AS Series - Hygienic liquid ring pump
The AS Series is a hygienic, self-priming liquid transfer pump for the food and pharmaceutical industries. The pump is designed for hygienic applications where the incoming liquid may contain gas or air, where foaming liquids need to be handled, or where the suction tube is only partially filled.
The liquid ring principle allows the pump to maintain a vacuum under varying suction conditions. After the initial filling with liquid, some liquid remains in the pump, which ensures rapid self-priming even when the suction line is empty.
- Hygienic self-priming liquid ring pump for the food and pharmaceutical industries.
- Seven modular sizes provide high flexibility and low spare parts costs.
- Short-coupled design with an extra-long shaft and an IEC-standard motor.
- Maintains a vacuum under varying suction conditions.
- Suitable for media containing gas or air and foaming liquids.
- Can be used even when the straw is only partially filled.
- Quick self-priming function after the first fill with liquid.
- Quick disassembly for easy servicing, inspection, and cleaning.
- Suitable for CIP returns and other hygienic applications.
- Capacity: flow rates up to 55 m³/h and head up to 45 m.
- Temperature range: -20 °C – +100 °C.
- Materials: Wetted parts in CF-3M 1.4404 / AISI 316L acid-proof stainless steel and electropolished.
- Elastomer (FDA Regulation (EC) No 1935/2004): NBR, EPDM, Silicone, Special fluorocarbon seal (FPM - FKM), FEP, FFPM - FFKM.
- Connections: DIN, SMS, IDF, BS/RJT, DS, clamp, and flange in accordance with EN 1092-1 PN 16.

TBA series - Multistage/side channel centrifugal pump
The TBA series is a self-priming liquid ring pump from Pompetravaini that utilizes the side-channel principle. The open impeller is hydraulically balanced and enclosed between the suction and discharge port plates to form the pumping stage. The pressure stages are series-mounted to provide proportionally higher discharge pressure with uniform flow. For handling hazardous, toxic, malodorous, or polluting liquids, as well as other applications where zero liquid leakage is desired, the TBK and TBAK magnetically driven pumps are available, based on the TBA and TBH series. -
TBH series - Multistage centrifugal pump
The TBH series is a self-priming liquid ring pump from Pompetravaini with extremely low NPSHr requirements. The series is particularly well-suited for liquids near vapor pressure, volatile liquids, and other demanding applications. The pump is designed to handle liquids containing gases as well as liquefied gases such as LPG. The TBH series is used for clean, hot, cold, or corrosive liquids in the chemical, petrochemical, pharmaceutical, and food industries. -
