NV-2

Description

Mechanical seal type NV – 2 is very similar to seal type NV – 1. The main difference is single spring instead of multiple springs. Reason is usage in high viscous media or media containing solids. Mechanical seal design with single spring prevents sticking and blocking of small multiple springs. Seal is very easy and cheap to repair.
