Description
The MD1 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 MD1 uses either DiaFlex or Flex-A-Prene diaphragms. DiaFlex diaphragms are guaranteed to last the life of the pump.
Product Overview / Features
- The MD1 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.

Applications
The MD1 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 MD1 to effectively pass gasses without vapor-locking, minimizing the need for re-priming.
The MD1 is constructed of chemical-resistant materials, making it a great choice for aggressive acids and mixed or proprietary chemicals.
FAQs
Frequently Asked Questions
MD1 Introduction
- 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.
