May 15, 2017 · equipment condition: mechanical seals typically require equipment to be in good condition to operate reliably. this includes shaft finish, pump/driver alignment, cavitation, and vibration. radial/axial motion and misalignment: most mechanical seals tolerate very little radial movement or misalignment, and little to no axial movement. if the shaft is often moved axially, such as with many
Sep 17, 2014 · mechanical seals are leakage control devices, which are found on rotating equipment such as pumps and mixers to prevent the leakage of liquids and gases from escaping into the environment. figure 1 above shows a typical centrifugal pump, which highlights its constituent parts, including the mechanical seal.
Sep 26, 2010 · this double-mechanical seal configuration consists of two independent seals mounted within a seal chamber outside the pump, which is flushed with an independent water supply at a flowrate of approximately two to four gallons per hour (minimum) and a pressure slightly higher than the maximum expected operating pressure of the pumped solution (figure 3).
In the case of mechanical seal (assuming single mechanical seal) the product loss will be not more than 1 litres for a year. power consumption. the amount of power required to drive a mechanical seal is very less compare the pump having gland packing.
