Celeros Flow Technology: Plenty TRIRO Pumps Deliver Optimum Lube Oil and Seal Oil Performance

08.01.2025
The Plenty TRIRO rotary triple screw pump from Celeros Flow Technology is primarily designed for handling clean lubricating liquids. It ensures consistent flow and prevents the liquid becoming emulsified, making the Plenty TRIRO the pump of choice for forced lubrication and seal oil circulation applications.

The Plenty TRIRO is the preferred pump for API 614 oil systems and can be used on a wide variety of compressor, turbine, gearbox, pump seal oil, and sealing system circulation systems. 8Image source: Celeros Flow Technology)

The axial pulse-free pumping action used by the Plenty TRIRO means there are no pulsing hydraulic shock characteristics. The action, which is similar to that of a piston moving constantly in one direction, returns a very low shear characteristic, all of which means that the lubricating fluid being pumped does not degrade during transfer.

The Plenty TRIRO also has a low cost of ownership as it has only three moving parts: a power rotor and two idler rotors. This elegant and simple design makes the pump highly reliable and simplifies maintenance requirements.

The high-speed operation and compact design of the TRIRO pump results in a low cost, space saving unit that is suited to a wide range of applications, including as a main oil pump (directly driven from the main machine), AC auxiliary oil pump, DC run down or DC emergency pump, and control oil pump. The Plenty TRIRO is the preferred pump for API 614 oil systems and can be used on a wide variety of compressor, turbine, gearbox, pump seal oil, and sealing system circulation systems. The pumps can be supplied to API 676 standards, or to individual customer project requirements.

The Plenty TRIRO can handle flow rates of 0.1 to 300m³/hr and fluids with viscosities ranging from 2 to 1750 cSt as standard. Custom designs to accommodate higher flow rates and viscosities can be considered. This highly reliable pump will also withstand operating pressures up to 137 bar and operating temperatures of -20◦ to 150◦ C.

The versatile Plenty TRIRO pumps are available in 17 frame sizes with various pitch angles and length and can be specified in many different material combinations. For maximum flexibility, the pump can be pedestal mounted, foot mounted, vertical free standing, sited on the tank top or submerged. All TRIRO pumps are designed to operate at either electric motor synchronous speeds or from direct coupling to a power take-off from the main machinery.

Standard TRIRO designs are available to suit API applications, though most customer and industry standards can be accommodated.

How to Manage Heat in Vacuum Systems?

31.08.2026 -

Every vacuum pump converts electrical energy into mechanical work. Inevitably, much of that energy becomes heat, resulting from heating in motor windings, friction between moving parts, and gas compression. While heat generation is unavoidable, how it is managed influences not only the efficiency of the vacuum pump, but can also affect the efficiency of other associated systems and equipment located nearby.

DESMI: The Engineering Behind Reliable Marine Boiler Systems

22.07.2026 -

In marine boiler systems, performance is never defined by a single component. It is the result of how well every element works together under pressure – literally. DESMI has spent decades refining one critical part of that equation: how water flows through high-temperature, high-pressure boiler systems. Not just supplying pumps, but continuously improving how they perform in real operating conditions. Because in this application, efficiency is not enough. Reliability is everything.
