The SLR mechanical seal regulating device is a quick-push flow and pressure sight-glass flushing unit with a flow range of 0–15 L/min, a pressure range of 0–0.6 MPa, a 1/2" connection and a POK/aluminium alloy body. When flow or pressure rises above or falls below the set value, it automatically breaks the machine control circuit, protecting the mechanical seal from dry friction and over-pressure and considerably extending seal life.
