Delavan designs, engineers and manufactures a wide range of roller pumps to meet the widest ranges of low-volume, moderate-pressure pumping applications. To ensure the best performance for your investment, we incorporate such features as “Ultra” rollers, heavy-duty sealed bearings, Viton seal rings, stainless steel shafts and rotors, and close tolerance machining.  All are standard.

Our Stainless Steel Diamond Series™ 8900 roller pump is a great example of why Delavan innovation tops the roller pump category. Stronger than steel, it’s simply the best chemical-resistant roller pump you can buy. “Roundup Ready,” a Delavan Stainless Steel Diamond Series roller pump lasts ten times longer than a cast iron pump.

Plus, Delavan roller pumps are field serviceable—saving precious time and money when you need to replace the rollers.
