Description
AMETEK Crystal T-975-CPF – Pneumatic Pressure and Vacuum Calibration Hand Pump
The Crystal Engineering T-975-CPF Pneumatic Hand Pump by AMETEK Calibration is a compact, manually operated pneumatic calibration system designed for generating controlled pressure and vacuum during instrument testing, verification, and maintenance.
Part of the AMETEK T-900 Series, the T-975-CPF produces pressures from −27 inHg vacuum to +580 psi (−0.91 to +40 bar), making it suitable for testing mechanical and electronic pressure measurement instruments.
The pump features a protected pressure/vacuum shuttle valve, adjustable pumping stroke, precision vernier adjustment, and an integrated pressure vent valve.
Equipped with Crystal Pressure Fittings (CPF), the T-975-CPF provides secure, leak-resistant connections for reference pressure gauges and instruments under test.
Its lightweight construction makes it suitable for calibration laboratories, industrial workshops, oil and gas facilities, and field maintenance applications.
Key Features and Benefits
- Combined Pressure and Vacuum Generation: Produces pressure up to 580 psi (40 bar) and vacuum down to −27 inHg (−0.91 bar).
- Precision Fine Adjustment: Vernier valve provides fine-adjustment sensitivity down to 0.01 psi.
- Protected Shuttle Valve: Allows switching between pressure and vacuum modes after venting the system.
- Adjustable Pumping Stroke: Controls pressure generation per stroke and helps reduce the risk of overpressure.
- Dual Pressure Connections: Accommodates a calibrated reference instrument and the device under test.
- Integrated Vent Valve: Provides controlled pressure or vacuum release after testing.
- Crystal Pressure Fittings: CPF connections provide secure sealing without thread tape on the CPF connection itself.
- Included CPF Hose: Supplied with a 1-metre hose and compatible fittings.
- Compact and Portable: Suitable for laboratory and field calibration.
- Manual Operation: Requires no external electrical or compressed-air supply.
- Durable Construction: Anodized aluminum, brass, ABS, and stainless steel components.

Pressure Transmitter Verification
Test and verify industrial pressure transmitters at selected pressure points using a suitable reference instrument.
Vacuum Gauge Calibration
Generate controlled vacuum to verify gauges and transmitters designed for negative gauge pressure.
Pressure Switch Testing
Apply gradually increasing or decreasing pressure to check switching points and reset values.
Pneumatic Instrument Maintenance
Perform routine verification, troubleshooting, and commissioning of compatible pneumatic instruments.
Calibration Laboratories
Provide a portable pneumatic pressure source for reference-based instrument calibration.
Oil and Gas Industry
Support pressure instrument verification during site maintenance, commissioning, and inspection activities.
Included CPF Accessories
The T-975-CPF configuration includes:
- 5238: 3/8-inch BSP male to CPF male reference adapter.
- 5252: 5/16-24 SAE male to CPF female adapter.
- MPH-1: 1-metre CPF male hose.
- MPF-1/4FPT: CPF female to 1/4-inch NPT female adapter.
Additional CPF hose lengths, adapters, fitting kits, and carrying cases may be available separately.
Compatible Reference Instruments
The T-975-CPF can be paired with appropriately configured reference pressure instruments, including:
- AMETEK Crystal XP2i Digital Pressure Gauge
- AMETEK Crystal XP3i Digital Pressure Gauge
- AMETEK Crystal nVision Reference Recorder
- Other compatible reference pressure instruments
All connected instruments and accessories must be suitable for the intended pressure and vacuum ranges.
Why Choose the AMETEK Crystal T-975-CPF?
The AMETEK Crystal T-975-CPF combines controlled pressure generation, vacuum capability, precise adjustment, and a portable design in a single instrument.
Its protected shuttle valve and adjustable stroke make pressure generation convenient, while its CPF connection system simplifies the connection of reference gauges and instruments under test.
Unlike hydraulic comparators, the T-975-CPF uses air as its test medium, eliminating the need for hydraulic fluid during pneumatic instrument testing.
When combined with an appropriately calibrated reference instrument, it provides a practical solution for pressure and vacuum calibration in workshops, laboratories, and industrial field environments.
Important: The T-975-CPF is a pressure-generation device, not a pressure-measuring instrument. Always use a suitable calibrated reference gauge, and vent the system before changing the pressure/vacuum shuttle valve.
