Wilo-SiFire First

Design

Pressure-boosting systems for firefighting in accordance with EN 12845.

Depending on the model, composed of 1 horizontal base plate pump – EN 733 – with spacer coupling or cardanic joint, electrical or diesel motor and electrical multistage vertical jockey pump.

Application

Fully automatic water supply for fire-extinguishing systems with sprinklers in residential, commercial and public buildings, hotels, hospitals, department stores, and for office or industrial buildings.

Equipment/function

>       1 horizontal base plate pump per system from 32-200 to 100-200 series, with IE3 equivalent standard motor or diesel engine.

>       Diaphragm, to avoid over heating at zero flow, directly installed on the main pump housing.

>       Jockey pump from MVIL-1 series

>       One controller fixed on robust supports. Model E for electric motor and D for diesel engine, both equipped with a firefighing dedicated controller, plus additional control J for jockey pump, if present.

>       Electro galvanised steel base frame.

>       Pipe work made of steel and epoxy painted. Manifold with flanges.

>       Shut-off butterfly valve with security lock on discharge side of each pump.

>       Non-return valve, on discharge side of each pump.

>       One circuit with double pressure switch, manometer, non return valve, valve, for main pump for automatic start.

>       Concentric cone on discharge side on main pump, for speed limitation according to prameters requested in EN 12845 standard.

>       Connection DN 2" for the priming tank per pump.

>       Pressure gauge on discharge side.

>       Only for diesel engine model:

>       2 batteries on the base plate and battery chargers in the control box.

>       Separated fuel tank with level sensor and adequate volume to allow 6 hours operating autonomy.

>       Accessories on request:

>       Horizontal priming tank 500 L, with floating valve and pressure switch for low level alarm.

>       Flow meter

Materials

For horizontal base plate pump

>       Impellers made of Bronze CuSn10 or CuAl10Fe5Ni5

>       Wear rings made of AISI316L/1.4409 stainless steel

>       Pump housing made of cast iron EN-GJL-250

>       Shaft made of AISI420/1.4021 stainless steel

For Jockey pump

>       Impellers made of AISI304/1.4301 stainless steel

>       Pump housing made of cast iron EN-GJL-250

>       Shaft made of AISI304/1.4301 stainless steel

>       O-ring-seals made of EPDM

Construction

>       Base frame: Made of electro galvanised steel profiles, provided with brakets for control boxes. On the bottom part, special rectangular holes for forklift and integrated hooks for lifting straps.

>       Pipe work: Complete pipe work with flanges made of epoxy painted steel, suitable for connection of all commonly used piping materials; the pipe work is sized corresponding to the overall hydraulic performance of the pressure boosting system

>       Pumps: 1 horizontal base plate pump – EN 733 – with spacer coupling, electrical or diesel motor. Back pull out model for easy access to pump internal components without moving motor or pipes.

>       Fittings: For main pump, each pump is fitted on discharge side with a butterfly valve and non return valve, both with epoxy painted and adapted for flanged connection.

>       Tank: Separated fuel tank made of epoxy painted steel with leackage bacin.

>       Sensors and display: 2 Pressure switch 2/16 bar per pump located on the discharge side for activating the pump start through the control box controller. Discharge-side pressure gauge (ø 63 mm) located close to the pressure switches.

>       Control device/controller: The system is standard-equipped with control box for electric or diesel motor and a jockey pump controller, if present.
