CHEM-FEED® Wall Mount Duplex Skid System

The all-new CHEM-FEED® CFWS-2-M Wall Mount Duplex Skid System (For municipal applications) is designed to be mounted on a wall freeing up valuable floor space. Available in a simplex and duplex chemical feed pump configurations. Pipe material options include PVC, CPVC, PVDF, and Chem Proline® (PE).

An optional SONIC-PRO® Chemical Flow Meter provides accurate measurement of chemical feed and features an isolated 4-20 mA output, process control via configurable solid state relay, and user-configurable flow rate and total set-point triggers.

CHEM-FEED® Wall Mount Skid Systems were designed and engineered using solid modeling tools for superior piping installation and easy component maintenance. Every skid is completely assembled, tested, and shipped directly to you.

  • Straightforward chemical feed skid: easy to order, ready to install, 2-week lead-time
  • Visual flow indicator for visual confirmation that chemical is flowing
  • All installed components are isolated with ball valves for easy maintenance
Superior Design:
  • 2 Year Warranty
  • Constructed out of strong Chemical/UV resistant polyethylene
  • Heavy-duty wall mounting strut channels
  • Optional chemical feed flow meter to precisely measure the chemical output from the metering pump
Safety Features:
  • Ball valves are vented for operator safety
  • Leak-free threadless connections to ensure leak-free chemical feed
Ease of installation and use:
  • Fits through a standard door opening for ease of installation
  • Designed to be mounted on a wall, where space is limited or above a day tank, tote, or barrel
  • 4 sturdy handles for easy transport and ease of installation
What’s Included:
  • Piping/Unions – Specify from PVC, CPVC, PVDF, or Chem Proline® (PE)
  • Calibration Cylinder – Confirm pump output under system conditions. Specify cylinder volumes from 1.6 GPH to 64 GPH (PVC/Glass).
  • Pressure Gauge with Guard – Isolate and protect the system pressure gauge. Specify pressure ranges from 0-30 psi, 0-100psi, or 0-200 psi
  • Flow Indicator – Provides a visual indication of chemical movement through the system
