Product Overview
This high-performance repair seal kit is specially designed for Linde HPV091DW variable displacement axial piston hydraulic pumps, a mainstream main pump widely equipped on medium-sized excavators. The complete set includes shaft seals, O-rings, flat gaskets, backup rings, control piston seals and all supporting sealing components, fully supporting full overhaul and routine maintenance of HPV091DW pumps.
Manufactured with imported premium NBR nitrile rubber and FKM fluororubber as core sealing materials, matched with reinforced PTFE backup rings, this seal kit delivers outstanding oil resistance, high-pressure resistance, wear resistance and anti-aging performance. It acts as a perfect direct replacement for original sealing parts. The kit effectively solves common faults such as external oil leakage, internal leakage and system pressure drop, and extends the overall service life of HPV091DW hydraulic pumps under long-term heavy-load, continuous operation and vibration working conditions.

Key Selling Points
1. 100% Exact OEM Replacement.Fully compatible with original Linde HPV091DW hydraulic pumps with standard OEM dimensions. No cutting, grinding or extra modification is required. It supports fast direct installation for daily maintenance, field overhaul and emergency on-site repair, greatly reducing equipment downtime and labor costs.
2. Premium Imported Sealing Materials.Core sealing parts adopt high-performance FKM fluororubber and reinforced PTFE backup rings. The materials feature excellent resistance to hydraulic oil corrosion, pressure impact and fatigue deformation. It maintains stable sealing performance within the temperature range of -10°C to 80°C, adapting to complex construction site working environments.
3. Excellent High Pressure & Vibration Resistance.All sealing components have passed strict 34.3MPa high-pressure and long-cycle vibration simulation tests. It thoroughly eliminates internal and external leakage of the pump body, stabilizes the overall pressure of the negative flow control hydraulic system, and ensures stable flow and power output of the main pump during long-hour heavy-duty operation of excavators.
4. Complete All-in-One Repair Package.The kit is equipped with all sealing accessories required for full pump maintenance, including special seals for control assemblies. Integrated packaging unifies part management, simplifies inventory classification, shortens the overall repair cycle and cuts daily operation and maintenance costs of engineering equipment.
5. Strict Factory Quality Inspection.Every seal kit undergoes air tightness test, high-pressure durability test and aging test before delivery. All products comply with original factory technical standards, providing reliable long-term operation guarantee for excavator hydraulic systems.
6. Targeted Application Scope.Specially developed for Linde HPV091DW main pumps, widely applied on medium-sized excavators and related construction machinery:
Welcome to HOVOO, a Chinese seal factory. Production of PU, Rubber and PTFE seals. The seals include O-ring, piston seal, rod seal, Gray ring and gas seal.
