Description
The CAMTOP Триплексный насос Гидравлическая часть В сборе is a heavy-duty, three-cylinder reciprocating fluid-end module engineered for oil & gas well service applications including cementing, acidizing, fracturing and well-servicing mud circulation. The bolt-on fluid-end design accepts forged fluid-end bodies, plunger packing assemblies and the industry’s most field-serviceable valve cover geometry, allowing operators to swap suction and delivery valve kits without disturbing the manifold or crankshaft alignment.
This fluid end converts the rotary motion of the pump’s power end (crankshaft, connecting rods, crossheads) into reciprocating linear motion through three plungers, charging the suction manifold on each intake stroke and discharging pressurized fluid through the delivery manifold on each compression stroke. The CAMTOP design consolidates the Suction Манифольд, Delivery Манифольд В сборе, three Fluid-End Bodies, three Suction-Клапан Supports and three Клапан Крышка Assemblies into a single, fully interchangeable skid module that can be lifted, transported and replaced as a complete unit — a major advantage during remote operations where downtime is measured in thousands of dollars per hour.
Every fluid-end component shown in the BOM below is independently replaceable: from the delivery valve guide (P/N 01910943) to the spring-loaded valve insert (P/N 40630042), every wear-surface and sealing element uses standardized part numbers so operators can keep a small inventory of Клапан Комплект P/N 40390711 and Delivery Манифольд В сборе P/N 01923350 for rapid turnaround in the field. CAMTOP fluid-end assemblies are built to API 7K design standards and are fully compatible with the popular F-500 / F-800 / F-1300 / F-1600 triplex pump platforms.

Key Features
- API 7K-Compliant Гидравлическая часть — Designed and manufactured to API Specification 7K for drilling and well-servicing fluid-end assemblies, with full material traceability and pressure-test certification.
- 3-Цилиндр Reciprocating Design — Three precision-machined Fluid-End Bodies (P/N 01921761) deliver smooth, low-pulsation flow ideal for sensitive downhole tools and cementing operations.
- Болт-On, Field-Serviceable Architecture — Every suction and delivery valve cover is retained by studs (P/N 01921766 / 01921767 / 01921768) and accessed through the manifold — no torching, no specialised tools, no shaft alignment disturbance.
- Complete Suction Манифольд (P/N 01921874) — Single-piece stainless-steel suction distribution manifold with three integrated Suction-Клапан Supports (P/N 01921792); eliminates the suction-side dead-leg that causes cavitation in inferior designs.
- Replaceable Delivery Манифольд В сборе (P/N 01923350) — One-piece forged delivery manifold with built-in volume chamber to dampen pressure pulsation; replaceable as a single unit for rapid fluid-end swap.
- Standardized Клапан Комплект (P/N 40390711) — Six sets of complete valve kits per fluid-end keeps three spare sets on the rig and one in the warehouse; includes Клапан, Клапан Седло, Пружина, Клапан Insert and Пружина — all drop-in interchangeable.
- Bronze Клапан Guide (P/N 01910943, 3 required) — Precision-cast bronze delivery-valve guides provide wear-resistant seat alignment and extend valve life in abrasive fracturing slurries.
- Race / Plug (P/N 01921762 / 01921763) — Hardened alloy race and tapered plug hold the valve seat concentric during pressure transients up to 7,500 psi operating surges.
- Bushing (P/N 01911079) — Six oil-impregnated bushings absorb side-load on the plunger and reduce wear on the fluid-end cylinder bore.
- Mirror-Polished Цилиндр Bores — Each fluid-end body bore is honed to within 8 Ra micro-inch to minimise plunger-packing wear and extend fluid-end service intervals.
- Кованый, Heat-Treated Construction — All pressure-containing parts are forged from alloy steel (4140 / 4340 grade), quenched and tempered to API 7K Charpy impact requirements at -20°C.
- Modular Skid Integration — Compact envelope accepts standard mud-pump skid bases and shares bolt patterns with the most popular 500-, 800-, 1,300- and 1,600-HP triplex pump geometries in service today.
- Pressure-Tested to 1.5× Working Pressure — Every CAMTOP fluid-end assembly is hydrostatically tested at 1.5 times the rated working pressure before shipment, with full test certificate supplied.
- Recommended Spares Package Available — CAMTOP offers a pre-packaged three-year spares kit (valves, seats, packings, plugs, studs) matched to your fluid-end serial number.
