Products Description
Reliable Fire Safety
for High-Rise Buildings
The Wall Fire Pump Connector (SQB Series) is a critical fire protection device that connects fire trucks or mobile fire pumps to the building's internal fire water supply system. It ensures adequate water pressure for indoor fire pipelines, solving water supply challenges in high-rise buildings where internal pressure may be insufficient.
Designed for installation on exterior walls of factories, warehouses, docks, freight yards, high-rise buildings, and public spaces with dense populations, this connector provides a reliable interface for emergency firefighting operations.
High-pressure rated up to 2.5 MPa for demanding applications
Ductile iron body with brass components for corrosion resistance
Dual outlet design (KWS65×2 or KWS80×2) for flexible hose connections
Compact wall-mounted design saves ground space
Equipped with safety valve and drain valve for maintenance
Easy identification with clear markings and protective caps

What it is
A Reliable Connection When Firefighters Need More Water
Simple Access. High Pressure. Always Ready.
A wall fire pump connector is the interface that allows a fire truck or mobile fire pump to feed water directly into a building's fire protection system when the internal water supply or pressure is no longer sufficient. Installed on the exterior wall of a building, it provides firefighters with a fast, secure connection point to restore or supplement water flow to hydrants and sprinkler systems during an emergency.
Unlike active firefighting equipment, the connector contains no motors or control systems. Its durable ductile iron body, corrosion-resistant brass fittings, and integrated check valve ensure dependable operation after long periods of standby with minimal maintenance. The straightforward mechanical design makes it a reliable component in critical fire protection infrastructure.
The wall-mounted configuration is selected where ground space must remain unobstructed while providing convenient exterior access for emergency response. It is widely used on high-rise buildings, factories, warehouses, logistics centers, commercial complexes, and public facilities. Connection sizes, outlet configurations, pressure ratings, and thread standards can be specified to match local fire codes and project requirements.
How It Works
From pump truck to riser
Truck arrives
The fire truck or portable pump positions at the wall-mounted connector and connects its supply hose to the inlet.
Pump engages
Pressurized water is driven through the DN100 or DN150 inlet, sized to the building's fire flow demand.
Check valve opens
An internal non-return valve lets water pass into the riser while blocking backflow toward the street main.
Pressure restored
Water reaches the indoor fire main at full pressure, supplying sprinklers and hose cabinets on every floor.

Engineering Notes
Built for the one moment it matters
Design details that keep the connection ready between inspections.
Integral check valve
Prevents backflow into the street main and keeps the internal riser pressurized between pump strokes.
Standardized KWS coupling
Matches the fire brigade's storz-type hose couplings for a fast, tool-free connection under pressure.
Corrosion-resistant body
Brass or ductile-iron construction with protective coating for long-term exterior wall exposure.
Dual pressure classes
1.6 MPa and 2.5 MPa versions cover both standard and high-rise / high-demand piping systems.
Twin outlet capacity
Two KWS outlets per unit allow simultaneous hose connections to increase total supply flow.
Wall-fixed access
Permanently mounted at grade so responders can locate and connect without searching for buried hardware.
