COMPONENTS & SOLUTIONS FOR FLUID HANDLING

DESCRIPTION

The MTM800 series of cartridge mechanical seals for vertical pumps is one of the products of greater importance. Realized from the diameter 50 up to 500mm (up to 19.7 inches) ensures a sturdiness and a compactness never achieved so far. It can be realized also in a “full split” (MTM850) allowing the installer to be able to intervene on the mechanical seal without disassembling the machine in which it is installed. The pumping ring of the MTM800 seal rotating part is one of the innovations introduced. It ensures a greater distribution of the fluid inside, increasing the thermal disposal of the contact faces. Realized also in Hastelloy, Inconel and Duplex presents a series of accessories to ensure maximum control on the state of the operation of the seal.
