1. General
Use
The MCP350™ pump is a magnetically
driven centrifugal pump featuring a 12 V
DC brushless 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. Effective 1/24/05, the pump
features a second wire equipped with a
3-pin connector designed to connect to
a motherboard fan header, and to
report the impeller rotational speed
(RPM sensor).
The MCP350™ 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.
Screws & grommets are also
provided for permanent
installation, and require drilling
holes in the chassis (see
permanent installation page 2).
3. Pump
operating
precautions:
The MCP350™ 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 *). With filled lines, turn
the inlet/outlets upward to ensure there
is no air bubble in the impeller.
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 may cause the pump impeller to cavitate, lose prime, stop pumping and damage the pump (see warranty note
***).
