Summit Pump continues to grow and improve our services.


This year, Summit Pump expanded our engineering department adding more seats for mechanical designers and engineers.

With the new product lines, the demand for more mechanical designers and engineers was a must to keep up with production. The addition of office space assists our employees which increases organization and productivity, improving our customer’s experience.

The new space gives our quality control members the staging area needed to keep parts at a controlled temperature for accurate measurements with a clean and well organized area for measuring devices.

The new expansion supports our quality control professionals to keep to the high standards we put into our pumps and parts everyday!

Here you can access all of our brochures and manuals, review our most popular product lines, find your nearest distributor or email Summit Pump, Inc. directly.

There is a special link to Jim Elsey’s, General Manager to Summit Pump, Inc., published articles in each monthly edition of Pumps & Systems. Here you can educate your pump team and yourself with Elsey’s vast and interesting knowledge of the pump industry.

New with the website is something called “Pump Tips”. This is a news blog where you can find answers to most FAQs, collect information you may not have known about pumps, seals, hydraulics, motors and anything related to the above. We strive and take pride in educating our distributors and end users to ensure they operate at max efficiency as well as operating in a safe environment.

In Company News, you will be informed about what is happening here at Summit Pump, Inc. Most recently, our warehouse expansion to support the demand for the newly released SPPC (Summit Pump Progressive Cavity) products.

Enjoy the new resource, we look forward to providing you and your company the high end service and products you deserve!


Summit Pump, Inc. is proud to announce that we’ve expanded!

This new building adds 16,600 square feet to our existing facility. The expansion was designed to accommodate the growing demand for our new products and incorporates an in-house manufacturing area and increased warehousing space.



This expansion will allow us to take advantage of new product opportunities that will give our distribution network the competitive edge!




The Progressive Cavity Pump area occupies 2,975 square feet of the new building and includes 1,025 square feet of assembly space, a 2 ton cantilever crane, rotor and stator disassembler and a 3’x8’ work bench.






The SN manufacturing area occupies 1,628 square feet and includes an assembly area, hydro-static pressure test area, dual cantilevered cranes and two 3’x8’ work benches.





The remaining 11,639 square feet of space is dedicated to storing our rapidly growing inventory.





There have been numerous questions asking the differences of impellers and casings when there is an “H” or “G” following the pump size. For example:

  • 3×4-10 and 3×4-10H
  • 3×4-8 and  3×4-8G
  • 4×6-10, 4×6-10H and 4×6-10G
  • 8×10-15 and 8×10-15G

What do these letters indicate? The letters specifically by themselves don’t explain anything to you, except that the style is different.

Take the previous example of the 3×4-10 and the 3×4-10H. Casings have a 3 inch discharge port and both have a 4 inch suction port. The impellers are both 10 inches in diameter. Without getting into the “nitty-gritty” foil design equations, the difference is the impeller vane profile. Best shown visually below:

impeller_compair3x4-10Please note, the casings are also different between the 3×4-10 and 3×4-10H to fit these profiles. You cannot interchange a 3×4-10 impeller into a 3×4-10H casing and vice-versa.

As you can see some of the differences for each vane:

  • Entry angle of the fluid (angle of attack)
    • Also depends on RPM and volumetric flow rate
  • Camber (curvature)
  • Chord line (tip to tail line)
  • Leading and trailing edges
  • Max foil thickness
  • Surface geometries of the high and low pressure sides
  • Vane height or capacity of each vane

All these attributes affect the performance of the pump in just about all aspects: capacity, head, NPSHr, required horsepower and efficiency. The curves for the 3×4-10 and the 3×4-10H are shown below. Take notice of all the performance aspects and imagine how the impeller profile differences affect the performance. The most obvious being the vane height and the difference in the pump capacity.

There are differences in “H” and “G” versions of pumps and are very important to take notice of when ordering. Any further questions please feel free to contact your local distributor if you have any further questions regarding impeller style differences.
