Wheeler-Rex

Wheeler-Rex 32300 pneumatic test pump 1.0 GPM 3/4 in intake

SKU CH-0CT6-6042F

Pneumatic test pump delivers up to 1.0 GPM flow and 3,000 psi discharge pressure with adjustable relief valve

  • Reciprocating plunger design delivers up to 3,000 psi discharge pressure
  • 0 GPM maximum flow rate for efficient system testing
  • Adjustable relief valve provides precise pressure control during operation
  • 75 cfm maximum air consumption at 100 psi intake pressure
  • Compact 14 x 19 x 9 in footprint fits tight workspaces

Purpose-built pneumatic tester

The Wheeler-Rex 32300 pneumatic test pump generates up to 3,000 psi discharge pressure with a 0.5 gpm flow rate. It uses a reciprocating plunger design driven by compressed air at up to 100 psi and 75 cfm. The unit measures 14 in long, 19 in wide and 9 in high.

Suited for pressure testing.

Plumbers and mechanical contractors can use it for hydrostatic testing of pipe runs, vessels and fittings where adjustable relief-valve control is required. It is not intended for continuous high-flow transfer jobs that demand more than 0.5 gpm or for applications needing electric or hydraulic drive.

Connections and relief valve shape the workflow

A 3/4 in GHT intake and 3/4 in JIC air inlet let the pump connect to standard garden-hose and air-supply fittings. The 1/4 in MNPT discharge port threads directly onto test gauges or hose assemblies. The adjustable pressure relief valve lets the operator set a precise test pressure without external regulators.

Questions about this item

What size air hose fitting do I need to connect to the 3/4 in JIC intake on the Wheeler-Rex 32300?

You need a hose or adapter with a 3/4 in JIC male fitting to match the pump's air intake connection.

Will the 1/4 in MNPT discharge on this pump thread directly into my existing 1/4 in NPT test gauge?

Yes, the 1/4 in MNPT discharge connection is designed to thread straight into a standard 1/4 in NPT female port on a gauge or hose.

How can I confirm the pump is hitting the 3,000 psi maximum discharge pressure during a test?

Watch the connected pressure gauge; when the needle stops rising at the set relief-valve pressure, the pump is delivering its rated output.
