Complete Fire Hydrant Range — Made In-House
Complete Fire Hydrant Systems for Municipal & Industrial Networks
Wanlian Fluid manufactures the full fire hydrant range — indoor SN65 hydrant heads, overground SS100 hydrants, SSFT100 anti-collision hydrants and SS100ZN IoT smart hydrants — with export connection standards (BS336, NIST, KWS) and matching couplings, all produced on our own production lines for the whole hydrant network.

Frequently Asked Questions
What is the difference between indoor and outdoor fire hydrants? +
Indoor hydrants (SN65 head) connect to building standpipe systems and feed hose stations on each floor. Outdoor hydrants (SS100 ground type) draw from municipal or industrial mains and supply fire engines and external firefighting. The two serve different distribution points and are specified against different codes.
What outlet connection standards are available for export hydrants? +
Common outlet connections include BS336 (UK/Commonwealth), NIST (Middle East), KWS (Germany) and flexible flange options. Wanlian manufactures SS100/65 and SSFT100/65 hydrants with the connection type specified for your market, and can ship matching couplings and adapters in the same container.
Are Wanlian hydrants available with UL or FM certification? +
Yes, depending on the model and destination market. Contact our sales team with your project specification and target region so we can match the correct certification package — UL/FM for North America, CE for Europe, LPCB for UK/Commonwealth projects.
Which hydrant should I choose for a cold-climate city? +
The SS100 overground hydrant features an automatic post-closing dry-barrel drainage mechanism that prevents freezing and barrel rupture — the standard choice for municipal networks in cold regions. For traffic-exposed locations, the SSFT100 anti-collision variant adds a breakaway body and pressure regulation.
Can smart hydrants integrate with our SCADA system? +
Yes. The SS100ZN IoT hydrant transmits pressure, tilt and valve-status data via NB-IoT/LTE-M/GPRS and integrates with standard SCADA platforms. Request the data interface spec and a sample device for integration testing before ordering.
