The Economy Series Pot Feeders, Bypass Feeders, and Shot Feeders, at web competitive pricing, are ideal for the aftermarket where cost considerations are paramount.

  • Safety Bar Closure™  is easy to open with a small adjustable wrench at very low torque.  The Griswold Safety Bar Closure™ is inherently safe.  If accidently opened under pressure, the safety bar & lid are securely restrained. This makes it is impossible for the lid to fly off and cause damage or injury.
  • The fill opening is a full 4 inch in diameter. Adding chemical products without spillage is easy.
  • Powder coat finish.
  • Operating Limits: 200 psig at 200°F.
  • The feeder can serve as a filter feeder simply by adding our stainless steel basket and filter bag.
  • The feeder can become a cartridge filter feeder simply by adding our cartridge filter assembly.
  • The short installation time for a Griswold ES feeder is unmatched in the industry:
    • The low torque required to open & close the Safety Bar ClosureTM eliminates the need to anchor the ES feeder to the floor.
    • The inlet and outlet ¾” valve package (VP-75) is unique in the industry. Each valve body has an additional valve for venting or draining.  The VP-75 simplifies installation & reduces the number of installation fittings and joints.  A typical installation using standard ball valves will require 4 valves, 10 fittings, 2 unions, and 16 joints.  Use of the VP-75 requires just 2 valves, no fittings, no unions, and 2 joints.  This saves about $300 in time and material for each installation.
