Wheeler-Rex 47102 Hydro Test Pump Electric 1.1gpm 2000psi

SKU CH-N7SY-W10WN

Electric hydrostatic test pump delivers 1.1 GPM at 2000 psi with triplex piston design and adjustable relief valve

  • Electric motor delivers 1.1 GPM at 2000 psi for hydrostatic testing
  • Triplex piston pump with continuous oil bath lubrication ensures steady pressure output
  • Adjustable relief valve protects system by limiting maximum pressure to 3000 psi
  • Glycerin-filled 0-3000 psi gauge provides clear pressure reading during tests
  • Compact 28 x 17 x 35 inch frame with 10 ft hoses for job-site mobility

Hydrostatic Test Pump for Pressure Verification

The Wheeler-Rex 47102 is an electric hydrostatic test pump built for verifying the integrity of piping systems up to 2000 psi. It delivers a steady 1.1 gpm flow through a triplex piston, positive displacement mechanism. Plumbing contractors and maintenance crews use it for commissioning new installations or re-certifying existing lines.

Electric Motor Setup and Common Install Issues

The unit runs on a 200 V, single-phase, 60 Hz motor at 3450 rpm with a 5/8 in. shaft, so the site must provide that exact supply. A 10 ft inlet hose with 3/4 in. diameter and a 10 ft discharge hose at 1/2 in. are included, but both connect via 3/8 in. NPT ports. Installers sometimes overlook the required voltage or mismatch the NPT fittings, causing leaks or motor failure.

2000 psi Maximum Pressure Rating

The adjustable relief valve and glycerin-filled gauge read to 3000 psi, yet the pump’s rated ceiling is 2000 psi. That single figure decides whether the 47102 suits a given test spec; systems requiring higher proof pressures need a different pump. Continuous oil-bath lubrication supports sustained operation at this limit.

Questions about this item

How do I confirm the pump is reaching the rated 2000 psi during a test?

The glycerin-filled gauge reads 0 to 3000 psi; watch the needle stabilise at the target pressure while the adjustable relief valve holds it steady.

Which hoses and fittings are included with the 47102 and what must I supply?

The box contains a 3/4 in. x 10 ft. inlet hose and a 1/2 in. x 10 ft. discharge hose, both with 3/8 in. NPT connections; you provide the water source and any pipe adapters.

The spec lists 200 V single-phase 60 Hz — is that the only voltage option for this model?

Yes, the 1-1/2 HP motor is rated for 200 V, 1-phase, 60 Hz operation; no other voltage or phase configurations are offered for the 47102.
