  • Hand-held pressure or vacuum generation
  • Low-cost way to verify performance of pressure instrumentation
  • Rugged and reliable design
  • Fine adjustment control
  • The most efficient pumps available

These pumps are ideal for use with electronic calibrators, digital indicators, analog gauges, pressure transmitters, transducers, relief valves, or similar instrumentation.

The rugged and reliable design of these pumps and the fine adjustment controls added to their design provides 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 easier.

The STP1 pneumatic pump generates pressure to 600 psi and vacuum to 28”Hg on the same unit. Made with no plastic parts these pumps are designed to endure harsh environments unlike our competitor’s disposable models.

The SLTP1 pneumatic pump also acts as a dual source of pressure and vacuum over smaller ranges making very fine adjustments easier. The SLTP1 range is 25”Hg vacuum to 30 psi, with 0.00145 psi sensitivity.

  • Q:

    i have a TP1-40, but now it can not have over 6 bars.
    Can you help us for a solution of this problem
    Asked on 8/16/2010 by rufisque from dakar

    1 answer



      This unit is rated for 40 bar; if you can get only 6 bar there is clearly a leak somewhere. Remove the fittings and gauge, test the gauge on another pump to ensure it works properlly without any leaks, then clean the ports and plug them. Install the gauge, pump up the pressure and observe. If you still cannot reach 40 bar then either rebuild the pump yourself using the service kit or return it to your dealer for repair.
