High Pressure Portable Hydrostatic Test Pumps, 938-9 Series
These hydro test pumps are a fast, safe, and simple method for hydrostatic testing, ideally suited to work with these plugs (145-1, 145-9, 146-9, 147-1, & 151) or on a stand-alone basis. Choose from two high pressure styles of hydrostatic test units or lower pressure manual and electric test units.

A-Style Hydrostatic Test Pumps
- Ideal for hydro testing heat exchanger tubes, pipes, and pressure vessels
- Test in the field or in the shop
- Simple air-driven pump
- Output pressures range from 1,000 to 10,000 psi (69 to 690 bar)
- Self lubricating air over water intensifier
- Hydro test products with water supply connection
- Easy to read 4" (100 mm) diameter pressure gauge
- Regulator to control inlet air supply
- High pressure bleed valve and high pressure outlet
- Equipped with 10 ft (3.1 m) high pressure hose with quick couplings
- Mating quick connect couplings for air, water inlet connections, and high pressure outlet
- Lockable aluminum tool box with room for hose, fittings, and plug
B-Style Hydrostatic Test Pumps
- Ideal for all hydrostatic testing
- Slightly larger pump mounted on a hand truck
- Hydro test products with simple air-driven pump
- Built-in filter, regulator, and lubricator on air inlet
- Output pressures range from 1,000 to 10,000 psi (69 to 690 bar)
- Easy to read 4" (100 mm) diameter pressure gauge
- High pressure system bleed valve
- Water suction strainer with crow's foot connector
- Supplied with 15 ft (4.5 m) high pressure hose with swivel
- Heavy duty enclosure with integral wheels and handle for portability
*Total required CFM to produce rated flow at maximum pump pressure. This is relevant only when the system is used for continuous injection at the maximum rated pressure. Normal testing applications require much less CFM to begin with and fall to (0) at stall test pressure.
