Isohitech’s Grease Pumps
Grease pumps move NLGI grease from pails, cartridges, or built-in reservoirs to bearings, pins, and centralized headers. Unlike oil, grease stays in place on vertical and exposed points—ideal for construction, mining, machine tools, and fleet maintenance bays.

Benefits of Grease Pump Systems
A key benefit of grease pump systems is that they help your equipment last longer. These systems cut down on wear and tear by keeping machinery well-lubricated. This matters a lot for industries such as construction, mining, and manufacturing. In these fields, equipment faces heavy loads and tough conditions. Isohitech’s grease pumps provide the right amount of grease at the right times. This helps avoid under- or over-lubrication. Such issues can cause early failures. Using our grease pump systems regularly helps your machinery last longer. This means fewer replacements and more savings over time.
Grease pump systems not only extend equipment life but also improve operational efficiency. Lubrication cuts down friction between moving parts. This leads to smoother operation and may lower energy use. Automated systems, like Isohitech’s pneumatic and electric grease pumps, prove this point well. They deliver exact amounts of grease independently without needing manual help. These systems lower friction and wear. This helps keep equipment running well. As a result, downtime is less, and productivity goes up. Isohitech’s grease pump systems improve efficiency. They work well for small workshops and large industrial facilities.
Investing in a grease pump system can save your business time and money. These systems lower maintenance costs by extending equipment life and reducing repairs. Automated options like Isohitech’s electric and pneumatic pumps cut down on time and labor costs for manual lubrication. Our advanced systems have programmable settings and remote monitoring. This helps you optimize lubrication intervals and catch potential issues early. As a result, you can reduce downtime and lower maintenance costs. Choosing Isohitech’s grease pump systems is a smart investment for your equipment and your business’s future.
Grease pump systems also offer important safety and precision benefits. Manual lubrication can be messy and risky. This is especially true in industries that use heavy machinery. Isohitech’s automated grease pumps help keep workers safe. They cut down on the need to reach dangerous or hard-to-access spots. Our systems let you control exactly how much grease is dispensed. This way, each part gets the right amount of lubrication. This precision prevents problems like over-greasing, which attracts dirt and contaminants. It also avoids under-greasing, which can cause more wear. Isohitech’s grease pump systems make your workspace safer, cleaner, and more efficient.

Understanding Air Ratio (50:1 / 55:1)
Pneumatic barrel pumps multiply air line pressure into grease outlet pressure. Example: 0.6 MPa (6 bar) shop air × 50 ≈ 30 MPa at the gun—enough for long hose runs and stiff NLGI #2. Higher ratio = higher outlet pressure at same air input, not more volume per stroke. Size air supply for duty cycle (continuous transfer vs occasional gun shots). Install water separator and regulator upstream; contaminated air damages pump air motor seals.

Decision Tree — Which Pump Type?
- How many points? 1–3 → hand or gun; 8+ automatic → electric + metering
- Power available? No electric at drum → air barrel; mobile machine → 12/24 V; fixed plant → 220/380 V
- Schedule? On-demand only → air or hand; timed cycles → electric + timer
- Architecture? Progressive/injector → electric steady fill; dual-line → BSB class (not progressive)
- NLGI? #3 or cold climate → check Y6020 / BM-B; #000–#2 → most DZGK / air duty
Manual vs Air vs Electric — When to Use Which
| Factor | Manual | Air | Electric auto |
|---|---|---|---|
| Point count | 1–few | Transfer + gun | 8–1000+ with metering |
| Schedule | Operator driven | On demand | Timer / PLC |
| Pressure class | ~15 MPa hand | 30–55 MPa ratio pump | 8–40 MPa |
| NLGI | #0–#2 typical | #000–#2 common; some #3 | #000–#3 model dependent |
| Environment | Any | Needs clean air supply | IP65/IP67 on mobile FS class |
Building a Centralized Grease System
- Pump — match reservoir, pressure, outlets to architecture
- Metering — progressive blocks or injectors
- Control — timer, level switch, pressure switch
- Distribution — pipe, hose, fittings
- Commission — bleed, verify cycle pin or injector click, document intervals
Pressure & NLGI Quick Reference
| Application | Typical pressure | NLGI |
|---|---|---|
| Machine tool progressive | 16–25 MPa | #1–#2 |
| Mobile FS progressive | 16–30 MPa | #0–#2 |
| Barrel air transfer | 30–55 MPa at gun | #000–#2 |
| Dual-line mining header | Up to ~40 MPa | #1–#2 EP |
Sample BOM — Workshop Barrel + Machine Feed
- 55:1 air barrel pump on 200 L drum + hose reel gun for PM
- Separate 220 V DZGK-P 4 L on machine with progressive block (8 points)
- Shared NLGI #2 EP grease—do not mix thickeners in same progressive circuit
Sample BOM — Fleet Maintenance Bay (Air Only)
- 50:1 pump on 20 L pail + 15 m hose reel + control handle gun
- Second 55:1 on 200 L drum for high-volume excavator service
- Wall-mounted regulator 0.5–0.7 MPa; FRL unit with auto drain
- Color-code guns: EP #2 for chassis, separate cartridge for open gear if required
Sample BOM — Plant Dual-Line Header
- BSB / BM-B class pump on 60–100 kg tank
- ZVB dual-line valves (not progressive)—alternate line pressurization
- Main 15×2 mm lines, branch to pin blocks; pressure switch on each line end

