Epic Pump vs DP-4000
I have tested over 30 pumps in the past 5 years. The DP-4000 is the one the old forums still call the Cadillac. Here is exactly how the two differ, checked line by line against both makers’ own published specs.

- Does the job, with a catch
- Weak point
Two very different machines
Both are programmable and both show you a number. The difference is that one runs off your phone, and the other runs off a Windows PC and a wall socket.

What makes Epic Pro so superior
Every control on it exists to fix one of the four reasons men quit pumping: guesswork, effort, discomfort, and never running the same session twice.
- A motor with a brain. Press start and it builds, holds and releases to a number you chose.
- Water or air, same device. Water spreads the pressure evenly. Air is near-silent, with no cleanup.
- Press start and walk away. 10 auto-cycling modes ramp, hold, release and repeat on their own.
- You always know the number. Live pressure readout and a built-in timer, right on the head.
- It holds what you set. If the seal leaks, auto-hold puts the pressure straight back.

One of a kind
No other pump on the market has such features. Works with water + pressure readout + programmable via app!!

Epic set-up
The Pump + Cylinder setup is honestly one of the most well thought out systems I’ve used. From the start, you can tell it’s designed with intention and not just another generic pump. The digital display allows you to clearly track pressure in real time, and the control feels smooth and precise rather than jumpy or inconsistent, which makes a big difference during sessions.

As a person who hadn’t used pumps before this
As a person who hadn’t used pumps before this, I was amazed at just how large it made me on the first pump. The pump has easy instructions and the AI mode does all the work for you.
Where it actually matters
Six rounds. Same test for both pumps. Here is the card.
Epic Pump
5–1
DP-4000
Round 1What you pay to get going
Wins the round
A Starter Kit is $349 and the cylinder that fits you is already in it. One price, nothing else to buy.
Loses
$498 for the box, and their own page lists cylinders as a paid option at $54.95 each. You are past $550 before your first session.
Round 2What you need to run it
Wins the round
A phone. Build routines in the app, or press start and pick one of 10 modes on the device.
Loses
A Windows PC and a USB cable. Their spec sheet lists Windows XP through 11 and nothing else, so no Mac and nothing on a phone.
Round 3Power and where you can use it
Wins the round
Charges over USB-C and runs cordless. Desk, bed, hotel room, no socket involved.
Loses
A 12 volt wall adaptor. Even with a program saved to the device, their own copy says you still need a wall jack or a 12 volt supply.
Round 4Water sessions
Wins the round
Air or water from the same device. Water spreads the pressure evenly, and air lets you skip the shower entirely.
Loses
Air only. There is no water mode.
Round 5Packing it away
Wins the round
The head unscrews from the cylinder and the two pieces pack flat. No cables, no box.
Loses
A 5.25 inch case, a wall adaptor and a 10 foot connection line. It lives on a shelf, not in a drawer.
Round 6Depth of programming
Loses
10 smart modes ready to run, plus your own routines saved in the app. Enough for almost everyone, but it is not a programming environment.
Wins the round
Ten step points, upper and lower vacuum limit lines, unlimited program length, save to file and free lifetime software updates. If you want to tinker, they give you more to tinker with.
Final card 5 – 1Epic Pump takes the five that decide it
Results are permanent and real
Up to a full inch of girth is absolutely possible, and the verified buyers below got there. What they report is size that stayed, not the hour of swelling after a session. Erection quality is the change most men notice first, harder and fuller within weeks, and plenty add length on top of it.

Straight answers
Is Epic Pump better than the DP-4000?
For almost everyone, yes, and it costs less. Epic is one piece, runs cordless off a USB-C charge, works in water as well as air, has the cylinder in the box and is programmed from your phone. The DP-4000 is a benchtop box on a wall adaptor, air only, no cylinder included, and it is programmed from a Windows PC over a USB cable. Where the DP-4000 is genuinely ahead is depth of programming, and if you enjoy building routines step by step it is a serious tool.
How much does the DP-4000 actually cost?
Their own product page lists $498. That is the box, the software, a 12 volt wall adaptor, a 10 foot connection line, two quick connectors, a USB cable and a manual. There is no cylinder in it. Cylinders are listed as an option at $54.95 each, in five diameters, all 10 inches long. An Epic Pump Starter Kit is $349 with the cylinder that fits you already in the box. You will see $469 quoted on forums, but the maker says $498.
Does it need a computer?
To build or change a routine, yes. Their spec sheet lists Windows XP through Windows 11 and nothing else, so there is no Mac version and nothing on a phone. You can save a program to the device and run it without the PC connected, but you still need a wall socket or a 12 volt supply to run it at all.
Can I use either one in water?
Epic runs in water exactly the way a hydropump does, and switches to air when you would rather not get in the shower. The DP-4000 is a mains-powered air pump, so water is not an option.
How much pressure is safe?
Stay under 5 inHG of negative pressure, keep sessions to 15 to 20 minutes, and run 2 to 3 sessions a week. Release the pressure straight away if you feel pain, numbness or a colour change. Both devices show you a number, so there is no excuse for guessing on either. The DP-4000 goes to 13.5 inHg, which is far past anything you should be using.
Does a pump add girth permanently?
Pumping gives you a clear temporary size increase right after a session, and harder erections within a few weeks of consistent use. Permanent girth retention is modest and takes months of regular sessions. Anyone promising big permanent gains fast is selling you something.
What size cylinder do I need?
Diameter matters more than length. Too narrow bruises you, too wide swells the base and kills the seal. Epic cylinders come in 7 diameters from 1.5 to 2.87 inches and 2 lengths, and we size yours at checkout. The DP-4000 offers five diameters from 1.875 to 2.875 inches, all 10 inches long, and each is a separate $54.95 purchase.
What if it does not work for me?
Epic comes with a 180-day money back guarantee, and if the pump arrives damaged or develops a fault we replace it free. The DP-4000 carries a one year limited warranty, plus free lifetime updates to their software.
