PumpBase 3  - New!      

Pump Selection and Catalog Production Software
for Windows XP/Vista/7/8
PumpBase Plot

PumpBase 3 now includes many new features such as Graphical Curve Entry, detailed Multi-Stage Analysis and Catalog Building. PumpBase is still as fast and efficient as it's been for its 20 years of use, but now its more powerful than ever. Download the User version and try it for yourself!

What PumpBase Is...
PumpBase is a sophisticated software application that finds the best pumps for your liquid conveyance design whether its a water distribution system or a chemical delivery system. You define the pumped liquid, operating parameters and specify up to 40 additional selection criteria. PumpBase includes many Catalogs that contain thousands of curves from dozens of participating pump manufacturers and can import any future updated Catalogs. Detailed reports are produced that can be sent to pump manufacturers and sales reps for further application verification and price quotes.

New Features...

Curve Entry via ImageGraphical Curve Entry - This latest version introduces the ability to enter pump trims from jpg, bmp or gif images. It is a much faster process of entering curves (and users say it's even fun!) Any Pump performance curves can be grabbed from web pages, and once calibrated, you simply click your mouse on the important points of the pump curves to enter them. Your curves are plotted directly on the image using PumpBase's mathematics which assures you the data is being captured correctly.

Multi-Stage Analysis - Detailed analysis of the exact required trim sizes for each individual trim size is provided in this latest version. The algorithm is very fast and accurate and saves engineers a lot of time when determining optimal trim sizes for machining.

Two Way Communication with HYDROFLO
- With one click HYDROFLO passes a pump's calculated operating flow and head to PumpBase for pump selection. Add any additional selection criteria to your search and obtain all the pumps that will do the job. With another click PumpBase passes back a selected pump's curve to HYDROFLO for use in your design.

Catalog Production - Pump Manufacturers can now build complete Catalogs of their pump lines using the Catalog Builder version and combine them into a single file for distribution. Users can easily load the files and pick and choose which Catalogs they want to install. PumpBase even shows them which Catalogs they already have and which are updates to their existing Catalogs and gives proper installation instructions. Pump Catalogs can be distributed by the manufacturer or placed on the web for User access.

PumpBase 3 Versions...

Catalog Builder version can do everything from pump selection to build pump Catalogs. This version is for companies that want to create full Catalogs of pump lines and distribute them to end-users, customers, sales reps and distributors so that they can chose from those pumps when doing highly productive and accurate pump selection on their PC. Pump Manufacturers can build and test Catalogs of their pump lines.

User version can load Catalogs, get fluid system operating results from HYDROFLO and perform pump selection on those results. View and select from Pump Catalogs. Enter and edit your own Pumps.

The Academic version has all the pump selection and editing functionality of the other versions but cannot load additional Catalogs (it uses the included Catalogs and it cannot create Catalogs - but hey, it's free to use!)

Main ScreenPump Selection Process

View all pumps by default (no criteria setting) - this allows simple browsing and viewing of all pump performance curves (adjusted for any viscosity effects). As you specify requirements, the selected installed Catalogs are filtered for those criteria. Specify TDH (Total Dynamic Head) and Design Flow, NPSHA (Net Positive Suction Head Available), Static Head and System Curve shape to select pumps whose operating envelopes include the your design point and operating parameters.

NPSHA (Net Positive Suction Head Available) should be above a Pump's NPSH required for proper operation and cavitation prevention. Specify exact liquid properties to have pump performance curves automatically corrected for viscosity effects. Additional manual correction factors can be specified to account for performance changes when stocks, slurries and other viscous liquid flow is being modeled.

Additional selection criteria such as Catalog, Pump Key, Series, Speed, Cycles, Max Sphere Size, pump features, orientation and application type are available.

Select Pump Results

Results of PumpBase's selection process will list all pumps suitable for your detailed application ranked by efficiency along with stages needed, NPSHR and other operating parameters. Full plots of pump performance, system and NPSHR curves are provided. Detailed specification reports can be sent to manufacturer or sales reps for confirmation of proper application and price quotes.

Selected pumps can be filtered by Pump Key text. Pumps can be emailed to other users for their use and analysis. Online information for pumps is available with a single click. Pump Manufacturer information is available along with single click email and website links.

For Multi-Stage Pumps, the number of impeller stages needed to provide the TDH and the calculated NPSHR are displayed, but more importantly, detailed individual impeller trim sizes, power and efficiency are provided. Viscosity correction factors and liquid temperature changes are displayed on individual pump performance curve plots.

Pump performance curve plots display the actual operating point (which may be different than the design point depending on cut increments). NPSHR plots along with calculations of Brake horsepower, Specific Speeds at the actual operating point for a given impeller trim or speed are displayed. Maximum power for the operating curve and maximum power for pump is offered.
