What i need is a 24Vpump, similar to SWIFTECH MCP350 pump, not exact. Now i can only give you features and specification of 12V pump:  feature: despite a remarkably small footprint of 2.4" square, the MCP350 features an astounding 13ft of head to provide superior flow rates in today's most complex liquid cooled systems. The MCP350 is also a high reliability, high pressure industrial pump, featuring a 50,000 hour MTBF (5 year lifetime). Such reliability is afforded by the unique design of this pump, which contains only one moving part: the magnetically driven rotor/impeller spins on a single ceramic bearing, thus extending the life of this pump beyond existing standards.  The pump is completely plug-and-play, and connects directly to any computer power-supply through standard 4 pin power connectors. It's compact design, quiet and powerful motor make it ideally suited for heavy duty cooling in environments where space is at a premium.  technical specification: Nominal voltage12 V DC Operating voltage range 8 to 13.2 VDC  Minimum startup Voltage 9 VDC  Nominal power (12 V) 8.3 to 12 W Nominal current (12 V) 0.69 to 1 A  Nominal head (12 V)10.8 ft (3.3 m) Nominal discharge ( 12 V)- 1.16 GPH (440 LPH) Connection size3/8" barbs (10mm) Maximum pressure 22 PSI (1.5 BAR)  Temperature range Up to 140F (60C)  Electrical connector Molex 4 pin Weight 7.3 oz (207 gr.)
