Hydraulic Pressure Comparison Test Pump upto 7000 bar

Model LR-Cal LSP 4000

• Generation of pressure up to 4000 bar
• Simple hydraulic test pressure generation on site, in the laboratory or in the workshop
• For testing, adjustment and calibration of all types of pressure measuring instruments
• Hydraulic pressure generation up to 4,000 bar (58,000 psi)
• Precisely adjustable dual-area spindle pump for filling, pressure generation and fine adjustment of pressure
• Compact dimensions, low weight

The LR-Cal LSP 4000 serves as pressure generator for the testing, adjustment and calibration of mechanical and electronic pressure measuring instruments through comparative measurements. The device can be used in the laboratory or workshop, or on site at the measuring point.

By connecting the test item and a sufficiently accurate reference pressure measuring instrument to the test pump, the same pressure will act on both measuring instruments. By comparison of the two measured values at any given pressure value, a check of the accuracy and/or adjustment of the pressure measuring instrument under test can be carried out.

The integrated dual-area spindle pump with switching valve enables rapid filling of the test system and smooth pressure generation.

At the same time, the precisely adjustable spindle pump also serves for fine pressure adjustment. A control schematic for pressure generation on the instrument base facilitates quick and easy operation.

The two test connections are equipped with 1/2" BSP female loose union connections with double ended metal cone. Two threaded adapters mounted on M16x1.5 male thread are included in the scope of standard delivery. Further thread adapters are available for the calibration of instruments with different connection threads.

Model LR-Cal LSP 7000

• Generation of pressure up to 7000 bar
• Hydraulic pressure source for calibration purposes, up to 7000 bar
• Operatinf fluid: special high pressure hydraulic fluid (mineral oil based)
• With integrated priming pump
• Also high pressure values are generated by operation of the spindle pump, with one run, without switching anything
• Robust metal housing

The pressure comparison pump LR-Cal LSP 7000 is used to generate pressure for calibration purposes, for checking and calibration of any kind of pressure instruments in the laboratory as well as in the field, by means of comparison.

When the device under test and a reference measuring instrument with an adequate accuracy are connected to the test pump, the same pressure will act on both measuring instruments after actuating the pump. A calibration or an adjustment can be carried out by comparing the two measured values at any pressure value.

In order to enable an accurate generation of the measuring points, the pressure comparison pump LR-Cal LSP 7000 is provided with a fine adjustable spindle pump. In addition, the LR-Cal LSP 7000 feature a spindle which only runs withing the pump body. Thus there is no adverse bending moment acting on an outstanding spindle, and particularly for field use this has the advantage that the dimension of these pressure comparison pumps will not change when the spindle is turned during operation. The LR-Cal LSP 7000 needs only little force to generate also high pressures.
