The MCP355 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 and powerful motor make it ideally suited for extreme duty cooling in environments where space is at a premium. ***Specifications*** Nominal Voltage: 12 V DC, Operating Voltage: 8 to 13.2 V DC, Minimum Start-up Voltage: 9 V DC, Nominal Power (@ 12 V): 14 to 19W, Nominal Current (@ 12 V): 1.16 to 1.58 A, Nominal Head Pressure (@ 12 V): 15 ft (4.5 m), Nominal Discharge (@ 12 V): ~ 120 GPH (454 LPH), Connection Size : 3/8" barbs (10mm), Maximum (working) Pressure: 22 PSI (1.5 BAR), Temperature Range: Up to 140 °F (60 °C), Electrical Connector: Molex 4-pin, Weight: 7.3 oz (207 g), Noise Level: 30 ~ 32 dBA @ 2', Motor: Electronically Commutated Brushless, MTBF: 50,000 Hours, RPM Signal: Yes, RoHS: Compliant Review: Using this for a Pool Heater/Solar Water Heater - My dad purchased one of these pumps right around two years ago to install in his solar water heater system. He has about 12 feet of lift from the pump to the panels and it is running great. Runs right about a gallon per minute, which is perfect in solar heating applications. Works so well i purchased one for my solar pool heater. And i unwisely put it in a landscaping box in the ground too close to the pool and sure enough a few cannonballs too many and it flooded the box and the pump quite running. So i just purchased a second one and will be moving the installation further away but it is a great pump. Would highly recommend, if it will pump water 12 feet up (mine installation is only 11 feet of lift (head in pumping terms) and it runs 10-12 hours a day for two years i think any cpu cooling installation will work amazing for a long time. Review: Pump failed after a few hours. - The pump failed after a few hours of operation. Then to make matters worse the seller didn't respond to the returned package at all. So I had to go to desertcart. They of course fix the issue with a prompt refund. I bought this pump instead. It's not quite the same specs. But it may work for your application. http://www.desertcart.com/Solar-Water-Circulation-Brushless-Motor/dp/B00DWORE5A/ ## Features - 50,000 hours MTBF (Mean Time Between Failure) equivalent to 5 years lifetime. - Superior real world performance thanks to its high pressure characteristics. The MCP355 is particularly well adapted to the proliferation of daisy-chained liquid cooling devices in a single circuit: Multiple Processors, Chipset, Graphics, and Hard Drives - Superior 12 Volts DC convenience: plugs into the computer power supply - 3/8" barb fittings - RPM sensor plugs to 3 pin motherboard fan connectors and reports impeller rotational speed ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B005NJVX9K | | Brand | Swiftech | | Brand Name | Swiftech | | Customer Reviews | 3.6 out of 5 stars 8 Reviews | | Manufacturer | Swiftech | | Product Style | Submersible | | Specific Uses For Product | personal | | Style | Submersible | | UPC | 733886717303 | | Unit Count | 1 Count | | Voltage | 12 Volts, 13.2 Volts | ## Product Details - **Brand:** Swiftech - **Style:** Submersible - **Voltage:** 12 Volts, 13.2 Volts - **Manufacturer:** Swiftech - **UPC:** 733886717303 - **Specific Uses For Product:** personal ## Images ![MCP355 12v Water Pump (Native 3/8") (120 GPH) - Image 1](https://m.media-amazon.com/images/I/21kiGyqnwgL.jpg) ![MCP355 12v Water Pump (Native 3/8") (120 GPH) - Image 2](https://m.media-amazon.com/images/I/31OixIPK3pL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Using this for a Pool Heater/Solar Water Heater *by J***A on May 6, 2013* My dad purchased one of these pumps right around two years ago to install in his solar water heater system.
