Industrial Pump Solutions: Travaini and SIHI Pumps from Prime Fluid

Written by Prime Fluid Management | 11 June 2025

Prime Fluid Management supplies a wide range of industrial pumps to meet the needs of New Zealand’s manufacturing, processing, and infrastructure sectors. Our range includes liquid ring vacuum, centrifugal, and multistage pumps from two globally recognised manufacturers: Travaini and SIHI.

This article outlines the most common pump types available from each brand, highlights key technical features, and explains how our local engineering support can help you select the right pump for your application.

Travaini: Modular Design and Modern Manufacturing

Founded in 1929, Pompe Travaini is a fourth-generation manufacturer producing over 16,000 pumps annually. Their factory is highly automated, with robotic machining, testing, and painting systems. Most components are made in-house, which contributes to consistent quality and shorter lead times.

Travaini’s product range includes:

Liquid ring vacuum pumps (single and multistage).
Centrifugal pumps (single and multistage).
Options for high-temperature fluids, chemical compatibility, and confined spaces.

Key design features include modular construction, standardised mechanical seals (DIN 24960), and availability in various materials including stainless steel and exotic alloys. Travaini pumps are also engineered with fewer components, which simplifies maintenance and improves mechanical reliability.

SIHI Pumps: Proven Installations and Familiar Configurations

SIHI is an historic brand in New Zealand and has been widely used. Known for their robust engineering, SIHI Pumps offer a broad range of liquid ring and centrifugal models. These pumps continue to serve reliably in many industrial environments, particularly where existing infrastructure is built around SIHI configurations.

While SIHI Pumps remain a viable option, some users are now exploring alternatives that offer greater flexibility, faster delivery, and more modular design options.
