What is grease pumps?
Grease pumps are mechanical devices used to deliver high-viscosity lubricants under pressure in industrial, automotive, or workshop environments. They are essential for ensuring precise grease flow in maintenance, machinery lubrication, and equipment servicing tasks. Common variants include grease dispensing systems, pneumatic grease guns, electric grease pumps, and high-pressure lubrication equipment.
Products you’ll find in this category
Within the grease pumps category, you will find various types of grease guns—manual, electric, air-operated (pneumatic)—designed for use with cartridges, pails, or large drums. There are heavy-duty electric pumps designed for large-capacity drums, desktop or trolley systems for mobile grease supply, as well as accessories such as control valves with rigid or flexible outlets, rubber hoses meeting SAE standards, and flow or metering tools to monitor grease delivery. Capacity, power supply, and delivery method vary among the items displayed.
Applications & industry use cases
These products are used across automotive repair shops, industrial maintenance, and agricultural servicing where lubrication precision and consistency are critical. Electric drum-mounted grease pumps serve high-volume applications such as fleet workshops or manufacturing plants. Pneumatic and hand-operated grease guns are used for equipment servicing, fittings, bearings, chassis and hydraulic joints. Accessories such as control valves and SAE 100 R2AT hoses help in custom setups or retrofit lubrication circuits. They are part of broader lubrication equipment and grease delivery systems.
Technical guide to grease pumps
Grease pumps are designed to overcome resistance in lubrication circuits and deliver grease at controlled pressure and flow rate. Key technical characteristics include working pressure (often measured in bar), flow rate (grams or millilitres per minute), power source (electric voltage or pneumatic supply), capacity of the grease reservoir (e.g., cartridges, pails, drums), hose diameter, and outlet style (rigid or flexible). For example, an electric grease pump for a 180-kg drum may deliver up to 1,200 g/min at 200-bar pressure under 400 V supply. A pneumatic grease gun might offer stroke-dependent supply, such as approximately 4 g per stroke, and pressures around 260 bar. Accessories may comply with SAE standard 100 R2AT for hoses, and working pressures up to 800 bar for control valves. Industrial applications require consideration of ambient temperature range, grease type compatibility (thick-based, lithium, etc.), pressure and flow matching to equipment lubrication points, and material durability (hose reinforcement, seal resistance). Safety certifications like CE marking are relevant when pumps or accessories operate under high pressure.

Frequently Asked Questions about grease pumps
- What is the difference between electric and pneumatic grease pumps?
- Electric grease pumps use electric motors to drive grease at a continuous flow rate, often specified in grams per minute, and are suitable for drum or bulk lubrication. Pneumatic grease guns use compressed air, often offering stroke-based delivery. They can provide high pressure but require an air supply and may have lower flow rates compared to electric models.
- How do working pressure and flow rate affect performance?
- Working pressure determines how effectively the pump can force grease into tight lubrication points under resistance. Flow rate determines how quickly grease is delivered. A balance is needed: high pressure with low flow may be needed for small or blocked fittings, while high flow and moderate pressure are more efficient for large joints or bulk applications.
- What hose standard should I look for with grease pump accessories?
- Hose accessories often adhere to standards such as SAE 100 R2AT, which specifies reinforcement, pressure rating, materials, and temperature range. Such hoses typically handle pressures of several hundred bar and are resistant to abrasion, ozone, and environmental exposure.
- Why are control valves with rigid or flexible outlets used?
- Control valves manage and regulate grease flow, allowing precise application. Rigid outlets provide stability and control in direct access, while flexible hoses or outlets accommodate movement or reach into difficult or remote lubrication points. The choice depends on the shape and layout of equipment.
- What environmental factors should be considered when selecting grease pumps?
- Key factors include ambient temperature (which affects grease viscosity), exposure to dust or weather, compatibility of grease types, electrical supply or air source availability, and whether the pump must operate continuously or intermittently. Materials and pressure ratings must be selected to match these conditions for safe and reliable operation.
