A unique, multi-purpose device allowing 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 moderate pressure. Food coloring can be added to allow greater visibility of migration through an improperly packed stuffing box or leakage of a mechanical seal which has been installed incorrectly.
7-gauge, formed-steel baseplate with provision for bench-top mounting, and mounting related workstation products.
Clear acrylic “backhead” and stuffing box, allowing for complete visibility of the seal area, and allowing for installation of many commercially-available mechanical seals.
PVC, simulated impeller housing with water inlet, vent and drain.
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 representative pump shaft support and rotation.
Provision for attaching leak-off tubing or coolant re-circulation 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 bench, workstation and display products.
Packaging for shipment via motor freight.
