Roto-Jet® centrifugal pumps (TRILLIUM PUMPS – ROTO JET)
Description

Roto-Jet®, integrated within Trillium Flow Technologies, is a brand specialising in Pitot tube technology for high pressure, low flow pumping. Its international recognition is based on a clearly differentiated offering, oriented towards applications where pressure, operational stability and process reliability are more relevant than flow rate. This specialisation allows it to occupy a very well-defined niche within the industrial centrifugal pump market.

Pitot tube technology offers stable operation even away from the region close to the BEP, which is a clear advantage over other solutions for high pressure–low flow services. This feature is highly valued in recirculation, system feed, injection and other services where the process does not always operate at a fixed duty point. In these applications, the correct selection of hydraulics, materials, sealing and overall pump configuration is key to adapting the equipment to the fluid, temperature, pressure and service demands.

The design combines a favourable hydraulic performance with robust mechanical construction, which helps to reduce interventions, improve predictability and extend the operating window compared to other centrifugal alternatives. This makes Roto-Jet a particularly attractive option for processes that prioritise pressure, stability and continuous duty. The appropriate selection of the Pitot system, hydraulics and structural arrangement directly influences flow stability, tolerance to process variations and equipment service life. The range includes both overhung designs for general service and API 610-compliant solutions, with between bearings construction for more critical services.

These pumps are best suited for energy, refining, petrochemical, chemical and other industrial processes requiring high pressures, relatively low flow rates and continuous operation. Roto-Jet’s proprietary technology addresses this niche with a clearly specialist solution strongly oriented towards process reliability.

Other Features

The Roto-Jet RO-FT is a Pitot tube pump specifically designed for low flow, high pressure services — a particularly robust solution for demanding process applications in refining, petrochemical and chemical industries. Its operating principle combines a rotor that imparts energy to the fluid and a stationary Pitot tube that converts that velocity into static pressure, achieving high differential heads in a single stage at relatively low speeds compared to other available solutions.

In addition, the RO-FT is aligned with API 610 and incorporates features for critical service environments, including between bearings configuration, API 682 cartridge seals, low required NPSH and the absence of wear rings, reinforcing its suitability for low flow–high head services requiring high reliability and lower life-cycle cost.
