Grease Pumps
A grease pump moves grease from its container to the points — everything else is a choice of how. Air-driven pumps multiply shop air into high delivery pressure. Electric pumps run timed cycles for centralized systems. Hand pumps put muscle where no power exists. The fifty pumps cataloged under IsoHiTech span all three platforms, and this page routes you to the shelf that matches your machine.

The Three Platforms Compared
| Platform | Best at | Watch for |
|---|---|---|
| Pneumatic (air-driven) | High delivery pressure, bulk drums, non-stop workshop duty | Needs a real air line; ratio (e.g. 50:1) sets pressure |
| Electric | Timed cycles, progressive and dual-line systems, unattended machines | Voltage must match the machine; element is the wearing part |
| Manual (hand/foot) | Point work, no-power sites, low volume | Effort scales with pressure; follower plate saves the last quarter of the pail |
Grease Pump FAQ
What does a 50:1 air pump ratio mean?
It is the multiplication: 6 bar of shop air becomes roughly 300 bar at the grease outlet. Higher ratios give more pressure but slower delivery. Match the ratio to your hardest coupler and line length, not to prestige — over-ratioing wastes air and stiffens the hose handling.
Which platform suits a centralized system?
Electric, almost always. Centralized lubrication lives on timed cycles, and only an electric pump under a controller repeats them accurately unattended. Pneumatic belongs where a human already works; manual belongs where nothing else runs.
Does grease grade change pump choice?
Yes — NLGI #2 in cold weather is the classic case. Thick, cold grease behaves like a much higher pressure load, and a pump sized to its summer margin stalls in January. If winter NLGI #2 or #3 is your reality, size the pump one class up or heat the container.
One pump for the whole machine, or pump per system?
One pump feeds many points when a divider block distributes the flow — that is the progressive architecture behind the electric lines on this site. Points that need independent timing get their own single-point feed. Machine size decides: one pump per machine is the norm, per production line the exception.
Where do I start with a pump that already exists?
With its wearing part. Pump elements and couplings — see the pump elements shelf above — restore most “tired” pumps for a fraction of replacement. Send the pump model through the contact page and the team maps the element before you buy anything new.
