Ram Plate Features and Benefits

  • Neoprene rubber wiper rings: Durable wiper is assembled to the ram plate by 3/4 in (19.1 mm) banding strap that keeps the wiper firmly and securely attached to the plate.
  • Strategically located vent valves: Allow the ram plate to exit the drum in a smooth and trouble-free operation while remaining clean and maintenance-free.
  • Shock-absorbing exhaust restrictors: Maintain smooth exit of the ram plate.
  • Specially designed pump mounting collar: Designed to anchor the pump to the ram plate to assure trouble-free operation of the pumps and the plate. Also allows for quick pump change-out during routine maintenance.
  • Manual bleed valves: Located near the pump inlet to assist in quick priming of the pumps.
  • Vent valve reservoir: Allows compatible solution or water for water-based materials, to cover the vent valve and prevent drying of materials.
