What the P203 Replacement Is
The P203 grease pump replacement is an aftermarket-compatible supply pump for single-line progressive lubrication systems. It sits on the machine reservoir and pushes grease to progressive distributor blocks on a timed cycle. IsoHiTech supplies aftermarket-compatible components. Brand names are used for compatibility reference only. IsoHiTech is not an authorized OEM dealer.
The unit covers the common P203 configurations: 2 L, 4 L, and 8 L reservoirs, three supply voltages, and a timer-driven or timer-plus-override control scheme. This page is the ordering reference: model code, compatibility, voltage, timer, and reservoir. Operation and troubleshooting live on the P203 grease pump guide.

| Maximum operating pressure | 350 bar (5,000 PSI) |
| Lubricant | grease up to NLGI class 2; oil 40 to 1,500 centistokes |
| Pump element | 1 x K6, expandable to 3 elements |
| Outlets | up to 3 |
| Electrical connection | left-side rectangular industrial connector; a wiring diagram ships with the pump |
| Timer | adjustable 1-60 minute intervals; manual override option on 24V timer versions |

The pump ships with reservoir, element, and timer where configured. Grease, mounting bracket, and cables are not included.
Reading the P203 Model Code
The code on the nameplate encodes the configuration, and the segments read in a fixed order. The first digit after P203- is the reservoir volume in liters. The next segment is the voltage: -24- marks a 24V DC unit. The K6 segment counts pump elements: 1K6 is one element, expandable to three. The remaining segments set the variant and revision, so confirm the complete code from the nameplate before ordering rather than guessing from the first digits.
- P203-2XN-1K6-24-1A1-10-V10: 2 L reservoir, 24V DC, integrated timer.
- P203-4XN-1K6-24-2A1.10-V10: 4 L reservoir, 24V DC, timer plus manual override.
- P203-8XNBO-600-AC-D1000000-V10A: 8 L closed reservoir, 110-260V AC, stirring paddle.
How the Pump Feeds a Progressive System
In a progressive system the pump does not meter each point itself. It feeds a network of progressive distributor blocks that cycle grease point by point as pressure rises, so the pump only builds pressure, holds it, and refills the line on schedule. See progressive lubrication systems for the full layout and how a distributor block cycles for the metering side. The 350 bar maximum leaves the blocks enough headroom to shift even with colder grease in the line.
Choosing Reservoir, Voltage, and Timer
The 2 L and 4 L reservoirs suit compact machines where the pump hangs on a small frame or inside a cramped enclosure. The 8 L closed reservoir, with its stirring paddle, suits high-consumption points that would empty a small reservoir too quickly. Match the voltage to the machine supply: 12V DC on mobile equipment, 24V DC on most industrial control circuits, and 230V AC where mains power is on the machine. The 8 L closed AC version accepts 110-260V AC, which absorbs regional mains differences without an added transformer. The timer sets the pause between cycles anywhere in a 1-60 minute range, and on 24V timer versions a manual override with illuminated button is optional for manual greasing rounds. Machines that are not progressive-system installations may be better served by a unit from the electric grease pump range.
Compatibility and Ordering Checklist
Work through five checks before ordering a replacement:
- Element count: match the installed unit, whether one K6 element or expanded to three.
- Outlet count: match the number of feed lines, up to 3 outlets.
- Maximum pressure: confirm the system stays within 350 bar (5,000 PSI).
- Lubricant: grease up to NLGI class 2, or oil from 40 to 1,500 centistokes.
- Supply voltage: 12V DC, 24V DC, or 230V AC as fitted on the machine.
Confirm the complete model code from the nameplate, not from memory. Grease, mounting bracket, and cables are not included with the pump. Ask for a configured quote through the contact page, and see the grease pump range for the wider family.
Frequently Asked Questions
What is a P203 grease pump replacement?
It is an aftermarket-compatible supply pump for single-line progressive lubrication systems. It replaces installed P203 units in the same mounting and connection pattern.
How do I read the P203 model code?
The first digit after P203- is reservoir liters, and -24- marks 24V DC. The K6 segment counts elements; confirm the complete code from the nameplate before ordering.
Will it run my existing progressive system?
Match element count, outlet count, the 350 bar maximum, lubricant, and supply voltage. Grease up to NLGI 2 and oil from 40 to 1,500 centistokes are within range.
What voltage versions exist?
Versions exist for 12V DC, 24V DC, and 230V AC supplies. The 8 L closed-reservoir AC version accepts a 110-260V AC input.
What electrical connection does it use?
It uses a left-side rectangular industrial connector, a common solenoid-valve connector pattern. A wiring diagram ships with the pump; no pinout is published.
How is the timer set?
The timer adjusts across 1-60 minute intervals for the pause between cycles. On 24V timer versions a manual override with illuminated button is optional.
Which reservoir size should I choose?
The 2 L and 4 L reservoirs suit compact machines with modest consumption. Choose the 8 L closed reservoir with stirring paddle for high-consumption points.
Is this a genuine SKF Lincoln unit?
No. It is an aftermarket-compatible replacement supplied by IsoHiTech for SKF Lincoln P203 configurations, built to match mounting and connection patterns.
What is included with the pump?
The pump ships with reservoir, element, and timer where configured. Grease, mounting bracket, and cables are not included; request the full bill through our contact page.
