Air Compressor Pump Head, 4HP Replacement Air Compressor Pump, Cast Iron Air Compressor Pumps with Multiple Pump Heads & 3 Cylinder for Chemical Industry Light Industry

DetailsThreaded Oil Cap: It helps to achieve convenient and tight connections to avoid oil leakage.Standard Pulley: It plays a balance and correction role to avoid bearing displacement, making the machine run smoother.SpecificationColor: BlackMaterial: Cast Iron, AluminumPower Source: ElectricCylinder: 65mm*3Maximum Working Pressure: 0.8MPa/115PSIMaximum Speed: 1030rpm (Matching the Overall Machine Speed)Exhaust Volume: 0.36m³/min/12.7cfmPipe Interface: 19mm/ 3/4inMatching Motor Power: 3KW/4HPGross Weight: 21kg/46.29 lbsPackage Size: 44*33*38cm/17.32*12.99*14.96inPackage Included1*Air Compressor Pump3*Air Filter MufflersNotesNote: The pulley speed should not exceed 1000r/min. It should match the motor power. Please pay attention to the product specifications before ordering.When placing the pump head, the motor pulley and the belt pulley must be in the same straight line. The more aligned, the less vibration.After the screws are installed, the belt shall be tightened. If the belt is loose, please move the motor. After the screws are tightened, reinstall the belt.The new machine must be filled with engine oil before starting(Special engine oil for air compressors must be used), and the engine oil shall be added to the center of the red point of the oil mirror. Please change the oil for half a month for the first time, one and a half months for the second time, and change the oil for the next four to five months. Please pay attention to observation at ordinary times. If it is not enough, replenish it in time.The rotation direction of the pump head is clockwise. If it reverses, please adjust it in time.Please replace the air filter regularly. Under normal conditions, it must be replaced in two to three months, and in case of a poor environment, it must be replaced in one month.The operation of the machine will produce high temperature, please be careful not to burn!

• 【Sturdy and Durable】 Made of cast iron and aluminum with high strength and good rigidity, together with a painting finish, it is resistant to wear, ensuring excellent performance and long service life.
• 【Excellent Performance】 The large crankcase makes the machine run smoother and less prone to oil leakage during operation. The extended cylinder(65mm in diameter)increases the stroke to achieve rapid inflation.
• 【Improving Efficiency】 It can provide gas supply to multiple devices simultaneously by controlling the switches of different pump heads, avoiding single-point faults affecting the entire production line and improving gas supply efficiency.
• 【Faster Heat Dissipation】The dual iron breathing nozzles reduce the internal pressure and temperature of the machine. The aluminum tube and evenly distributed heat dissipation fins on the outside make the machine dissipate heat faster, ensuring stable operation and extending the service life of the host.
• 【Low Energy Consumption & Low Noise】 Compared to compressors with a single pump head, multiple pump heads can reduce the pressure and flow rate of each pump head, thereby reducing the power and energy consumption of the compressor. The air filter with a silencing function makes it operate at low noise.
