Swiftech MCP655 User Manual

 General Use

The MCP655 pump is a magnetically driven centrifugal pump featuring a 12 V DC motor. It requires no maintenance when used with de-mineralized water and the appropriate anti-fungal additives. We recommend using 5% Swiftech’s HydrX™ as an additive. The pump is designed to be connected to your computer power supply using the standard Molex 4 pin connectors.

The MCP655 pump is neither submersible, nor selfpriming. The inlet needs to be continuously supplied with fluid for the pump to operate properly.

 Physical installation

 Determine the best location for your pump by

observing how the tubing will be routed to the rest of the circuit. Sharp bends in the tubing should always be avoided to prevent kinks, which will reduce or completely prevent flow of the cooling fluid.

 In general, we recommend installation of the pump

at the bottom of the chassis.

 The base of the pump features a soft neoprene pad

coated with strong adhesive material. Once the final location for the pump has been determined, simply peel-off the pad’s protective paper, and press the pump against the chassis surface. The surface should be clean, and non greasy. Thru-bolts are also provided for permanent installation, and require drilling holes in the chassis.

 The back of the pump features a potentiometer to

allow users to vary the pump speed from 1800 to 4800 rpm. Full speed is suggested for maximum performance. When reducing the pump speed, the operating noise will also decrease proportionally, but so will the performance. A flow rate chart is provided below

 Pump operating precautions:

The MCP655 pump should never be run dry, even for a quick test. You should always prime the pump with

fluid before you start operating it (see warranty note *).

Use of coloring die or fluorescent additives containing

Note: It is preferable to directly connect the RESERVOIR DISCHARGE to the PUMP INLET (no other components between pump and reservoir)

particulate fillers will cause excessive wear to the pump’s impeller bearing (see warranty note **).
