Description

HENGYUHANG 3PD2F Gear Pump – Reliable Tandem Hydraulic Gear Pump Replacement for Danfoss SNW Series

The HENGYUHANG 3PD2F hydraulic gear pump is engineered as a professional tandem hydraulic gear pump and serves as an effective replacement for Danfoss SNW series double pumps. This hydraulic gear pump replacement follows the same installation standard and performance level as Danfoss SNW3NN, SNW2NN, and SNW1NN tandem gear pumps, allowing customers to complete substitution without changing the original hydraulic system.

As an experienced OEM hydraulic gear pump manufacturer, HENGYUHANG focuses on producing high efficiency gear pump for hydraulic system with stable flow output, low noise, and long service life. The 3PD2F tandem pump is an ideal choice for buyers seeking a cost-effective replacement for Danfoss hydraulic gear pump used in construction machinery and industrial equipment.

Functions of Hydraulic Gear Pump

The HENGYUHANG hydraulic gear pump 3PD2F performs the following functions:

  • Provide continuous pressure oil source as a standard hydraulic gear pump

  • Realize two independent flow outputs in tandem hydraulic gear pump configuration

  • Distribute power for steering circuit and working circuit

  • Maintain strong self-priming ability of gear pump for hydraulic system

  • Reduce pulsation and internal leakage of double pump

Compared with Danfoss tandem hydraulic gear pump, the 3PD2F pump keeps equivalent delivery characteristics and can directly replace Danfoss SNW1NN SNW2NN SNW3NN double gear oil pump in original equipment.
