Hydrostatic Pump Shaft Seals for Merlo Telehandlers

Hydraulic oil leaks at the interface between the hydrostatic drive pump and the engine flywheel housing, drive system pressure drops, or air aeration indicate severe wear on the pump input shaft seal (simmering). A compromised shaft seal on the main hydrostatic travel pump causes efficiency loss in the drive transmission, fluid overheating, and risks severe pump failure. At PGA Technika, we supply heavy-duty hydrostatic pump shaft seals for Merlo telehandlers engineered to deliver reliable fluid retention under high rotational speeds and backpressures.

Our product range: Shaft simmerings, pressure rings, and pump seal kits

We supply high-quality replacements and original Merlo parts manufactured for high thermal endurance and fluid compatibility:

• Hydrostatic travel pump shaft seals (high-pressure simmerings) – radial shaft seals designed for the main input drive shaft of hydrostatic travel pumps.

• High mechanical resistance components – seals manufactured from specialized fluoropolymer elastomers (FKM/Viton, NBR, PTFE) resistant to elevated oil temperatures, pump case pressure surges, and continuous high-speed friction.

• Anti-extrusion backup rings & face seals – structural support components safeguarding seal lips against pressure spikes inside the pump housing drain circuit.

• Hydrostatic pump overhaul seal kits – comprehensive repair seal sets for travel pumps (Rexroth, Sauer Danfoss, Linde).

We supply Merlo telehandler parts compatible with Turbofarmer, Panoramic, Multifarmer, Roto, and compact series models.

Fast dispatch (24-48h) & downtime reduction

A leaking hydrostatic pump shaft seal leads to fluid loss and drive system aeration. Essential hydrostatic pump shaft seals are held in stock for 24-48 hour dispatch. As a dedicated Merlo parts supplier, we also arrange express factory orders for specialized hydraulic overhaul kits.

Accurate VIN-based Merlo parts verification

Hydrostatic pump shaft seals vary across production years by inner/outer diameters, width, seal lip geometry, and case pressure ratings depending on pump manufacturers (e.g., Rexroth, Sauer Danfoss, Linde). Utilizing the official Merlo parts catalog, our technical specialists will cross-check your machine’s VIN to guarantee a 100% correct component fitment.
