Fybroc Pumps

Fybroc is an advanced technology pump manufacturer specializing in fiberglass-reinforced composite centrifugal pumps, designed to handle corrosive and other difficult liquids.

Their history dates back to 1966 when the first fiberglass-reinforced composite pumps were pioneered by the Sethco Manufacturing Company. At that time, Sethco had begun a small operation dedicated to composite pumps to provide larger flow rates than were currently available with thermoplastic materials.

Met-Pro Corporation, Fybroc’s parent company, acquired Sethco in 1970. The composite pump operation was moved to Hatfield, Pennsylvania in 1971 and named Sethco Pump Company. In early 1975 Sethco Pump Company was renamed Fybroc Division.

Rapid sales growth nearly outstripped their production capacity, so in September of 1991 Fybroc moved into a brand new, 48,000 square foot, state-of-the-art production facility in Telford, Pennsylvania.
Fybroc’s Telford facility, which is solely dedicated to the manufacture of fiberglass-reinforced thermoset vinyl ester and epoxy resin pumps, has recently completed construction that doubled its size to just under 100,000 square feet.

Today, aggressive new product development programs, along with continued improvements in molding techniques, have made Fybroc a  world-leader in the manufacturing of fiberglass-reinforced thermoset vinyl ester and epoxy resin pumps.

Fiberglass Reinforced Pumps are the only thing Fybroc manufactures. As the first company to develop a fiberglass reinforced pump in 1966, Fybroc has continued to focus on non-metallic pumps for the past 30 years.

Advanced Composite Pump Designs
The fiberglass components in Fybroc pumps are produced using a Resin Transfer Molding (RTM) process. The major advantage of this process is that it allows for the controlled placement of long strand fiberglass reinforcement in high stress areas providing components with excellent physical properties, allowing the design of thinner-walled structures, and in turn permitting the use of nearly pure resin systems for optimum corrosion resistance.

Ordinary compression molding methods, however, utilize chopped glass random reinforcement that provides comparatively lower strength characteristics. In addition, the inherent physical properties of this technique and the exothermic properties of the highest quality resins force the inclusion of large amounts of clay filler in the bulk molding compound. These fillers detract from the corrosion resistance of the base resin and certainly add no strength.

While the compression molding approach sacrifices both corrosion resistance and strength, the RTM method optimizes both.

Fybroc’s Flange is as Strong as Metal
Critical components such as the single-piece casing, and its heavily gusseted suction and discharge flanges, benefit from the reinforcing properties of the RTM process. This permits the handling of normal pipe loads under full working pressures. This method of reinforcement in the casing extends the life of the component and provides unparalleled strength without degradation in corrosive environments.

Dual Volute Casing for Maximum Seal and Bearing Life
Fybroc’s larger pump sizes, with potentially high radial loads, feature a dual volute casing to dramatically reduce radial loading and increase the life and serviceability of bearings and mechanical seals.

Integral Shaft Sleeve Eliminates Shaft Damage
Their horizontal pumps feature an integral shaft sleeve that eliminates potential “O” ring seal and shaft damage.

Extensive Interchangeability Simplifies Spare Parts Stocking Requirements
With Fybroc pumps, using one material to cover a wide range of chemical applications allows extensive interchangeability and simplified parts stocking requirements as compared to pumps constructed of specialized metals. In addition, our pumps are designed with a high degree of interchangeable parts such as bearing frames, covers, casings and impellers.

High Purity Vinyl Ester Resins
Fybroc pumps feature high quality and high purity vinyl ester resins with the lowest percentages of inert fillers. We offer a complete range of vinyl ester/epoxy resins to meet a broad range of corrosion resistant applications. Our capabilities include pumps with synthetic veil for resistance to hydrofluoric acid, materials to handle moderate or heavy abrasives, special catalyst systems for handling strong bleaches such as sodium hypochlorite, special resin systems to meet FDA specifications, and second generation epoxy resins for certain acid and solvent combinations.

Thermoset vs Thermoplastic
Fybroc’s vinyl ester resins are high quality catalyzed thermoset resins that provide higher temperature capabilities and strength than conventional thermoplastic resins. Catalyzed polyester resins provide higher strength than non-catalyzed resins due to the cross-linking of molecule chains.

Fybroc Manufactures All Their Own Fiberglass Components
By manufacturing their own fiberglass components, Fybroc can control the catalysts and other additives to insure the highest strength and corrosion resistance.

The Highest Glass Loading Ratios
Having complete control over the entire manufacturing process allows Fybroc to provide the highest glass loading ratios.

The Shortest Lead Times in the Industry
Due to Fybroc’s reduced dependence on outside sources, Fybroc boasts the best overall lead times in the industry.

Fybroc performs hydro testing on all individual components as well as all finished horizontal pumps including installed mechanical seals.

Fybroc has the flexibility to meet special customer requirements for pump designs, special mechanical seals and unique installation problems.
