Rotech makes drop-in pumps that fit what's already in the plant
Seven parts on who Rotech is, what each line replaces, the features you'll sell on, and how to work with them. Work through them in order: two quick checks at the end confirm you've got it. Your progress saves on this device.
A manufacturer, not a relabeler
- The pitch: Rotech calls itself the "Goldilocks" option. Legacy makers (Goulds, Flowserve, Sulzer, Xylem) have the engineering but can be slow. Typical aftermarket suppliers are fast but don't control their quality. Rotech designs and builds its own parts, so it can move fast without giving up quality.
- Not a copy: parts fit Goulds and Gorman-Rupp pumps, but Rotech engineered each one from scratch and tested the hydraulics. Performance comes from the vane angles, not from looking the same. That's the difference from the cheap replicas that gave aftermarket pumps a bad name.
- India plant: Rotech's Indian plant is about 8 miles from the Goulds (ITT) plant in India. They share vendors and engineers, and Rotech benchmarks itself against Goulds. The plant is ISO 9001 certified.
- Houston: moved to a new building in January 2026. It's becoming a training and test center, with hands-on distributor training planned for early 2027.
- Heavier, not cheaper-made: Rotech's castings weigh more than the industry average on average. Their lower cost comes from doing the work in-house, not from using less metal.
Case study: 25 pump ends in about 10 weeks
EOG Resources in Texas had cast iron MP pumps on produced water. They needed stainless, the OEM quoted 30 weeks, and the plant couldn't repipe. Rotech reverse-engineered the pump, cast it in stainless and shipped 25 pump ends that dropped into the existing piping, in roughly 10–12 weeks.
In the recording: company history from about 0:04, the EOG case study 2:59.
Goulds-interchangeable ANSI pumps, and a close-coupled version nobody else makes
ANSI B73.1 (from the 1970s) made every maker's process pumps share dimensions and footprint. Goulds and Flowserve (Durco) hold most of the installed base. Rotech's goal: when you sell a new ANSI pump into a plant, the plant's old spare parts don't become obsolete. Open each product. Green dots show the ones you've read.
Frame-mounted process pump1196: the Goulds 3196 equivalent
Low flow, high pressure1196LF
Flagship · Rotech exclusive1296: an ANSI pump close-coupled to a motor
Rotech's best seller, made since 2012. It uses the 1196's wetted parts on a JM motor, so it has the same hydraulics and fits the same ANSI piping. A 33-part bill of materials becomes six parts.
Close-coupled low flow1296LF
The low-flow radial-vane design, close-coupled. One of the few horizontal end-suction pumps that makes low flow at high pressure, so you aren't stuck with a vertical multistage. That matters on liquids that aren't clean water or glycol, such as wastewater.
Repairs · optionsShaft kits, high temperature, NACE and self-priming
- Shaft kits: a couple hundred pre-built kits on the shelf with SKF bearings (oil-lubricated; Inpro or other isolators on request). Interchangeable with Goulds, Griswold and Summit. Swapping a pre-built kit and tightening three bolts often costs less than tearing down and inspecting a power end, so plants stock them.
- High temperature: jacketed casings (steam jacket for liquids like asphalt that must stay hot), jacketed stuffing box covers and fin coolers.
- NACE MR0175 materials for H2S service, on request. Some materials comply by default; others need a special pour, so ask before the order.
- Self-priming ANSI: same power end with a self-priming casing.
- Split seals can be done, but there's little room on small ANSI pumps. Rotech doesn't recommend them there.
Lead times on exotic alloys
| Material | Typical lead time |
|---|---|
| Ductile iron, 316 stainless, duplex | Stocked |
| Hastelloy C | 16–20 weeks |
| Titanium | 24–28 weeks |
Rotech now quotes with a four-week buffer for foundry and shipping delays. Packaged pumps are laser-aligned at the factory, and the alignment report is saved to the work order: useful if a customer says a pump "can't be aligned." Rotech's standard base is bent channel milled flat, with polymer concrete and fabricated skids as upgrades. We usually build our own bases.
In the recording: ANSI history and Goulds interchangeability from about 4:51, power ends and NSF 61 7:50, alloy lead times 9:44, shaft kits and high temperature 10:40, standard features 13:23, the 1296 14:16, base plates and alignment 18:48, low flow and NACE 23:37.
Gorman-Rupp interchangeable, in both directions
| Rotech | Replaces | Use it for |
|---|---|---|
| SPT / SXT | Gorman-Rupp T and Super T | Solids handling: two-vane impeller passes 3″ spherical solids. Stocked 2″–12″. |
| SPU / SXU | Gorman-Rupp U and Super U | Higher-pressure boosting (five-vane impeller). Stocked 3″, 4″, 6″. Few competitors offer a Super U equivalent. |
| SCP / SFP | MP FlowMax-style pumps | Light-duty, economical self-primer: 1½″–3″, type 21 seal, up to about 25 ft suction lift. Good for recirculation and water/wastewater OEM skids, not harsh service. |
- Cutter plates are built in. Many lift stations want them: rags get cut up and passed, or cleared through the front cover.
- Trash can be cleared and the rotating assembly removed without disturbing the piping.
- Seals: TC/TC/Viton standard for abrasive liquid and sewage; custom seals for solvents like ketones, xylene and toluene.
- Interchangeable with Gorman-Rupp parts and rotating assemblies, and dimensionally with Pioneer and others. A spare rotating assembly on the shelf is often cheaper than rebuilding. Rotech also runs refurbishment programs: send back the old pump, keep the major castings.
- Coming: an upgrade from oil seals to bronze labyrinth seals to better protect the bearings, since oil seal failure is the usual reason these pumps die.
How to sell it against Gorman-Rupp
Other aftermarket competition: Pioneer (backed by Franklin Electric; strong in multistage and vacuum-assisted pumps), Summit and AllPrime. Rotech says it's at least even with them on delivery and better at packaging.
In the recording: trash pumps from about 24:39, replacing Gorman-Rupp at a treatment plant 27:27, other competitors 31:56, light-duty self-primers 34:03.
Split cases that drop into old footprints
The Pattern Rework Program (PRP)
Rotech split cases aren't parts-interchangeable with anyone. Instead, Rotech changes its pattern so the new pump drops into the old footprint: moved feet, new bolt holes, adjusted height. It runs a CAD stress analysis and thickens ribs where needed. It's a paid service, but usually far cheaper than repiping an old station, where civil work alone can run into six figures. Rotech says it finds a close enough fit about nine times out of ten. It started with Worthington LR pumps that Flowserve stopped making interchangeable, and has since done Goulds and others.
A win on lead time: at SSAB in Alabama, Rotech quoted 24 weeks against Goulds at 32 and Flowserve at 50, and won the split case job.
Other lines worth knowing
- RVI80 vertical inline (equivalent to B&G Series 80) and vertical multistage pumps.
- RoChem ISO 2858/5199 pumps: lighter and cheaper than ANSI but still with ANSI flanges. Up to 6,384 gpm, 450 ft and 662°F. Frame-mounted, close-coupled, or a hot oil version with a finned bearing frame. They share the casing and impeller across all three, so a plant can keep common spares.
- 1600 series: close-coupled, semi-open impeller, 56C motor, and a discharge that rotates in 90° steps. Built for OEM skids; sold as a pump, pump end or kit.
In the recording: vertical inline, ISO, hot oil and 1600 from about 35:07, split case and PRP 37:08, the SSAB win 40:57, retrofit flexibility 42:38, split case NSF 44:18.
