GRI HP2 Double Action Pump – SUP & Kayak

Make inflating your inflatable SUP or kayak easier with the GRI HP2 Double Action Pump. Its single-chamber, double-action design pumps air on both the push and pull stroke, providing efficient airflow during the initial stages of inflation.

The HP2 features a 2 × 1.8L chamber capacity, high-airflow piston and aluminium shaft. As inflation pressure increases, the pump can be changed from double action to single action to make higher-pressure inflation easier.

A built-in 0–26 PSI pressure gauge allows you to monitor inflation pressure, while the robust construction, extra-resistant hose and anti-sand filter make the HP2 a practical pump for regular use with inflatable SUPs and kayaks.

KEY FEATURES

• Double-Action Inflation: Pumps air through the hose on both the push and pull stroke for efficient high-volume inflation.
• Single-Chamber Design: Provides a straightforward and efficient inflation system.
• 2 × 1.8L Chamber Capacity: Provides high air volume during inflation.
• High-Airflow Piston: Designed to provide efficient airflow while reducing pumping effort.
• 0–26 PSI Pressure Gauge: Built-in gauge allows you to monitor inflation pressure.
• Aluminium Shaft: Lightweight and durable shaft construction.
• Anti-Sand Filter: Helps reduce the entry of sand and debris into the pump.
• Shockproof Gauge: Designed to withstand the demands of outdoor use.
• Extra-Resistant Hose: Durable inflation hose for regular use.
• Bayonet Adapter: Includes a bayonet-style adapter for common high-pressure valves.

DOUBLE & SINGLE ACTION OPERATION

The HP2 starts in double-action mode, allowing the pump to move air through the hose on both the downward and upward strokes. This provides higher airflow when rapidly increasing the volume of your inflatable SUP or kayak.

As the pressure inside your inflatable increases and the pump becomes harder to operate, remove the toggle cap to change the pump to single-action mode.

In single-action mode, air is pumped through the hose on the downward stroke only. This reduces the effort required as inflation pressure increases.

INFLATION TIPS

1. Place the pump on a level, solid surface.
2. Connect the inflation hose securely to the pump.
3. Connect the hose to the inflation valve on your SUP or kayak.
4. Begin pumping in double-action mode to quickly increase the air volume.
5. Continue using double action while pumping remains comfortable.
6. When the pump becomes harder to operate, remove the toggle cap to change to single-action mode.
7. Continue pumping until your inflatable reaches the manufacturer's recommended pressure.

Important: Always inflate your SUP or kayak to the pressure recommended by its manufacturer. Do not assume that the pressure range shown on the pump gauge is the recommended pressure for your inflatable equipment.

PRESSURE GAUGE

The HP2 features an integrated 0–26 PSI pressure gauge (0–1.8 bar), allowing you to monitor the pressure while inflating.

Use the pressure gauge as a guide and always follow the inflation pressure specified by the manufacturer of your particular SUP or kayak.

IMPORTANT INFORMATION

This pump is designed for inflating compatible inflatable SUPs, kayaks and other suitable inflatable equipment.

Always check that the supplied adapter and hose connection are compatible with your inflatable's valve before use.

Always follow the manufacturer's recommended inflation pressure for your SUP or kayak. The pump gauge range does not indicate the pressure that your inflatable should be inflated to.

Keep the pump, hose and connections free from excessive sand, dirt and debris. The integrated anti-sand filter helps reduce contamination, while appropriate cleaning and storage will help maintain the pump.
