Description
The MD3S 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.
The MD3S uses either DiaFlex® or Flex-A-Prene® diaphragms. DiaFlex® diaphragms are guaranteed to last the life of the pump.

Applications
The MD3S pump 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), as well as a variety of other chemicals.
The smooth flow profile and full diaphragm stroke allow the MD3S to effectively pass gasses without vapor-locking, minimizing the need for re-priming.
The MD3S pump is constructed of chemical-resistant materials, making it an excellent choice for aggressive acids and mixed or proprietary chemicals.

FAQs
Frequently Asked Questions
MD3S Introduction
- What are best application for this pump?
The MD3 delivers smooth, continuous chemical feed even when injecting chemicals that off-gas like Peracetic Acid and Sodium Hypochlorite. When high feed rates and high pressure conditions are required the MD3 is a good choice.
What is hyper drive technology?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 chance of vapor lock and loss of prime.
