Description

KCB Gear Oil Pump Product Details
1. Product Overview
The KCB gear oil pump is a universal industrial positive displacement fluid conveying equipment. Different from diaphragm pumps and submersible pumps, it realizes stable and continuous material delivery through volume change caused by precision gear meshing. With a modular multi-material customized system, it adapts to ordinary oil products, low-flash-point hazardous liquids, corrosive fluids and food beverages. It supports a wide viscosity range of 5-1500cSt and a maximum temperature resistance of 300℃.
Equipped with core advantages of medium self-lubrication, strong self-priming, built-in overload pressure relief and flexible shock absorption, it requires no pre-filling and no additional lubricants. Featuring stable operation, low energy consumption and maintenance-free performance, it is widely used in petrochemical, shipbuilding, food light industry, electromechanical lubrication and industrial fluid circulation fields, serving as a standard core equipment for industrial fluid transportation and pressurization.
2. Core Product Advantages
Multi-material Customization, Full-range Medium Adaptation
The replaceable material structure breaks the limitation of traditional single-function oil pumps. Cast iron gears are suitable for heavy oil, diesel oil and lubricating oil; copper gears safely deliver low-flash-point volatile liquids such as gasoline and benzene without explosion risks; stainless steel versions adapt to beverages and weakly corrosive fluids with clean and pollution-free delivery. It is applicable to all flexible media without hard particles and fibers.
Medium Self-lubrication, Zero Consumables & Maintenance-free
The unique internal flow channel design realizes closed-loop lubrication of gears, bearings and transmission parts through the conveying medium. No additional lubricating oil or grease is required, avoiding medium pollution caused by external lubricants. It eliminates regular maintenance procedures, greatly reducing operating costs and downtime for continuous industrial operation.
Original Strong Self-priming Performance, Start Instantly
The precision gear meshing structure forms stable negative pressure in the pump cavity with excellent self-priming capability. No manual liquid pre-filling or pipeline air emptying is needed, realizing one-click startup and rapid pressure building. It adapts to complex working conditions such as high-level installation, long-distance suction and intermittent start-stop with simple operation and high fault tolerance.
Built-in Safety Valve, Automatic Overload Protection
The integrated safety pressure relief valve intelligently releases pressure when the pipeline is blocked or overloaded, balancing internal cavity pressure and preventing gear and shaft seal damage caused by high pressure. It effectively avoids pump stalling and burnout faults without manual intervention, improving equipment stability and service life.
Three Optional Seal Types, Full-condition Sealing
Three mainstream sealing structures are optional: skeleton oil seal for conventional normal-temperature oil with cost-effective and easy replacement; mechanical seal for medium-high pressure and slightly corrosive conditions with zero leakage; packing seal for high-temperature and heavy-load conditions with excellent temperature and pressure resistance. It solves leakage and aging problems in all working scenarios.
Flexible Coupling Transmission, Anti-impact & Installation Tolerance
The elastic coupling automatically compensates for minor coaxial deviation during installation, reducing debugging difficulty. It effectively buffers hydraulic impact and pressure fluctuation during operation, weakens transmission vibration and load impact, protects gears and motors, and ensures smoother and more stable equipment operation.
Wide Temperature & Viscosity Compatibility
The standard model stably delivers media with viscosity of 5-1500cSt and temperature below 200℃. The special high-temperature resistant model withstands medium temperature up to 300℃, adapting to high-temperature heat conduction oil, hot melt oil and high-temperature chemical media. It covers full-range flexible fluid working conditions.
Compact Structure, Low Energy Consumption & Easy Maintenance
The streamlined compact structure occupies small installation space, suitable for embedded equipment and narrow workshop scenarios. Heat-treated gears feature high hardness and wear resistance. The optimized oil return groove reduces bearing load and wear, improves conveying efficiency and saves energy. With few vulnerable parts, it is convenient for disassembly and overhaul with low long-term maintenance costs.
3. Working Principle
The KCB gear oil pump is a positive displacement pump. A pair of precisely meshed gears rotate synchronously, and the periodic volume change of the pump cavity realizes fluid conveying. The increased volume on the gear disengagement side forms negative pressure to suck in media; the compressed volume on the meshing side forms positive pressure to discharge media stably and continuously.
The whole operation process realizes self-lubrication through conveying media. The built-in safety valve controls cavity pressure and releases overload pressure. Matched with flexible coupling shock absorption and multi-type sealing structures, it achieves stable, leak-free, low-wear and maintenance-free continuous conveying for complex fluid conditions with diverse materials, temperatures and viscosities.
4. Application Scenarios
Focusing on multi-medium versatility, circulating pressurization, high-temperature conveying and long-term maintenance-free operation, the KCB gear oil pump covers flexible fluid conveying scenarios in oil, chemical, food, heavy industry and electromechanical industries.
Petrochemical Industry: Conveying and pressurization of heavy oil, diesel oil, lubricating oil and heat conduction oil; closed delivery of low-flash-point hazardous liquids such as gasoline and benzene; circulation and transfer of various medium and high-temperature chemical flexible media.
Shipbuilding & Heavy Industry: Oil supply for ship lubrication systems, cabin oil circulation, hydraulic oil delivery for heavy equipment, and fuel supply for field units, adapting to bumpy, impact-resistant and continuous operation conditions.
Food & Light Industry: Custom stainless steel models for conveying beverages, low-concentration syrup and weakly corrosive light industrial media, meeting food-grade delivery standards with no residue and no pollution.
Electromechanical Equipment Supporting: Continuous oil supply for lubrication systems of machine tools, generator sets and industrial equipment, and pressure stabilization of hydraulic systems to ensure long-term stable operation of mechanical equipment.
Industrial Oil Transportation: Pipeline oil pressurization, tank material transfer, workshop medium circulation and high-temperature hot melt fluid transportation, adapting to complex working conditions of high and low viscosity and wide temperature range.
5. Product Summary
With the core strengths of full-range multi-material adaptation, medium self-lubrication maintenance-free, built-in overload self-protection, flexible anti-impact performance, wide temperature and viscosity compatibility, and strong self-priming capability, the KCB gear oil pump solves the pain points of traditional oil pumps such as cumbersome maintenance, single working condition, easy damage and difficult startup. It balances safety, stability, economy and versatility, becoming the preferred standard equipment for flexible medium conveying, pressurization, circulation and lubrication in various industries.
