What Is a Pneumatic Hand Calibration Pump?
A pneumatic hand calibration pump is a manually operated pressure-generation device used to create controlled air pressure or vacuum for checking pressure-measuring instruments.
During calibration or functional testing, the pump is connected to a reference gauge or indicator and the device under test. The operator manually generates pressure or vacuum and compares the indication of the test instrument with the reference instrument.
The CARE-PHP40 can be used for checking compatible instruments such as:
-
Pneumatic digital indicators
-
Manometers
-
Pressure transducers
-
Pressure transmitters
-
Pneumatic loops
-
Pressure gauges
-
Compatible pneumatic instruments
Because it is hand operated, the pump does not require an external compressed-air source or electrical power supply for pressure generation.
Its compact size and approximate weight of 750 grams make it suitable for workshop, laboratory and field-maintenance activities.
The pump includes separate ports for the reference gauge or indicator and the device under test. This allows both instruments to experience the same generated pressure during comparison.
CARE-PHP40 Product Overview
The CARE-PHP40 combines pressure and vacuum generation in one portable calibration device.
A pressure/vacuum changeover option allows the operator to select the required operating direction. This can reduce the need to carry separate pumps for positive-pressure and vacuum calibration work.
The pump is designed with a fine-adjustment vernier, enabling controlled changes after the approximate pressure has been generated manually.
The vernier mechanism provides pressure sensitivity or resolution down to the millibar level, supporting more precise adjustment of the test point.
The instrument is also designed for a very low leakage rate. Low leakage is important during calibration because pressure should remain sufficiently stable while the readings of the reference instrument and device under test are compared.
The standard hose arrangement includes a one-metre flexible nylon hose with a swivel adaptor.
The swivel adaptor allows the connecting hose to be attached to the device under test while reducing unnecessary twisting of the hose or instrument connection.

How the Calibration Pump Works
The CARE-PHP40 generates pneumatic pressure through manual operation.
The reference gauge or indicator is connected to the designated gauge port, while the instrument under test is connected through the test port and flexible nylon hose.
After confirming that all connections are secure, the operator selects either pressure or vacuum mode through the changeover arrangement.
The hand-operated mechanism is then used to generate the approximate test pressure.
Once the required pressure is approached, the fine-adjustment vernier is used to increase or decrease the pressure in a controlled manner.
The readings of the reference instrument and device under test can then be compared at the selected calibration points.
A typical checking sequence may include:
-
Connecting the reference instrument.
-
Connecting the device under test.
-
Confirming that the fittings are secure.
-
Selecting pressure or vacuum mode.
-
Generating the approximate test pressure.
-
Using the vernier for fine adjustment.
-
Allowing the pressure to stabilize.
-
Comparing both instrument readings.
-
Recording the observed values.
-
Safely releasing the pressure after the test.
The exact calibration procedure should follow the approved method of the laboratory, plant or quality-management system.
Combined Pressure and Vacuum Operation
The CARE-PHP40 provides both positive-pressure and vacuum generation within one unit.
This feature is useful where technicians must check instruments operating in different pressure regions.
Positive-Pressure Testing
In pressure mode, the pump creates a pneumatic pressure above atmospheric pressure.
This mode can be used for compatible pressure gauges, transmitters, transducers and digital pressure indicators within the pump’s specified generation capability.
Vacuum Testing
In vacuum mode, the pump creates pressure below atmospheric pressure.
The stated vacuum-generation capability is up to 0.95 bar.
This mode can be used for checking compatible vacuum instruments, compound-pressure instruments and devices that operate below atmospheric pressure.
Before changing between pressure and vacuum modes, the operator should ensure that the system pressure has been safely released according to the operating procedure.
Fine-Adjustment Vernier
The fine-adjustment vernier is one of the main functional features of the CARE-PHP40.
Manual pumping is used to reach the approximate pressure level, while the vernier enables finer control near the required test point.
The supplied specification states that the vernier can achieve pressure resolution or sensitivity down to the millibar level.
This feature is useful when the calibration procedure requires the pressure to be set close to a defined point.
Fine adjustment can help the technician:
-
Approach the required pressure gradually.
-
Correct minor pressure deviations.
-
Stabilize the selected test point.
-
Avoid excessive manual pumping.
-
Compare readings at specific pressure values.
-
Carry out ascending and descending pressure checks.
The achievable stability and adjustment performance also depend on the condition of the connecting hose, fittings, seals, reference instrument and device under test.
Low-Leakage Design
The pump is specified with a very low leakage rate.
Leakage control is important in pneumatic calibration because pressure loss can cause the reference value to drift during observation.
A stable test setup allows the operator sufficient time to:
-
Read the reference instrument.
-
Read the device under test.
-
Record the values.
-
Check repeatability.
-
Observe pressure drift.
-
Carry out adjustment where permitted.
Even with a low-leakage pump, the complete calibration arrangement should be inspected for leaks.
Potential leak points include:
-
Threaded connections
-
Hose fittings
-
Swivel adaptor
-
Reference gauge connection
-
Device-under-test connection
-
Sealing washers
-
Damaged tubing
-
Loose adaptors
All fittings should be compatible with the stated connection sizes and pressure requirement.
Flexible Nylon Hose and Swivel Adaptor
The CARE-PHP40 is supplied with a one-metre flexible nylon hose.
The hose provides a practical connection between the pump and the device under test.
Its flexible construction can assist technicians when the instrument is mounted on equipment, installed in a panel or positioned away from the pump.
A swivel adaptor is provided for connection to the device under test.
The swivel arrangement can simplify connection by allowing the adaptor to rotate without twisting the entire hose.
Before use, the hose should be checked for:
-
Cuts
-
Abrasion
-
Kinks
-
Hardening
-
Loose fittings
-
Damaged threads
-
Leakage
-
Contamination
The hose should only be used within the approved pressure and service conditions.
Connection Ports
The pump is provided with two designated connection ports.
Test Connection Port
The test connection port is:
1/4-inch female BSP
This port is used for connecting the device under test through the supplied hose or a suitable adaptor arrangement.
Gauge or Indicator Connection Port
The reference instrument connection is:
3/8-inch female BSP
This port is intended for the reference gauge or indicator used during the checking or calibration process.
The correct male BSP fitting or approved adaptor should be used with each female connection.
Thread type and size should be verified before assembly. Incompatible threads should not be forced together.
Suitable sealing methods should be used according to the approved calibration procedure and fitting design.
Compact and Lightweight Construction
The CARE-PHP40 has approximate dimensions of:
230 × 140 × 65 mm
The dimensions are stated as height × width × depth.
Its approximate weight is:
750 grams
