12L/3gal Pneumatic Grease Pump

We engineer WYMA 12L/3gal air-operated grease pumps to withstand heavy industrial use. You will find that MD-CE certification on every unit to meet EU safety and durability requirements. Since we manufacture factory-direct, our team controls every production stage, this eliminates distributor markups and third-party handling. What does that mean for your operation? You receive durable equipment without inflated costs. We maintain consistent quality because we never outsource critical manufacturing steps. Ample inventory guarantees fast global delivery, while easily replaceable components and dedicated support simplify long-term maintenance. Proven at major industrial expos like CIHF, CISMEF, and AIFME, our products are engineered for leak-resistant performance and efficient grease transfer. Trust WYMA for durable, budget-friendly air grease lubricators built on proven industry expertise.

Product’s Applications

We build our WYMA 12L/3gal air grease pump series for specific industrial challenges, all four models require inverted grease filling.

Need cost management? Our WM-3812R Round Pump Head model and WM-3815 Small Round Head model give you the best cost-effective solutions. Both deliver 50:1 oil pressure ratios and pair with standard 50L air compressors. You will get a stable grease output of 1.2L/min and 0.9L/min respectively. Use the WM-3812R when refilling room-temperature grease on vehicles in arctic conditions. Prefer lightweight options? The WM-3815 handles occasional maintenance for tractors in Mediterranean or Southeast Asia's humidity. Remember both models recommend using NLGI #0-2 grease during winter operations.

For extreme condition, we engineered two heavy-duty performers. The WM-3812H Square Pump Head model pushes 1.5L/min output. It need to be paired with a 70L+ air compressors because that 80:1 pressure ratio demands serious air consumption. In what application scenarios can this model be selected? When your workshop handles continuous 300°C grease applications or pumps thick industrial lubricants daily. Our WM-3814 balances mobility and force. Its 75:1 pressure ratio generates 40-50MPA output while keeping weight manageable. Though delivering 0.9L/min flow rate, its efficiency surges when paired with 70L air tanks, proving optimal for high-altitude / low-temperature operations (such as wheel hub maintenance for mining trucks in Chilean copper mines) and mobile airport maintenance scenarios.

By introducing detailed specs for each model of WYMA 12L/3gal pneumatic grease pump series, we provide customers with a more detailed understanding of its application scenarios, covering light machinery lubrication to the world's harsh industrial conditions.

Product’s Feature And Details

WYMA 12L/3gal Pneumatic Grease Barrel Pump vs. Other Brands Key Advantages:

Filtering Capacity & Pressure Control

Other Brands: Basic pressure valves let moisture enter, causing rust and the valve does not display intake pressure

WYMA: Integrated oil-water separator + precision regulator + unique honeycomb filter blocks impurities, ensuring dry airflow for rust-free operation.The sensitive pressure regulating valve can regulate pressure accurately and display the intake pressure.

Grease Gun Flexibility

Other Brands: Ordinary grease guns cannot be rotated arbitrarily, which is inconvenient to use.

WYMA: The universal aluminum gun is connected with two flexible joints and can rotate 360 degrees for oiling.

Quick Use

Other Brands: Complex to use

WYMA: Easy to use. First insert the suction cup into the barrel, then connect the oil pipe, oil gun, and air pipe in sequence, and finally adjust the pressure gauge to 0.6-0.8Mpa, then can use it.

Oil Pipe

Other Brands: Single-layer Pipe burst under high pressure.

WYMA: Steel-braided triple-layer Pipe resist 4000PA pressure and corrosion, 4.0m/4.9m/6m/10m are also available.

Mobility & Stability

Other Brands: Thin wheels wear quickly.

WYMA: 13mm thickened barrel + swivel casters ensure smooth outdoor mobility.

Excellent Pump Performance

Other Brands: Single piston pump, weak suction struggles with cold/thick grease.

WYMA: Industrial grade precision casting high pressure large double bar power oil pump head, strong suction and large flow rate, can pump butter 10 meters away. Rely on precision plunger oil inlet, some modles can handles -20 Celsius to 300 Celsius grease, it also supports 365 days of reliable operation.

Seal & Efficiency

Other Brands: Leaky seals waste grease.

WYMA: 280mm nylon suction cup ensures 100% grease uptake, zero waste.

Maintenance

Other Brands: Complex upkeep.

WYMA: Add only 3 drops pneumatic lubrication before and after use can extends lifespan.

Outperform ordinary 12L/gal Pneumatic Grease Bucket with WYMA’s industrial-grade power, precision engineering, and rugged design. Built for speed, durability, and extreme conditions, our system delivers faster, cleaner lubrication. Elevate efficiency—choose WYMA.
