Comparison Test Pumps 

High pressure-spindle pump for calibration purposes

Model LR- Cal LSP 7000-HP

  • Pressure Source for calibration, hydraulic, pressure up to +7000 bar
  • Operating liquid: special high-pressure-suitable hydraulic liquid on mineral oil basis
  • With built-in booster pump
  • Also high pressures leave themselves generate via the spindle pressures without great expenditure of force and finely adjust, not a pressure converter or similar required
  • Execution in a sturdy metal housing

Description LR- Cal LSP 7000-HP Druckvergleichsprüfpumpe


The Pressure Comparison Test Pumps LR- Cal LSP 7000-HP used to generate pressure for testing, adjusting and calibrating mechanical and electronic pressure measuring instruments by comparative measurements of all kinds. These pressure tests may be in the laboratory or workshop, but also on site to take place at the measuring point.

If you connect the pressure gauge to be tested and a sufficiently accurate reference pressure gauge to the Druckvergleichsprüfpumpe LR- Cal LSP 7000-HP on, acts upon actuation of the pump, the same pressure on both gauges. By comparing the two measured values ​​at any pressure values ​​can be a review of the accuracy or an adjustment of the instrument under test.

For the exact start of the measurement points, the Pressure Comparison Test Pumps (screw pumps) are LR- Cal LSP-HP 7000 equipped with a fine to be operated spindle wheel. The devices are characterized by a current within the pump body rotating spindle, so that there is no adverse bending torque on a spindle and particularly for mobile applications also has the advantage that the size of the Test Pumps not changed during operation by turning the spindle. The Pressure Comparison Test Pumps LR- Cal LSP 7000-HP only need a very little effort, you can also reach 7000 bar without pressure converter, so just by directly screwing the spindle.
