ITT Goulds Pumps
XHD Extra Heavy Duty Lined Slurry Pumps
The Goulds Model XHD is an extra heavy duty lined slurry pump representing the next generation of severe-duty slurry pumping. Developed with CFD analysis and direct customer input, it pairs extra-thick replaceable liners with a quick-change wet end so wear parts are renewed fast and the pump goes back to work.
Product Benefits
- Interchangeable linings: The XHD's defining flexibility is that rubber and metal wear components are interchangeable in the same casing.
- Change strategy, not pumps: If the duty changes, or the first liner choice proves wrong, the plant can switch lining strategy without buying a different pump.
- CFD-refined hydraulics: Hydraulic passages were refined with CFD analysis for high efficiency, and the extra-thick hardened chrome iron liners extend wear life on the metal-lined build.
- Adjustable suction seal: A patented adjustable suction seal ring on metal-lined pumps lets the critical suction-side clearance be reset as it wears, holding efficiency between overhauls.
Where It's Used
- Abrasive mill streams: In pulp and paper service, the XHD handles abrasive streams such as lime slurries, ash slurries and fly ash.
- Severe duties: It is aimed at duties severe enough that wear parts dominate the pump's operating cost.
- Liner life economics: Liner life and the speed of liner replacement are the deciding factors on these services.
Good to Know
- Quick-change cartridge: A quick-change bearing cartridge carries bearing isolators on both end covers, and machined slide rails align shaft and cartridge during reassembly.
- Easy impeller handling: A patented tapered impeller thread eases assembly and alignment, and an impeller release collar is standard on all sizes.
- Sealing options: Shaft sealing offers packing, an expeller or mechanical seals, with a split stuffing box and gland to speed seal maintenance.
- Faster repairs: These details shorten mean time to repair, which on severe slurry duty often matters as much as wear life itself.
