Gland Service Control Systems

The Gland Service Regulator (GSR) Valve is a self-regulating Valve. Each Slurry Pump in the Network or series train has its own dedicated GSR Control Unit. In this manner we provide distributed Gland Service Regulation, minimizing the failure of entire network/train in-case of a singular failure.

The GSR Valve utilizes a pressure differential between the slurry pump discharge pressure, and the incoming unregulated gland service to; automatically regulate the Gland Service, such that:

• The attached stuffing box receives the required Gland Service Flow;
• The attached stuffing box receives approximately 100 kPa of pressure above the Slurry Pump Discharge Pressure.

This regulation of pressure and flow into the stuffing box occurs automatically when system dynamics change. These changes could be due to:

• Change in the Specific Gravity (SG) of the slurry;
• Change in the Operative order of slurry pumps in a given slurry train;
• Change in the Operative speed of slurry pump through a Variable Speed Drive (VSD).
