Neptune Systems PMUP v2 Practical Multipurpose Utility Pump


Item #: NS1195

Ships Free!

In Stock

The PMUP (Practical Multi-purpose Utility Pump) is a 24VDC submersible pump that has multiple uses for your aquarium needs, including:

  • Auto Top-Off (ATO)
  • Carbon Reactors
  • GFO Reactors
  • Biobellet Reactors
  • and many other marine or freshwater needs

What`s new with the Version 2 PMUP you ask?

  1. It comes equipped with an automatic shut off when dry
  2. Features an over-temperature protection
  3. Stands upright on a newly designed removable slotted screen
  4. Easier to clean and maintain

Connecting your PMUP

The PUMP still connects to the DC24 accessory ports on either the 1Link ModuleEnergy Bar 832, WAV powerheads, or, the new Apex.  These ports are switchable and can power the pump on or off just as any other outlet on the Energy Bar.


One of the more popular uses the previous PMUP was known for, it still holds true for Version 2

With enough power to push water upward to 14 feet - that`s a whole floor up! This means you could store your RO in your basement, downstairs in a utility room and still have enough juice to top your tank off.

With its vertical design, bottom intake and top oriented output the PMUP will fit nicely into jugs or other RO containers by simply dropping it in.

Reactor Use

Now you can run GFO, carbon, or biopellet reactors safely and while using less than 20 Watts of power, which in turn reduces heat exchanged into the aquarium.

Removable Screen

Clean and maintain your pump has never been easier.  Many other ATO pumps are not designed to be maintained, so once they become unsalvageable or inoperable, they are disposed of.  The PMUP, however, has in easily removable screen cover that not only keeps unwanted objects out, but also makes it easy to clean and service the pump.


The PMUP`s output easily connects to standard tubing or fittings.  It has a smooth 3/8" (9.5mm) output a silicon tube can slip right over, or, a standard push-fit connector to accommodate hard-line tubing.


  • Dimensions - 4.58" x 2.24"
  • Flow rated - 100gph @ 0`
  • Outlet size - 3/8" (9.5mm)
  • Max Head -14`
  • Power consumption - 17 watts

Use Requirements:

  •  APEX Control System (any model)
  • 1Link Module or Energy Bar 832 with available DC24 accessory port

Works as expected

Works great for ATO. I had been using a fixed peristaltic pump for years for ATO but that finally failed. I have only been using for couple of weeks.

Decent ATO Pump

Cons: High price for what it does, loud

These pumps were designed to only ‘work’ with other Neptune products. Upon install, it is noticeable louder than the previous model. Previous model ran dry after ATK malfunctioned and pumped between 3-5g of fresh water into my system. Hopefully this wouldn’t happen again as I believe these pumps automatically shuts off (and I think the new optical sensors are better sealed)
