Grease Transfer Pumps
A grease transfer pump has one job: move thick grease from where it is stored — drum, keg, pail or 5-gallon bucket — to where it is used: a machine reservoir, a central system tank, or a dispensing point. It is not the pump that meters grease to bearings; it is the one that empties the container. Every unit on this page is cataloged for that duty.
Three drives do the work. Air motors run the SUREMATIC 18:1 class with 8 cc per stroke from a 2-liter follower. Electric units — DZG at 25 MPa and 6 ml/min on 220/380V, the Y6020, the Bijur DS at 15 MPa and 25 ml/min — cover powered transfer where compressed air is absent. Hand-operated units move grease by lever, slowly, with nothing to power at all.
Where a unit also sits on the air, electric or bucket-pump pages for its drive class, the table says so; this page holds the transfer-duty view.
Transfer Duty by Drive
| Drive | Unit | Stated spec |
|---|---|---|
| Air | SM Type SUREMATIC, Sure 881 | 18:1 ratio, 2-liter, 8 cc/stroke |
| Electric | DZG electric, Y6020, Bijur DS | DZG 25 MPa 6 ml/min 220/380V; DS 15 MPa 25 ml/min |
| Bucket-mount electric | 5-gallon bucket pump, Bucket pump 120V/12V/18V | Mounted on the pail they empty |
| Manual | Hand-operated transfer pump | Lever drive, no power needed |
| High-viscosity general | 25 kg pneumatic grease pump | Pneumatic, high-viscosity class |

Grease Transfer Pump FAQ
Transfer pump or lubrication pump — what is the difference?
Duty, not hardware. A transfer pump empties containers: drum to reservoir, bucket to machine tank. A lubrication pump feeds measured grease to bearings through lines and meter units. Several pumps here do both jobs — the DZG and DS run at pressures that serve progressive lines — but they are cataloged for transfer because that is the first question buyers ask of them.
Why does the SUREMATIC quote a ratio?
The 18:1 is air-to-grease pressure multiplication: 100 psi of air in, roughly 1800 psi of grease out — the ratio stated in the title of the SM Type unit. That is what lets an air motor push NLGI-2 grease through a hose stiff with cold, at 8 cc per stroke from its 2-liter container.
What does 6 ml/min versus 25 ml/min mean in practice?
Filling speed against line duty. The DZG’s 6 ml/min at 25 MPa is a high-pressure, low-volume profile — it can push through resistance. The DS at 15 MPa and 25 ml/min moves roughly four times the volume per minute at lower pressure. Refilling a reservoir through an open port favors volume; pushing through a long hose favors pressure.
Is a bucket-mount pump a real transfer pump?
Yes — it is transfer in its most direct form. The 5-gallon units and the 120V/12V/18V bucket pump thread onto the pail the grease ships in, so the container is the reservoir. There is no decanting, no drum tapping; the pump lifts grease straight from the original package.
Which drive should a workshop without compressed air choose?
Electric or hand. The DZG, Y6020 and bucket pumps run on mains or battery voltages; the hand-operated lever pump needs nothing but arm effort and moves grease at a pace that suits occasional machine-top-ups. Send the grease grade and container size through the contact page and the return matches a unit to both.
