IMO ACP 045K7 NVBP Triple Screw Pump

IMO Pump ACP 045K7 NVBP Triple Screw Pump (Unused New)

Engineered for critical maritime and industrial fluid transfer duties, the IMO Pump ACP 045K7 NVBP Triple Screw Pump (MPN: 640861) is a high-precision positive displacement pump. Designed by IMO AB, this heavy-duty unit utilizes a sophisticated three-screw configuration (one power rotor and two idler rotors) to deliver pulsation-free fluid displacement with minimal noise and vibration. Offered in Unused New condition, this unit is ideal for marine engine rooms, fuel booster modules, and hydraulic lubrication systems requiring continuous, high-reliability operation under demanding thermal and pressure constraints.

Technical Specifications

Key Features

1. Pulsation-Free Delivery: Hydraulically balanced screw profiles eliminate flow turbulence and fluid hammering, safeguarding downstream instrumentation.
2. Integrated Safety Relief Valve: Protects the system against overpressure events via an internal bypass loop set up to 16 bar.
3. High Viscosity Adaptability: Handles varied media from light diesel oil to heavy fuel oils and lubricating oils efficiently.
4. Robust Metallurgy: Nodular cast iron casing engineered to withstand harsh marine operational environments and continuous thermal cycles.
5. Low Acoustic Signature: Engineered precision tolerances keep operational noise and mechanical vibration to an absolute minimum.

Frequently Asked Questions

What is the primary function of the IMO ACP 045K7 NVBP pump?

It is a positive displacement triple screw pump engineered to transfer lubricating and fuel oils smoothly and continuously under pressures up to 16 bar in marine and industrial setups.

Can this pump handle high-viscosity heavy fuel oils (HFO)?

Yes, provided the viscosity remains within the operational envelope (up to 3500 cSt for fuel line seal arrangements) and pre-heating protocols are observed to maintain fluid flow characteristics.

What does “Unused New” condition signify for this marine asset?

It means the unit has never been installed or operated in a live system, retaining original factory tolerances and clearance parameters while being stored properly as a spare.

Is the rotation direction reversible on the ACP 045K7 NVBP?

No. This model is engineered for single-direction rotation (standard clockwise looking at the shaft extension). Running it in reverse will compromise lubrication delivery and damage internal seals.
