CHEM-FEED® Plastic Duplex Skid System

The CHEM-FEED® CFPS-2 Engineered Skid System (For industrial applications) ships fully assembled, simplifying installations and start-ups. CHEM-FEED® CFPS skids are constructed out of strong, light-weight chemical and UV resistant polyethylene and feature leak-free threadless connections. 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® Engineered Skid Systems were designed and engineered using solid modeling tools for superior piping installation and easy component maintenance. Custom engineered universal mounting blocks provide for easy component servicing and replacement.

  • 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:
  • Constructed out of strong Chemical/UV resistant polyethylene
  • Heavy duty wall and floor mounting brackets included
  • Optional chemical feed flowmeter to precisely measure chemical output from the metering pump
  • Optional local wiring connections, easy-to-access power and inputs/outputs
Safety Features:
  • Threaded plug for cleaning and spill diversion in drip containment reservoir
  • Ball valves are vented for operator safety
  • Leak-free threadless connections to ensure leak-free chemical feed
What’s Included:
  • Piping/Unions – Specify from PVC, CPVC, PVDF, or Chem Proline® (PE)
  • Pressure Relief Valve – Protects the system from over-pressurization, 10-150 psi setting range, 150 psi maximum system pressure
  • Check Valve – Protects the user from back-flow during pump maintenance
  • Flow Indicator – Provides a visual indication of chemical movement through the system
  • Inlet Y Strainer – Recommended for Diaphragm Pump systems
Optional components (see product matrix)
  • Calibration Cylinder – Confirm pump output under system conditions. Specify cylinder volumes from 1.6 GPH to 64 GPH.
  • Pulsation Dampener – Protect the system components from pulsation. Recommended for diaphragm pump systems only
  • Pressure Gauge with Guard – Isolate and protect the system pressure gauge. Specify pressure ranges from 0-30 psi, 0-100psi, or 0-200 psi
  • S6A Chemical Flowmeter – Provides 4-20mA and pulse output data to SCADA and to the pump to verify chemical feed
  • Terminal Box: Pumps pre-wired for easy access to all electrical signal wires
  • Electrical Outlet Box: Designed for use in wet, damp, or dry locations
  • Back Pressure Valve – Protects the user from back-flow during pump maintenance
  • Pressure Switch with Guard – Activate or de-activate equipment when pressure in a piping system either rises or falls to a set pressure
