Asada Electric Pressure Test Pump EP440

Asada Corporation is a Japanese manufacturer of professional pipe and bolt threading equipment, threading dies, pressure test pumps, and pipe working machinery for plumbing, gas fitting, mechanical services, and industrial maintenance applications. Their machines and dies are engineered to produce clean, accurate threads to BSP, NPT, and metric standards, and their pressure test pumps are widely used for testing pipework integrity after installation.

Asada pressure test pumps are used to hydrostatically test pipework systems after installation, verifying that joints and fittings are leak-free before the system is commissioned. Available in manual and electric configurations, they are compact, portable, and produce accurate test pressures up to the rated maximum. Asada threading oils are formulated to lubricate cutting dies during threading, extending die life and producing cleaner thread finishes.

Where this product is used

Asada pressure test pumps are used wherever new or repaired pipework must be pressure-tested:

• Plumbing and gas fitting contractors testing water and gas pipe systems before commissioning.
• Fire protection engineers testing sprinkler system pipework to AS 2118 requirements.
• Industrial maintenance teams checking hydraulic and pneumatic line integrity after repair.

Selecting the right option

The TP50S manual pump (710 PSI / 3L tank) is suited to smaller systems and sites where a portable, no-power-required test solution is needed. The EP440 electric pump is the better choice for larger systems or high-volume testing where manual pumping is impractical. Select threading oil grade (standard or high grade) based on the material being threaded — high grade oil is recommended for stainless steel and harder alloys.
