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).

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
***).
