Magnum Pro PP-4 is a powerful high-pressure pneumatic pump designed for professional pressure calibration, testing and maintenance applications. With a pressure range from 0 to 3,000 psi / approximately 207 bar, the PP-4 generates high pneumatic pressures without requiring hydraulic oil, water or heavy nitrogen cylinders.
This makes the Magnum Pro PP-4 particularly suitable for applications where contamination of the device under test with liquids must be avoided. Pressure transmitters, gauges, sensors and other sensitive process instruments can be pressurized using clean compatible gas rather than hydraulic fluid.
The PP-4 can be operated either by hand or by foot. Two folding support legs stabilize the pump during operation, while retractable foot pedals allow the operator to generate pressure from a comfortable standing position. For laboratory use, the pump can also be positioned alongside a calibration bench.
A precision vernier adjustment provides fine control of the generated pressure. Once the approximate calibration pressure has been generated, the vernier can be used to approach the desired pressure point accurately and stabilize the pressure for measurement.
Two pressure ports provide convenient connection of a reference pressure instrument and the pressure system or device under test. The current manufacturer specification identifies two 1/4″ NPT/BSP pressure connections.
At only approximately 5 lb, the Magnum Pro PP-4 provides an unusually portable solution for pneumatic pressure generation up to 3,000 psi. It eliminates the need to transport heavy nitrogen bottles and regulators to field calibration locations.
At europascal, the Magnum Pro PP-4 can be combined with suitable precision digital pressure references, high-pressure hoses and adapters to create a complete pneumatic comparison calibration system.

Pneumatic Pressure Generation up to 3,000 psi
The Magnum Pro PP-4 has a current specified operating range of:
0 to 3,000 psi
which corresponds to approximately:
0 to 207 bar.
This is an exceptionally high pressure range for a manually operated pneumatic pressure source.
Many portable pneumatic hand pumps are designed for substantially lower pressures. The PP-4 extends pneumatic pressure generation into a range that would otherwise often require bottled nitrogen or hydraulic pressure generation.
No Hydraulic Fluid Required
One of the main advantages of the Magnum Pro PP-4 is that high pressure is generated pneumatically.
No hydraulic liquid is required.
This is particularly important when testing sensitive pressure instruments that should not be contaminated with:
- Hydraulic oil
- Water
- Other liquid pressure media
The PP-4 therefore provides an attractive alternative to hydraulic hand pumps for compatible devices within its pressure range.
Protect Sensitive Process Instruments
Liquid contamination can be problematic when calibrating pressure transmitters, sensors and other instruments designed for clean pneumatic applications.
Residues of oil or water can enter the internal pressure system of the device under test when a hydraulic pressure generator is used.
The Magnum Pro PP-4 avoids this problem by generating the required calibration pressure pneumatically.
This makes it particularly useful for sensitive process instrumentation.
No Heavy Nitrogen Bottles
High pneumatic pressures are frequently generated using:
compressed nitrogen cylinders + pressure regulator.
Although effective, this method requires transporting and handling a heavy compressed-gas cylinder.
The Magnum Pro PP-4 provides an alternative.
Pressure is generated mechanically by the operator, eliminating the need for a nitrogen bottle in many calibration applications.
This significantly improves portability for field service.
Hand or Foot Operation
The Magnum Pro PP-4 can be operated:
by hand
or:
by foot.
This flexibility allows the operator to select the most convenient method for the application.
For field use, hand operation provides maximum flexibility.
For repeated pressure generation, foot operation can reduce physical effort.
Retractable Foot Pedals
The PP-4 incorporates:
retractable foot pedals.
The pedals can be deployed when the pump is used for foot-operated pressure generation.
For transportation, the mechanism folds into a much more compact configuration.
This contributes to the portable design of the pump.
Folding Support Legs
Two support legs can be folded out to stabilize the Magnum Pro PP-4 during operation.
The support structure provides a stable base when pressure is generated by hand or foot.
When transportation is required, the supports can be folded back into the pump.
The manufacturer describes the folded system as compact enough for a mailing-tube-sized carrying arrangement.
Fine Vernier Adjustment
Generating the approximate pressure is only the first part of a calibration procedure.
The operator must then adjust the pressure precisely to the required measurement point.
The PP-4 therefore incorporates a:
fine vernier pressure control.
The vernier allows small pressure changes to be made after the main pressure has been generated.
This is particularly useful when approaching defined calibration points.
Pressure Stabilization
The vernier can also be sealed after the desired pressure has been reached.
This helps stabilize the pressure and minimize unwanted pressure changes during measurement.
Stable pressure is essential when comparing a reference instrument with the device under test.
Two Pressure Ports
The Magnum Pro PP-4 provides:
two pressure ports.
The current manufacturer specification identifies these as:
2 × 1/4″ NPT/BSP.
One connection can be used for a precision reference pressure gauge.
The second connection can be connected to a high-pressure hose leading to the device under test.
This makes the PP-4 particularly suitable for comparison calibration.
Comparison Calibration
A typical calibration arrangement consists of:
Magnum Pro PP-4 + Reference Pressure Gauge + Device Under Test
The PP-4 generates the pneumatic pressure.
The reference instrument measures the actual applied pressure.
The device under test is exposed to the same pressure.
The indication of the DUT can then be compared with the reference value.
