Pump Pressure Gauges

The ideal gauge features corrosion-resistant construction, such as 304 and 316 stainless steel, to endure continuous moisture and ambient vibrations. It should provide an easy-to-read display with appropriate connection sizes like 1/4 or 1/2 inch. Liquid fill options such as USP glycerin or silicone oil help stabilize internal mechanisms, ensuring dependable and steady pressure monitoring over extended service.

Normal operating pressure depends on system design, piping dimensions, and application requirements across water, chemical, or utility networks. For our industrial gauges, working pressure spans ranges from 15 to 200 psi. Maintaining system pressure within engineering parameters is vital; tracking regular gauge readings ensures early detection of abnormal conditions, line restrictions, or pump issues before major mechanical disruptions occur.

Pressure gauges are commonly classified by casing fluid styles: dry gauges and liquid-filled gauges. Dry units operate with no internal fluid fill, suitable for stable environments. Liquid-filled models utilize damping media such as USP glycerin or silicone oil. This liquid protects delicate internal movements from excessive vibration, mechanical pulse damage, and moisture, maintaining an accuracy rating of 1.6% FS.

Our industrial pressure gauges are manufactured using heavy-duty stainless steel alloys. The internal socket and sensing tube are crafted from 316 stainless steel for chemical and corrosion resistance. The outer case, bezel, and movement assemblies are produced from 304 stainless steel, ensuring structural integrity in challenging cooling, process water, and industrial manufacturing environments.

These instruments are offered in 2-1/2 inch or 4 inch case sizes to ensure clear visibility across varied mechanical rooms and equipment skids. Connection threading includes 1/4 inch or 1/2 inch sizing. Depending on your piping layout and clearance, gauges can be configured with either back or bottom mounting locations to fit your process piping.

Yes, our pressure gauges comply with applicable ASME and ASTM standards, as well as FDA requirements and 3-A sanitary guidelines where specified. Products are available with calibration documentation and material certifications upon request, ensuring compliance verification for regulated applications such as pharmaceutical, biotechnology, and food or beverage processing lines.
