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.

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
Communication & Interface:
  • 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. (Included with CD1V only)
Superior Design:
  • 2 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
  • 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
Optional Components Available:
  • Elbow Adapter Kits
    • Elbow Connectors – ½” Male NPT, ½” Hose Barb, ⅜” Tube Compression
    • O-rings – AFLAS, EP
