Diaphragm Metering Pumps

Diaphragm metering pumps are trusted for their dependability, easy maintenance and versatility in a wide range of water conditioning applications. And because the diaphragm is motor-driven, it is cool running and long lasting.

The unique elastomer diaphragm is sealed against the reagent head forming a leak free pumping chamber that is seal-less and extends the life of the pump.

With fewer moving parts and premium construction, Chem-Tech owners enjoy low-maintenance efficiency. Made with chemical resistant materials, the motor and gear shaft are treated with a special lubricant to extend the life of the pump in normal environments.

The feed rate control output is fully adjustable over the entire operating range. And with visible check balls, you can easily see proper operation on the 100/150 series.

100 / 150 Series

  • Feed rates from 3 to 100 gpd (0.47 to 15.76 lph) / Pressures up to 100 psi (7 bar)
  • Bleed Valve Assembly: Aids in the priming and relieves pressure from the discharge line
  • pH Adjustment Applications: Soda Ash, Caustic

Degassing Series

  • Feed rates from 15 to 100 gpd (2.34 to 15.76 lph) / Pressures up to 100 psi (7 bar)
  • Self priming
  • Degass Head Assembly: Top mounted vent valve evacuates gas bubbles for return to the tank to eliminate vapor lock
  • Disinfection Applications: Chlorine, Hydrogen Peroxide, Chemicals that tend to out gas

Peristaltic Pumps: self-priming and off-gas tolerant

Chem-Tech Peristaltic Metering Pumps are self priming and off-gas tolerant, making them the ideal choice for chlorine and similarly volatile chemical applications. The head on a peristaltic pump consists of a piece of tubing and a roller assembly that moves chemicals around the circular head. The engineered composite, three piece roller assembly reduces friction, while allowing a greater load capacity and longer tube life.

Made with all metal gears and housed in a sealed metallic housing, the rugged unit extends the life of the pump and requires lower maintenance. It features a metallic gear box with gasket and the Norprene tubing assembly is the only wetted component within the pump.

The degassing and self-priming Peristaltic Tube is designed with a triple roller assembly that pumps liquid and gas without risking vapor lock. It eliminates the need for a foot valve / anti-siphon.

Select from multiple control configurations — with features and benefits that customers ask for.

The XP Series fixed rate models are simple and straight forward pumps for water conditioning applications where economy and ease-of-use are required. Adjustable Rate models feature 20:1 turndown for enhanced flexibility.

XPV Variable Rate models with LCD display offer simple, intuitive program selections and clearly displays operating parameters. Variable Rate models also allow a variety of choices of input signal types, and onboard timer programs to customize the pump to any application.
