York Instrument CPP700-H & CPP1000-H Handheld Hydraulic Test Pumps

Overview

The York Instrument CPP700-H and CPP1000-H are precision-engineered handheld hydraulic test pumps designed for field and workshop calibration, leak testing, and pressure verification of high-pressure instrumentation. These manually operated pumps utilize a dual-stage piston architecture to generate stable, controllable pressure outputs up to 70 MPa (CPP700-H) and 100 MPa (CPP1000-H), respectively. Their operation is based on positive displacement principles: coarse pressure build-up is achieved via a large-diameter primary piston, while fine pressure adjustment—critical for metrological accuracy—is executed using a smaller secondary piston with micrometer-style control. This two-stage mechanism ensures minimal hysteresis, high repeatability (< ±0.05% FS per cycle under controlled conditions), and low operator fatigue during extended use. The units comply with fundamental requirements of ISO 4064-3 (water meter testing), EN 837-1 (pressure gauge accuracy classes), and support traceable calibration workflows aligned with ISO/IEC 17025–accredited laboratories.

Key Features

• Compact, ergonomic aluminum alloy housing with integrated carrying handle and non-slip rubber grip for one-handed operation in confined or elevated locations.
• Dual-mode pressure generation: quick-fill mode for rapid pressurization; precision mode for sub-bar resolution adjustments—enabled by an integrated toggle switch located on the pump body.
• Direct-mount reference gauge interface: standard 1/4″ NPT female port on top allows secure, zero-leak mounting of certified reference pressure gauges or digital calibrators (e.g., Fluke 754, Druck DPI 620).
• Test port equipped with G¼” internal thread (DIN 3852-E) for universal compatibility with industrial pressure sensors, transmitters, switches, and analog gauges.
• CPP700-H includes the Minimess® 1620 quick-connect system as standard—enabling tool-free, contamination-resistant connection to test devices without disassembly or seal replacement.
• Self-bleeding, multi-stage filtration system minimizes particulate ingress into the hydraulic circuit; compatible with ISO VG 22 mineral oil and synthetic ester-based calibration fluids.

Sample Compatibility & Compliance

These pumps are validated for use with pressure instruments across Class 0.1 to Class 1.6 accuracy grades per EN 837-1 and ASME B40.100. They support wetted material compatibility with stainless steel (316 SS), FKM elastomers, and hardened tool steel components—ensuring long-term stability when used with hydrocarbon-based, glycol, or water-glycol test media. All models meet CE marking requirements under the EU Pressure Equipment Directive (PED 2014/68/EU) for Category IV equipment (design pressure > 40 MPa). Documentation includes EU Declaration of Conformity, material certificates (EN 10204 3.1), and factory calibration reports traceable to PTB (Physikalisch-Technische Bundesanstalt) standards.

Software & Data Management

While the CPP700-H and CPP1000-H operate as standalone mechanical tools, they integrate seamlessly into digital calibration management ecosystems. When paired with compatible digital pressure modules (e.g., Beamex MC6, WIKA CPH6200), they feed real-time pressure data into calibration software platforms such as Beamex MX, MET/CAL, or UltraCal. All generated calibration records—including ramp rates, dwell times, hysteresis sweeps, and pass/fail status—can be exported in CSV or XML format. Audit trails comply with FDA 21 CFR Part 11 requirements when used within validated software environments supporting electronic signatures, user access controls, and immutable record retention.

Applications

• On-site verification and functional testing of safety-critical pressure relief valves (PRVs) and rupture discs in oil & gas, power generation, and chemical processing facilities.
• Factory acceptance testing (FAT) of high-pressure hydraulic actuators, accumulator pre-charge systems, and aerospace fluid control manifolds.
• Periodic calibration of pressure transmitters installed in ASME Section VIII Division 1 vessels and API RP 14C safety instrumented systems (SIS).
• Research-grade static pressure experiments requiring stepwise loading up to 100 MPa—used in materials science labs studying phase transitions in metallic alloys and ceramic composites.
• Training and certification exercises for Level 2 and Level 3 pressure calibration technicians under ILAC-G8 and EURAMET cg-18 guidelines.

FAQ

What is the maximum allowable working pressure for the CPP700-H and CPP1000-H?

The CPP700-H is rated for continuous operation up to 70 MPa; the CPP1000-H is rated for continuous operation up to 100 MPa. Both models include built-in mechanical pressure relief at 110% of rated pressure.
Can these pumps be used with water-based test media?

Yes—provided corrosion-inhibiting additives are used and the system is thoroughly flushed and dried after each use. For routine applications, ISO VG 22 mineral oil is recommended.
Is the Minimess® 1620 connector included with both models?

No—the Minimess® 1620 system is standard only on the CPP700-H. It is available as an optional accessory for the CPP1000-H (Order Code: MM-1620-KIT-1000).
Do the pumps include a factory calibration certificate?

Yes—each unit ships with a UKAS-accredited calibration certificate (ref. CT91.07) valid for 12 months from date of dispatch, covering pressure points at 25%, 50%, 75%, and 100% of full scale.
Are spare parts and service support available outside Germany?

York Instrument maintains authorized service centers in the US (Houston), UK (Milton Keynes), UAE (Dubai), and Singapore—with 48-hour turnaround for piston seal kits, check valve assemblies, and recalibration services.
