In response to the overwhelming demand for a quieter MCP650, Swiftech is proud to introduce the new MCP655 pump, which features several key improvements:

Considerably reduced audible operating noise: the high pitch frequency of the MCP655 is now eliminated thanks to a new chipset controllerHead and flow characteristics have slightly improved in the midrangeA potentiometer allows to adjust the pumps speed from 4800 rpm down to 1800 rpm. At 1800 rpm, the pump is virtually silent. This allows users to tune the pump performance/noise ratio to their particular preference.


Features:

The MCP655™ pump is 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 spherical 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.

Summary of benefits:

50,000 hours MTBF (Mean Time Between Failure) equivalent to 5 years lifetime.Superior 12 Volts DC convenience: plugs into the computer power supplyThe MCP655™ can be used with full confidence in any MP servers, and high-end workstations.Superior real world performance versus any aquarium pump we have tested to this date.The high pressure capability of the MCP655™ is particularly well adapted to high-flow systems using 1/2" ID or 3/8" ID Tubing.Compact Design.Quiet Operation even at high speeds thanks to the new chipset controller.1/2" barb fittings with 3/8" conversion system.No maintenance when used with de-mineralized water, and anti-fungal additives (Swiftech HydrX™ additive is recommended)Quick installation with adhesive neoprene pad, or permanent installation with thru-bolts.
