Wofulong IHF is a horizontal fluoroplastic centrifugal pump family for chemically compatible process liquids. The catalog describes a metal-supported fluoroplastic construction and a mechanically sealed shaft arrangement.
The lining and wetted components must be selected against the liquid composition, concentration and temperature. Fluoroplastic construction alone does not establish compatibility with every chemical or abrasive mixture. The product description discusses shaft rigidity and a short cantilever as structural features of the coupled pump arrangement.
The published family includes DN25–250 sizes and nominal 1,450 or 2,900 r/min selections, with a listed working-pressure limit of 1.6 MPa. These values describe the range rather than one installed assembly. Selection requires the individual curve, material schedule and seal specification, especially where suction pressure contributes to casing pressure.
SELECTION NOTES
Specify the operating duty
Provide chemical composition and concentration, flow, head, suction pressure, temperature and solids content. Confirm lining material, seal faces and elastomers, speed and the selected duty curve.
Published limits may describe different configurations within a series. Confirm that the required operating conditions are valid together.
