  • Hand-held pressure generation
  • Low cost way to verify performance of pressure instrumentation
  • Rugged and reliable design
  • Fine adjustment control
  • Optional pressure relief valves
  • The most efficient pumps available – 4 strokes to 5,000 psi



Davis Instruments offers the best selection of hand-held, portable pumps – supplying pressure generation with standard fine-tuning adjustments and pressure relief valves. These pumps are ideal for use with electronic calibrators, digital indicators, analog gauges, pressure transmitters, transducers, relief valves, or simila instrumentation.

The rugged and reliable design of these pumps and the fine adjustment controls added to their design provide a low cost way to verify the performance of pressure instrumentation. Pumps can be purchased independently or in a kit including carrying case, NPT adapters, seals and hoses.

The SHTP1 hydraulic pump is currently the only hand pump capable of generating pressure up to 15,000 psi, utilizing hydraulic oil, Skydrol or distilled water. The pump includes a unique high pressure or priming selector on the scissor action pump mechanism, making pressure generation above 5,000 psi earlier.
