Taper Spring Mechanical Seals :

Mechanical seal with conical helical spring unbalanced with 'O' Ring as secondary sealing member. Conical helical spring seal is a direction dependent seal. The view from seal face of rotating parts of the seal, clockwise rotating shaft require right hand springs and shafts anti-clockwise direction require left hand springs. Seal face materials and elastomers can be selected from various material for a wide range of applications. The torque on the face is transmitted by means of conical helical spring. The direction of rotation is viewed from the drive end of shaft. The mounting of the seal on the shaft is easier by means of twisting action in the same direction of spring coiling will tend the spring to open. Helical springs are insensitive to small amount of medium contamination.
