High Flow Ratio Ejector Pump

Submersible ejector pump works in the same manner as Turbine pump and offers the same advantages.

Submerged High pressure recovery ejector pump utilizes the available high pressure water injection (WI) know as primary flow which creates the suction of sea water called secondary flow and it further combines both flows to help extinguish fire at the platform.

High pressure water injection known as primary flow is injected to the ejector's nozzle at which venturi effect is created where suction of sea water also known as secondary flow takes place and further enters into the pump through the strainer.

The suction of secondary flow is in multiple times to that of primary flow.

Key Benefits

Automatic firefighting system which does not need human intervention to operate.
No maintenance required
No diesel or electric power required
Ability to reverse flow for cleaning pump's strainer
Can be used as a utility water pump
Submerging below 20 meters of sea level keeps the pump Risk-free from fire
No moving parts
No lubrication system required

How it works?

As soon as fire takes place, the Fire shutdown panel which is currently existing in offshore unmanned platform gives signal to our control panel.
Control panel opens blow down valve (BDV) and deluge valves (DV) simultaneously.
As soon as BDV & DV gets open, the pressurized water from water injection line enters the inlet of pump. The pump reduces the pressure while increasing the flow of secondary flow from sea water by means of its suction and discharges the combined flow to extinguish the fire.
The discharge flow travels through the fire-water header to the fire loop -1 or 2 at platform’s Deck.
The pressure control valve controls the pressure flowing in the water inlet line.
