HELI Forklift Hydraulic Pump Seal Ring – 1-3 Ton

HELI Forklift Hydraulic Pump Seal Ring — 1-3 Ton Forklift Trucks

This hydraulic pump seal ring is an OEM replacement sealing component for HELI 1-3 ton forklift hydraulic pumps. Weighing 0.15 kg, this precision seal ring provides the critical shaft or housing seal function within the hydraulic pump assembly — preventing hydraulic oil leakage at the pump shaft or between pump housing sections. Manufactured with long working life material formulation, this seal ring withstands the continuous high-pressure operation and frequent start-stop cycles typical of forklift hydraulic pump applications.

This seal ring fits HELI forklifts in the 1-3 ton capacity range across diesel and LPG configurations where hydraulic pump sealing is required. The compact 12×12×10 cm package dimensions reflect the small but critical nature of this sealing component — a failed pump seal allows hydraulic oil to leak externally, reducing system pressure and contaminating the engine bay. Common failure indicators include: visible hydraulic oil leak at the pump shaft area (shaft seal failure), reduced hydraulic system performance across all functions (pressure loss from internal leakage), and oil contamination of the pump drive belt or surrounding components. The seal ring must be replaced promptly — continued operation with a leaking pump seal leads to pump cavitation, bearing failure, and complete pump destruction.

Installation requires removing the hydraulic pump from the forklift and partially disassembling the pump to access the seal location. The seal must be installed with the sealing lip oriented correctly toward the pressure side. Clean the seal bore and shaft surface thoroughly before installation — any contamination or surface damage will cause immediate seal failure. OEM, ODM, and customized service is available.
