Introduction
The WDS-I electric lubrication pump adopts a reliable plunger structure and is configurable with 1 to 5 output ports.
- Single outlet version: Matches single-line centralized lubrication systems;
- 2–5 outlet versions: Compatible with multi-line lubrication systems.
Each outlet can be directly connected to progressive grease distributors or individual lubrication points for direct grease filling. Built with a fully enclosed sealed housing, the pump boasts outstanding waterproof and dustproof performance, perfectly fitting outdoor and exposed operating environments. It also supports flexible power supply options to meet diverse on-site power conditions.

Features/Equipment characteristics
- Optional low oil level sensing module, which can real-time monitor the residual grease volume inside the oil drum and send out alarm signals when the grease is insufficient.
- Wide working temperature range (-40℃ ~75℃), suitable for 0#–2# grease; optional 2L–15L oil drums and multiple displacement options.
- IP65 fully sealed design, dustproof and waterproof, applicable to outdoor and harsh construction, mining, port and wind power working conditions.
- Standard maximum working pressure up to 35MPa, overflow pressure set at 28MPa, stable high-pressure grease supply, matching long-distance and multi-point heavy-duty lubrication demands.

FAQ
Q1: Is maintenance convenient for the pump core?
A: The pump core adopts a modular split structure. Wearing parts including check valve spools and sealing rings can be replaced separately. Detailed disassembly and cleaning guidelines are provided in the operation manual.
Q2: The pump runs but no grease comes out, what should I check?
A: 1. Check aged/over-viscous grease or blocked filter;
2.Clean or replace faulty check valve;
3. Inspect piston wear causing internal leakage;
4. Clear blocked distributor or pipeline.
Q3: Key notes for pipeline installation?
A: Keep pipes short with fewer elbows; cut pipes vertically without deformation; remove all internal debris; fasten pipes with pipe clamps; ensure no twisting of high-pressure hoses.
