UH310 Series differential pressure indicators and seal kits support accurate filter condition monitoring and reliable sealing performance. These components help operators maintain safe operation and optimize maintenance intervals in high-pressure hydraulic systems.
In high-pressure hydraulic filtration systems, condition monitoring and sealing integrity are critical to safe and efficient operation. UH310 Series differential pressure indicators and seal kits are designed to provide clear, reliable feedback on filter element condition, while maintaining pressure containment throughout extended service intervals.
Ayater supplies UH310-compatible monitoring and sealing components that match original installation dimensions and operating characteristics. These components are intended for long-term use in systems exposed to pressure pulsation, temperature variation, and continuous operation.
By enabling timely filter element replacement and preventing leakage, these accessories help protect downstream hydraulic components and stabilize overall system performance.
Differential pressure indicators measure the pressure drop across the filter element, providing a direct indication of contamination loading. As particles accumulate, pressure drop increases in a predictable manner, allowing operators to schedule element replacement before bypass conditions occur.
In UH310 systems, the use of a differential pressure indicator supports condition-based maintenance, reducing both premature element replacement and the risk of operating with a clogged filter.
For safety reasons, UH310 housings must be fitted with either a differential pressure indicator or a blanking plug prior to commissioning.
| Indicator Type | Material | Operating Pressure |
|---|---|---|
| Visual Indicator | Brass | < 200 bar |
| Visual Indicator | Stainless Steel | > 200 bar |
| Electrical SPDT Switch | Stainless Steel | > 200 bar |
| LED Visual Indicator | Brass | < 200 bar |
Standard indicator pressure setting is 3.5 bar (50 psid), providing a clear and repeatable signal when the filter element reaches its recommended service limit.
Electrical indicators allow integration with control systems for remote alarms and shutdown logic, while visual indicators offer immediate on-site confirmation without auxiliary power.
Seal performance is a critical factor in high-pressure filtration systems. The UH310 Series seal kit ensures reliable sealing between housing components under both static and dynamic pressure conditions.
Standard Seal Kit: SH310SKZ
Seal material: Fluorocarbon (FKM)
Operating temperature range: -29 °C to 120 °C
Fluorocarbon seals provide excellent resistance to hydraulic fluids, elevated temperatures, and pressure cycling, reducing the risk of extrusion, hardening, or leakage over time.
When no indicator is installed, a blanking plug HC9000A104Z must be fitted to replace the shipping plug and maintain pressure containment
Enables predictive and condition-based maintenance strategies
Reduces unplanned downtime caused by clogged filters
Protects pumps, valves, and actuators from contamination damage
Maintains pressure integrity in high-energy hydraulic circuits
These benefits are particularly important in applications where access is limited or shutdowns are costly.
