Spectrum Bulk Oil Storage System - Essential Stack
The Essential Stack replaces drum chaos with a compact, ready-to-use bulk oil storage system. It gives you a cleaner, safer way to store and dispense lubricants without overcomplicating your lube room.
Simple. Reliable. Scalable.
A Clean Starting Point for Bulk Oil Storage
The Essential Stack focuses on the fundamentals; sealed tanks, controlled transfer, visual identification, and spill containment. It standardizes lubricant handling and reduces contamination risks while keeping the system cost-effective and easy to deploy.
It’s ideal for plants moving out of drum storage and into a more structured bulk storage approach.
Build What You Need
Pump Stack and Storage Stack
You get centralized pumping, clean dispensing, and expandable capacity without overbuilding or redesigning your space.
Pump Stack (Required)
Every Essential system begins with the Pump Stack. It powers the system and manages all fluid movement.
- Central industrial gear pump with expansion manifold
- Stainless-steel wands for clean transfer
- Manifold supports up to two Storage Stacks
- Drain valve allows line purging to reduce cross-contamination
Storage Stack (Capacity Expansion)
Storage Stacks increase volume without adding pumps or complexity.
- Adds two 65-gallon tanks per stack
- Connects directly to the Pump Stack
- Expands the system to 4 or 6 tanks total
- Keeps costs down while increasing storage
The Result
A modular, space-efficient bulk storage system that grows with your lubricant needs. Simple to deploy, easy to expand, and ready to work day one.
No lube room overhaul. No wasted hardware. Just the right amount of system.
Built for the Basics
Ideal for Plants That Need Clean, Organized Storage
Choose the Essential Stack when you:
- Want to eliminate 55-gallon drum storage
- Need standardized dispensing points
- Operate in temperature-controlled lube rooms
- Already use filtration elsewhere (transfer cart or offline system)
- Expect to expand lubricant storage over time
It’s the most economical option for cleaner handling without filtration.
Standard Features Across Every Spectrum System
Tank construction, spill containment, contamination control, mobility, and identification features are consistent across all Spectrum systems, so best practices stay standardized, even as capabilities scale.
What Makes the Essential Stack Different
Controlled Pumping
Ensures consistent drum-to-tank transfers and reduces spill risk.
Tank Isolation
Individual valves let operators select, isolate, or change tanks quickly.
Cross-Contamination Prevention
Drain valves and tank selection prevent mixing products.
Scalable Design
Add two tanks at a time without modifying the existing system.
Space Efficiency
Vertical tank arrangement reduces footprint compared to multiple drums.
