Linear circulator pumps are made in half-inch to six-inch sizes. These products are produced with cast iron and steel body material, as well as cast iron, steel and brass impeller material. The circulator pumps are made in two types of single-phase and three-phase and single-phase, two-phase, three-phase and four-phase. These electric pumps are classified as A and B for optimal energy consumption. There are two types of intermediate (coupling) and atheroma or dry motor and without intermediaries. General specifications of linear circulator pumps: 1. It has standard electric motors with low power consumption of Electrogen Company 2. It has an exclusive chassis to silence the electric motor and eliminate vibration. It has a thermal sensor to prevent the electric motor from burning out. Has a warning siren when the electric pump fails 5. Maximum pressure tolerance: 12 bar 6. The pump shaft is grounded by mechanical flooding 7. Electropumps coupled with intermediate coupling 8. Butterflies are made of fibrous polyamide, which is resistant to corrosion and sediment. The shafts are made of stainless steel alloy 10. Types of sealing felt bowls for different temperatures, pressures and fluids 11. Has a one-year warranty
