Introduction
WDS-II is a heavy-duty electric grease pump engineered for automatic lubrication systems. Designed primarily for dual-line systems and compatible with pressure relief and progressive setups, it combines a precision mechanical valve with high pressure, large flow, intelligent control and high reliability as its core strengths. A transparent reservoir simplifies grease level monitoring, while a robust, fully sealed frame withstands harsh environments such as wind energy, construction and heavy machinery. Suitable for heavy industry, metal processing plants, mining and mineral processing, power plants and cement plants, this auto lube pump delivers consistent, automatic greasing that reduces downtime, lowers lubricant waste and extends equipment life.

Features/Equipment characteristics
- Modular design: Interchangeable sub-modules (pump, pressure, scraper, relief valve, directional valve) let you configure the automatic grease pump to match your application needs.
- Transparent reservoir: A see-through grease storage drum enables quick, at-a-glance checks of lubricant levels, so operators always know when to refill.
- Fully sealed construction: A weatherproof and dustproof build ensures reliable operation in harsh environments such as wind energy and construction machinery.
- Programmable control options: An optional built-in program controller and liquid level alarm enhance automation and safety monitoring for hands-free auto lube operation.
- Dual-system compatibility: Designed primarily for dual-line systems, with adaptability to pressure relief or progressive lubrication setups for flexible system design.

FAQ
Q1: Is the low oil level sensor necessary?
A1: It is not mandatory as standard equipment, but we strongly recommend installing it on an automatic lubrication system. The sensor actively monitors reservoir levels, triggers audible or visual alerts, and can send a signal to the controller to shut the pump down automatically, preventing damage from dry running. It is an essential accessory for protecting equipment assets and enabling preventive maintenance.
Q2: How do I choose the correct number of outlet ports?
A2: It depends on your application. A single outlet suits fixed-point greasing of one device, while multiple outlets (2–5) are ideal for centralized distribution systems that supply several machines or lubrication points. For most industrial auto lube setups, multiple outlets ensure balanced grease delivery. Our sales engineers can help you select the right model for your specific workflow.
Q3: Which grease grades and temperatures does the electric grease pump support?
A3: The WDS-II handles NLGI 0# to 2# greases and operates over a temperature range of -40°C to 85°C, covering most industrial environments and lubricant types.
