IMO ACE 038K4 Rotor Set G054M Kit | Genuine IMO Pump Spares
- Brand: IMO AB
- Model Details: ACE 038K4 Rotating Group
- MPN: G054M (Rotor Set)
- Product Category: Marine & Industrial Pump Spares
The G054M Rotor Set is a rotating assembly that has been precisely manufactured for the ACE 038K4 pump generation. Over time, temperature cycling and particles getting stuck in the screw profiles can cause internal slide and lower discharge pressure. This kit has everything you need to fix the pumping element, so you can be sure that your fluid transfer systems will work at their best with as little vibration as possible.
The IMO ACE 038K4 Rotor Set (G054M Kit) is the main part of your ACE series triple-screw pump. This assembly is made to keep the exact tolerances needed for safely handling high-pressure fuel and lubrication oil, as well as to bring back factory-spec volumetric efficiency as a real replacement rotating group.


Main Features
- The IMOs unique geometric screw design sets precision profile grinding apart. The goal of this design is to lower internal turbulence and increase vacuum lift.
- Increased Durability: Made from high-quality alloy steel that has been treated to resist the harmful effects of heavy fuel oils (HFO) and low-sulfur fuels (LSMGO).
- Hydraulic Balance: The rotor set is made to keep the pumps axial balance, which lowers the stress on the thrust bearings and raises the pumps Mean Time Between Failures (MTBF).
- The K4 model was made to fit right in, so there wont be any problems with clearance while putting the pump casing together.
- Efficiency Recovery: Stops the motor from making up for leaks inside by lowering energy use and bringing the flow rate back to
Uses:
- Marine Propulsion
- Purification Systems
- Industrial Oil Transfer Systems
- Power Generation Company
Installation Tips From Our Engineer:
- Check the Casing Bore: Before putting in the new G054M rotor set, use a bore gauge to measure the inside of the pump housing. Even with a fresh rotor set, a worn case will still lose efficiency.
- Before lubrication is important: After replacing the rotor, never start a pump without water. To stop galling from happening when the pump first starts up, manually prime it with the right system fluid (lube or fuel oil).
- Check the Mechanical Seal: When you open the pump to install the G054M kit, you should also change the mechanical seal (G057). A new rotor set can raise the pressure within, which could make an old, weak seal break.
- Check the alignment: After installing the motor-to-pump connection, use a dial indicator to make sure it is aligned correctly. Your new idler rotors will wear down unevenly if they are even a little out of alignment.
