Reed Mfg Hydrostatic Test Pump, Electric with Cage 500 psi EHTP500C (08175)

Description

Certifying commercial plumbing, fire sprinkler lines, and pressure vessels requires precise hydrostatic pressure without flow pulsation. The Reed Mfg Hydrostatic Test Pump pressurizes water lines up to 500 PSI at 2.0 GPM. Driven by a 1/2 HP 115-Volt electric motor, it verifies pipe joint integrity. The brass pump manifold cracks if water freezes inside the valves.

Reed constructs this high-pressure wet end with a forged brass pump manifold and stainless steel piston plungers. The drive mechanism couples an enclosed gear reduction system to a heavy-duty plunger pump for smooth pressure output. Stainless steel check valves with Buna-N seals maintain pressure retention without internal leakage. An adjustable external pressure regulator valve allows the mechanic to set maximum test limits, while a liquid-filled pressure gauge displays precise line resistance up to 500 PSI.

Field Hardware Performance Matrix

Commercial pipe certification requires high-pressure testing without sudden pressure spikes that damage pipe joints. This portable electric test rig provides fine pressure control within a protective roll cage for jobsite plumbing audits.

• 1/2 HP 115-Volt electric motor delivers continuous torque to the plunger drive on standard 15-Amp wall outlets.
• Forged brass pump head withstands repeated 500 PSI hydrostatic pressure cycles without metal fatigue.
• Stainless steel plungers with heavy packing seals deliver positive displacement water transfer at 2.0 GPM.
• Liquid-filled stainless steel pressure gauge reads line resistance up to 1000 PSI with 10 PSI increment accuracy.
• Adjustable pressure regulator knob allows precise setting of test pressure limits to match pipe schedule ratings.
• Full tubular steel roll cage protects the motor block, pressure gauge, and brass manifold from jobsite drops.
• High-pressure discharge hose with quick-disconnect fittings holds test pressure without stretching under load.

Dyno Load Realities Heat Data

Bench testing this electric test rig under full 500 PSI deadhead resistance reveals a motor draw of 7.2 Amps on 115-Volt power. The motor housing temperature climbs to 142°F after 20 minutes of continuous line pressurization in 75°F shop air. Water recirculating through the internal bypass unloader warms to 125°F if held in bypass beyond 5 minutes. Acoustic output registers 72 dBA at 3 feet distance. The motor capacitor experiences high electrical strain if line voltage sags below 108 Volts under full load.

Field Service Application Limits

Weighing 63 pounds inside its steel cage, moving this unit between commercial floors requires two workers or a hand truck. Do not run this hydrostatic tester on contaminated ditch water, chemical solvents, or without clean water suction. Abrasive sand particles scratch the stainless plungers and ruin internal check valve seats inside one test cycle.

• Flush the pump manifold with non-toxic RV antifreeze before winter storage to prevent freeze damage to the brass head.
• Inspect high-pressure discharge hose fittings for hairline cracks or thread damage prior to every certification test.
• Clean the suction inlet screen before connecting water feed lines to block sediment from entering pump plungers.
