MD1
CHEM-FEED® Multi-Diaphragm Metering Pump
The MD1 delivers smooth, continuous chemical feed even when injecting fluids that off-gas. Its cutting-edge Hyperdrive Technology alternates pumping action between two diaphragms, minimizing pulsation and risk of vapor lock. Now, with the standard Automatic Degassing Valve (ADV) System on our MD1 pumps, we’ve further reduced vapor lock risks and eliminated the need for external degassing components.
The exclusive DiaFlex® Diaphragms last the life of the pump, saving on rebuild costs.

- Can pump chemicals continuously, like a peristaltic pump, without the need for tube assemblies
Communication & Interface:
- Input: 4-20mA external control
- Input: Remote Start/Stop: Non-powered dry contact closure for remote start/stop
- Input: Compatible with Flow Verification Sensors S6A and Micro-Flo
- Output: Alarm relay 250V / 3A
- Output: Motor On / Off single solid-state
- SCADA Inputs/Outputs include: 4-20mA.
Superior Design:
- 5 Year Warranty
- Energy-efficient BLDC motor will not overheat
- Snap-in-place wall and floor mounting bracket – Patent pending
- DiaFlex® diaphragm design will last the life of the pump, eliminates the need for expensive rebuild kits – Patented
- The Automatic Degassing Valve (ADV) System technology eliminates vapor lock risks and the need for external degassing components.
- Manifold design allows for multiple configuration possibilities – suction and discharge ports can be positioned on the left and right side of the pump
Safety Features:
- Diaphragm Failure Detection (DFD) Senses diaphragm rupture by detecting chemical in the pump head. No false triggering – Patented
