PUMP SEAL

How to measure the  compression  for Mechanical Seal of Double Support Centrifugal Pump? Step 1: Measure the distance between bearing box and suspension contact surface and bearing box and bearing skin end face. a. Use a depth rule from the contact plane between the bearing box and the gland to the contact plane between the bearing box and the end face of the bearing skin (e.g.; Distance is 109.4mm minus vernier caliper thickness 4mm=105.4mm). b. Use vernier calipers to measure the contact plane between bearing and gland to the contact plane between bearing box and suspension (e.g.; Distance is 115mm minus depth gauge thickness 5mm=110mm).The number of a is 105.4mm and the number of b is 110mm= the distance between bearing box and suspension contact surface and bearing box and bearing skin end surface is 4.6mm. Step 2: Install the shaft sleeve and moving ring on the shaft. The purpose […]
