Linear circulating pumps are manufactured with advantages such as low noise performance, A or B power consumption category, as well as a 1-year warranty. These types of pumps are made in half-inch to six-inch sizes and its engine speed They are 1,500 and 3,000 rpm and often have cast iron and steel body material. Their impellers are cast iron, steel and brass, and they also do not have negative suction. In other words, in order to move the fluid, that fluid must be so-called mounted on this type of pump. These products 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 available in two types: intermediate (coupling) and autoterm 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
