AKS-P8018A Desktop Hydraulic Pressure Pump

Overview

The AKS-P8018A Desktop Hydraulic Pressure Pump is a precision-engineered, benchtop pressure generation system designed for high-accuracy calibration and verification of pressure instrumentation in metrology laboratories and industrial QA/QC environments. It operates on the principle of manual hydraulic amplification via a dual-stage lever mechanism—combining coarse pre-pressurization with fine micrometer-controlled adjustment—to deliver stable, repeatable, and contamination-resistant pressure outputs across its full 0–100 MPa range. Unlike pneumatic pumps, this oil-based system eliminates compressibility effects and thermal drift associated with gas media, making it especially suitable for calibrating high-range pressure transducers, deadweight testers, digital pressure gauges, and safety-critical pressure switches where long-term stability and minimal hysteresis are mandatory. The unit complies with fundamental requirements of ISO/IEC 17025 for calibration laboratory competence and supports traceable pressure generation in accordance with ASTM E74, EN 837-1, and JJG 52–2013 (Chinese national metrology regulation for pressure gauges).

Key Features

• Integrated CNC-machined monolithic baseplate ensures mechanical rigidity, minimizes vibration-induced pressure fluctuations, and reduces potential leak paths by eliminating redundant tubing connections.
• Patented lever-assisted pre-pressurization architecture enables rapid attainment of target pressure (e.g., >60 MPa within 30 seconds), followed by ultra-fine pressure tuning at 0.1 kPa resolution using a calibrated micrometer screw.
• Dual-mode operation: default closed-loop recirculating mode maintains fluid cleanliness; optional non-recirculating mode—activated via included modular fittings—bypasses the internal reservoir to isolate the test circuit, mitigating contamination risk during extended calibration sessions.
• P816C synthetic hydraulic oil—low volatility, high viscosity index, and oxidation-stable—is factory-filled and certified for compatibility with stainless steel, FKM, and PTFE wetted materials per ASTM D4690 and ISO 6743-4.
• M20×1.5 female quick-connect ports (3×) support simultaneous connection to reference standard, device under test (DUT), and vent/bleed line—enabling three-port differential or gauge/vacuum referencing configurations.

Sample Compatibility & Compliance

The AKS-P8018A is compatible with all pressure instruments rated up to 100 MPa that accept oil-compatible media and feature M20×1.5 male threaded inputs. This includes analog and digital pressure transmitters (4–20 mA, HART, RS485), piston-type pressure gauges, strain-gauge-based sensors, and piezoresistive modules. It meets structural integrity and sealing performance criteria defined in EN 13480-3 (metallic industrial piping) and ASME B31.1 (power piping) for static pressure testing applications. When used in conjunction with NIST-traceable reference standards, the system supports compliance with FDA 21 CFR Part 11 (electronic records/signatures) when integrated into validated calibration workflows with audit-trail-enabled software.

Software & Data Management

While the AKS-P8018A operates as a standalone manual pump, it is fully interoperable with third-party calibration management platforms including MET/CAL®, DPAC, and LabVIEW-based DAQ systems via optional analog voltage output (0–10 V) or RS232 interface modules (sold separately). Real-time pressure feedback from external digital manometers can be logged alongside operator inputs, environmental conditions (temperature/humidity), and instrument IDs to generate ISO/IEC 17025-compliant calibration certificates. All configuration settings, usage logs, and maintenance history—including oil change intervals and seal replacement dates—are retained locally on an embedded EEPROM for GLP/GMP audit readiness.

Applications

• Primary and secondary calibration of pressure standards in accredited metrology labs.
• Factory acceptance testing (FAT) of high-pressure hydraulic components such as fuel injection rails, accumulator vessels, and valve actuators.
• Verification of overpressure protection devices (e.g., relief valves, rupture discs) per API RP 520 and PED 2014/68/EU.
• Research applications involving viscoelastic fluid characterization, where controlled hydrostatic loading is required for rheological sample conditioning.
• Supporting inter-laboratory comparison exercises organized under CIPM MRA signatory frameworks.

FAQ

What is the maximum allowable working pressure for the AKS-P8018A?

The rated maximum pressure is 100 MPa at 23 °C ambient temperature. Operation above 80 MPa requires pre-conditioning of the P816C oil to ≥25 °C to ensure optimal viscosity and seal lubrication.
Can the pump be used with water-glycol or other non-P816C fluids?

No. Substitution of hydraulic medium voids warranty and compromises seal life and pressure stability. Only P816C oil—supplied with each unit and available as OEM refill kit (P/N AKS-OIL-P816C-1L)—is approved for use.
Is the AKS-P8018A suitable for vacuum generation?

No. This is a unidirectional hydraulic pump designed exclusively for positive pressure generation. For vacuum or compound-range applications, refer to the AKS-P8015B or AKS-P8015C pneumatic models.
How often should the P816C oil be replaced?

Under normal laboratory use (≤500 cycles/month), oil replacement is recommended every 18 months or after 2,000 operating hours—whichever occurs first—as verified by kinematic viscosity testing per ASTM D445.
Does the unit include a certificate of conformance?

Yes. Each AKS-P8018A ships with a Factory Conformance Certificate stating serial-numbered verification against master pressure standard (±0.02% FS), mechanical inspection report, and material compliance documentation (RoHS, REACH, PFAS-free declaration).
