Product Detailed Description

YALAN TB1, TB1F and TB2 Ready-fitted Mechanical Seals for AHLSTAR Pumps

Structural Features: The ready-fitted seals are designed as an organic part of certain centrifugal pump types without any extra components to get as much space between the seal and casing cover as possible for maximizing reliable operation. The seal is fixed on the shaft without extra components such as shaft sleeve to get optimal material wall thickness for highly reliable operation. The single seal has been designed so that any pressure variations or dropouts of the pumped liquid do not open the seal faces. The double seal has been designed so that any pressure variations or dropouts either on the side of the pumped liquid or sealing liquid do not open the seal faces. The seal faces do not open in the case of vacuum pressure, either. Due to the simple design of the ready-fitted seal, the cost of the seal is much lower than the cost of cartridge mechanical seals.

Industrial Standards: Enterprise Standard

Scopes of Application: TB1, TB1F and TB2 ready-fitted mechanical seals are designed for the seal chamber of the standard gland packing casing cover and for the standard shaft without extra shaft sleeve, for different pump types like AHLSTAR process pump range types A, APP, NPP, WPP.
