One of the characteristics of this type of electric pump is extremely low-noise operation.
These pumps are manufactured in sizes ranging from half an inch to six inches.
The motor speed (RPM) of this type of electric pump is 1500 and 3000 RPM.
The body material of these pumps is typically cast iron and stainless steel, and their impeller material is cast iron, stainless steel, and brass.
These pumps do not have negative suction (negative lift), meaning that in order to transfer the fluid, the fluid must be, colloquially speaking, “riding” (situated above) these pumps.
These electric pumps are manufactured in two types: single-phase and three-phase, and with single-speed, two-speed, three-speed, and four-speed options.
Due to optimized energy consumption, these electric pumps have an energy efficiency rating of A and B.
This category of electric pumps exists in two main types: with coupling (coupled/dry motor) and glandless (wet rotor/Atatherm).
