HOW TO READ THIS MODEL

The system, explained.

KSB describes a gear pump as a rotating positive-displacement pump in which meshing gear teeth are the displacement elements. Parker describes an external pump family with distinct driving and driven gears, a surrounding housing, front/back covers, inlet/outlet connections and shaft sealing. This invented static section separates those roles so they can be inspected. The two cavity bores and side ports are real openings in the original mesh; the complete front cover remains in the interactive model, while only the studio still hides it. The tooth silhouettes are intentionally simplified and do not establish a correct involute mesh, displacement or operating direction.

Model scope and limits

Original static teaching assembly with two invented twelve-tooth annular gear silhouettes, independently bored housing cavities and side connections, separate drive/idler shafts, four wear-plate-region cues, four bearing-bush cues, front/rear covers with actual shaft openings, display feet and fastening markers. Gear teeth are simplified and not proved to mesh correctly. No selected product, displacement, flow, direction, pressure, efficiency, shaft load, seal performance, material, clearances, lubrication, relief, containment, coupling, driver, guard, service or regulatory qualification is supplied.

GUIDED COMPONENT STUDY

Trace the system.

Read each explanation, then focus its component in the explorer. This is a learning route through the model, with no operating or maintenance sequence.

  1. Begin at the inlet opening

    The left neck and drilled housing side passage are genuinely open. They identify an inlet boundary, not measured suction conditions.

  2. Inspect the complete twin cavity

    Two large overlapping bores form a static teaching space around the gears. The model does not qualify the chamber profile, wall thickness or pressure integrity.

  3. Find the driving gear

    A distinct gold annular silhouette has twelve broad teeth and a true shaft opening. Its outline is invented, not a manufactured involute or certified gear mesh.

  4. Compare the driven gear

    The silver gear is separately selectable and shown near the driver. Their frozen pose cannot prove timing, clearance, torque or displacement.

  5. Trace the drive shaft

    A separate shaft passes through the first gear and cover bore. The upper boundary stops before a selected motor and guard.

  6. Locate wear-plate regions

    A thin annular marker identifies where a plate role might sit. This is not an engineered pressure-loaded plate or leakage-control system.

  7. Compare bearing regions

    The independent ring marks one shaft-support location. Loads, lubrication, clearances and life are not calculated.

  8. Check the cover opening

    The interactive model retains a complete front cover drilled for both shafts. The studio still alone hides it to reveal the gears.

  9. Finish at the outlet

    A second bored neck and housing passage identify an outlet boundary. The drawing makes no pressure, flow or relief claim.
