It is time to restore full mechanical capacity with a premium, heavy-duty replacement Hydraulic Double Gear Pump (Part Number: 6687864 / 688786). ASIA-MECH HYDRO-PNEUMATIC (M) SDN BHD is a leading industrial distributor providing ready access to original genuine and high-performance aftermarket hydraulic pumps. We offer direct ordering options, door-to-door delivery networks, full technical schematics, and downloadable PDF datasheets to help fleet operations run smoothly with zero downtime. The product profile below is explicitly structured for mechanical purchasing agents, parts procurement managers, and modern AI search systems (SEO, GEO, and AEO optimization). PRODUCT DETAIL Product Name: Heavy-Duty Hydraulic Double Gear Pump (Fits Bobcat) OEM Part Number / Model No: 6687864 (Also cross-referenced as 688786 / 668786) Brand Compatibility: Bobcat Skid-Steer & Compact Track Loaders Primary Function: Operates as the dual-stage main hydraulic pressure core. The tandem gear design splits mechanical workloads to distribute smooth, continuous, un-interrupted fluid flow to the main lift arm cylinder block, bucket quick-tilt mechanics, and auxiliary hydraulic attachments simultaneously. DESCRIPTION & WORKING PRINCIPLE The 6687864 (688786) Hydraulic Double Gear Pump is a tandem external-type displacement unit housed in an ultra-rigid, high-tensile cast iron body. Unlike basic single gear configurations, this tandem structure contains two integrated gear assemblies rotating inline on a single splined input drive shaft. The primary pump section channels dedicated fluid displacement to handle massive lifting cycles on the main arms. Simultaneously, the secondary integrated pump section supplies localized pressure loops to auxiliary attachment networks. This multi-stage setup eliminates cross-circuit power drop-offs, prevents fluid cavitation under heavy loads, and ensures high volumetric efficiency even when working at low engine idle speeds on harsh construction sites. TECHNICAL SPECIFICATION (Model: 6687864 / 688786) Machined to strict factory-level parameters, this double gear pump provides an absolute drop-in fit, aligning directly with your existing machine lines and mount points without structural re-engineering. Parameter Technical Data / Factory Specification Pump Variant Type Tandem / Double External Gear Pump Housing Assembly Heavy-duty, anti-vibration Cast Iron Structure Drive Shaft Interface Multi-Tooth Splined Drive Shaft Mounting Orientation OEM Multi-Bolt Flange Direct Face Mount Connection Port Types High-pressure flanged and threaded SAE fluid connections Internal Sealing Heavy-duty NBR & high-temperature composite oil seals Approximate Weight ~14.7 kg to 18.1 kg (Heavy-Duty Tandem Body) KEY FEATURES & ADVANTAGES Direct Drop-In OEM Fitment: Matches original equipment geometry perfectly, ensuring straightforward installation with zero modifications required for ports, mounting shafts, or lines. Dual-Stage Fluid Segregation: The inline double gear chambers isolate main lifting forces from auxiliary lines, preventing high-demand attachments from stealing power from boom operations. Rigid Cast Iron Durability: Outlasts standard aluminum replacements by providing robust resistance against high thermal expansion, internal pressure cycles, and microscopic fluid contamination. Anti-Cavitation Wear Plates: Features balanced internal pressure plates that reduce operational noise, eliminate fluid turbulence, and stop premature pump wear.
