Pump Packing/Mechanical Seal Demonstrator


#280 Pump Packing/Mechanical Seal Trainer, Thumbnail

This unique, multi-use device allows for demonstration and training related to industrial pump sealing systems.

Based on the dimensions of a standard ANSI centrifugal pump and incorporating a clear acrylic seal area, this lightweight demonstrator allows for installation, and testing of a broad variety of mechanical seals and conventional packing systems.

A PVC, representative impeller housing, leak-off taps and provision for vents and drains, allow for introduction of pressurized water to test seals and packing under pressure. Food coloring can be added to allow greater visibility of migration through an improperly packed stuffing box or leaking in a mechanical seal which has been installed incorrectly.

This light-weight, portable, yet realistic training demonstrator will be an excellent addition to any course relating to pump operation, and maintenance.


  • Formed, 7-gauge, steel baseplate with provision for bench-top mounting.
  • Clear acrylic "backhead" and stuffing box, allowing for complete visibility of the seal area, and allowing for installation of many commercially available mechanical seals.

  • Aluminum shaft assembly, incorporating a stainless steel, 1-3/4" shaft sleeve.
  • Aluminum spacer assembly, connecting impeller housing and power-end.
  • Aluminum, simulated power-end, incorporating sleeve bearing and radial ball bearing for pump shaft support.
  • Provision for attaching leak-off tubing or coolant recirculation tubing in the seal area.
  • Quick-disconnect tube fittings at all fill, vent and drain locations.
  • Aluminum lantern ring.
  • Aluminum packing gland.
  • Acrylic replacement packing gland for mechanical seal applications.
  • Handwheel, allowing for shaft rotation.
  • Provision for mounting on the DAC, #905 Electromechanical Bench.
