Introduction
The MCP35X™ pump is a substantial evolution from the long established MCP355 series. It differentiates itself from its sibling by two primary features:
- The pump housing:
- has been redesigned to provide considerably enhanced hydraulic performance;
 
- is compatible with multiple tubing options thanks to the adoption of the G1/4 port standard;
 
- can host an optional "built-in" reservoir;
 
- is also sold separately, and remains compatible with all MCP3XX series pumps
 
 
- The motor:
- is now PWM compatible, allowing variable speed control thru the motherboard from 1300 to 4500 rpm.
 
 
Summary of features and benefits
- Small Footprint: 2.4" x 2.4" x 1.36";
 
- 50,000 hours MTBF (Mean Time Between Failure) ;
 
- 12 Volts DC convenience: plugs into the computer power supply
 
- Variable speed control via PWM thru the motherboard, from 1300 rpm for completely silent operation, to 4500 rpm for ultra high flow performance;
 
- Superior head pressure and flow rate (in the useable range) to any pump in its footprint: the MCP35X™ is particularly well adapted to support multiple devices in the same loop, such as multiple radiators, and/or waterblocks;
 
- G1/4" ports standard for compatibility with a large assorment of fittings;
 
- No maintenance when used with distilled water, and anti-fungal additives (our HydrX™ additive is recommended);
 
- Quick installation with adhesive neoprene pad, or permanent installation with supplied hardware;
 
- Optional "built-in" reservoir;
 
- 2 year warranty