Troubleshooting (All Types)
| Symptom | Likely type | Fix |
|---|---|---|
| Air pump stalls, no grease | Pneumatic | Check ratio pump frozen grease; warm drum; verify air pressure and lubricator |
| Gun pressure weak at distance | Air / hand | Upsize hose ID; reduce length; increase air input; lower NLGI grade |
| Electric runs, no build | Electric | Bleed air; check check valve; verify level switch not latched |
| Follower plate gaps in drum | Barrel air | Replace follower seal; keep drum upright; avoid water in grease |
| Progressive never completes | Auto system | Find blocked outlet—do not plug other progressive ports to compensate |
Pairing Metering — Quick Links
- Progressive: DZGK-P, DZG, FS → M2500, DJF3000
- Injectors: multiply skids → SL32
- Dual-line: BSB → ZVB (dual-line architecture)
Common Mistakes
- Using air pump as continuous automatic header feed without timer and relief
- Undersizing pump for cold grease—stiff NLGI #2 in winter needs larger motor or #1 grade
- Mixing oil into grease circuit—contaminates progressive pistons
- Confusing dual-line pumps/blocks with progressive architecture
Maintenance Checklist
- Weekly: reservoir level, visible leaks, listen for bypass
- Monthly: follower plate/barrel seal on drum pumps; filter on air line
- Quarterly: pump element inspection; progressive block cycle pin movement
- Annual: replace hoses showing chafe; pressure test after block rebuild

Frequently Asked Questions
A device that pressurizes and dispenses NLGI grease from a reservoir to fittings, guns, or automatic metering devices.
Manual hand pumps, pneumatic barrel pumps (5:1–55:1), electric cabinet and mobile pumps, and high-flow dual-line plant pumps.
No—use an oil pump for fluid lubricants. Grease pumps are designed for semi-solid NLGI products.
Electric pumps like the DZGK-P (24V DC) are ideal for tight areas (e.g., automotive shops). No air supply needed.
We have many pumps like DZGK-L and Y6020 Grease Pump support up to 200 points. Pair with our BSB Dual Line Pump (1,000-point capacity) for larger systems.
Yes! Our DZGK-L model equipped with IP65K protection level for mining/chemical industries.
Yes – contact us for customized pricing on orders of 5+ units.
Pneumatic 50:1 or 55:1 barrel pump with follower plate and high-pressure hose—see 55 gal product on this page.
Electric DZGK-P / DZG or FS class paired with progressive blocks or injectors—not manual gun alone.
Typically #000–#2 on most electric progressive systems; barrel and Y6020 models often accept to #3.
Match pump max pressure to hose, block, and fitting class—common progressive circuits use 16–30 MPa; dual-line may need 40 MPa.
A gun is manual single-shot; a pump feeds multiple points automatically or supplies a reel gun continuously from barrel.
See lubrication grease pump and auto grease pump hubs.
Yes—send point count, NLGI, voltage, and environment for pump + metering BOM.
Ratio sets outlet pressure vs air input—55:1 reaches higher grease pressure for long hoses and #2 grease; 5:1 suits lower-pressure transfer. Volume per stroke depends on pump displacement, not ratio alone.
Large plant headers, long pipe runs, or mining class systems often use dual-line (BSB pump + ZVB)—different reversal logic than progressive blocks. Do not mix architectures on one header.
