Micropac pumps for Pressure Test Rigs from simple solutions to complex requirements.

Can you supply a Pressure Test Rig?

Yes, we can supply a Pressure Test Rig ranging from a basic pressure test rig for a simple hydrotesting requirement through to a versatile catalogue programmable hydraulic pressure test rig. Beyond that, we don’t get involved in complicated rigs for multiple tests. You need to talk to a custom Pressure Test Rig supplier at that point. We can also supply component pumps for your own rig builder to integrate into a unit.

The term “Pressure Test Rig” does mean different things to different people. It could mean anything from a basic hydrostatic pressure test reservoir with its pump head as a carry-around right through to a free-standing aerospace test rig at substantial cost and sophistication. Our white paper discusses Pressure Test Rigs in more depth.

What is the most basic Pressure Test Rig that you can supply?

Our most basic Pressure Test Rig is our MW series hydrostatic test hand pump mounted on a reservoir and forming a neat carry-around MP series test unit. Or opt for a fixed reservoir if you wish to bolt the Pressure Test Rig to a frame or bench. The fixed reservoir is specified by adding the part to the MW pump ordering code. Add a hose and hydraulic adaptor to start your testing. Tell us what you require.

Can you supply a mobile hydraulic service cart to form my Pressure Test Rig?

For a 20 litre/5.3USG reservoir and larger, we recommend the neat 2 wheel cart unit, the MP-unit with trolley reservoir. Select the 20L/5.3USG or 50L/13.2USG reservoir then the pump head to suit your requirement. Single or dual speed hydrotest pump. Various displacements and pressures between 100cc/stroke and 1000 bar. Various seal compounds and materials all on short lead time and good value Micropac catalogue items.

What can I add to a basic cart Pressure Test Rig to aid productivity?

Look at our TX cart which adds an integral organiser to store the designated fittings for your test job and a sleeve for storage of documentation. That’s what customers asked us for to make life easier in the shop or on site. Taking longer to find the fittings than doing the test is not very satisfactory.

How can I adapt my basic Micropac Pressure Test Rig for a job?

We would add a hose and sort the exact fittings for your requirement. Consider using snap couplings with the coupler on the end of your hose and the probes as the fittings for your test piece or system. That provides a step up in productivity. Store your fittings in the tray on the TX service cart.

How can I speed up prefilling and testing on my Micropac Pressure Test Rig?

Consider adding a compact air driven pump to reduce pumping by hand.

Look at our DUO pump which in one compact cart integrates our Micropac hand pump and a very neat air driven pump. The air pump operating pressure is set on the integrated regulator. Use 100% air driven pump for deskilled and fast operation. The DUO offers an invaluable hand pump for final pressure top up or when there is no shop air supply available. This is a very neat pressure test rig unit to which you add a hose and fittings for hydrostatic pressure test tasks.

How do I add safety protection to my Pressure Test Rig?

Safety is an over-riding need. If you are pressure testing a work piece, do risk assess what happens if it leaks or bursts. Make a cover for the test piece or consider our MTE test enclosure that provides some protection from debris or fluid. There is also an enhanced ballistic protection chamber option in the range.

Are a pressure test rig and a hydrotest pump the same?

This is a question that regularly crops up. This is our take in our article after manufacturing this equipment for over 40 years.

A pressure test rig covers are wide range of products. We have a thoughtful white paper that focusses on what you are trying to achieve. A basic carry-around hydrotest pump might be perfect. At the other end of the scale, you might require a sophisticated pressure test rig that is floor standing and operated by a touch screen costing a lot of money. Read our white paper to understand our take in moving from very basic to sophisticated.

I require an automated programmable Pressure Test Rig which cycles the pressure up and down but at a reasonable price.

A Pressure Test Rig that will pressure test in pre-programmed cycles is very much higher end pressure test rig territory. Our Micropac PTR-A automated Pressure Test Rig is a solution for simple pressurise/depressurise cycles repeated again and again. For example, if you wish to pressurise a workpiece to 300 bar for 40 seconds, hold for 120 seconds, release the pressure for 10 seconds to ensure it is at zero, dwell for 10 seconds before starting again and repeat this 5K times, we can supply you our PTR-A benchtop automated pressure test rig as a catalogue unit.  You programme it using the intuitive touch screen and there are safeguards built in like stopping the cycle if something is leaking and has not reached pressure after so many seconds. This is a cost effective solution and suitable for multiple fluids including water. Users have found them a great solution for high cycle fatigue or creep pressure testing for components including automotive fuel tanks, consumer items like radiators and more specialist parts such as composite pressure vessels for aerospace.

If you require a Pressure Test Rig that can offer a greater control of the cycle or multiple cycles following each other, you are into customer test rig territory and need to ask a specialist.

Which Micropac hand pumps are used by rig builders in Pressure Test Rigs?

Some of our hand pumps are used for hydraulic clamping of the test piece or fixture. Most are piped into the circuit of a more sophisticated Pressure Test Rig to generate the pressure needed for hydrostatic testing. Designers will specify precisely what they need in terms of the release/hold valve, relief valve and inlet or outlet connections. You order precisely what you require. For example, if you need a Micropac MD series stainless steel two speed pump with peroxide cured EPDM seals for “skydrol” and with no release or relief valve but 3/8NPT female ports, then the ordering code describes what you need. Our units work from 0.5 bar through to 1000 bar on multiple fluids.
