CD1
CHEM-FEED® Multi-Diaphragm Metering Pump
The CD1 delivers smooth, continuous chemical feed even when injecting fluids that off-gas. Its cutting-edge Hyperdrive® Technology alternates pumping action between two diaphragms, minimizing vapor lock risks.
Exclusive DiaFlex® and Flex-A-Prene® diaphragms offer superior chemical resistance and maximum durability.
The “CD1C” Control model features manual speed control, 4–20 mA input and 4–20 mA output, Remote Start/Stop via Normally Open or Normally Closed dry contact, and FVS (Flow Verification System) input, while the “CD1B” Base model provides manual speed control only with no input/output options.

Features and Benefits
Overview
Key Features
Benefits
- Exclusive Hyperdrive technology allows for smooth chemical feed – Patent Pending
- Dual Diaphragm with full stroke technology will not lose prime, ideal for pumping chemicals that off-gas (Peracetic Acid, Sodium Hypochlorite)
- Can pump chemicals continuously, like a peristaltic pump, without the need for tube assemblies
- Unibody and Unidirectional Cartridge Check Valves reduce parts, simplify maintenance, and ensure proper directional installation.
Communication & Interface
Superior Design
- 2 Year Warranty
- Energy-efficient BLDC motor will not overheat
- Snap-in-place wall and floor mounting bracket – Patent pending
- DiaFlex® diaphragm is designed to last the life of the pump, eliminating the need for expensive rebuild kits – Patented, and covered under the pump’s 2-year warranty.
- 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
- Lockout feature prevents any unwanted tampering – Patent pending
- Display shield to protect controls from harsh environments
