Pressure gauge 0 - 25bar 1/8"

The 0-25 bar Ø50 mm 1/8" pressure gauge for the Kränzle Therm fuel pump is a measuring component designed for monitoring pressure in the fuel system of Therm series machines. In service practice, it is used to assess correct fuel pump operation and to diagnose problems related to unstable burner fuel supply.

MPN / reference: 44082
Measuring range: 0-25 bar
Dial diameter: Ø50 mm
Connection: 1/8"

APPLICATION

The pressure gauge is used in typical service and inspection work:

• pressure measurement in the fuel pump system,
• diagnostics of heating system problems in Kränzle Therm washers,
• checking parameters after repair or adjustment of the fuel system,
• replacement of a damaged or unreadable pressure indicator,
• inspection of machines where stable fuel supply operation is important.

SYMPTOMS - WHEN IT IS WORTH REPLACING

It is worth considering replacement of the pressure gauge when the following appear:

• no proper pressure indication,
• delayed pointer response or pointer “sticking”,
• unreadable scale or damaged lens,
• leak in the area of the pressure gauge connection,
• difficulty assessing fuel pump operating parameters during service.

HOW TO CHOOSE THE RIGHT PART

Selection of the pressure gauge should be unambiguous:

• verify the 0-25 bar range,
• confirm the Ø50 mm diameter,
• check the 1/8" connection,
• confirm the manufacturer number: MPN 44082,
• compare the mounting method with the removed part.

In fuel systems, compatibility of the range and connection is critical for reliable readings and correct diagnostics.

COMPATIBILITY

The pressure gauge should be selected based on MPN 44082, the 0-25 bar range, Ø50 mm diameter, and the 1/8" connection, according to the service documentation of the Kränzle Therm fuel pump system. The part should not be selected solely by the general description of a pressure gauge without checking the technical parameters.

[faq]

Why does this pressure gauge have a range only up to 25 bar and not 250 or 400 bar?|Because it is designed to measure pressure in the fuel system, not in the high-pressure water pump system. This is a completely different operating range and a different diagnostic area.

Does the Ø50 mm diameter matter when replacing it?|Yes. The diameter affects the mounting method, reading visibility, and fit to the location intended by the machine design or service panel.

Can an incorrect reading from this pressure gauge make heating system adjustment more difficult?|Yes. An incorrect reading makes it harder to assess fuel pump operation and can lead to incorrect diagnosis of burner fuel supply problems.

How can I tell whether the problem is with the pressure gauge itself and not the fuel pump?|If the readings are illogical, unstable, or the pressure gauge has visible mechanical damage, it is worth checking the gauge itself first. In service practice, the reading is often compared with another working instrument.

What should be checked after installing a new pressure gauge?|After installation, it is worth checking the tightness of the connection, stability of mounting, and whether the readings respond smoothly and correspond to the actual operation of the fuel system.
