Product Overview
This high‑performance repair seal kit is engineered for Danfoss MPT044 series tandem axial piston hydraulic pumps, with a displacement of 44cc/rev. The kit includes complete shaft seals, O‑rings, gaskets, backup rings and critical sealing components, enabling full pump overhaul and routine maintenance.
Constructed with imported premium NBR nitrile rubber and FKM fluororubber as core materials, the seal set delivers exceptional oil resistance, high‑pressure resistance, wear resistance and aging resistance. It serves as a perfect direct replacement for original Danfoss seals, effectively resolving common issues such as external oil leakage, internal leakage and pressure drop. It extends the service life of MPT044 pumps under prolonged heavy‑load, high‑pressure and vibration‑intensive operating conditions.
