What Makes a Lubrication Pump Automatic
A pump becomes automatic when a controller decides when it runs, how long it runs, and what it does when something goes wrong. With it, dosing happens on a schedule or on machine activity, and the pump can report trouble instead of quietly skipping a cycle.
Declared Approach
| Control functions | Scope statement: pump-on and pump-off timing, interval programming, and pre-lube at start-up are the core programmable functions to compare across controller-equipped units. |
| Trigger modes | Scope statement: time-based cycling and machine-count or cycle-based triggering are the two main trigger families; some controllers support both. |
| Alarms | Scope statement: low-level alarm and external alarm output are the alarm functions to confirm for your installation. |
| Verification inputs | Scope statement: pressure switch, cycle switch, and divider sensor inputs are what allow a controller to confirm a dose rather than assume it. |
| Manual override | Scope statement: a manual-run button lets an operator command a dose without waiting for the next scheduled interval. |
| Units in the range | Scope statement: controller-equipped options include an electric lubrication pump station, the DC-220ST controller pump family, and an electric automatic chain oiler. |
What a Controller Actually Controls
Programming usually comes down to a short list. Interval programming sets how often a cycle starts. Pump-on and pump-off timing sets run and rest duration inside that cycle. Pre-lube at start-up pushes a dose before the machine begins moving.
Triggering can be time-based or tied to machine activity. A machine-count or cycle trigger doses every so many strokes rather than every so many minutes, so lubrication follows real use. A manual-run button stays useful during setup, after maintenance, or when an operator wants to confirm the pump turns.
Alarms are the difference between a silent pump and an accountable one. A low-level alarm tells you the reservoir is running down. An external alarm output passes that signal to a panel or indicator. Compare the electric lubrication pump station, the DC-220ST controller pump family, and the electric automatic chain oiler.
Verifying That Lubricant Arrived
This is the honest limit of the category. A timer alone cannot prove lubricant arrived at a bearing. If a line is blocked or a divider has stalled, a time-based controller will keep cycling and reporting normal operation.
Verification needs a feedback device: a pressure switch, a cycle switch, or a divider sensor. Those inputs let the controller distinguish a completed dose from a missed one. Ask which verification inputs a controller accepts before ordering.
Automatic or Manual: the Honest Cut
Automatic suits many points, scheduled doses, and hard-to-reach locations where a person will not reliably show up with a grease gun. Manual stays right for a few points, easy access, and sites with no power available.
If your requirement is still at the pump-body level, see grease pump types compared. If the automation case is clear, then contact us to confirm the configuration.
Commissioning an Automatic Pump
Commissioning decides whether the automation works in practice. Verify that interval and dosage settings match the point count and machine duty. Test the manual-run button and watch the pressure or cycle feedback respond.
Test the alarm path too: trigger a low-level condition and confirm the signal reaches wherever someone will see it. Power-loss and restart behavior are controller-specific, so confirm at ordering.
Frequently Asked Questions
What can the controller on an automatic lubrication pump program?
Typically pump-on and pump-off timing, interval programming, dosage per cycle, and pre-lube at start-up. Some models also program machine-count triggering and alarm thresholds.
Should I choose time-based or cycle-based triggering?
Time-based triggering suits steady duty where lubrication needs track the clock. Cycle-based triggering suits equipment whose use varies and where lubrication should follow actual operation.
Can a timer prove that grease actually arrived?
No, a timer only proves the pump ran, not that lubricant reached the point. Verification needs a pressure switch, cycle sensor, or divider sensor input.
What alarms are available?
Low-level alarm and external alarm output are the common functions to compare. Confirm at ordering which alarms your chosen controller supports.
What happens after a power cut?
Power-loss behavior, memory retention, and restart behavior are controller-specific and vary between models. Confirm at ordering so you know whether the interval resumes or restarts.
When is manual greasing still the right choice?
Manual stays right for a few points, easy access, and sites with no power. It also suits cases where physical inspection of each point is the real goal.
How many points can one automatic pump feed?
There is no universal count, because it depends on metering design, line layout, and lubricant grade. Confirm at ordering against your point list and duty cycle.
What should I check at commissioning?
Check interval and dosage settings against the machine duty, and test the manual-run button. Also trigger the alarm path and confirm the feedback sensor responds.
How should I state my requirements when ordering?
State point count, lubricant type and grade, trigger mode, and required alarms and sensor inputs. For a full quotation, send your requirements to our team.
