Eclipse Model 12

up to 3.5 gpm (13.2 lpm)
up to 150 psi (10 bar)
up to 200°F(93°C) with deration

The Eclipse represents a dramatic advance in pump technology. Combining proven design principles with patented features, our pumps are safe, simple, and reliable. Structurally rugged with corrosion-resistant materials, Eclipse is an ideal fit for many corrosive liquids. From acids to bases, we cover the entire pH scale.

The innovative technology behind Eclipse supports its ability to handle the most corrosive chemicals with a simple-to-service, front pull-out design. Eclipse is available with wetted components in completely non-metallic construction. This ensures corrosion resistance over a wide range of chemicals and process conditions. These pumps are magnetically driven to eliminate mechanical seal wear and leaks associated with rotating seals. The patented bearing design promotes constant lubrication.

Product Options
  • Bearing flush
Back Pressure Valves
KOP Kits
Pressure Gauges
  • All wetted components are completely non-metallic, not lined
  • Pump housings and gears are made of engineered composites, magnetically driven, and require no mechanical seals
  • Zero leakage, no emissions of hazardous or regulated chemicals
  • Fewer parts and material options means simplified ordering and inventory
  • Front pull-out design – makes for easy service and maintenance in place
  • Pre-defined KOPkits® allow for easy ordering and kitting of all necessary parts to bring the pump back to factory performance
  • Engineered composite fluoropolymer provide superior chemical resistance, lighter weight, shorter lead-times
  • Pump is bidirectional-can be operated in either direction
  • Modular design allows for the pump ports to be mounted in 45° increments (to a full 360°, vertical, horizontal, or any configuration imaginable)
