PMUP – INTRODUCTION
The PMUP is a 24VDC fixed-speed submersible multipurpose pump that can be used for
many different tasks on your aquarium. The PMUP directly connects to the DC24 accessory
ports on either the 1LINK module -OR- the DC24 ACC ports on the new Energy Bar 832. Its
most popular uses will be:
•Automatic Top-Off (ATO)
•Carbon reactors
•GFO reactors
•Biopellet reactors
•Many other salt or freshwater uses
The specifications of the PMUP are:
•24VDC
•17 watts power consumption
•100GPH @ 0 head
•14 feet maximum head
•Dimensions – 4.58″ x 2.24″
•Power cable length: 6.5’ / 2m
The PMUP is intended as an accessory for use with any Apex aquarium controller equipped
with either an Energy Bar 832 or a 1LINK module. An Apex and an EB832 -or- an Apex
and 1LINK module are required.
An optional 10’ / 3m extension cable is available; the Neptune Systems part number is
CBL-DC24-EXT.
PLUMBING YOUR PMUP
The output tube of the PMUP is 3/8” in diameter, and may be used with 3/8” quick
disconnect fittings or 3/8” ID flexible tubing.Tubing and quick-disconnects are not
included with the PMUP.
Neptune Systems recommends the use of quick-disconnect fittings (3/8”-3/8” female-
female or 3/8”-1/4” female-female) and polyethylene tubing (commonly called RO/DI
tubing in the hobby) or polyurethane tubing as illustrated here:

If 3/8” ID tubing is used, it is recommended that silicone tubing be used versus vinyl or
polyethylene tubing. Silicone tubing will grip the PMUP’s output tube securely without the
need for a clamp.

Optionally, an inline valve may be used to reduce flow, such as may be desirable when used for
feeding some reactors.
PHYSICAL INSTALLATION
WARNING: The PMUP must be submerged in water during operation. It must
not be run dry. If oriented vertically, the water depth must be at least 2”. If
oriented horizontally, the water depth must be at least 2.5”.

CAUTION: The PMUP is intended for use in relatively clean water. It must not
be used in an area where sand or other debris could be drawn into the PMUP. If
sand or other hard debris enters the pump, it may fail; this will not be covered
under warranty.
The PMUP is intended for submerged use at the bottom of a water
vessel such as a sump chamber, an ATO reservoir, a 5-gallon jug,
or in a barrel. The PMUP will fit through the bung hole of most
barrels & drums, and through the opening in many wide-mouth
water jugs.
POWER CONNECTION
Connect the PMUP power cable to either one of the DC24/ACC ports on an Energy Bar 832
or a 1LINK module.

The plug is keyed and will only fit in the DC24 port one way. The plug has a locking tab;
this tab must point in the same direction as the face of the EB832 or 1LINK module. Insert
the plug as shown:
To remove the plug from the DC24 port, press down on the back of the locking tab, then
pull it out.
CONTROLLING THE PMUP
The PMUP is controlled by the programming of the EB832 or 1LINK output to which it is
connected. The tiles for these outputs appear in APEX Fusion like this:

The above images show the default names of the DC24 “A” and “B” outputs. The middle
number indicates the AquaBus address of the EB832 or 1LINK, and will vary from system to
system.
The output must be programmed to operate the PMUP as necessary for your particular
application. Because the PMUP may be utilized in so many different ways, no programming
examples are provided herein. Refer to other Apex documentation for general
programming guidance.
