FRP Pumps

ISO logo

ISO 9001:2015 Certified

Magnatex/Argal MFRP ANSI Mechanical Seal Pumps are designed to handle the most demanding corrosive services in chemical process facilities, aquaculture facilities, aquariums, steel plants, pulp and paper plants, electric utility plants, industrial and municipal wastewater treatment plants. All wet end parts are manufactured from high strength fiberglass reinforced polyester (FRP) in order to resist corrosion, abrasion and operating temperatures between -50°F (-45°C) and 250°F (120°C). The pumps are manufactured to conform to ANSI B73.1 dimensional requirements and are available in both close coupled and long coupled configurations, depending upon your preference.

Fiberglass Reinforced Plastic Pumps

Manufacturing Process

The pumps are manufactured using the RTM injection molding process. Reinforcing layers of fiberglass mat are placed in molds prior to injecting the appropriate resin, depending on the application. The use of layers of different weight mats produces a finished product of the highest possible mechanical strength, comparable to stainless steel or alloy pumps, so that a casing armor is not required to reinforce the strength of the pump. Thermoset resin pumps offer higher strength, thermal and dimensional stability and much longer life than competitive thermoplastic pumps.


Depending on the application, the use of different formulations of epoxy vinyl ester resins provides a broad spectrum of chemical and abrasion resistance, such that the pumps are commonly used in industrial and municipal waste water treatment facilities, water parks, large scale aquariums, zoos and aquaculture farms.
