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
the computer power-supply with a 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.
The MCP655 is available in two versions:
- With a speed controller (part # MCP655)
- Without speed controller (part # MCP655-B)
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 supply
- The MCP655 can be used with full confidence in any MP
servers, and high-end workstations.
- Superior real world performance
- High pressure capability of the MCP655 is particularly
well adapted to high-flow systems using 1/2" ID tubing
- Pump speed can be adjusted to yield top performance or virtually
silent operations (model MCP655 only)
- Compact Design.
- Quiet operations even at high speed thanks to new chipset
controller
- ½" Barb fittings.
