Features
- Triplex design for 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 without packing adjustment.
- Special high-density, polished, concentric plungers offer a true wear surface and extended seal life.
- Optional FPM elastomers are available for compatibility with various liquids and temperatures up to 200°F.
- Wet-end can be serviced without entering the crankcase.
- Manifolds are constructed from high-strength forged brass or stainless steel for continuous duty.
- 100% wet seal design enhances service life by allowing pumped liquids to cool and lubricate both sides of the seals.
- Stainless steel valves, seats, and springs provide corrosion resistance, ultimate seating, and extended life.
- Special flushed inlet manifolds on the 1540EC model permit external flush for added cooling with high-temperature liquids and lubrication with low-lubricity liquids.
Important Notes
- All high-pressure systems require a primary pressure regulating device (e.g., regulator, unloader) and a secondary pressure relief device (e.g., pop-off valve, relief valve). Failure to install such relief devices could result in personal injury or damage to the pump or property.
- Always read all CAUTIONS and WARNINGS before commencing service or operation of any high-pressure system.
