The Sharples P-3000 is a 14-inch bowl, two-phase horizontal decanter centrifuge generating 3,150 Gs at 4,000 RPM for wastewater sludge dewatering and industrial separation. Dolphin Centrifuge provides parts, rebuilds, and repair from Warren, Michigan.
About the Sharples P-3000
The Sharples P-3000 is a classic industrial horizontal decanter centrifuge that established itself as a workhorse in wastewater treatment, chemical processing, and industrial separation applications over many decades. The Sharples brand was acquired by Alfa Laval, and the P-3000 is now maintained and supported within the Alfa Laval service network — though many plants continue to operate original Sharples-branded units.
Dolphin Centrifuge has extensive experience with the P-3000 platform. We maintain a parts inventory for this model, perform complete mechanical rebuilds, and provide repair and refurbishment services to extend the service life of P-3000 units currently in operation. Whether you need a replacement scroll assembly, bowl inspection, bearing replacement, or a complete rebuild, our team can support your P-3000.

Frequently Asked Questions
+ Can Dolphin Centrifuge still get parts for the Sharples P-3000?
Yes. Dolphin Centrifuge maintains parts inventory for the Sharples P-3000, including scroll assemblies, bearings, seals, and wear components. As the P-3000 is now part of the Alfa Laval portfolio, parts are sourced through both OEM and aftermarket channels.
+ How long does a Sharples P-3000 rebuild take?
A complete P-3000 mechanical rebuild typically takes 2–4 weeks depending on the scope of work — bowl inspection, scroll reconditioning, bearing replacement, gearbox overhaul, and seal replacement. Dolphin Centrifuge provides a detailed timeline after initial inspection.
+ Should I rebuild my P-3000 or upgrade to a newer decanter?
It depends on the unit's condition, age, and available budget. A rebuild extends service life at a fraction of replacement cost when the bowl and main structure are sound. If the bowl is cracked or corrosion is extensive, upgrading to a current-generation Alfa Laval decanter may be more cost-effective. Dolphin Centrifuge can provide a comparative analysis.
+ What is the throughput capacity of the Sharples P-3000 for wastewater sludge?
The Sharples P-3000 is rated at 25 GPM for municipal sludge thickening. Actual capacity varies by sludge type, solids concentration, and polymer dosing. The P-3000 generates 3,150 Gs at 4,000 RPM and is suited to applications requiring a compact decanter with moderate throughput.
+ Does Dolphin Centrifuge provide rental decanters while a P-3000 is being rebuilt?
Yes. Dolphin Centrifuge offers decanter centrifuge rental units to cover production gaps during rebuild periods. Rental units can typically be delivered within one to two weeks. Contact us at (248) 522-2573 to check current rental availability for your capacity requirements.
