1. General
Use
The MCP650 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 MCP650 pump is not submersible.
2. 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
an appropriate 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 (see permanent installation page
2).

Pump operating precautions:
The MCP650 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 particulate fillers will cause excessive wear
to the pump’s impeller bearing (see warranty note **).
Do not utilize small diameter or flow restrictive fittings in the pump inlet line. Minimum line inner diameter is 3/8”.
An example would be a
reservoir with ¼” fittings. This will cause the pump impeller to cavitate, lose prime, stop pumping and damage the pump (see warranty note ***).
Connecting the pump to the circuit:
The pump’s inlet and outlet are ½” in outside diameter. An optional adapter kit
is available to connect the MCP650 to a circuit using ½” ODx3/8”ID tubing. This
kit consists in:
1 foot
supply of ¾”ODx½”ID tubing and two reducers to make
the transition to the ½”ODx3/8”ID circuit.
TIP: when connecting the MCP650 pump to a ½”ODx3/8”ID circuit, always use
the longest possible ¾”ODx½”ID tube section at the inlet.
