GEP Fire

Your advantages

Modular certified system solution for individual requirements
Space-saving compact unit with minimum installation surface from 0.64 m² thanks to certified run-down tank with separator and free outlet (EN 1717)
Redundant lifting unit ensures hygienic safety is even possible when installed beneath the backflow level
Effective maintenance management and ongoing operating information

Design

Pressure boosting system for fire fighting in accordance with EN 1717, EN 12056, DIN 14462 or EN 12845 for indirect connection.

With 1 to 12 vertical, multiple stainless steel high-pressure multistage centrifugal pumps in glanded version with or without break tank and with or without housing.

Application

For fire fighting supply to exterior hydrants and fire hose reels, especially for high-rise buildings and large estates - without the use of pressure reduction valves - as well as sprinklers and water spray systems

Equipment/function

On baseplate, hydraulically and electrically ready-mounted pump system
Stainless steel multistage centrifugal pumps of the Helix V series
Stainless steel pipework (DIN EN 12502-1-5; DIN 50930-6)
Pressurised water connection with structure-borne noise insulation in the Victaulic system
Pump control of the pressure boosting system, pressure-dependent
The separating station completely automatically implements all measuring, switching and monitoring tasks. Display of all message texts such as function parameters or error messages via an external operating display
Drain or emergency drain (EN12056) for entire volume flow
Installation under the backflow level is possible
No pressure reduction valves in the main flow of the fire extinguishing systems
Effective maintenance management and constant information on operation via smartphone, tablet or PC

Construction

Baseplate: Hydraulic and electrical fully-assembled pump system, run-down tank, control, pneumatic valves with compressed air, structure-borne noise insulation, measuring instruments, emergency spillway
Pipework: Complete stainless steel pipework (DIN EN 12502-1-5 ; DIN 50930-6), suitable for the connection of all conventional piping materials; the pipework is dimensioned according to the overall hydraulic performance of the pressure boosting system
Pumps: Helix V series pump; all pump components in contact with fluid are made of stainless steel. For more information about the pump, please refer to the catalogue section "High-pressure multistage centrifugal pumps"
Monitoring connection: Control connection for function test of the pumps and actuators, especially for fire extinguishing systems, as no water is drawn off during most of the standby period
Stagnant water connection: Integrated stagnant water connection renews the water capacity in the drinking water single connection pipe based on the time and function parameters in accordance with DIN 1988, part 600
Pump control: Manual-Off-Auto switch, standard soft starter for single switching capacity over 4kW. Requirements-dependent activation and deactivation of the integrated pump, pressure-dependent control. For multi-pump systems in accordance with the speed control. Rotation connection for base load and peak load for achieving steady elapsed time figures.
Emergency operation pipe: Fuse protection of the pump minimum flow rate in accordance with DIN 14462
Safety valve connection: Drainage for expansion water in the event of a fire in accordance with DIN 14462.
Operating and error messages: Function check of the drinking water replenishment valve, function control steam pumps, overflow monitoring, dry running protection, optical operation and error message with clear text display
Building management systems: Potential-free contact for external fault signal
Run-down tank: Specially-developed run-down tanks made of stainless steel with free outlet in accordance with DIN EN 1717 for replenishment of high volume flows. Separator for reduction of gas input and reduction of the inflow speed integrated with run-down tank
Drinking water - replenishment Replenishment from public mains in accordance with DIN EN 1717 with free outlet type AB
Infiltration water supply: Infiltration water supply in industrial water pipe (e.g. via fire service) is permitted
Emergency drainage with overflow siphon: Upon cut in of the emergency spillway with integrated anti-syphon trap, drainage is performed in the underpressure system in accordance with DIN 12056, part 3
