The new AS Series combines the benefits of TONKAFLO, the industry-leading pump, with the durability of all stainless steel construction. The AS Series is a multi-stage, centrifugal pump with an all stainless steel liquid end mounted on a high thrust bearing frame. Engineered to be efficiently driven by a standard motor, each of the AS Series pumps offers dependable performance and long life. And with over 200 standard models, there is an AS Series pump to fit almost any 50 Hz or 60 Hz application.
Especially designed to meet tough industrial demands, AS Series pumps tolerate the most punishing applications and harshest environments. Ideal for membrane system applications, AS Series pumps also excel in industrial boost applications such as water soluble machine coolants, sanitizing systems and higher temperature water recirculation.
Features and Benefits
All Stainless Steel Construction makes AS Series pumps more durable and less susceptible to operator error. AS Series pumps are also chemically compatible with hydrocarbons, and can perform within a greater temperature range than the standard TONKAFLO SS Series.
Fabricated Sheet Metal Stages require less maintenance, and eliminate the need to balance pump impellers. The end result is smoother operation, less vibration and longer pump life.
Separate Bearing Frame increases pump reliability and life because there is no thrust load on the motor. In addition, this feature allows AS Series pumps to be powered by standard motors.
Modular Liquid End allows service of the mechanical seal without disassembling the liquid end of the pump. The AS Series’ modular design also facilitates service of both pump and bearing frame, and permits design flexibility when positioning piping.
Industry Standard Mechanical Seal on pump inlet delivers higher boost pressure capacity and longer seal life, and simplifies the specifying and finding of replacement parts.
Victaulic Connections reduce piping stress and make the installation of AS Series pumps easier.
