PumpSim is an efficient software for modeling, designing, optimizing and simulating a fluid pumping network. This application is fully interactive and based on exactly the same 3D technologies used in Ventsim software . This software accurately enables the design and simulation of piping networks and pumping systems. The pump pressure can be modeled by the pressure of the pipes and the pressure applied to the pumping systems. It is also possible to model the volume and intensity of flow, the opening and closing of pipes and channels, the capacity of tankers and gutters, the density and viscosity of liquids, valves and spray nozzles, and so on. This program is able to estimate the costs and effectiveness of your network and make these two indicators better by offering suggestions.

PumpSim\’s graphical interface is advanced, dynamic and fully interactive and users feel comfortable working with it. The 3D engine used in this software is designed to allow for smooth rotation, zooming and moving of any part of the design. It is also possible to understand the performance of the network very well using instant animations. The design of the pumping network is not just about connecting the pipes together. It takes a little creativity to do this. You should also consider optimizing and saving it while doing the modeling work. One of the good features of the pump is its special attention to design optimization. It places you where you need it with alerts or suggestions so you can design the network with the maximum amount of optimization.

The program was previously run by Chasm Consulting, which was acquired by Howden Group after it was acquired.

Features and Features of Pumpsim Software:

  • Modeling all components of the fluid pumping network (pipes, ducts, pumps, tankers, manual and automatic valves, interfaces, drainage, etc.)
  • Calculates speed, pressure and other parameters
  • Animated simulation of fluid movement inside pipes
  • Calculate and estimate the level of optimality and the amount of final costs
  • Calculation of pressure on pumps and pipes
  • Analysis of tanker structure and capacity
  • Investigation of frictional effects of pipe wall
  • And …

required system  

Pumpsim ™ operates under Direct3D , a Microsoft standard introduced over 15 years ago. It is designed to run on Windows XP, Vista and Windows 7/8/10. Recent computers are likely to have a suitable graphics solution, however older computers (4 years or older) will require a Direct3D compatible graphics card (likely from ATI or NVIDIA). Suitable graphics cards are available for as little as $ 50.



Installation guide

Listed in the Readme file in the Crack folder.

Do not run the software after installation. Run Notepad in Run as admin mode, from the File -> open menu, go to C:\Windows\System32\drivers\etc and open the Hosts file (if you do not see the file, go to the bottom right corner Convert Text Documents to All Files) then two statements

Add to the end. Instead, you can completely block the software in the firewall. Then run the LicGen file from the crack folder and click on the PumpSim icon (right) to get a successful message. The software is now ready to use.

Note: The crack of this program does not work in newer versions of Windows 10 (probably 21H1 and later) and Windows 11!
