Safag Danfoss 576 NVBGRMDC-3 Industrial Oil Pump

Safag Danfoss 576 NVBGRMDC-3 Oil Pump

The Safag Danfoss 576 NVBGRMDC-3 Oil Pump is a heavy-duty, high-precision internal gear pump designed for heavy industrial and maritime fluid transfer applications. Built by Safag to Danfoss specifications, this machine is suitable for self-lubricating non-aggressive fluids such as heating oils, heavy fuel oils and industrial lubricants. The NVBGRMDC-3 type features a pressure stage of 6 to 25 bar, Clockwise (DC) rotating design, integrated pressure regulating valve and standard return connection. They are commonly employed on maritime auxiliary engine fuel systems, industrial burner skids and lubrication circuits demanding continuous, pulsation-free delivery under strong thermal and mechanical demands.

Key Features

1. Engineered with an internal gear mechanism designed for smooth, quiet, and continuous self-priming fluid circulation.
2. Integrated high-precision pressure regulating valve configured for the 6 to 25 bar (-3 stage) operational window.
3. Robust mechanical shaft seal configuration rated for high-temperature media up to 180 °C.
4. Right-hand (Clockwise / DC) rotation orientation when viewed facing the pump shaft.
5. High compatibility with heavy, light fuel oils, and self-lubricating hydraulic liquids up to 450 mm²/s viscosity.

Applications

• Marine diesel engine heavy fuel oil (HFO) and marine gas oil (MGO) booster modules.
• Industrial oil burner fuel supply networks and pre-heater skids.
• Centralized industrial lubrication and circulation systems.
• Hydraulic fluid transfer and auxiliary cooling-lubrication loops

Compatibility & Equipment Models

Compatible with standard industrial burner lines, marine auxiliary engine fuel units, and hydraulic auxiliary circuits requiring Safag/Danfoss NV-series architecture.

Directly matches systems requiring right-rotation (DC) internal gear pumps with integrated return connections.

Frequently Asked Questions

The main difference between IC and DC rotation codes on Safag Danfoss pumps is the direction of rotation?

The DC designation is for a right hand (clockwise) shaft rotation. IC is for a left hand (counter-clockwise) rotation looking at the pump shaft extension. Check your drive motor rotation before mounting it.

Does the Safag Danfoss 576 NVBGRMDC-3 run on light diesel and heavy fuel oil (HFO)?

Yes. The pump is compatible with self-lubricating fluids, heating fuels and light/medium oils, up to a maximum viscosity of 450 mm 2 /s, provided that the fluid temperature is maintained below the 180 °C threshold limit.

What is the maximum working pressure for this specific model of the NV series?

The internal gear design can handle pressures up to 40 bar, but the integrated NV-series control valve is generally sized for accurate control loops up to 30 bar. Always that your operational parameters are within the precise relief valve spring range installed.
