Pressure calibration often demands flexibility. In some environments, engineers need fine low-pressure adjustment for sensitive instruments. In others, they need a robust high-pressure hydraulic solution that can be taken directly into the field. That is why having the right handheld pressure pump for the job matters.
Stork Solutions has expanded its pressure calibration offering with four new handheld pressure pumps designed to support a wide range of calibration requirements, from low-pressure pneumatic testing through to very high-pressure hydraulic calibration. These new products are:
- S4B Handheld Pressure Pump 4 Bar Range
- S40B Handheld Pressure Pump 40 Bar Range
- S700B Handheld Pressure Pump 700 Bar Range
- S1000B Handheld Pressure Pump 1000 Bar Range
Together, these portable pressure calibration pumps give technicians and engineers practical solutions for testing, adjusting and calibrating pressure gauges, switches and transmitters across a broad pressure spectrum.
Why handheld pressure pumps matter for calibration
A handheld pressure pump is one of the most useful tools in a calibration setup. It allows engineers to generate stable test pressure manually, fine-tune that pressure accurately and compare the device under test against a reference gauge or digital indicator.
For many businesses, handheld pumps are valuable because they offer:
- portability for field and on-site calibration
- independence from external power or pressure sources
- precise manual pressure generation
- easier commissioning, maintenance and service work
- suitability for workshops, laboratories and production environments
Whether you are verifying low-pressure transmitters or calibrating high-pressure process instrumentation, the right portable pump can make calibration faster, more practical and more reliable.
Overview of the new handheld pressure pump range
The new Stork Solutions range covers both pneumatic and hydraulic pressure calibration needs. Each model is designed for portability, control and dependable field use, while serving a distinct pressure range and application type.

- no need for nitrogen cylinders, compressed air networks or external power
The S40B is well suited to mobile calibration, field service work, workshops and laboratories where broad pressure coverage and portability are both priorities.
S700B Handheld Pressure Pump 700 Bar Range
For demanding hydraulic calibration tasks, the S700B Handheld Pressure Pump 700 Bar Range offers stable pressure generation up to 700 bar.
This model is built for high-pressure applications involving analogue and digital pressure gauges, pressure switches and transmitters. It combines a robust design with a large calibration volume of around 300 ml, helping users test larger systems while maintaining high pressure with relatively low manual effort.
Key highlights of the S700B include:
- hydraulic pressure generation up to 700 bar
- compact and robust industrial design
- large calibration volume for larger systems

The S700B is a strong fit for production, maintenance and quality assurance applications where repeatable high hydraulic pressure is needed in a mobile format.
S1000B Handheld Pressure Pump 1000 Bar Range
At the top end of the range, the S1000B Handheld Pressure Pump 1000 Bar Range is designed for the most demanding high-pressure calibration applications.
Capable of generating stable hydraulic pressure up to 1000 bar, the S1000B is aimed at users who need portable calibration equipment for very high-pressure gauges, switches and transmitters. It is particularly valuable in industrial environments, offshore maintenance and field service situations where reliability and repeatability are essential.
Key highlights of the S1000B include:
- hydraulic pressure generation up to 1000 bar
- robust design for challenging industrial use
- large calibration volume for larger test systems and components
- fine pressure setting and controlled pressure reduction

For organisations working at the upper end of the pressure range, the S1000B provides a practical solution that combines portability with very high-pressure performance.
Choosing the right handheld pressure pump
Selecting the right model depends largely on the pressure range and type of application you need to support.
If your work involves sensitive low-pressure calibration, the S4B Handheld Pressure Pump 4 Bar Range is likely the best fit. Its compact size and fine mbar control make it ideal for low-pressure testing and adjustment.
If you need a broader pneumatic range including vacuum through to 40 bar, the S40B Handheld Pressure Pump 40 Bar Range offers more versatility and can simplify calibration workflows by combining multiple functions into one unit.
For high-pressure hydraulic calibration up to 700 bar, the S700B Handheld Pressure Pump 700 Bar Range is a strong option for industrial use and larger calibration systems.
If your application demands very high-pressure testing up to 1000 bar, the S1000B Handheld Pressure Pump 1000 Bar Range is the most capable model in the range and is suited to the most demanding field and workshop environments.

Why this new range strengthens pressure calibration capability
By covering 4 bar, 40 bar, 700 bar and 1000 bar, this new handheld pressure pump range gives customers a clear path to match the right calibration tool to the right task. Instead of relying on a one-size-fits-all approach, engineers can choose a solution built for their actual working pressure and application demands.
