AS Series - Hygienic liquid ring pump
Complete range of hygienic liquid ring pumps for the food and pharmaceutical industries. Seven modular sizes provide high flexibility and low spare part costs. Close coupled design with extra supported shaft and standard IEC motor.
The AS series has the ability to maintain a vacuum under varying suction conditions making them ideal for applications where the incoming liquid contains gas or air and handling foaming liquids or where only the suction pipe is partially filled.
Before the first start-up, they must be initially filled with liquid. After that, liquid remains in the pump, which allows for quick self-priming, even if the suction line is emptied.
The construction and quick disassembly design make the AS series particularly suitable for a wide range of applications such as CIP returns etc.

TBA series - Multistage/side channel centrifugal pump
Pompetravaini TBA series self-priming liquid ring pumps use the side channel principle. The open star wheel is hydraulically balanced and enclosed between the suction and discharge port plates to form the pumping stage. The discharge stages are mounted in series to provide proportionally higher discharge pressure with smooth flow. For handling hazardous, toxic, odorous or polluting liquids and other applications where zero liquid leakage is desired, the TBK and TBAK magnetic drive pumps are available, based on the TBA and TBH series. TBA pumps have extremely low NPSHr requirements and are particularly suitable for handling liquids near the vapor formation pressure of the liquid, volatile liquids and other difficult applications. The design is especially suitable for handling liquids with mixed gases and liquefied gases such as LPG. The TBA series has the performance, design and operating point characteristics of the TBH series. The pump components are interchangeable, reducing the need for spare parts for both series. The TBA series pumps are suitable for handling clean, hot or cold, liquids, corrosive, in chemical, petrochemical, pharmaceutical, food industry etc. Applications; Removal of condensate and distilled liquid, solvents and liquefied gases, boiler feed water, handling of liquids from processes under vacuum, fire fighting systems and autoclaves, marine drinking and sanitation systems, high pressure flushing. -
