Centrifugal Pumps
Heavy-duty centrifugal pumps for mud transfer, mixing, charging and general slurry service across drilling and industrial operations.
Centrifugal pumps are the workhorse of every fluids skid — mud mixing, tank-to-tank transfer, mud-cleaner and desilter feed, cooling water, and general utility service. Correctly specified, they run for years with minimal intervention; poorly specified, they cavitate, wash their seals and pull the whole system into unplanned downtime.
Paragon supplies horizontal end-suction and split-case centrifugal pumps in oilfield and industrial configurations, with hard-iron, ductile-iron or 316L wetted parts and a full range of mechanical seal options.
How it works
- 1An electric or hydraulic motor drives an impeller inside a volute casing at constant speed.
- 2Fluid enters the impeller eye axially and is thrown outward by centrifugal force, gaining velocity and pressure as it exits the impeller vanes.
- 3The volute converts velocity into discharge pressure and directs the flow to the discharge flange.
- 4Suction conditions (NPSH available) and impeller geometry determine whether the pump runs stably or cavitates.
Typical specifications
Specifications indicative — actual configuration sized against your specific process.
Typical applications
- Mud mixing and charging on drilling rigs
- Desander / desilter / mud-cleaner feed duty
- Tank-to-tank transfer of drilling and completion fluids
- Slurry transfer in mineral processing and dewatering
- Cooling water, service water and utility duty
Selection factors
Duty point over headline flow
A pump curve is only useful at the actual duty point. Confirm both flow and head at the operating condition, not the peak of the curve — running far off best efficiency point (BEP) wrecks bearings and seals fast.
NPSH available vs required
Cavitation is the single most common cause of centrifugal pump failure. Calculate NPSHa at the actual suction condition and select a pump with meaningful margin (typically NPSHa ≥ NPSHr + 1 m).
Seal selection is not optional
Packed glands are cheap and simple but leak by design. On abrasive or hazardous service, specify a properly sized mechanical seal with a compatible flush plan (API 682 Plan 32 / 53 on the worst duties).
“If a centrifugal pump keeps eating seals, the answer is almost never a better seal — it is NPSH or misalignment. Fix the root cause first.”
