SSP Pumps has further enhanced its product range in providing their customers with Atex certified rotary lobe pumps for use in potentially explosive atmospheres under the Atex Directive 94/9/EC Group II, Categories 2 and 3, Gas and Dust. In order to meet Atex compliance one important consideration for a rotary lobe pump is the primary seal. Here, the concern is for monitoring seal performance parameters, in particular the risk of mechanical seal faces becoming hot under certain conditions.
The pumps offer the solution with different levels of monitoring to suit application demands. The ultimate solution is pumps fitted with double flushed mechanical seals and sealant system to include monitoring equipment to measure pressure, flow and temperature. Other solutions include pumps fitted with either single unflushed or double flushed mechanical seals complete with a thermocouple to measure temperature, suitable for customers to connect to their own monitoring instrumentation. The thermocouple is embedded into the seal face ensuring accurate temperature differential monitoring. Single mechanical seals without thermocouple may be supplied so that customers can make their own arrangement for monitoring to ensure that seals do not run dry and the process temperature does not exceed the values for the defined application. The pump seal specified would be dependent upon pumped media and application.
