Manufacturing, assembly and service under one roof.
Purpose-built on the west side of the Houston metro. Design, engineering, manufacturing, skid assembly and the alloy inventory all sit on this one site — which is why an emergency order here is a phone call rather than a supply chain.
Pinnacle-Flo, Inc.
Pinnacle-Flo, Inc. is a leading pump manufacturer headquartered in Houston, Texas, proudly serving customers across North America and beyond. Established in 2012, we’ve earned a reputation for durable, high-performance pumps tailored to demanding industrial environments.
What We Do
Based in Greater Houston, we design, engineer, and manufacture a comprehensive range of fluid-handling solutions:
- 8896 Series ANSI Centrifugal Pumps — precision-built for chemical, petrochemical, power, and process industries, capable of handling corrosive media with efficiency.
- 8830 Series ANSI Centrifugal Pumps — ANSI/ASME B73.1 in two frames, 100% interchangeable with Durco Mark III® Groups 1 & 2 for a straight rotating-element swap.
- Mad Dog Series Self-Priming Pumps — rugged and reliable for fast reprime operations in dewatering, transfer, and solids-laden media across multiple sectors.
- Blue Dog Series Air-Operated Diaphragm (AODD) Pumps — versatile, abrasion-resistant pumps ideal for slurry, shear-sensitive, and corrosive fluids.
- Buffalo Series Internal Gear Pumps — smooth, low-pulsation flow pumps, designed for precise handling of high-viscosity fluids.
- PFVA Series Dry Prime Pumps — solids-handling pumps that prime themselves from dry and keep running when the suction snores, for dewatering, bypass and sump duty.
We also offer complete pump skid packages, incorporating mechanical seal support systems and control panels, engineered for turnkey solutions.
Trusted in critical sectors.
- Petrochemical & Oil & Gas — meeting tight environmental standards and harsh conditions
- Water & Wastewater treatment — cost-efficient and reliable dewatering solutions
- Mining & Minerals — handling abrasive solids and demanding applications
- Power generation, agriculture, and food & beverage processing
How the line was built.
Pinnacle-Flo did not launch with five pump families. Each one was added because customers kept asking the same question and getting sent to a second supplier for the answer.
Founded in Houston
Pinnacle-Flo, Inc. is established in the Houston metro area to build durable, high-performance pumps for demanding industrial environments — starting with the market on its doorstep: chemical, petrochemical and oil and gas process service.
The 8896 and 8830 Series
Two ANSI process lines. The 8896 is a horizontal end-suction pump built to ANSI B73.1M across three power frames and thirty-one hydraulic sizes, to 6,000 GPM and 730 ft, in metallurgy from carbon steel through Hastelloy B and C. Standard dimensions so it drops into an existing baseplate; engineered seal chambers and extra metal in wear areas so it stays there.
The 8830 covers the same standard in two frames — the 8831 for Group 1 and the 8832 for Group 2 — across nineteen hydraulic sizes to 1,800 GPM and 780 ft, with reverse vane impellers, external impeller adjustment and Inpro bearing isolators. It is 100% interchangeable with Durco Mark III® Groups 1 and 2, so a changeout is a rotating-element swap rather than a re-pipe.
Blue Dog AODD
Air-operated double diaphragm pumps from ½″ to 3″ for the duty a centrifugal cannot do — running dry, emptying drums and sumps, moving shear-sensitive and aggressively corrosive fluids without a mechanical seal to fail.
Self-Priming SPP & SPPX & SPPUX
Heavy-duty solids-handling pumps to 7,150 GPM passing 3″ solids, designed to run high and dry above the water level. The SPPX adds external shimless wearplate adjustment — clearance restored by hand, without disturbing the drive or the seal.
PFVA Series Dry Prime Pumps
Solids-handling pumps in 4″, 6″ and 8″ to 4,850 GPM and 164 ft, passing spherical solids to 3.9″. A belt-driven air compressor primes the pump from dry and holds prime through a snoring suction, and the seal runs dry without damage — for dewatering, bypass and sump duty where the liquid level is not guaranteed.
Buffalo Internal Gear
Smooth, low-pulsation flow for fluids up to 2,000,000 SSU across a temperature range from −120°F to +800°F — the positive-displacement end of the line, for the fluids a centrifugal simply cannot move.
Skid Packages & Growth
Complete pump skid packages incorporating mechanical seal support systems and control panels, engineered for turnkey installation — and a continuing investment in new technologies and skilled personnel as the business diversifies into today’s world market.
