Richter SCK Mechanical Seal Chemical Process Pump - PFA PTFE Lined

Richter SCK Mechanical Seal Chemical Process Pumps

The Richter SCK is a fluoroplastic-lined centrifugal chemical process pump equipped with a high-performance RG4 SiC mechanical seal. Designed for corrosive, toxic, and hazardous fluid applications, the SCK offers PFA, PTFE, or conductive PFA lining with sizes from DN 25 to DN 150, pressure rating PN16, and an operating temperature range of -60°C to +180°C. The highly deflection-resistant stainless steel shaft and grease or oil bath seal lubrication ensure extended seal life and reliable performance.
