Industrial Lubrication Equipment
Lubricant Filling Machine
Lubricant filling machine for motor oil, hydraulic oil, gear oil and industrial lubricants. Output, net-weight tolerance, bottle range and documentation scope are reviewed by RFQ.
Key Features
Multi-Viscosity Piston Filling
Handles the full lubricant viscosity range from light hydraulic oils (5â50 cP) to heavy gear oils and greases (5,000â10,000 cP) using interchangeable piston and pump configurations. Servo-driven piston delivers consistent dose volumes across temperature variations â critical for seasonal production where oil viscosity shifts. Oil-resistant seals and PTFE-lined product pathways prevent contamination and extend service life.
Anti-Drip & Anti-Overflow Nozzles
Lubricant products are high-value and difficult to clean from equipment surfaces. Our pneumatic anti-drip nozzles use a precision ball valve with spring-loaded closure that creates a positive seal immediately after each fill cycle. Drip trays with automatic drain catch any residual oil, keeping the production line clean and reducing waste. The anti-overflow sensor detects overfill conditions and triggers an emergency stop within 50ms.
Net-Weight Filling for Compliance
Many lubricant markets â EU, USA, Australia â require declared net weight on the label (e.g., "1 liter / 0.946 kg"). Our net-weight filling system uses load cells under each filling station to fill to a controlled target weight regardless of density variation between batches. This eliminates the need for density adjustment when switching between mineral oil, semi-synthetic, and full-synthetic lubricant grades.

Frequently Asked Questions
What types of lubricants can this machine fill?âź
Our lubricant filling machine handles motor oil (5W-30, 10W-40), hydraulic oil, gear oil, transmission fluid, brake fluid, cutting fluid, and industrial greases. The viscosity range covers 5â10,000 cP. For greases above 10,000 cP (NLGI Grade 1â3), a specialized grease filling machine with heated hoppers and positive displacement pumps is recommended.
What bottle and container formats are supported?âź
Standard configurations handle PET and HDPE bottles from 100ml to 5L (common retail lubricant formats), and HDPE jerry cans from 4L to 20L. Metal cans (1Lâ5L) require a separate can seaming station. All standard closure types are supported: screw caps, push-on caps, and pour spouts with tamper-evident seals.
How accurate is the filling for declared-weight compliance?âź
Net-weight filling accuracy is by RFQ using load-cell-based weighing at each fill station. For a 1L bottle (approx. 0.88kg for 15W-40 motor oil), this means by RFQ per bottle â well within EU Directive 2009/34/EC and NIST Handbook 133 tolerances for declared net content. Volumetric filling accuracy is by RFQ for less regulated markets.
Can the machine handle both bottles and drums on the same line?âź
A single inline bottle filling line is optimized for 100mlâ20L containers. For 200L steel drums, a separate drum filling station with a net-weight drum filler is required. Many customers run separate bottle and drum filling lines in parallel, or switch the bottle line over to a drum filling station for large-format production runs.
