Stenner Pumps Company

What Stenner Pumps Company does

Stenner Pump Company is a privately held, veteran-owned US manufacturer of peristaltic metering pumps, founded in 1957 by G.H. Stenner in Jacksonville, Florida. The company designs, builds, and ships peristaltic pumps that move fluid through a flexible tube compressed by rollers, a design that prevents pumped fluids from contacting mechanical moving parts, eliminates the need for check valves or foot valves, supports self-priming up to 25 feet of vertical lift, and allows dry running without damage. Its portfolio spans the Classic Series (electromechanical pumps with the proprietary QuickPro tool-free pump head), the S Series smart pumps with NEMA 4X enclosures, brushless DC motors, 4-20mA and Modbus RTU over RS-485 process-control integration, leak detection, and backup-pump transfer, and the Econ Series of economical pumps for light-duty, timer-activated, flow-activated, 1:128 medicator, oral-vaccine, and variable- or fixed-speed applications. Complementing the core pumps are pre-assembled tank systems (7.5, 15, and 30 gallon), meter systems (FP, Integrator, Stennicator, Proportional Injection), accessories (pulse cycle modules, flow switches, water meters), and a recurring replacement-parts business across multiple tube chemistries.

The company's go-to-market is exclusively indirect: Stenner sells through established wholesale distributors, OEM channel partners, and catalog companies under an open distribution policy that places no restrictions on reselling, pricing, or geography. Pricing is not publicly disclosed; inquiries are routed through phone, email, and technical support channels ([email protected], [email protected], [email protected]) operating 7am-8pm ET on weekdays. Stenner maintains four US facilities — Jacksonville, FL (headquarters and primary manufacturing), Birdsboro, PA (distribution), New Century, KS (distribution), and Las Vegas, NV (regional training and repairs) — to compress lead times to channel partners, with a stated 3-day lead time on products. The company carries sector-specific certifications including NSF/ANSI 61 & 372 (drinking water components), NSF/ANSI 50 (pool equipment), CE IP65, and cULus, which support sales into regulated municipal, pool, and industrial verticals.

Stenner serves a diversified set of end markets across water conditioning (drinking water), animal health (poultry and swine medication, oral vaccines), pool and spa, industrial process water treatment, and municipal/industrial wastewater, with secondary exposure to cooling tower, irrigation, car wash, food and beverage, and metal finishing. The S Variable Series launched in 2024 expanded the smart-pump range with variable speed, leak detection, and remote start/stop, while ongoing trade-show presence (Florida Rural Water Association, AWT, WEFTEC, and others) and dedicated international sales support signal continued channel investment. With no public revenue, no disclosed funding, no acquisitions, and a stable workforce (31% of employees with over ten years of tenure), Stenner operates as a mature, family-controlled specialty industrial manufacturer focused on incremental product refresh and distribution depth rather than scale-stage expansion.

Core offering

Stenner manufactures peristaltic metering pumps for precise chemical injection and fluid handling across applications including water treatment, pool and spa, animal health, industrial process, wastewater, food and beverage, and metal finishing. The company produces multiple pump series (Classic, S Series, S420, S10P, S128, S Variable, Econ) along with tank systems, meter systems, accessories, and replacement parts. Stenner sells exclusively through wholesale distributors, OEMs, and catalog companies, with no direct retail channel.

Product overview

Stenner Pump Company manufactures peristaltic metering pumps as its core product offering, along with complementary tank systems, meter systems, accessories, and replacement parts. The product portfolio includes three main pump series: the Classic Series (electromechanical peristaltic pumps with QuickPro head technology), the S Series smart pumps (with digital interfaces, 4-20mA control, and NEMA 4X enclosures), and the Econ Series (economical pumps for light-duty applications). Within these series, specific models address different needs: S420 for 4-20mA process control integration, S10P and Econ FP for flow-activated dosing, S128 and Econ Stennicator for 1:128 medicator applications, Econ Vaccinator for slow-delivery oral vaccines, Econ LD for low-volume precision dosing, and Econ VX/FX for variable/fixed speed general use. Tank Systems (7.5/15/30 gallon) and Meter Systems (pre-assembled pump with water meter) provide complete installation solutions, while Parts and Accessories support ongoing maintenance and customization.
