The CD1 Chem-Feed Multi-Diaphragm Pump is a positive displacement chemical metering pump that delivers smooth, continuous chemical feed even when injecting chemicals that off-gas, like Peracetic Acid and Sodium Hypochlorite. The cutting-edge Hyperdrive Technology allows for alternating pumping action between two diaphragms: when one diaphragm is in the suction phase, the other is in the discharge, resulting in a smooth chemical feed profile and minimizing the risk of vapor lock. https://www.youtube.com/watch?v=qzZAU8fGzB0&t=75s
The CD1 uses either DiaFlex or Flex-A-Prene diaphragms. DiaFlex diaphragms are guaranteed to last the life of the pump.
Product Overview / Features
- The CD1 pump can deliver 8.50 GPH (32.2 LPH) at O psi, 8.18 GPH at 60 psi, 7.68 GPH at 120 psi, and 7.50 GPH at 150 psi.
- Brushless DC Motor is capable of 2,000:1 Turndown. Can achieve low flows without stroke adjustment.
- “CD1F” Models include simple manual speed adjustment at the pump.
- “CD1V” Models include 4-20mA input and 4-20mA output.
- Integral DFD leak detection.
- Remote Start/Stop via Normally Open or Normally Closed Dry Contact.
- FVS (Flow Verification System) input.
- Control Lockout Feature.
- Wetted parts are PVDF, Aflas, Ceramic (or Teflon), and DiaFlex (or Flex-A-Prene) diaphragms.
- Simple IP67 M12 connectors for communication wiring.
- 2-Year Limited Warranty.
The CD1 is designed to provide smooth, chemical feed for a variety of chemicals and processes. It can reliably pump chemicals that off-gas, such as sodium hypochlorite, peroxide, ammonia, and PAA (peracetic acid).
The smooth flow profile and full diaphragm stroke allow the CD1 to effectively pass gasses without vapor-locking, minimizing the need for re-priming.
The CD1 is constructed of chemical-resistant materials, making it a great choice for aggressive acids and mixed or proprietary chemicals.
Frequently Asked Questions
- How long is the pump expected to last?
The pump is expected to have a lifespan of 6 years. However, with regular maintenance, including cleaning, lubrication, and inspection, the pump can last much longer. Regular maintenance can help to prevent premature failure and extend the lifespan of the pump.Will there be water in the pump when received by the end user? Why?
There may be trace amounts of water in the pump. Every pump is tested with filtered water as part of our quality process.What is the difference between the CD1F and CD1V?
The CD1F and CD1V have the same specifications and performance. The CD1F has only manual speed adjustment, whereas the CD1V also includes 4-20 mA input for speed adjustment and 4-20 mA output for speed feedback.
