• Standard NBR (Buna-N) seals and o-rings
• Oil-bath crankcase
• Heat treated valves and seals
• Solid ceramic plungers
• Exclusive high-pressure seal design
• Wet ends can be serviced without entering the crankcase
• High-pressure seals are lubricated and cooled by the solution being pumped
• Pre-set low-pressure seals provide secondary protection against external leaks
