Pumping Equipment

Reciprocating positive-displacement pumps, typically triplex or duplex, that circulate drilling fluid during drilling. Built as a power end and a replaceable fluid end, with consumable parts such as liners, pistons, valves, and seats.

Gas-charged or appendage vessels installed on the discharge (and sometimes suction) of reciprocating pumps to absorb the pressure pulses produced by each plunger stroke. They smooth flow, reduce piping vibration and fatigue, and protect instruments and downstream equipment.

Very high-pressure, high-horsepower reciprocating plunger pumps used in hydraulic fracturing to inject fluid and proppant into the formation. Often skid- or trailer-mounted in large horsepower ratings.

Spring- or pilot-loaded valves that maintain a set minimum pressure on the pump discharge to ensure stable flow and accurate dosing. They are common on chemical injection and metering pump systems to prevent siphoning and flooding of the pump.

High-pressure plunger or triplex pumps used to mix and place cement slurry into the wellbore for zonal isolation and casing support. Part of cementing equipment spreads on land and offshore.

Compact pulsation-control devices fitted on the pump suction line to dampen acceleration head and inlet pressure swings. They protect against cavitation and improve volumetric efficiency on positive-displacement pumps.

Rotodynamic pumps that use a rotating impeller to move fluid, used for transfer, water, and process duty. Process units in oil and gas service are commonly built to API Standard 610, including between-bearing and magnetic-drive configurations.

Pressure-relief devices that open at a preset pressure to protect the pump, fluid end, and piping from overpressure when a discharge line is blocked. Sizing and selection follow API 520/521 practice for the duty.

Components such as packing flush systems, cooling jackets, fan-cooled lube coolers, and circulation lines that remove heat from packing, stuffing boxes, and the power end. They control operating temperature to protect seals, bearings, and lubricant.

Reciprocating positive-displacement pumps using plungers and packing to develop high discharge pressure for jetting, washing, testing, and injection. Rely on high-pressure seals at the fluid end.

Flexible connectors, expansion joints, and pipe supports that decouple the pump from rigid piping to reduce transmitted vibration. They lower fatigue stress on welds, flanges, and adjacent equipment.

Small metering pumps, often plunger or diaphragm type, that inject precise, controllable rates of inhibitors, scavengers, and other chemicals into wells and process streams.

Rotary positive-displacement pumps that trap fluid between meshing gears or rotating lobes to deliver smooth, metered flow. Used for transfer of viscous fluids, lubricants, and chemicals.

Accessories that maintain lubrication and pressure containment, including packing sets, lube oil pumps, and seal flush kits for the power and fluid ends. They keep the pump within its rated leakage and wear limits.

Diaphragm pumps use a flexing membrane to move fluid without dynamic seals, suited to abrasive or hazardous media; multiphase pumps move mixed gas-liquid produced fluids without prior separation.
