Simple, Reliable Fixed Displacement Pump for Consistent Flow in Hydraulic Systems.
A gear pump is the most common type of hydraulic pump—and for good reason. It uses two meshing gears (a drive gear and an idler gear) inside a tight-clearance housing. As the gears rotate, fluid gets trapped between the gear teeth and the housing, then carried from the inlet side to the outlet side. Gear pumps are fixed displacement, meaning each revolution delivers a consistent volume of fluid. Yagang gear pumps feature precision-machined cast iron housings, hardened steel gears, and durable bronze or aluminum bearing plates. They handle pressures up to 3,600 PSI continuously, with flows from 1 GPM to 100+ GPM depending on size and speed. Applications include log splitters, dump trailers, agricultural equipment, material handling, industrial machinery, and mobile hydraulics. When you need a simple, affordable, and tough pump, gear pumps are usually the answer.
Fewer moving parts mean fewer things to break. Yagang gear pumps have only two rotating components—drive gear and idler gear—plus bearings and seals. That simplicity translates to high reliability and low maintenance costs. When wear eventually occurs, replacement kits (gear sets, bearing plates, seals) are available to rebuild the pump rather than replacing the whole unit. Field repairs keep downtime short.
Some pumps lose efficiency at low or high speeds. Yagang gear pumps maintain good volumetric efficiency (typically 90–95%) from 500 RPM up to 4,000 RPM depending on model. Precision-ground gear profiles minimize internal leakage, while pressure-balanced bearing plates automatically adjust to maintain tight clearances as pressure rises. The result is consistent flow output whether the engine is idling or running at full throttle.
Gear pumps see dirt, heat, and pressure spikes. Yagang pumps are built with cast iron housings that resist distortion, hardened steel gears (through-hardened or case-hardened), and heavy-duty bearings that handle radial loads from belt drives or direct coupling. High-temperature seals (up to 250°F continuous) and optional stainless steel shafts for corrosion resistance are available. These pumps survive on log splitters, snowplows, construction equipment, and farm machinery.
Yagang hydraulic cylinders ensure precision motion control for automated production lines. They address the need for reliable, low-maintenance actuation in packaging, handling, and assembly systems, minimizing downtime in continuous operations.
For high-speed, repetitive cycles in CNC and stamping equipment, Yagang hydraulic cylinders provide exceptional accuracy and rigidity. They are engineered to combat wear and maintain positioning precision over long service life.
As the core power component, Yagang hydraulic cylinders deliver consistent, high-force output for molding and forging. They are built to withstand extreme pressure spikes and ensure stable platen movement, crucial for product quality.
In high-heat, high-shock mill environments, Yagang’s heavy-duty hydraulic cylinders offer robust performance for rolling and handling. Their design focuses on heat resistance and structural integrity to withstand punishing conditions.
Subjected to extreme abrasion and shock loads in crushers and kilns, Yagang hydraulic cylinders are built for toughness. Their robust design prioritizes seal protection and piston rod strength to maximize uptime in the harshest environments.

Gear pumps are the simplest and most affordable—fixed displacement, good for pressures up to 3,600 PSI, tolerant of contamination. Vane pumps are quieter and have better low-speed efficiency but are more sensitive to oil cleanliness. Piston pumps handle the highest pressures (5,000+ PSI) and offer variable displacement options but cost more. Choose gear pumps for cost-sensitive applications with moderate pressure requirements.
Yagang gear pumps cover displacements from 0.5 cc/rev to 100+ cc/rev. Continuous operating pressure is up to 3,600 PSI (250 bar) for standard models, with peak pressures to 4,500 PSI for intermittent duty. Flow output depends on displacement and drive speed—for example, a 10 cc/rev pump at 2,000 RPM delivers approximately 5.3 GPM. Speed range is typically 500–4,000 RPM depending on displacement and inlet conditions.
Yes. As an experienced OEM gear pump manufacturer, we produce pumps that meet or exceed original equipment specifications. Our engineering team works from OE part numbers, sample pumps, or customer drawings to replicate displacement, mounting flange (SAE 2-bolt, 4-bolt, ISO), shaft configuration (keyed, splined, tapered), port sizes and orientation (SAE, NPT, BSPP), and optional features (integral relief valves, inlet strainers, flow dividers). Reverse engineering for discontinued models is also available.
Our MOQ for standard gear pump models is typically 10–50 pieces depending on displacement and configuration. For custom or OEM orders, we offer flexible MOQ arrangements—including small-batch validation (5–10 pieces) before full wholesale procurement. Lead time for stocked models is 3–7 days after order confirmation. Custom orders typically require 15–25 days based on complexity, component availability, and quantity.
Absolutely. We provide comprehensive private labeling solutions for B2B clients, including pump housing marking with your brand logo and part numbers, custom paint colors, and branded packaging. For high-volume wholesale partners, we can also offer custom nameplates, serial number tracking, and modified port or mounting configurations exclusive to your distribution channel.
