Product Description
John Crane Single Mechanical Seal Water Station – Commissioning, Maintenance & Barrier Fluid Selection
About Dongguan HydroBlue Co., Ltd.
DONGGUAN HydroBlue CO.,LTD. operates as a technology-focused enterprise offering full-spectrum technical solutions across fluid machinery, fluid engineering, industrial automation, and power conversion systems. Our 8-strong engineering team brings together expertise in fluid mechanics, electrical engineering, and electronic engineering to bridge the gap between R&D and commercial production. Ongoing joint development with Jiangsu University, Chinese Academy of Sciences, and Guangdong University of Technology ensures our processes and products stay ahead of industry requirements worldwide. Jiangsu University National Research Center of Pumps provides seal water station pressure and flow modeling for John Crane single seal support systems under varying pump operating conditions to ensure stable seal face cooling and lubrication; Chinese Academy of Sciences develops advanced barrier fluid filtration technology and microbiological growth inhibitors for seal water stations handling non-potable water or open-loop cooling systems; Guangdong University of Technology supports IoT-enabled remote seal water station monitoring platform development for real-time pressure, temperature, and fluid level tracking with automated maintenance alerts.
Let us know the pump model and John Crane seal specifications you require — our engineers will cross-reference compatibility and respond with a professional technical assessment.
OUR BRANDS & SERVICES
Our proprietary brand provides complete technical solutions across the fluid machinery and engineering spectrum. Supported by our suite of proprietary technologies and product brands, we provide clients with premium technical consultation, sales assistance, and bundled system solutions — covering pumps, frequency converters, servo drives, PLC-HMI, industrial control cabinets, motors, mechanical seals and systems, couplings, gearboxes, and comprehensive engineering project services (overseas on-site 3D scanning reverse molding of pump replacement parts, and field debugging by our dispatched engineers internationally).
Installation & Commissioning Guide
- Mount the Reservoir — Position the water station above the seal chamber to utilize natural thermosyphon circulation; the minimum vertical height difference between the water station outlet and the seal chamber should be 300 mm for reliable natural circulation
- Connect Supply and Return Lines — Connect the supply line (from water station bottom outlet to seal chamber lower port) and the return line (from seal chamber upper port to water station top inlet). Use short, direct runs with minimal bends to reduce flow resistance
- Connect Cooling Water Supply — For water-cooled coils, connect the cooling water inlet and outlet. Cooling water should be clean, filtered, and at a temperature at least 10°C below the barrier fluid target temperature
- Fill & Vent the System — Fill the reservoir with the specified barrier fluid to the fill line. Open the vent valve at the top of the reservoir and bleed all air from the supply and return lines. Close the vent valve when a steady stream of fluid appears
- Pressure Check — For pressurized plans, introduce nitrogen or inert gas to the reservoir headspace to the specified pressure (typically 1–3 bar above the seal chamber pressure). Verify no leaks at fittings, gauge connections, or the reservoir vent valve
- Start Pump & Monitor — Start the pump and observe the barrier fluid return temperature. A stable temperature within 10–20°C of the cooling water inlet temperature indicates proper circulation. If the temperature rises continuously, check for air locks in the circulation lines or insufficient cooling water flow
Barrier Fluid Selection Guide

Compatibility |
Typical Application |
|---|---|---|---|---|
|
Clean water (treated) |
5–90°C |
0.65 |
Elastomer NBR/EPDM/FKM; no precipitates |
General water pumps, cooling towers, HVAC |
|
Water + glycol (30–50%) |
-20°C to +90°C |
2.5–5.0 |
EPDM (not NBR); check elastomer compatibility |
Cold climate, freeze protection in outdoor installations |
|
Light mineral oil |
-10°C to +150°C |
10–30 |
FKM elastomer; not compatible with NBR |
High-temperature water, hot process, boiler feed |
|
Water + anti-corrosion inhibitor |
5–95°C |

All standard elastomers; protects SS 304/316 wetted parts |
Seawater pumps, cooling water with high chloride content |
Routine Maintenance Schedule
|
Interval |
Check Item |
Action Required |
|---|---|---|
|
Daily (visual) |
Reservoir fluid level (sight glass) |
Top up if level is below minimum line; investigate cause if consumption is abnormal |
|
Monthly |
Cooling water flow rate and temperature |
Check cooling water supply is at design flow; clean strainer if flow is reduced |
|
Quarterly |
Barrier fluid clarity and pH |
If fluid is discolored, cloudy, or contains particles, drain, flush, and refill; test pH per manufacturer specification (6.5–8.5 for water-based fluids) |
|
Semi-annual |
Pressure gauge calibration |
Verify gauge reading against reference; replace if deviation exceeds 5% of full scale |
|
Annual |
Full system drain, clean, and inspection |
Drain barrier fluid; disassemble and inspect reservoir interior for scaling, corrosion, or sediment; clean cooling coil; replace O-rings on sight glass and fill cap |
|
Annual |
Cooling coil integrity |
Hydrostatically test cooling coil at 1.5× operating pressure; repair or replace if leaks are detected |
Troubleshooting
|
Symptom |
Likely Cause |
Corrective Action |
|---|---|---|
|
Barrier fluid temperature increasing during pump operation |
Insufficient cooling water flow; air lock in circulation lines; cooling coil fouled |
Check cooling water supply valve; vent circulation lines; clean cooling coil with descaling solution |
|
Rapid fluid loss from reservoir |
Seal face leakage (process fluid entering barrier fluid or barrier fluid escaping past seal); external leak at fitting |
Check barrier fluid for process fluid contamination; tighten all compression fittings; if seal leakage confirmed, schedule seal replacement |
|
Fluid level rising (water station overfilling) |
Cooling coil leak: cooling water entering barrier fluid; or seal leakage: process fluid entering barrier fluid |
Isolate cooling water; if level stops rising, cooling coil is leaking — replace coil. If level continues rising, seal is leaking process fluid into barrier fluid — replace seal |
|
No circulation observed (supply line cold, return line cold) |
Air lock in piping; reservoir mounted too low relative to seal chamber; circulation path blocked |
Vent system at highest point; confirm reservoir outlet is at least 300 mm above seal chamber top; check for blockages in supply and return ports |
|
Pressure gauge fluctuating rapidly |
Gas entrainment in barrier fluid; pump pressure pulsation transmitted to seal chamber |
Vent gas from reservoir headspace; check pump suction conditions; if pulsation is severe, install a pulsation dampener on the circulation line |
