Introduction
The WDBF progressive distributor is a plate-type grease divider designed for heavy-duty conditions including mining, port, construction machinery and general factory equipment. It delivers metered grease sequentially to multiple lubrication points in centralized lubrication systems.
Featuring modular stacked plates, it can be configured with different metering plates per lubrication-point grease requirement and supports multi-stage master-slave series connection for secondary/tertiary oil distribution. Every outlet integrates a safety relief valve, with excess grease drained via overflow ports, ensuring stable, quantitative grease supply for friction points.

Features/Equipment characteristics
● Modular stacked segment structure: Different metering segments can be selected and combined flexibly according to required grease quantity of different lubrication points.
● Multi-stage series connection available: Support master-slave cascade connection to realize secondary or tertiary grease distribution for complex lubrication layouts.
● Built-in safety valve for every outlet: Excess grease will overflow from overflow port under overpressure condition to protect pipeline and components.
● Designed for heavy-duty mining conditions: Robust structure adapts to harsh working environment of mining and construction machinery.
● Optional cycle indicator rod: Visual feedback for divider working status; indicator can be omitted upon request.
Our Advantages
1.Customizable flexible configuration: Various displacement segments and port-merging options to match different lubrication flow requirements; number of lubrication points ranges from 6 up to 20 points.
2.Full-range over-pressure protection: Every outlet is fitted with independent safety valve, avoiding pipeline damage caused by blockage of single lubrication point.
3.Heavy-duty industrial design: Optimized for mining, port and construction machinery with strong anti-pollution and anti-vibration capability.
4.Multi-level distribution capability: Realize multi-stage progressive grease distribution by cascading dividers, suitable for large-scale centralized lubrication system.
5.Clear status monitoring option: Equippable indicator rod for quick on-site judgement whether the divider is running normally.
FAQ
Q1: No pressure at inlet and no grease output during operation.
A: Air trapped in inlet pipeline or grease tank is empty. Disconnect inlet pipe, start lubrication pump and verify whether grease comes out from pump side. Eliminate air or refill grease accordingly.
Q2: Can I mix different types of lubricating grease for this divider?
A: Do not mix different lubricants. Mixed greases may generate unpredictable chemical changes and lead to divider blockage or seal failure.
Q3: Can I use grease containing graphite / molybdenum disulfide / calcium base solid particles?
A: Grease with graphite, molybdenum disulfide, calcium carbonate or calcium hydroxide particles is forbidden. Hard particles will accelerate wear of piston and seals, cause seizure or premature system failure. Consult our technical team before using lubricants with solid additives. Grease containing graphene will aggravate component wear and lead to warranty reduction.
Q4: Can I swap pistons between different segments during maintenance?
A: No. The piston and bore are precision matching paired parts. Inter changing will cause leakage, metering error or jamming. Keep original matching relationship during disassembly and assembly.
