Product Overview
The LNP90K10000PSI is a heavyduty skidmounted liquid nitrogen pump unit designed for onshore oil & gas field operations. It works in conjunction with fracturing spreads and coiled tubing units to perform nitrogen injection, well workover, nitrogen displacement, foam fracturing and other wellservice jobs.
The complete skid integrates USA CS&P triplex highpressure cryogenic reciprocating plunger pump, CS&P centrifugal booster pump, genuine CAT C9.3B 375HP diesel engine, FUNK gear transfer box, exhaust gas wasteheat recovery vaporizer, full stainlesssteel cryogenic piping, MEDCO data acquisition & PLC explosionproof control system. No extra auxiliary burner is required for vaporization, cutting field fuel consumption.
Rated max nitrogen output reaches 90,000 SCFH, minimum adjustable flow 21,000 SCFH at 90% pumping efficiency, maximum working pressure up to 10,000PSI. Discharge nitrogen temperature maintains stable at 15℃21℃ (6070°F). Compact singleskid layout with integral lifting lugs for container or flattruck transportation. Suitable for ambient temperature 0℃ ~ +55℃, working altitude up to 3000 m, capable of dusty mountain and desert oilfield conditions. All instruments adopt international imperialmetric dualunit display, fully compliant with oilfield safety and HSE requirements. Optional 2000gal skidmounted LN₂ storage tank and largecapacity 15000gal bulk liquid nitrogen tank are available as auxiliary packages.

Core Product Advantages
WasteHeat Recovery Vaporization, EnergySaving Operation
Adopts CS&P exhaust wasteheat recovery vaporizer, reuses hightemperature exhaust heat from CAT C9.3B engine to vaporize liquid nitrogen. No separate fuelburning heater required. Output nitrogen temperature stably held between 1521℃, prevents cryogenic pipeline frostcracking and significantly reduces field fuel operating cost.Imported CS&P TwoStage Cryogenic Pumping System
Primary CS&P hydraulic centrifugal booster pump provides stable liquidnitrogen feed pressure for downstream triplex plunger pump. Secondary CS&P 3ICP100 triplex reciprocating pump delivers max 10,000PSI highpressure nitrogen gas. Wide speedadjustment range 601200 RPM, covers smallvolume welltesting up to largescale nitrogen fracturing jobs. Equipped with overpressure & lowtemperature autoshutdown safety interlock protection.CAT C9.3B HeavyDuty Diesel Power Pack
Genuine CAT C9.3B 375HP turbo diesel engine with airmotor starting system, explosionproof electrical system and sparkarrestor silencer. Matched FUNK multioutput gear box distributes independent power to triplex pump, booster pump and auxiliary hydraulic circuits. Watercooled radiator system guarantees stable fullload performance up to +55℃ hightemperature desert conditions.HighGrade Cryogenic & HighPressure Manifold Assembly
All lowtemperature suction & return pipelines use 300series stainless steel. Highpressure manifold adopts FMC 2" FIG1502 union fittings, Parker AE safety relief valves, flexible transition joints for coldend connections. All high/lowpressure discharge outlets are safely oriented; thermal/coldinjury protective guards are fitted on all cryogenic and hot components.ExplosionProof MEDCOPLC Intelligent Control System
Fully stainlesssteel explosionproof control cabinet with touchscreen HMI, MEDCO data acquisition software. Realtime monitoring for engine parameters, booster speed, nitrogen flow, outlet pressure & temperature, pump lubrication status. Supports data recording, curve display, export, and hardwired interlock emergencystop signal communication with coiled tubing unit for joint operation safety. Complete local manual override switches for onsite operation.Integrated HeavyDuty SkidMounted Layout
Whole unit preassembled on heavy steel skid with integral lifting lugs. Compact dimension 4.5×2.5×2.5 m for standard container or flattruck shipping. Prerouted piping & cabling minimize field assembly work. Fullset 24V explosionproof floodlights for roundtheclock nighttime wellsite operations.HarshEnvironment MarineGrade AntiCorrosion Treatment
