Pulsafeeder Chem-Tech Diaphragm Pumps
Fluid Handlers rely on Chem-Tech pumps for an economical, consistent performance. The key element which differentiates these pumps from other types is the elastomer diaphragm. This diaphragm is sealed against the reagent head forming a seal-less, leak free pumping chamber. The motor is connected to the diaphragm to create the pumping motion.
As the diaphragm moves away from the face of the reagent head, it creates a vacuum which closes the discharge check valve and opens the suction check valve, drawing the pumped fluid into the pumping chamber. As the motor forces the diaphragm toward the face of the reagent head, the suction check valve closes and the discharge check valve opens allowing the liquid to flow out the discharge valve.
Pulsafeeder Chem-Tech Peristaltic Pumps
Peristaltic metering pumps are inherently self priming and off-gas tolerant making the Chem-Tech peristaltic pumps the ideal choice for chlorine and similarly volatile chemical applications.
Fluid Handlers can select from multiple control configurations.
- 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 makes simple, intuitive program selections and clearly displays operating parameters. Variable Rate models also allows a variety of choices of input signal types, and onboard timer programs to customize this pump to any application.
The head on a peristaltic pump consists of a piece of tubing and a roller assembly that moves chemical around the circular head. The engineered composite, three piece roller assembly reduces friction, while allowing a greater load capacity and longer tube life.
