How does the Hydraulic Test Pac generate pressure without an electrical power supply?

The unit uses an air-driven hydraulic pump (Model MS-110). A supply of compressed shop air drives the pump, and the air-drive pressure regulator setting determines the final hydraulic output pressure. The pump automatically stalls once the set pressure is reached and consumes no further energy while stalled, so it can hold pressure indefinitely without any electrical input.

Hydraulic Test Pac With Chart Recorder, engineered to stall at zero standby power.

A portable, self-contained hydro-pressure test unit powered entirely by compressed shop air. Setting the air-drive pressure regulator determines the final hydraulic output pressure — the pump stalls automatically once the target pressure is reached and holds it indefinitely with zero further energy draw, while the integral Rototherm chart recorder plots a continuous trace of the test.

The Hydraulic Test Pac With Chart Recorder is a portable, lightweight hydro-testing unit built for shop-floor and onsite pressure testing, producing a chart record to monitor the process as it happens.

The unit is entirely self-contained and powered by compressed air — it requires nothing more than a supply of compressed shop air to drive the liquid pump. A simple adjustment of the air-drive pressure regulator setting determines the final hydraulic output pressure.

The pump stalls automatically once the desired hydraulic pressure is reached, consumes no further energy, and can hold that pressure indefinitely in the stalled condition.

That auto-stall behaviour makes the Test Pac ideal for long-duration proof-pressure holds without an operator standing by, while the built-in Rototherm circular chart recorder continuously traces the pressure over time — giving an auditable record for quality assurance, customer witness testing, and defence/aerospace documentation requirements.

Engineering narrative for test-floor engineers, quality teams, and procurement evaluating the Test Pac before purchase.

1. Introduction

The Hydraulic Test Pac With Chart Recorder is portable, lightweight hydro-testing equipment designed for shop-floor and onsite pressure testing, generating a chart record to monitor the process. The unit is self-contained and powered by compressed air — it requires only a supply of compressed shop air to power the internal liquid pump.

A simple adjustment of the air-drive pressure regulator setting determines the final hydraulic output pressure, and the pump automatically stalls once the desired hydraulic pressure is attained. When stalled, the pump consumes no further energy and can remain in the stall condition indefinitely — holding test pressure with no operator intervention and no ongoing power draw.

2. How it works

Air supply in: compressed shop air enters through the 1/4" BSPF air filter (150 psi W.P.) and air-inlet pressure gauge.
Regulated drive: the air-drive pressure regulator setting is adjusted to set the desired final hydraulic output pressure.
Pump conversion: the MS-110 air-driven pump converts the regulated air drive into hydraulic pressure at the outlet.
Auto-stall hold: once the set hydraulic pressure is reached, the pump stalls automatically and holds pressure with zero further energy consumption.
Chart record: the Rototherm circular chart recorder plots the pressure continuously throughout the hold, producing a documented test trace.

3. Applications

Shop-floor testing: proof-pressure testing of hydraulic components and assemblies before dispatch.
Onsite/field testing: mains-independent operation makes it suited to customer-site and field pressure tests.
Hose and fitting verification: pressure-tests hydraulic hoses and fittings with a documented chart trace.
Defence, aerospace, railway and industrial sectors: qualification and acceptance testing of hydraulic sub-systems.
