Turnkey test rig construction
Test rigs that measure what matters
Turnkey test rig systems for pump manufacturers and operators – designed for your test task, built for daily test operation.
A test rig is not a side project. It determines the quality of your acceptance tests, the validity of your development data and the confidence of your customers. L+K plans and supplies test rigs as a core product of its own: from the test task through hydraulic and mechanical design to commissioning at your site.

Test rigs for centrifugal pumps, positive displacement pumps – including multiphase operation – and injection pumps
We supply test rigs for a wide range of pump types. One example: for a pump manufacturer, we designed a test rig for positive displacement pumps that also covers multiphase operation – with supply, pressure maintenance and level control, precise data acquisition and safely separated media circuits.
5,000+ m³/hFlow rate – and beyond
100 barDesign at 100 °C
Pressure and temperature from a documented water/gas multiphase plant; we implement higher flow rates and other designs on a project-specific basis.
Pump types supplied
- Centrifugal pumps
- Positive displacement pumps – including multiphase operation
- Injection pumps and injectors
The views on this page are selected and anonymised – without customer names and without measurement data.
What we build for you
Pump test rigs for every pump type.
02
Positive displacement pumps & multiphase
Test rigs for positive displacement pumps, e.g. screw pumps – including multiphase operation.
03
Injection pumps
Test systems for injection pumps and injectors, documented for HFO/LFO up to 230 °C.
04
Modernisation of existing test fields
New instrumentation, automation and data acquisition for existing test rigs.
Special test rigs, too
Expansion joint test rig up to 300 bar
A special project: a test rig for the hydraulic testing of expansion joints up to 300 bar. It shows that we also solve unusual test tasks – when there is no off-the-shelf solution.
Confidentiality
Why we only show selected views.
Our test rigs are custom plants, and many projects are subject to non-disclosure agreements with our customers. That is why we only show selected, anonymised views on this website – no detailed photos, measurement data or customer names.
This discretion applies to your project as well. In a personal meeting we will be happy to present suitable references – within an agreed framework.
What you can expect from us
- Non-disclosure agreement before the first exchange, on request
- No publication of customer data or plant details
- References only with the approval of the respective customer
