Model Code: IPNL /5-/80 (Material Number: 159.00021410)

This is a single-stage variant from the same Voith low-noise internal gear family (Serial Number 0020464527). Rather than being bolted into a tandem layout, this unit functions independently as a single-displacement line, optimized for targeted pressure preservation cycles or low-pressure fluid replenishment loops within the machine’s central manifold.

Model Code: IPV 6/-125/470 (Main Stage) combined with IPV/N 6/5-125/80 170 (Tandem Extension)
Serial Number: 20482158

It uses a special radial and axial sealing compensation design to minimize friction and thermal loss, ensuring near-silent operation and high volumetric efficiency under heavy workloads.

Model Code: IPV 6/-125/470 (Main Stage) combined with IPV/N 6/5-125/80 170 (Tandem Extension)

This specific tandem assembly pair is matched together under Serial Number 20463581. It features a high-displacement primary stage pump paired with a secondary internal gear stage via an integrated intermediate coupling block, allowing a single industrial motor to drive two separate, high-pressure hydraulic circuits simultaneously.

Model Code: IPV 6/-125/470 (Main Stage) combined secondary unit IPV 5/…

This high-performance tandem unit features two Voith internal gear pumps coupled together on a single drive shaft to deliver dual independent flow lines from one motor source. Engineered for maximum volumetric efficiency and near-silent operation, it utilizes a radial and axial sealing compensation design to continuously handle operating pressures up to 330 bar. It is widely used in high-demanding industrial environments, such as plastic injection molding machines and heavy hydraulic presses, to optimize multi-axis system speed and clamping force control.
