europascal EP-P700 is a powerful and compact hydraulic pressure test pump designed for professional comparison calibration of pressure gauges, transmitters, sensors and other pressure measuring instruments. With manual pressure generation from 0 to 700 bar / approximately 10,000 psi, the EP-P700 provides a portable solution for high-pressure calibration in laboratories, workshops and field applications.
The europascal EP-P700 can be operated with hydraulic oil or distilled water, allowing the pressure medium to be selected according to the device under test and the requirements of the calibration application.
Despite its high pressure capability, the EP-P700 weighs only approximately 1.7 kg. Its compact design makes it particularly suitable for mobile calibration and service work where a conventional bench-mounted pressure comparator would be too large or heavy.
The EP-P700 operates according to the comparison calibration principle. A suitable reference pressure gauge is connected to the reference port, while the device under test is connected through the pressure hose. The hand pump generates the common pressure for both instruments, allowing the indication of the DUT to be compared directly with the reference.
A large-volume fine adjustment valve with an ultra-fine thread pitch allows precise pressure adjustment, including adjustment in the low mbar range. This combination of high maximum pressure and sensitive fine adjustment makes the EP-P700 a versatile manual pressure source for professional pressure calibration.
At europascal, the EP-P700 can be combined with suitable digital reference pressure gauges and calibration equipment to create complete hydraulic pressure calibration systems. For professional calibration and metrological traceability, visit the europascal Calibration Service.

Hydraulic Pressure Generation up to 700 bar
The europascal EP-P700 provides a pressure range of:
0 to 700 bar
or approximately:
0 to 10,000 psi.
This makes the pump suitable for a wide variety of medium- and high-pressure calibration applications.
Typical devices under test include:
- Analog pressure gauges
- Digital pressure gauges
- Pressure transmitters
- Pressure sensors
- Pressure transducers
- Pressure switches
The high maximum pressure allows the same pump to cover a large portion of common industrial hydraulic pressure ranges.
Manual Pressure Generation
The europascal EP-P700 is operated manually.
No electrical power supply is required for basic pressure generation.
This makes the pump particularly suitable for:
- Field service
- Mobile calibration
- Maintenance departments
- Calibration laboratories
- Workshops
- Production environments
Pressure can be generated wherever the calibration needs to be performed without requiring an electric pressure controller.
Single-Stage Hydraulic System
The europascal EP-P700 uses a:
single-stage hydraulic system.
The manual pumping mechanism allows pressure to be generated up to 700 bar while maintaining a compact overall design.
The straightforward hydraulic design makes the EP-P700 a practical pressure source for routine comparison calibration.
Hydraulic Oil or Distilled Water
The EP-P700 can be operated using:
hydraulic oil
or:
distilled water.
This flexibility is particularly useful when different devices under test have different media requirements.
Hydraulic oil is commonly used for conventional hydraulic pressure instruments.
Distilled water can be advantageous when oil contamination of the device under test must be avoided.
The pressure medium should always be selected according to the compatibility requirements of the DUT and the applicable calibration procedure.
Comparison Calibration
The europascal EP-P700 is designed for:
comparison pressure calibration.
The basic calibration setup consists of:
EP-P700 + Reference Pressure Gauge + Device Under Test
The EP-P700 generates pressure.
The reference pressure gauge measures the generated pressure.
The device under test is exposed to the same pressure.
Its indication can then be compared directly with the reference instrument.
Pressure Generator – Not a Pressure Reference
It is important to distinguish the function of the EP-P700 from that of a digital pressure gauge or pressure calibrator.
The:
europascal EP-P700 generates and adjusts pressure.
The:
reference pressure gauge measures the pressure.
The EP-P700 itself therefore does not determine the accuracy of the reference pressure.
The measurement uncertainty of the complete calibration system depends on the selected reference instrument, calibration procedure, environmental conditions and other relevant uncertainty contributions.
Reference Pressure Gauge Connection
The europascal EP-P700 provides a dedicated connection for the reference pressure instrument.
The reference connection is:
G1/4″.
A suitable precision digital pressure gauge can therefore be installed as the reference.
The reference instrument should be selected according to the required:
- Pressure range
- Accuracy
- Resolution
- Measurement uncertainty
- Calibration traceability
Device Under Test Connection
The device under test is connected through a separate:
G1/4″ connection with quick coupling.
The EP-P700 is supplied with a pressure hose approximately:
1 metre
in length.
This flexible connection makes it easier to calibrate pressure gauges and other devices that cannot be mounted directly on the pump.
Convenient Hose Connection
The pressure hose provides additional flexibility during calibration.
Large pressure gauges, transmitters or sensors can be positioned next to the pump instead of being mounted directly onto the pressure generator.
This is particularly useful for:
- Large analog pressure gauges
- Heavy transmitters
- Awkwardly positioned pressure connections
- Field calibration
- Workshop applications
The hose also reduces the mechanical load that a large DUT could otherwise apply directly to the pump connection.
Fine Pressure Adjustment
Precise comparison calibration requires more than simply generating high pressure.
The required calibration points must also be approached accurately.
For this purpose, the europascal EP-P700 incorporates a fine pressure adjustment mechanism.
A large-volume regulating valve with an ultra-fine thread pitch allows small changes in pressure to be made after the main pressure has been generated.
Adjustment in the Low mbar Range
A notable feature of the EP-P700 is its ability to make fine pressure adjustments even in the:
low mbar range.
This provides a very broad adjustment capability for a manual hydraulic pump with a maximum pressure of 700 bar.
The fine adjustment mechanism helps the operator approach defined calibration points accurately without excessive pumping and venting.
