3L Grease Lubrication Pump
The 3L electric grease lubrication pump is designed to supply clean 000#–00# grease to compatible centralized lubrication systems. It combines a 3 L transparent reservoir, 90 W electric drive, gear-type pumping mechanism, pressure gauge, grease filling port, and automatic or semi-automatic control options.
The supplied product-family information indicates a nominal pressure of 4.0 MPa and a nominal flow rate of 0.5 L/min. Depending on the selected configuration, the pump may be supplied with digital timing control, manual activation, single- or dual-display control, or pressure-monitoring functions. It is suitable for machine tools, CNC equipment, injection molding machinery, punching equipment, packaging machinery, and industrial automation systems.
Product Introduction
The 3L electric grease lubrication pump acts as the grease supply unit in a centralized lubrication circuit. During operation, the electric motor drives the internal gear-type pumping mechanism, drawing grease from the reservoir and delivering it through the outlet to connected pipes, distributors, and metering components.
Compared with the 2 L version, the 3 L reservoir provides additional grease storage capacity for equipment requiring longer refill intervals or a larger centralized lubrication supply. Actual refill frequency depends on the programmed lubrication cycle, grease delivery volume, number of lubrication points, and machine operating time.
Automatic versions use a digital controller to manage lubrication and interval cycles. Semi-automatic versions allow the operator to initiate grease delivery through the control panel. A pressure gauge provides a visual reference during operation, while the transparent reservoir allows maintenance personnel to monitor the remaining grease level.
Final product selection should consider the required voltage, control method, grease consistency, operating pressure, outlet connection, pipe layout, distributor type, installation space, and number of lubrication points.

Product Features
3 L Transparent Grease Reservoir
The larger 3 L reservoir stores more grease than the 2 L version and allows operators to monitor the approximate grease level during routine inspections. It is suitable for systems where a larger reserve or longer interval between refills is preferred.
Automatic or Semi-Automatic Operation
Automatic versions can start and stop the lubrication cycle according to controller settings. Semi-automatic versions allow lubrication to be initiated manually through the control panel, giving maintenance personnel direct control over each cycle.
90 W Electric Drive
A 90 W motor powers the internal gear-type pumping mechanism. Electric operation reduces dependence on repeated manual pumping and supports centralized grease delivery to compatible machine lubrication circuits.
4.0 MPa Nominal Pressure
The product-family specification lists a nominal pressure of 4.0 MPa. Buyers should compare this value with the pipe length, grease consistency, distributor structure, metering components, and overall system resistance.
0.5 L/min Nominal Flow
The listed nominal flow rate is 0.5 L/min. The grease quantity reaching each lubrication point is controlled by the downstream circuit, including distributors and metering units.
Integrated Pressure Gauge
The pressure gauge provides a visible reference during operation and commissioning. It can help operators identify unusual pressure conditions, although the exact gauge range and accuracy should be confirmed.
Multiple Controller Options
Single-display, dual-display, semi-automatic, and pressure-monitoring configurations allow buyers to select a control method that better matches the machine design and maintenance procedure.
Product Application
The 3L electric grease lubrication pump is suitable for equipment requiring centralized and periodically controlled grease delivery. Its larger reservoir is particularly relevant where the lubrication system serves multiple points or where reducing refill frequency is important.

Packing, Storage, Handling and Transportation
Packing
Each 3L electric grease lubrication pump should be packed according to its control version, electrical configuration, and order quantity. The control panel, pressure gauge, motor, transparent reservoir, filling cap, outlet fitting, and mounting base require separate protection against impact and compression.
Protective film, foam cushioning, inner cartons, and reinforced outer cartons may be used to prevent movement inside the package. For bulk orders or long-distance sea transportation, additional pallet or wooden-case protection can be arranged according to the confirmed shipping requirements.
Before packing, the product model, reservoir capacity, automatic or semi-automatic configuration, display type, voltage specification, quantity, and supplied accessories should be checked.
Storage
Store the pump indoors in a dry, clean, and ventilated area. Keep it away from rain, high humidity, corrosive gases, metal dust, direct sunlight, and heat sources.
The pump should remain upright during storage. Do not place heavy cartons or equipment on the pressure gauge, controller, filling cap, or transparent reservoir. Keep the outlet connection and filling opening covered to prevent dust and foreign material from entering the grease circuit.
For extended storage, retain the original protective packaging and inspect the electrical components, reservoir, fittings, and external surfaces before installation.
Handling
Lift and move the pump by supporting its metal mounting base or main body. Do not carry it by the pressure gauge, electrical cable, control panel, filling cap, outlet fitting, or transparent reservoir.
Avoid dropping, overturning, collision, and strong vibration. Special care should be taken to prevent damage to the pressure gauge and deformation of the outlet connection.
When handling multiple units, use suitable cartons, pallets, or lifting equipment according to the total package weight. Do not drag unpacked pumps across the floor.
Transportation
The pump can be prepared for international express, air freight, sea freight, or rail transportation. The final packaging method depends on the order quantity, destination, transport route, and whether the shipment includes other lubrication-system components.
Packages should remain upright and securely fixed during transportation. Heavy products should not be stacked directly above the controller, gauge, or reservoir area.
Before shipment, LONGQIAO checks the model, control configuration, voltage information, quantity, accessories, visible condition, and packaging status. Exact package dimensions, gross weight, and units per carton are available after the final order configuration is confirmed.
