Aftermarket P215 Multi-Line Pump Assembly
This page describes an aftermarket pump assembly for Lincoln P215 multi-line lubrication systems. The unit delivers grease or oil through up to fifteen independently adjustable outlets, each driven by its own radial piston element. Lincoln is a trademark of its respective owner. This is an aftermarket pump assembly, not manufactured, sponsored, or endorsed by Lincoln. P215 designations are for cross-reference identification only.
The pump is built for centralized lubrication duties where a single reservoir and drive feed multiple lube points directly. Each outlet can be tuned from 25 to 100 percent of its rated stroke, and all elements run from one common eccentric shaft. Buyers should review the full nameplate code before assuming a one-for-one replacement with an older installed base.
How a Multi-Line Pump Works
A multi-line pump differs from a progressive system because every outlet is its own metering channel. One rotating eccentric drives all radial piston elements, but each piston assembly can be adjusted independently while the pump is stopped. The result is a set of discrete, timed outputs that do not depend on downstream divider sequencing.
An integrated stirring paddle rotates inside the reservoir and homogenizes the grease while helping vent trapped air. The paddle is especially useful with stiff greases up to NLGI 2, where air pockets can otherwise starve the piston inlets. For oils with viscosity at or above 20 mm2/s, the stirrer continues to reduce settling and maintain a steady feed to each element.
Each outlet must be protected by a pressure-limiting valve installed at the element outlet. The valve prevents overpressure at the bearing point if a line becomes blocked or a bearing is overgreased. The pump control system does not include per-outlet relief, so this external valve is a required part of any installation.
Element Sizes and Output
Three piston diameters are available: K5, K6, and K7. The declared output per stroke is approximately 0.11 cm3 for K5, 0.16 cm3 for K6, and 0.23 cm3 for K7. Factory default output for every element is set to minimum, and adjustment should occur only after commissioning and line priming.
| Piston size | Output per stroke | Notes |
| K5 (5 mm) | 0.11 cm3 | Smallest adjustable volume per cycle |
| K6 (6 mm) | 0.16 cm3 | Common mid-range choice for general bearings |
| K7 (7 mm) | 0.23 cm3 | Largest volume, useful for larger housings |
The pump accepts from 1 to 15 radial piston elements. Any unused outlet positions are blanked at the factory. Confirm the exact element count and piston size against the old pump nameplate before ordering a replacement.
Reservoirs, Drives, and Monitoring
Reservoir options include 2 L, 4 L, and 8 L plastic tanks plus 10 L, 30 L, and 100 L steel tanks. A capacitive level sensor is available for steel reservoirs. An optional ultrasonic level sensor carries an IP67 rating and works with both plastic and steel tanks.
Gear ratios are 7:1, 49:1, 100:1, and 490:1. Drive speed must remain under 28 rpm at the pump input. Motor power is 0.18 or 0.21 kW at the 100:1 gearbox, and 0.25 or 0.29 kW at the 49:1 ratio. Motor voltages are 380 to 420 V 50 Hz, 440 to 480 V 60 Hz, or 500 V 50 Hz.
Monitoring options include the ultrasonic level sensor, a reed switch, or a capacitive sensor for steel reservoirs. Optional heating elements support cold-weather operation. ATEX variants are available for hazardous areas, and the pump body carries CE and UKCA marking with IP55 protection.

Reading the Pump Nameplate Code
The model code breaks into clear segments. A teaching example is P215-M100-30XYBU-5K6-380-420. M100 indicates an AC flange motor with a 100:1 ratio. 30XYBU means a 30 L steel reservoir with an ultrasonic level sensor. 5K6 means five elements with 6 mm pistons. 380-420 is the multi-range 380 to 420 V motor.
Before ordering, copy the full code from the existing pump. The reservoir size, ratio, element count, piston size, and voltage all live in that string. Ordering by generic model number alone often leads to a mismatch in mounting or output.
What to Confirm Before Ordering
Mounting must be vertical, within 5 degrees of tilt. Confirm the outlet connection as G 1/4 BSPP with up to 15 outlets. The max operating pressure is 350 bar, or 5,076 psi, and the operating temperature range is -25 to +70 C.
Confirm the grease consistency before selecting a reservoir stirrer and level sensor. Greases up to NLGI 2 are standard, and NLGI 3 is available on request. Oils should have a viscosity of 20 mm2/s or higher. Confirm the required gear ratio and motor voltage from the existing installation, especially if the pump feeds a mix of high and low drag points.
This pump can work as a central pump feeding progressive metering devices, or as a standalone multi-line direct supply. The choice affects how each outlet is set and whether downstream dividers are included. Review the progressive lubrication systems guide for divider-fed layouts.

Frequently Asked Questions
How many elements do I need?
Count the number of lube points that need independent volume control. Each point gets its own element, up to fifteen.
Should I choose K5, K6, or K7 pistons?
Choose K5 for small volumes, K6 for general bearings, and K7 for larger housings. Output per stroke is declared at 0.11, 0.16, and 0.23 cm3.
What does the stirring paddle actually do?
The paddle homogenizes grease inside the reservoir and helps vent trapped air. This keeps piston inlets fed with consistent material during each stroke.
Is a pressure-limiting valve required on every outlet?
Yes, a pressure-limiting valve is required at each element outlet. The pump has no internal per-outlet relief.
Can it run NLGI 2 grease in cold weather?
Optional heating elements support cold-weather operation. The base operating temperature range is -25 to +70 C.
What is the minimum oil viscosity for this pump?
The declared minimum oil viscosity is 20 mm2/s. Thinner oils may not maintain a consistent inlet feed.
Will it replace an existing P215 directly?
It may replace an existing P215 if the full nameplate code matches. Confirm reservoir size, ratio, element count, piston size, and voltage.
Which reservoir should I choose?
Choose plastic 2 L, 4 L, or 8 L tanks, or steel 10 L, 30 L, or 100 L for larger systems. Steel reservoirs are required for capacitive level sensing.
Does it feed progressive dividers?
Yes, it can act as a central pump feeding progressive metering devices downstream. It also works as a standalone multi-line direct supply.
