Auto Grease Pump
IsoHiTech auto grease pumps supply metered grease to progressive blocks, injectors, and direct lines—replacing manual gun service on machine tools, mobile equipment, and heavy industry. This hub compares electric cabinet pumps, mobile DC units, barrel transfer pumps, and multi-point DDB skids on the sections below.
Start at the grease pump hub for types and troubleshooting, or pair any pump here with progressive blocks, timers, and distribution tubing.
Isohitech Lubrication Auto Grease Pump
With 20 years in centralized lubrication, IsoHiTech covers single-line, dual-line, progressive, oil mist, and injector architectures—matched to the auto grease pump on this page.
How an Auto Grease Pump Works in a Complete System
An automatic grease pump is only the pressure source. A field-ready auto grease system includes:
- Reservoir + pump element — builds line pressure to overcome hose friction and cold grease stiffness
- Metering — progressive divider or injector splits total flow into ml per point per cycle
- Control — timer or PLC: lubricate interval + pause interval + low-level input
- Distribution — hose, fittings, optional filter
During lubricate, the pump runs until pressure reaches setpoint or time limit. During pause, progressive pistons reset and injectors recharge. Repeating on schedule keeps bearings in a fresh grease film without over-packing seals.
Pump Model Selection Matrix
| Model (on this page) | Best application | Reservoir | Pressure / flow | Outlets |
|---|---|---|---|---|
| DZGK-L | Machine tool cabinet, enclosed skids | 4–8 kg | ~25 MPa; #68 oil to NLGI #2 | 1–4 |
| DZG type | Plant central supply, larger tanks | 2–100 kg | ~25 MPa | Multi-outlet options |
| FS | Mobile equipment, IP67 duty | 4–8 kg | 16–30 MPa; ~2.9 ml/outlet | 1–3 |
| SK-505 | Compact DC, single line | 1 L | 8 MPa; ~13 ml/min class | 1 |
| Y6020 | Barrel transfer / workshop | 20–30 L drum | ~0.6 L/min; NLGI to #3 | Transfer gun line |
| BS-B | Large plant bulk tank | 60–100 kg | ~40 MPa; 750 W | Header feed |
| DDB multi-point | Pre-engineered injector manifold skid | 7–23 L | 10 MPa; per-injector dose | 10–36 injectors |
7-Step Sizing Worksheet
- Count grease points and group by duty (high-load pin vs light cover)
- Define ml per point per cycle from OEM or trial—sum for total demand
- Choose architecture — progressive for 8+ points; single injectors for small zones
- Pick pump flow — rated output ≥ total metered demand + 25–30% margin
- Match NLGI — pump spec must list your grease grade (#0–#3)
- Power — 220 V cabinet vs 12/24 VDC mobile vs pneumatic barrel
- Control — integrate level switch, pressure switch, and fault relay to machine PLC where required
Progressive vs Injector Pairing
| Method | When to pair with auto grease pump | Pump notes |
|---|---|---|
| Progressive blocks | 8–100 points, proof-of-sequence needed | FS, DZGK-L, BS-B feed header; one cycle pin proves delivery |
| Single-line injectors | 4–40 points, individual dose tuning | DDB skid or pump + SL32/SL1 injectors; pause for recharge |
| Direct line (SK-505) | 1–3 points, space limited | Verify stroke volume vs bearing cavity |
Environment & Reliability
- IP65/IP67 pumps (FS class) for outdoor mobile and washdown areas
- Cold climate — softer NLGI #1 or #0; optional reservoir heater on cabinet pumps
- Dusty mines — breather and filler cap management; line filter on long headers
- Food-adjacent — confirm H1 grease compatibility with pump seals
Sample BOM — 24-Point CNC Cell
- 1× DZGK-L 4 kg, 220 V, 2 pump outlets
- 1× primary progressive block + 2× secondary slices (8+8+8 outlets)
- 1× digital timer — 90 s lubricate / 4 h pause (example only; tune to OEM)
- 11×6 mm header hose, 9×4 mm drops, Pt 1/8 fittings
- Cycle indicator switch to machine alarm input
Troubleshooting Auto Grease Pumps
| Symptom | Cause | Fix |
|---|---|---|
| Pump runs, no pressure | Empty tank, air lock, check valve stuck | Fill; bleed at highest point; inspect element |
| Pressure high, no flow at points | Blocked progressive section, frozen grease | Do not plug progressive ports randomly; rebuild block |
| Grease too thin at points | Over-cycle timer, wrong injector setting | Reduce lubricate time; recalculate cc/cycle |
| Pump cycles too often | Leak downstream, stuck open injector | Pressure test segments; replace faulty injector |
| DC pump nuisance trips | Low voltage, long cable run | Verify 24 V at pump; upsize wire |
Manual Backup
Keep a hand grease pump on site for commissioning bleed and emergency service—manual pumps are not substitutes for automatic scheduling but reduce downtime when a zone is isolated for repair.
