Product Structure & Components

Grease Reservoir / Tank: High-capacity storage container (available in transparent engineering plastic or heavy-gauge steel) designed to hold and protect the lubricant supply.

Drive Motor / Power Unit: High-torque electric motor, pneumatic air motor, or manual leverage system that provides the mechanical driving force.

Pumping Element & Piston: Precision-machined reciprocating piston or plunger mechanism that draws grease from the reservoir and pressurizes it.

Check Valves (Inlet & Outlet): One-way valves that regulate fluid direction, ensuring smooth suction and preventing backflow during the pressure cycle.

Pressure Relief & Safety Valve: Built-in mechanical safeguard that automatically releases excess pressure to protect the pump and distribution piping.

Discharge Outlet Port: Standardized threaded connection point where high-pressure grease is fed into external distribution lines or hoses.

Pressure & Flow Rate

High-Pressure Generation: Generates substantial output pressure to overcome line resistance and open high-pressure injector valves.

Controlled Flow Volume: Designed to provide precise, metered delivery rates tailored to the exact friction requirements of heavy industrial machinery.

Pressure Stability: Maintains consistent line pressure across extensive distribution networks without erratic surging.

Power Supply & Drive Options

Electric Drive: Multi-voltage industrial motors (12V/24V DC for mobile equipment; 220V/380V AC for fixed plants).

Pneumatic Drive: Air motor assemblies requiring standard workshop or plant compressed air supply lines.

Manual Leverage: Ergonomic mechanical levers designed for low-frequency or emergency lubrication tasks.

Lubricant Compatibility

NLGI Grease Grades: Fully compatible with standard industrial greases ranging from soft NLGI #000 up to heavy NLGI #2 formulations.

Specialty Lubricants: Handles synthetic greases, high-temperature greases, and extreme-pressure (EP) additives efficiently without separation.

OEM / ODM Customization

Tailored Engineering: Customized reservoir volumes, specific mounting footprints, and specialized outlet port configurations.

Electrical Adaptations: Custom motor voltages, pre-wired control harnesses, and integrated PLC timer modules.

Branding & Packaging: Laser-etched nameplates, customized corporate logos, and heavy-duty export-grade packaging.

Standards & Certifications

Global Compliance: Manufactured in strict accordance with international quality and safety management systems.

Certifications: Units carry CE markings, RoHS compliance documentation, and standard IP-rated dust/water ingress protection.

FAQ

Q: What is a pressure grease pump?

A: It is a mechanical or motorized device designed to store and deliver high-viscosity lubricating grease under high pressure to industrial machinery bearings.

Q: What maximum pressure can these pumps produce?

A: Our standard heavy-duty pressure grease pumps are capable of delivering working pressures up to 5,800 PSI (400 Bar), depending on the model.

Q: Which NLGI grease grades are compatible with your pumps?

A: Our pumps are engineered to handle standard industrial greases ranging from NLGI #000 up to heavy NLGI #2 formulations.

Q: Can these pumps be integrated into automated centralized lubrication systems?

A: Yes, they are specifically designed as the primary power source for progressive, single-line, and multi-point centralized automatic lubrication networks.

Q: What power supply options are available?

A: We offer flexible drive options including 12V/24V DC electric motors, 110V/220V/380V AC industrial motors, and compressed air pneumatic drives.

Q: How do I prevent the pump from over-pressurizing?

A: Every pump features a built-in adjustable pressure relief or safety valve that automatically discharges excess pressure to protect lines and fittings.

Q: What should I do if the pump stops delivering grease?

A: First, check if the reservoir is empty. If full, bleed any trapped air pockets or inspect the internal check valves for blockages caused by contaminated grease.

Q: Do you offer custom OEM modifications?

A: Yes, we provide full OEM/ODM services, allowing you to customize reservoir capacities, motor voltages, outlet configurations, and private-label branding.
