Pressure indicators for ultra-high-pressure industrial tools

The LARZEP pressure gauges category in the HYDRON online store includes professional, industrial pressure indicators specifically designed to work in ultra-high-pressure hydraulic systems with an operating pressure of up to 700 bar (10,000 PSI). The LARZEP brand, part of the global Enerpac group, provides reliable measuring equipment dedicated to monitoring the load of cylinders, manual and electric pumps, presses, and hydraulic tools. LARZEP pressure gauges are equipped with robust stainless steel housings and factory glycerin filling, ensuring the highest level of measurement precision and resistance to harsh operating conditions in heavy industry, construction, energy, and technical services.

Key technical features and advantages of LARZEP pressure gauges

LARZEP hydraulic pressure gauges stand out with advanced design solutions that guarantee longevity and safety when operating 700 bar devices:

• Adaptation to extreme 700 bar pressures: The design of the Bourdon tube and internal components has been optimized for continuous operation at loads up to 700 bar (10,000 PSI).
• Damping glycerin filling: Filling the housing with pure glycerin effectively damps shocks, vibrations, and pressure pulsations generated by pumps, ensuring a stable reading and protecting the mechanism from wear.
• Clear dial with dual scale: A clear measuring scale graduated in bars and pounds per square inch (PSI) allows for quick and error-free control of operating parameters.
• Standardized NPT threaded connection: The bottom connection port with a 1/4" NPT thread enables direct mounting in pressure gauge connections, distribution blocks, and hydraulic pumps.

Wide application in diagnostics and control of 700 bar systems

LARZEP pressure gauges are commonly used for routine monitoring of force and pressure in hydraulic systems. They work with LARZEP and Enerpac manual, air-hydraulic, and electric pumps that power single-and double-acting cylinders, bearing pullers, torque wrenches, nut cutters, and workshop presses. Constant pressure monitoring prevents component overload and increases operator safety.

Frequently Asked Questions (FAQ)

Why is glycerin filling used in LARZEP industrial pressure gauges?

Liquid glycerin filling the inside of the housing eliminates vibrations and needle jumps caused by oil pulsation and machine vibrations. Thanks to this, the pressure reading is smooth and accurate, and the delicate gears of the mechanism are protected from premature wear.

Which adapters do LARZEP pressure gauges with 1/4" NPT thread work with?

These pressure gauges are most commonly mounted in special pressure gauge connections (e.g., Larzep AZ1502) connected between the pump and the pressure hose, or screwed directly into the bodies of pumps and distribution blocks equipped with a 1/4" NPT socket.
