Feature: 1. High Efficiency: This water transfer pump adopts a copper core motor with full power. The pump runs 2860 revolutions per minute and the maximum flow is 5.5m³ per hour. 2. Stainless Steel Material: This water transfer pump is made of 304 stainless steel meterial, which is safe and healthy, rust proof and corrosion resistant. 3. Firm: The pump has a fixed base with high hardness at the bottom. The installation hole is designed to facilitate the pump to be fixed on the ground and wall. 4. Fast Heat Dissipation: The pump is equipped with a heat dissipation wind wheel, which can efficiently dissipate heat and improve the working durability of the motor. 5. Wide Application: This jet pump is applicable to all kinds of water pressurization, high rise water supply pressurization, solar pressurization, water heater pressurization, bathroom pressurization, etc. Specification: Item Type: Jet pump Material: Stainless steel, ABS Weight: Approx. 11400g/402.1oz Size: Approx. 43x21x21cm/16.9x8.3x8.3in Rated Voltage: 220V, 50HZ Maximum Flow: 5.5m³/ h Rated Flow: 4.5m³/ h Speed: 2860r/min Power: 1500W Suction Lift: Approx. 9m/354.3in Maximum Lift: Approx. 55m/2165.4in Rated Lift: Approx. 45m/1771.7in Caliber: DN25, 1 inch Wide Application: Water pressurization, high rise pressurization, solar pressurization, water heater pressurization, bathroom pressurization, water tower water supply pressurization. Package List: 1 x Stainless Steel Jet Pump1 x Bottom Valve2 x Stainless Steel Adapter1 x Tape1 x Check Valve1 x Instructions Note: 1. The grounding wire must be grounded before use to prevent electric shock in case of poor insulation. For safety, be careful not to wet the power plug.2. Turn off the power supply before connect grounding wire. Never connect the ground wire to the gas pipe, otherwise there is a danger of explosion.3. Avoid running the water pump without water, which will shorten the service life of the water pump, and the motor is hot and prone to failure.4. Do not use any liquid other than water. When using soluble substances such as benzoic acid, flammable substances such as gasoline and high viscosity liquid, it is easy to cause fire.5. In cold weather, when using the water pump, do not wrap the hydrogen motor or pump head with quilt or cloth to prevent freezing, because the motor is hot and there is a risk of fire.6. Do not expose the water pump to direct light, which will affect the service life of the pump.7. During the process of water pump suction, do not move after the palm is blocked! It is best to fill the pump body with water! This test suction step can be tried several times to ensure that the water pump will not suck air in!
