Comparison Test Pumps 

High pressure-spindle pump for calibration purposes

Model LR- Cal LSP 3000-HP

• Pressure Source for calibration, hydraulically, Pressure-/Vacuum-generation to +3000 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 3000-HP Druckvergleichsprüfpumpe

The Pressure Comparison Test Pumps LR- Cal LSP 3000-HP serves for pressure generation for checking, adjusting and calibration of mechanical and electronic pressure meters of all sorts by comparison measurements. These pressure tests may be in the laboratory or workshop, but also on site to take place at the measuring point.

Closes you the to be tested pressure measuring instrument and a sufficiently-accurate reference pressure meter at the Druckvergleichsprüfpumpe  LR- Cal LSP 3000-HP at, so acts after actuating the pump on both measuring instruments, the same pressure. 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 exact approach of the measurement points that Pressure Comparison Test Pumps (spindle pumps) are  LR- Cal LSP 3000-HP equipped with a finely to be actuated 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 3000-HP only need a very low force effort, you reach also 3000 bar without pressure converter, ie simply by directly screwing in the spindle.
