4-5HP Air Compressor Pump Replacement, Heavy Duty Cast Iron Compressor Pump 115PSI 3 Cylinder 10-12 CFM Max

Details--Simple Installation: The integrated structure and pre-drilled holes on the base allow for easy installation.--Threaded 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.ApplicationIt is widely used in the chemical industry, light industry, textile, food processing, health, electronics, machinery, mining, construction, scientific research, etc.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 MufflersNotes-- Note: 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. -- The rotation direction of the pump head is clockwise. If it reverses, please adjust it in time.

• 🔩【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, corrosion, and rust, ensuring excellent performance and long service life.
• 🔩【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.
• 🔩【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.
• 🔩【LOW ENERGY CONSUMPTION】 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.
• 🔩【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 NOISE】 The air filter with a silencing function makes it operate at low noise, providing you with a relatively quiet working environment.
