Hanna HNA and HNE are horizontal, single-stage, radially split process pumps. HNA uses foot mounting, while HNE uses centerline support for a different pressure and temperature envelope.

Product details
The detailed product description gives HNA a 2.5 MPa casing-pressure limit and −80 to 180°C temperature range. HNE is listed at 5 MPa and −80 to 450°C. These are separate construction envelopes, not interchangeable ratings for every material or seal combination.
The family covers DN25–400 and 5.5–2,600 m³/h, with head up to 250 m across selections. Replaceable wear rings, a removable rotor assembly, oil-lubricated bearings and seal flushing or cooling options are described. Packing, single mechanical seals and double mechanical seals require a process-specific choice; the support arrangement should be agreed before selecting a detailed curve.
SELECTION NOTES
Specify the operating duty
Provide normal and maximum temperature, inlet pressure, flow and head, liquid composition and density. Confirm HNA or HNE construction, material grade, seal plan and allowable piping loads.
Published limits may describe different configurations within a series. Confirm that the required operating conditions are valid together.