Pressure Generator – Not a Pressure Reference
The Magnum Pro PP-4 is a pressure generator.
It does not independently determine the actual reference pressure.
For calibration applications, a suitable reference pressure instrument is therefore required.
The basic functions are:
PP-4 = Pressure Generation
Reference Gauge = Pressure Measurement
DUT = Device Under Test
The accuracy and measurement uncertainty of the calibration depend on the selected reference and the complete calibration setup.
Pressure Gauge Calibration
The Magnum Pro PP-4 can be used for pneumatic calibration of pressure gauges.
The reference pressure gauge and DUT are connected to the same pressure system.
The operator generates the required calibration points with the PP-4.
A typical sequence may include:
0% → 20% → 40% → 60% → 80% → 100%
of the DUT range.
The pressure can subsequently be reduced through the same measurement points.
The deviation of the DUT from the reference can then be determined.
Digital Pressure Gauge Calibration
The Magnum Pro PP-4 is also suitable for calibration and testing of digital pressure gauges.
A high-accuracy digital reference pressure gauge can be connected to one pressure port.
The digital pressure gauge under test is connected to the second pressure line.
The PP-4 provides the pneumatic pressure required for the comparison.
Pressure Transmitter Calibration
One of the particularly useful applications of the PP-4 is pressure transmitter calibration.
A typical setup consists of:
PP-4 + Pressure Reference + Electrical Calibrator + Pressure Transmitter
The PP-4 generates the pressure.
The pressure reference measures the actual input pressure.
The electrical calibrator measures the transmitter output.
For a conventional industrial pressure transmitter, this is commonly:
4 to 20 mA.
The complete pressure-to-current characteristic can therefore be tested.
Pressure Sensor Testing
Pressure sensors and transducers can also be tested with the Magnum Pro PP-4.
The pneumatic pressure generated by the PP-4 is applied simultaneously to the DUT and reference pressure instrument.
The sensor’s electrical output can then be recorded at different pressure points.
Pressure Switch Testing
The PP-4 can provide the pneumatic pressure required for pressure switch testing.
Pressure is increased until the switch changes state.
The corresponding pressure is measured by the reference instrument.
Pressure can subsequently be reduced until the switch resets.
This allows determination of:
- Switching pressure
- Reset pressure
- Switching hysteresis
Clean Pneumatic Calibration
A major advantage of the Magnum Pro PP-4 is the ability to perform high-pressure testing without introducing hydraulic fluid into the pressure system.
This is particularly relevant for:
- Gas pressure transmitters
- Pneumatic sensors
- Clean process systems
- Sensitive pressure instrumentation
- Instruments that must remain oil-free
The suitability of the test gas and pressure connections must always be verified for the particular DUT.
Cold-Temperature Applications
The manufacturer also highlights another advantage of avoiding water as a pressure medium.
Because the PP-4 operates pneumatically, there is no water inside the pressure generation system that can freeze at low temperatures.
This can be advantageous for outdoor field applications.
Portable Field Calibration
The Magnum Pro PP-4 is designed for both laboratory and field use.
At approximately:
5 lb
the pressure generator is considerably easier to transport than a high-pressure gas cylinder and regulator system.
The folding support legs and retractable pedals further improve portability.
Laboratory Use
The PP-4 can also be used alongside a calibration bench.
In this configuration, a precision reference pressure gauge can remain connected to the pump while different devices under test are connected through the high-pressure hose.
This creates a practical manual pneumatic calibration station.
PP-4 and Winchester Model 1
Magnum Pro offers a system combining the PP-4 with the:
Winchester Model 1 Auto Ranging Digital Gauge.
The Model 1 provides automatic pressure measurement over a broad range extending to 3,000 psi.
This matches the current maximum pressure specification of the PP-4 particularly well.
The combination provides both:
Pressure generation + Reference pressure measurement.
PP-4WIN
The corresponding system configuration is designated:
PP-4WIN.
The documented configuration combines the PP-4 equipment with a Winchester Engineering Model 1 Auto Ranging Digital Gauge.
This creates a portable high-pressure pneumatic calibration system.
PP-4WIN2
Another documented configuration is:
PP-4WIN2.
This version combines the PP-4 system with the Winchester Engineering Model 2 Wide Range Digital Gauge.
The appropriate configuration should be selected according to the required pressure range and measurement performance.
High-Pressure Hoses
Magnum Pro offers high-pressure calibration hoses for pneumatic and hydraulic applications.
The manufacturer’s high-pressure hose documentation specifies configurations suitable for pressures up to:
10,000 psi working pressure.
Different connection configurations are available.
The actual hose and fittings used with the PP-4 must always be rated for at least the maximum applied pressure.
Compact Transportation
The PP-4 is designed to fold into a compact format for transportation.
This is particularly useful for service technicians who would otherwise need to transport:
- Nitrogen bottle
- Pressure regulator
- Hoses
- Pressure reference
- Adapters
The PP-4 can substantially reduce the size and weight of the pressure-generation equipment required for field work.
Two-Year Warranty
The Magnum Pro PP-4 is supplied with the manufacturer’s:
2-year “Quibble-Free” warranty.
The current manufacturer information states that this warranty also covers dropping the unit.
This reflects the pump’s intended use as rugged field equipment.
