single/Double Stroke • Sand Protection • L and XL Sizes
CORE Pump 3 L/XL
Smooth, efficient inflation with high airflow, a calibrated pressure gauge and protection against sand entering your pump or bladder.
The CORE Pump 3 is a dependable high-volume pump developed for fast, controlled inflation of CORE kites and wings. Its low-friction piston system and large internal air passages reduce pumping effort, while the rotary valve lets you switch between double- and single-stroke operation. A calibrated pressure gauge keeps the current pressure visible, and CORE’s Sand Guard membrane helps prevent grains of sand from entering the pump and inflatable bladder. Choose the compact 2.0 L Pump L or the taller, higher-volume 2.9 L Pump XL.

Why You’ll Love the CORE Pump 3
Fast High-Volume Inflation
The long pump barrel, large-diameter air path and double-stroke setting move a high volume of air with every complete pumping cycle, helping inflate larger kites and wings efficiently.
Easier Final Pressurization
When resistance increases near the target pressure, use the rotary valve to switch from double-stroke to single-stroke operation for a more manageable final pumping stage.
Protection from Sand
CORE’s Sand Guard foam membrane helps stop grains of sand from entering the suction opening. This protects the pump’s smooth operation and reduces the amount of sand that can be pushed into a kite or wing bladder.
Choose Your Preferred Size
Pump L offers a more compact 2.0-liter format, while Pump XL adds height and increases displacement to 2.9 liters for more air volume and a more upright pumping position.
Key Features
Low-Friction Pump Action
High-quality materials, seals and coatings allow the piston to move smoothly through the cylinder, reducing unnecessary resistance during inflation.
Single/Double-Stroke Switch
A rotary valve on the rear of the pump changes between double-stroke inflation for high-volume filling and single-stroke inflation for adding pressure with less resistance.
Calibrated Pressure Gauge
The integrated gauge continuously displays inflation pressure, helping you stop at the pressure specified on the kite or wing valve and in the product manual.
Sand Guard Membrane
A specialized foam membrane protects the pump’s suction opening from sand, supporting smoother operation and helping keep abrasive particles away from the inflatable bladder.
Rotating Hose Connector
The hose connection between the handles uses a threaded twist-lock design that allows the hose to rotate freely, improving flexibility and reducing its tendency to kink.
Maximum Hose Diameter
The large hose diameter and enlarged internal air path support efficient airflow from the pump cylinder to the inflatable.
Long Barrel and Stroke
The extended pump cylinder increases the air moved during each stroke. Its added height also supports a more upright pumping posture, particularly with the XL version.
Ergonomic Handles
Shaped handles make it easier to apply body weight and pumping force comfortably when filling higher-volume kites and wings.
Heavy-Duty Pump Leash
CORE’s pump leash is twice as thick as a conventional pump tether and uses a reinforced kite hook to secure the inflatable during pumping.
Scratch-Resistant White Body
The white pump body is less susceptible to visibly showing scratch marks caused by sand and everyday use.
CORE Pump 3 L vs. XL
| Specification | Pump L | Pump XL |
|---|---|---|
| Air Volume | 2.0 L | 2.9 L |
| Overall Height | 50.5 cm | 61.5 cm |
| Handle Width | 27.5 cm | 27.5 cm |
| Foot Depth | 11.5 cm | 11.5 cm |
| Weight | 1,045 g including hose and bag | 1,200 g including hose and bag |
| Primary Advantage | More compact for storage and transportation | Greater air displacement and a taller, more upright pumping position |
Size recommendation: Choose Pump L when compact storage and lower weight are priorities. Choose Pump XL when you regularly inflate large kites or wings and want maximum air volume per stroke.
Single and Double-Stroke Inflation
Double-Stroke Mode
Double-stroke mode moves air on both the upward and downward strokes. Use it during the initial inflation stage when the inflatable requires high volume at relatively low pressure.
Single-Stroke Mode
As pressure rises and pumping becomes harder, switch to single-stroke mode. This reduces resistance and provides greater control while approaching the specified pressure.
Monitor the Gauge
Watch the calibrated pressure gauge throughout the final inflation stage and stop at the pressure specified by the equipment manufacturer.
Follow the Equipment Limit
CORE intentionally does not mark a universal ideal range on the gauge because recommended pressure varies by model. Always follow the maximum PSI shown on the valve or in the corresponding manual.
Valve Compatibility
CORE Kites and Wings
The Pump 3 is designed for inflation of compatible CORE inflatable products using the appropriate supplied connection.
Included Valve Adapter
CORE includes an adapter that expands compatibility beyond CORE products to many other kite and wing valve systems.
Compatibility note: The included adapter supports many valve systems, but universal compatibility with every brand and valve generation is not guaranteed. Confirm that the fitting locks securely before pumping.

Frequently Asked Questions
What is the difference between Pump L and Pump XL?
Pump L is 50.5 cm tall and has a 2.0-liter volume. Pump XL is 61.5 cm tall with a 2.9-liter volume, providing more air per stroke and a more upright pumping position.
Does the pump include a pressure gauge?
Yes. The CORE Pump 3 includes a calibrated pressure gauge that displays pressure throughout inflation.
Why does the pump have single- and double-stroke settings?
Double-stroke mode moves more air during initial inflation. Single-stroke mode reduces resistance as pressure increases, making the final stage easier to control.
What does the Sand Guard do?
The Sand Guard membrane helps prevent sand from entering the pump’s suction opening, protecting the pump mechanism and reducing the chance of sand being pushed into the bladder.
Can it inflate products from other brands?
CORE includes an adapter for use with many other valve systems. Confirm that the selected fitting is secure and compatible before inflation.
Are the hose and bag included?
Yes. CORE lists the pump, hose, storage bag and heavy-duty pump leash as included. A valve adapter is also described as included.
