The Transmation 6215P Pressure Pump generates up to 145 psi on a dead-end circuit

It features a vernier adjustment knob for fine-tuning, and a manually controlled bleed valve for controlling venting.

The pumps are tube type, cylindrical shaped hand pumps with a “T” handle at the compressor end and a round knob at the volume adjust end. The overall length is between 11.5″ (full extension) and 8.5″ (fully collapsed). They incorporate a needle valve for venting and a volume adjust vernier for precision adjustment of pressure.

Pressure or vacuum connections are made through one 1/8″ NPT internally threaded fitting. The pump is small in size, lightweight and ruggedly constructed to withstand typical field use.
