Small Grease Pumps
“Small” in grease pumps means three measurable things: a compact reservoir — 0.4 to about 2 liters — a metered flow counted in milliliters per minute, and a mounting scope of one machine or one vehicle rather than a line of them. The catalog here holds to that definition, and the table below states the numbers so the word never has to argue for itself.
The families present: DZG-class electrics at 25 MPa and 6 ml/min, the EGM-50TH at 10/20 MPa on DC24V, IHI SK-505BM units with 0.4-1 L reservoirs, Bijur BM-B, CSK and DS machine-mount units, P203-class and LHL P-102/107/202/207 replacements, and the Sure 881 portable air pump.
Where a unit also belongs to a bigger family — the electric-grease or 24V pages, for example — the closing table cross-references it rather than pretending this page is its only home.
Where a Small Pump Earns Its Place
| Mounting or duty | Unit | Stated spec |
|---|---|---|
| Vehicle 24V feed | DC24V-B, DC24V electric | 24V vehicle-mount class |
| Machine-mount electric | BMB / BM-B, CSK, DS | Bijur Delimon compact electrics |
| Higher-pressure small | DZG (AC380V) | 25 MPa, 6 ml/min |
| Injection lubrication | EGM-50TH | 10/20 MPa, DC24V |
| Compact electric, IHI class | SK-505BM | 0.4-1 L reservoir range |
| Drop-in replacements | P203, LHL P-102/107/202/207 | Named-model replacement classes |
| Portable air | Sure 881 | Air-driven, portable |

Small Grease Pump FAQ
What actually qualifies a grease pump as small?
This page applies a working definition, not an industry standard: reservoir up to about 2 liters, metered delivery in milliliters per minute, and scope of one machine or vehicle. The DZG at 6 ml/min and 25 MPa shows why reservoir alone is a poor yardstick — small flow can still mean serious pressure. Judge by the stated numbers in the table, which come straight from product titles.
Which unit suits a 24V vehicle installation?
The DC24V-B unit and the DC24V electric pump are the stated 24V classes, built for chassis lubrication where the machine is the power source. Where injection lubrication is the job rather than chassis rounds, the EGM-50TH at 10/20 MPa on DC24V is the specialist — same voltage class, different duty.
Can a small pump feed a progressive system?
Yes, with divider blocks downstream — that is exactly the P203-class role, where a compact pump feeds a block that splits each stroke across several points. The pump stays small; the system does not have to. What matters is that pump output volume and block cycle volume match, which the spec sheets on each product page state.
Is a small pump enough for a workshop instead of a bucket pump?
For measured, repeatable feeding of a few machines, yes — and the Sure 881 portable air unit is the flexible option, moving between stations where plant air is available. A bucket pump still wins for high-volume bearing packing. The failure mode to avoid is buying small for economy and running it at 100% duty cycle; size for the point count, not the budget.
Can you size one to my machine?
Send the machine and point count through the contact page. The answer comes back with reservoir size, voltage class and expected refill interval — the three numbers that decide whether a small pump is right or whether the duty has outgrown the class.
