Unmatched Power, Extreme Precision! The 700Bar Ultra-High Pressure Manual Hydraulic Calibration Pump Debuts

In heavy industries such as petrochemicals, energy & power, and hydraulic machinery, the extreme reliability and ultra-high precision of pressure measurement are lifelines for ensuring equipment safety and preventing catastrophic failures. Faced with process pressures often reaching hundreds of atmospheres, conventional calibration tools fall short. To address this, Xi'an Xinyi Instrument Technology Co., Ltd. proudly introduces its flagship product—the YHP-70 700Bar Manual Pressure Calibration Pump. Constructed with a full stainless steel body, this hydraulic pressure calibrator, with its astounding 70 MPa (700 Bar) ultra-high pressure generation capability, redefines the limits of portable pressure calibration. It is specifically designed for calibrating high-pressure pressure transmitters, pressure sensors, precision pressure gauges, and providing vacuum/negative pressure calibration, serving as an indispensable "Guardian of Precision" in high-pressure industrial fields.

1. Impressive Coverage of Both Ultra-High Pressure and Vacuum:
   The excellence of the YHP-70 lies in its unparalleled wide range. It can stably generate continuously adjustable pressure from -0.088 MPa (high vacuum) to 70 MPa (ultra-high pressure). This means a single device can perfectly solve the entire series of calibration challenges from vacuum system instruments to ultra-high-pressure hydraulic devices, achieving one-stop coverage from "negative pressure" to "thousand-fold positive pressure." For calibrating critical instruments like hydraulic station pressure sensors, wellhead pressure transmitters, and autoclave pressure gauges, it offers an unprecedented portable solution.

2. Hydraulic Stability and Stainless Steel Resilience:
   Unlike pneumatic pumps, the YHP-70 operates on a hydraulic (oil pressure) principle, using transformer oil as the medium. Hydraulic systems offer inherent advantages of stable pressure, minimal fluctuation, and immense output force, making them particularly suitable for high-precision static pressure calibration. Its core components are precision-manufactured from high-quality stainless steel, ensuring absolute structural safety and long-term durability under ultra-high pressures, fully capable of withstanding harsh industrial environments like oil fields, mines, and field testing sites.

The premier performance of the YHP-70 Manual Pressure Calibration Pump is forged by a series of top-tier technical parameters:

• Industry-Leading Pressure Range: Operating pressure range of -0.088 ~ 70 MPa, equivalent from near absolute vacuum to ultra-high pressure up to 700 Bar, with an exceptionally wide range ratio.

• Stable and Pure Hydraulic Medium: Uses standard No. 25 transformer oil as the pressure transmission medium. It features high cleanliness and good lubricity, effectively protecting the internal chambers of the calibrated instruments from contamination.

• Precise and Reliable Operating Environment: Designed for an operating temperature of 0 ~ 40°C and relative humidity < 100%, ensuring measurement stability and repeatability in various indoor and outdoor conditions.

• Robust and Universal Industrial Interface: Equipped with a standard M20*1.5 threaded connection (export version is 1/2NPT). It can be quickly connected to the vast majority of industrial pressure instruments via high-pressure hoses, offering robustness and excellent leak resistance.

Thanks to its extreme performance, this Stainless Steel Pressure Gauge Calibrator is the preferred calibration choice for the following ultra-high-pressure and high-risk industries:

• Oil & Gas Extraction: Field calibration of drilling blowout preventer control pressure, downhole tool pressure sensors, and high-pressure transmitters at wellheads.

• Chemical & Process Industries: Setting and calibration of ultra-high-pressure gauges and safety valves on high-pressure reactors, polyethylene/ammonia synthesis towers.

• Energy & Power Systems: Calibration of pressure instruments on steam pipelines in thermal power plants, hydraulic hoists in hydropower plants, and auxiliary systems in nuclear power plants.

• Heavy Machinery & Aerospace: Hydraulic system calibration for construction machinery, hydraulic testing for aircraft landing gear, and pressure sources for high-pressure valve test benches in valve factories.

1. No Power Required: Fully manual operation, independent of any electrical or pneumatic power source, truly enabling calibration anytime, anywhere.

2. Easy Pressure Control: Pressure is generated by the reciprocating motion of the handle and can be finely adjusted and stabilized via a built-in fine-adjustment valve.

3. Safety Design: The system incorporates multiple safety pressure relief valves and a rugged pressure-bearing structure, ensuring absolute operator safety even at the extreme pressure of 70 MPa. After calibration, the high-pressure oil in the system can be smoothly released via the pressure relief valve.

Xi'an Xinyi Instrument Technology Co., Ltd. is committed to providing calibration solutions covering the full pressure range. The YHP-70, as a representative of its ultra-high-pressure product line, comes with a two-year warranty and supports OEM/ODM customization services to ensure it perfectly meets the unique needs of special industries.

In an era where industrial equipment continuously advances toward higher parameters and greater capacity, challenging measurement limits means safeguarding the bottom line of safety. The birth of the YHP-70 700Bar Manual Hydraulic Calibration Pump not only fills a market gap for portable ultra-high-pressure field calibration but also brings the precision standards of calibration laboratories to the forefront of production lines.

It acts like a "Pressure Master" of immense power and meticulous care, carrying the might of hydraulics within a stainless steel body, conducting the strictest "physical examinations" for those "pressure sentinels" at the critical nodes of industrial systems. Choosing the YHP-70 means choosing to provide the highest level of reliability assurance for your core high-pressure assets, using unquestionable measurement precision to solidify the foundation of safe production in modern heavy industry.
