Require rather urgently a rule of thumb for costs of seawater lift
pumps complete with electric motor driver.  Pump will consume 1.9MW
(about 2548 HP) of energy. Type: vertical wet pit pumps to API
standards.  Volume of seawater to be pumped is 10,000m³/hour. 
Discharging into a 60inch (1524mm) diameter pipeline for delivery to a
plant 1400 meteres from the pump.

Due to urgency am prepared to accept an indicative price for the pump
plus drive OR a rule of thumb costs per Horsepower for pump plus costs
per horsepower for the electric drive would be very useful.

So limited research should be all that is needed.

Need reply by Monday 17 May (UK time).  Thereafter not of much use.

There are few companies in the world that make vertical turbine pumps
this large.  I would look in your phone book or at www.gouldspumps.com
for your local Goulds representative.  They have a vertical turbine
pump that will pump up to 440,000 gpm (gallons per minute)  Your local
dealer will gladly budget it, just to have a chance to sell it to you
in the future.  (It may take the dealer a few weeks since the motor is
a behemoth. I have been selling Gould for over a decade, and have
never quoted one of these)  Good luck!
