P215 Multi-Line Grease Pump — Up to 15 Adjustable Outlets
The P215 grease pump is an electric multi-line lubricator for large centralized plants that need independent outlet dosing without a single progressive divider chain. Up to 15 pump elements each deliver a fixed volume per stroke; output per element is adjustable from 25% to 100%. Maximum working pressure 350 bar (35 MPa).
Drive: 380 V three-phase motor with reducer (confirm Hz and mounting on order). Lubricants: greases to NLGI grade 2 (grade 3 on request); mineral oils to 20 mm²/s. Integrates with level switch on reservoir and optional fill port. For progressive-only architectures, compare 20703 automatic grease pump + metering unit; for mobile DC, see FS series.

Adjustable Pump Elements
Each element is a modular piston cartridge—replace or re-stroke one outlet without rebuilding the full pump. Set dose to match bearing size, pipe length, and required grams per cycle. On multi-outlet systems, document each element’s % stroke and K6/K7 code in the plant lubrication chart.
P215 vs Progressive Divider Architecture
P215 multi-line: each outlet pumps directly (or via short line) to a point—one stalled outlet does not block others. Progressive divider (M2500 / 3000 / 2000): outlets fire in sequence; blocked piston stops the chain. Choose P215 when lines are long, consumption varies per point, or you need 15 unequal doses from one electric drive.
Design Features
- Multi-line: 1–15 outlets on one gearbox—scale plant without multiple pump skids
- Electric drive: consistent cadence vs manual pumps on high-consumption machines
- Fill connection: optional quick-fill for NLGI #2 from barrel pump (Y6020 class)
- Level switch: empty-tank signal to PLC or alarm horn
Applications
- Steel & forging: eccentric presses, rolling mills—high grease demand
- Material handling: cranes, stackers, long conveyor galleries
- Construction & mining: crushers, screens (pair with hose protection on exposed lines)
- Large progressive hybrids: P215 feeds main headers; sub-manifolds use divider blocks
Benefits & Sizing Notes
- Durability: industrial gearbox and hardened pump elements for 350 bar duty
- Efficiency: fewer manual greasing rounds; PM intervals align with production shifts
- Flexibility: mix K6 and K7 elements on one pump for small vs large bearings
When sizing, sum cm³/stroke × cycles/hour per outlet and verify reservoir kg/day against tank capacity. Protect pump with inline filter on dirty fill practices.

When to Specify P215 Multi-Line
The P215 grease pump fits plants where each lubrication point needs its own dose and schedule tolerance—not a single progressive chain that stops when one piston blocks. Typical triggers:
- Unequal consumption — large press bearings vs small guide ways on one machine line
- Long primary lines — outlet pumps grease into a header; sub-lines tee to points without serial divider dependency
- High pressure headroom — 350 bar class for stiff NLGI #2 in cold plants or long small-bore tube runs
- Electric cadence — 380 V drive for continuous-duty steel, mining, and material-handling shifts
If every point can share one progressive sequence with similar gram doses, 20703 + metering unit or FS progressive is often simpler. P215 wins when you need up to 15 independent strokes from one gearbox.
P215 vs Other Grease Pump Families
| Pump | Architecture | Pressure | Outlets | Best fit |
|---|---|---|---|---|
| P215 (this page) | Multi-line direct elements | 350 bar | 1–15 adjustable | Steel, forging, cranes, large unequal doses |
| 20703 automatic | Pump + progressive divider | 25 MPa | Divider outlets | Cabinet / mobile centralized progressive |
| 20703 motor pump | Timer + progressive | 25 MPa | Divider outlets | DC/AC machine OEM with timer |
| FS series | Progressive on skid | 25 MPa | Divider chain | Construction equipment DC |
| P215 + divider hybrid | P215 feeds M2500/3000/2000 manifold | 350 bar → divider rated | Combined | Very large plants, zone manifolds |
Sizing K6 and K7 Elements
Each stroke delivers 0.16 cm³ (K6) or 0.23 cm³ (K7) at 100% setting. At 50% stroke, halve those values. Example: K7 at 75% → 0.23 × 0.75 ≈ 0.17 cm³ per cycle.
- List each bearing with target grams per day from OEM chart.
- Convert to cm³ (grease density ≈ 0.9–1.0 g/cm³ for NLGI #2).
- Divide daily volume by planned cycles per day → cm³ per stroke required.
- Pick K6 or K7 and set 25–100% stroke to match—document on lubrication plate.
- Sum all outlets × cycles/hour → check reservoir kg/day and refill interval.
Mix K6 on small points and K7 on high-consumption bearings on the same pump body—order spare elements by outlet index on your BOM.
380 V Motor, Reducer & Control
P215 runs on 380 V three-phase motor through a lubrication pump reducer (ratio per outlet count and grease grade). On inquiry, confirm:
- Mains 380 V / 50 Hz or 60 Hz and motor flange / foot mount
- Run signal from PLC, time relay, or machine interlock (dry contact)
- Level switch — stop pump on empty tank to protect elements from dry stroke
- Fill port — quick-fill from barrel pump during shutdown
Do not overspeed pump on cold NLGI #3 without factory approval—viscosity spikes can overload reducer and motor thermal limit.
Installation & Commissioning
- Mount pump and 16–25 kg aluminum reservoir rigid on skid; align motor coupling per drawing.
- Plumb each outlet with rated 350 bar hose or lubrication tubing; use compression fittings or flange per line size.
- Install inline filter on fill path if drum transfer is dirty.
- Set each element stroke per chart; lock adjuster screw and mark position.
- Run pump; bleed air at highest fittings until fresh grease extrudes.
- Verify pressure at gauge port; log element index, K6/K7, and % stroke on machine nameplate.
Hybrid: P215 Feeding Progressive Dividers
On very large plants, one P215 outlet can supply a progressive manifold (grease manifold block or page-related M2500 / 3000 / 2000) while other outlets feed direct injectors or bearings. Design rules:
- Divider inlet pressure must stay within divider catalog rating—may be below 350 bar; use relief or series restriction if needed.
- Size P215 outlet stroke so divider receives enough volume per cycle for all downstream sections.
- Alarm on divider cycle switch still applies—P215 does not replace blockage monitoring on progressive legs.
Maintenance Schedule
- Each shift — reservoir level, audible leaks at element glands, motor temperature normal.
- Weekly — spot-check farthest point for fresh grease; confirm PLC run hours match plan.
- Monthly — inspect fill strainer, clean breather, verify stroke marks not drifted.
- Annual — replace worn element seals, change gearbox oil per reducer manual, pressure-test relief path.
Troubleshooting
| Symptom | Likely cause | Action |
|---|---|---|
| One outlet no flow | Element stuck, line blocked, stroke at 0% | Replace element; clear line; reset stroke |
| All outlets weak | Empty tank, suction air leak, wrong NLGI | Refill; fix cover seal; use approved grade |
| High motor amps | Cold #3 grease, reducer oil low, mechanical bind | Warm grease; service reducer; inspect coupling |
| Grease leaks at adjuster | Worn plunger seal | Replace element cartridge |
| Pressure below 350 bar | Open bypass, relief stuck, severe leak downstream | Isolate outlet; test element; repair fitting |
