Automatic Grease Lubrication Systems - Complete Guide & Products

An automatic grease lubrication system feeds every bearing on a machine or production line from one pump station, metering grease on a timed cycle instead of a worker with a grease gun. It is the standard answer wherever lube points are numerous, hot, guarded, or spread along long lines: production machinery, crushers and conveyors, trucks and excavators, steel and paper plants.

IsoHiTech builds these systems around four distribution families — progressive, single-line, dual-line, and single-point lubricators — with pumps from 24V DC chassis units to 40 MPa dual-line plants, timer controllers, and reservoirs from 2 to 100 liters. The products below cover the common configurations; the selection table, system comparison, and FAQs underneath the grid explain how to match a system to your machinery.

How to Choose an Automatic Grease Lubrication System

Five variables decide the configuration:

Selection factor	What to check
Lube points	Up to ~20 points: single-point lubricators or a compact progressive pump. 20–100 points: progressive metering or single-line injectors. Hundreds of points along long lines: dual-line.
Working pressure	14.7–25 MPa suits vehicle and machine progressive systems; 31.5–40 MPa is the class for dual-line plants with long pipe runs.
Reservoir	From 0.4L vehicle tanks to 100L plant stations — size by point count × per-point volume × refill interval.
Control	Integrated pump timers (4 min–15 h intervals) or standalone lubrication controllers for duty cycling, alarms, and low-level signals.
Grease grade	NLGI 000–2 covers most automatic systems; confirm each pump’s grade range before specifying.

The automatic grease system types guide works through each family in depth.

System Types at a Glance

Family	How it distributes grease	Best for
Progressive	Divides pump output across metering sections in sequence; a blocked point halts the cycle and can raise an alarm	Machines and mobile equipment needing exact per-point metering
Single-line / SLR	Pressurizes a line that charges injectors; injectors discharge on pressure release	Large point counts, long distances, grease or oil service
Dual-line	Two mains alternately pressurized; each feeder valve serves its own point group	Plants with hundreds of points, long runs, harsh environments
Single-point lubricators	Self-contained canisters feed one bearing for months untended	Remote or isolated points; the first step up from manual greasing

Automatic Grease Lubrication System FAQs

How much does an automatic grease lubrication system cost?

Price scales with point count, pressure class, reservoir size, and controls: a set of single-point lubricators or a compact DC progressive pump sits at the low end, while a 40 MPa dual-line plant with standby pump and controllers sits at the top. Because every installation is sized to the machine, IsoHiTech quotes per project — send the point count and grease grade through the contact page for pricing.

What is the difference between an automatic grease lubricator and a lubrication system?

A lubricator is one self-contained canister feeding one bearing; a system is a pump plus distribution network feeding many points from one station. Lubricators suit isolated points — see the single-point lubricators category — while systems cover whole machines.

Which system type fits heavy equipment?

Can an automatic system meter grease exactly at every point?

Yes — that is the core of a progressive design. Metering sections divide the pump output into fixed per-stroke volumes, so each bearing receives its specified dose every cycle, and a blocked point stops the sequence where an alarm can catch it.

Is an automatic grease pump by itself a complete system?

No. The pump is the heart, but a working system also needs distributors or injectors, a controller or timer, and the fitting and hose network. The pump models above pair with the progressive distributors and controllers listed in their categories.
