SK-4.5D Liquid/Water Ring Vacuum Pump for EPS Foam Machine
Product Description:
The SK-A series vacuum pumps are based on the traditional SK vacuum pump design, specifically tailored to meet the unique requirements of the plastic machine industry. These pumps have been engineered to overcome common challenges such as continuous operation when absorbing large amounts of water and difficulty in starting due to scaling from hard water. They are widely used in tubing machines and molding machines. The product range includes models like SK-0.15A, SK-0.3A, SK-0.5A, SK-0.8A, SK-1.2A, SK-2A, SK-3A, with motor power ranging from 0.55 kW to 5.5 kW, capacity from 0.15 m³/min to 3 m³/min, and ultimate vacuum of -0.095 MPa.
