Triplex design offers high efficiency and low pulsation.
Durable high pressure seals are lubricated and cooled by pumped
liquid.
Pre-set Lo-Pressure Seals provide secondary protection against
external leaks and require no packing adjustment.
Optional STHT, FPM and EPDM elastomers for compatibility with
many liquids and temperaturesup to 200°F
Alternate crankshaft strokes offers flexibility with belt, clutch or
direct-drive installation.