Pressure Gauge Calibration
One of the primary applications for the europascal EP-P700 is pressure gauge calibration.
The reference gauge is connected to the reference port.
The pressure gauge under test is connected to the pressure hose.
The operator then generates a series of calibration pressures.
A typical sequence can include:
0% → 20% → 40% → 60% → 80% → 100%
of the calibration range.
The pressure can then be reduced through the same measurement points.
This allows deviations between the reference and DUT to be determined across the pressure range.
Depending on the calibration procedure, measurements in increasing and decreasing pressure can also be used to evaluate hysteresis.
Digital Pressure Gauge Calibration
The EP-P700 is equally suitable for calibrating digital pressure gauges.
A higher-accuracy digital pressure reference is connected to the reference port while the digital gauge under test is connected through the pressure hose.
The generated pressure is then compared at each calibration point.
This creates a compact manual calibration system without requiring an automated pressure controller.
Pressure Transmitter Calibration
The europascal EP-P700 can be used as a hydraulic pressure source for pressure transmitter calibration.
A typical setup consists of:
EP-P700 + Pressure Reference + Electrical Calibrator + Pressure Transmitter
The EP-P700 generates the required pressure.
The pressure reference determines the actual applied pressure.
The electrical calibrator measures the transmitter output.
For conventional industrial transmitters, this is frequently a:
4 to 20 mA
signal.
This allows the complete pressure-to-electrical conversion characteristic of the transmitter to be tested.
Pressure Sensor and Transducer Testing
Pressure sensors and transducers can be tested using the same principle.
The EP-P700 provides the hydraulic pressure input while a suitable reference instrument measures the actual pressure.
The output of the sensor can then be recorded at defined calibration points.
Depending on the DUT, the output may be:
- Current
- Voltage
- Frequency
- Digital data
The EP-P700 remains the hydraulic pressure source within the measurement system.
Pressure Switch Testing
The europascal EP-P700 can also be used for testing hydraulic pressure switches.
Pressure is gradually increased until the switch changes state.
The switching pressure is determined using the connected reference pressure gauge.
The pressure can then be reduced until the switch resets.
This enables determination of:
- Switching point
- Reset point
- Switching hysteresis
The fine adjustment mechanism helps the operator approach the switching point accurately.
Integrated Fluid Reservoir
The EP-P700 incorporates its hydraulic fluid reservoir directly into the pump.
An external oil or water reservoir is therefore not required for normal operation.
This contributes to the compact and portable construction of the system.
The operator can transport the pressure source as one integrated unit.
Stainless Steel Construction
The europascal EP-P700 is manufactured with:
stainless steel
as a primary construction material.
This supports robust operation in laboratory, workshop and field environments.
The construction is designed for repeated use as a professional calibration pressure source.
Compact Dimensions
The EP-P700 has approximate dimensions of:
255 × 225 × 85 mm.
This compact footprint is notable considering the maximum pressure of 700 bar.
The pump can therefore be used on calibration benches with limited available space and can also be transported conveniently for field applications.
Only Approximately 1.7 kg
One of the key advantages of the europascal EP-P700 is its low weight.
The pump itself weighs approximately:
1.7 kg.
This makes it significantly easier to transport than many conventional high-pressure bench comparators.
The low weight is particularly valuable for service technicians who regularly perform calibrations at customer or production locations.
Complete Calibration Case
The EP-P700 can be supplied as a complete portable set in a protective transport case.
The case contains the pump together with the required accessories.
This keeps the pressure pump, adapters and seals organized and protected during transportation.
Standard Adapter Set
The complete EP-P700 set includes adapters for commonly used industrial pressure connections.
The documented standard adapter set includes:
- G1/8″
- G1/4″
- G3/8″
- G1/2″
- 1/8″ NPT
- 1/4″ NPT
- 1/2″ NPT
- M12 × 1.5
- M20 × 1.5
- G1/8″ A
- G1/4″ A
This broad selection allows many common pressure gauges and transmitters to be connected without purchasing a separate adapter for every application.
Stainless Steel Adapters
The standard adapter set is manufactured from:
stainless steel.
This provides a robust connection solution suitable for professional pressure calibration.
Correct seals and pressure ratings must always be observed when configuring the pressure system.
Seal Kit
The complete calibration set also includes a:
seal kit.
The documented set contains:
PA seals and O-rings.
Having the appropriate replacement seals directly in the transport case is particularly useful during field calibration.
Complete Case Dimensions
The complete transport case has approximate dimensions of:
450 × 370 × 125 mm.
This provides sufficient space for:
- EP-P700 pump
- Pressure hose
- Adapter set
- Seal kit
- Accessories
The complete case weighs approximately:
4.8 kg.
The complete system therefore remains highly portable.
Field Calibration
The compact construction makes the europascal EP-P700 particularly suitable for field calibration.
A technician can transport the pump, reference gauge and required adapters directly to the device under test.
This can reduce the need to remove permanently installed pressure instruments from a machine or process system.
For suitable applications, calibration can therefore be performed directly at the installation location.
Laboratory Calibration
The EP-P700 is equally suitable as a manual pressure source in a calibration laboratory.
Combined with an appropriate precision reference, it provides a straightforward comparison system for routine hydraulic pressure calibration up to 700 bar.
The manual operating principle can be particularly economical when an automated pressure controller is not required.
No Electrical Power Required
The europascal EP-P700 generates pressure mechanically.
No electrical power supply is required for pressure generation.
This makes the pump independent of:
- Mains electricity
- Batteries
- Compressors
- External hydraulic power units
Only the connected electronic reference instrument may require electrical power.
This independence is a major advantage for mobile service applications.
