12V Water Pump 2335548 4812126685 High Pressure Pump For Road Roller Now In Stock

Our parts workshop has added a stock item aimed squarely at asphalt compaction crews: the 12V high pressure water pump covering reference numbers 2335548 and 4812126685. It is a direct bolt-on replacement for the water spray circuit on road rollers, and it ships from stock in single units, so a failed pump no longer means the roller sits out a shift while a dealer order is processed.

The spray pump is small, cheap and easy to overlook until it fails. When output drops, the drum stops being fully wetted. Bitumen starts to pick up on the steel, the operator has to stop and scrape, and the rolling pattern that the compaction curve depends on is broken. On a tight program that lost time never comes back, and on a thin mat it often shows up later as a patchy, uneven surface.

This pump is built to hold steady pressure at the spray bar with several nozzles open at once, so coverage stays even from the first pass to the last, at normal rolling speed.

• Direct replacement fit. Mounting footprint, inlet and outlet ports and connector type match the original pump, so the swap is a workshop task rather than a fabrication job.
• Self-priming diaphragm design. No mechanical seal to leak water into the motor housing, and the pump tolerates running dry briefly during tank changes.
• Low current draw. The 12V motor runs from the machine's standard electrical system without stressing the battery over a long shift.
• No brand locked pricing. Supplied as an OEM replacement in neutral packing, so buyers are not tied to one dealer network or one price schedule.

Roller water circuits vary more than buyers expect. Please send three lines with your enquiry: the machine model and serial range, the reference number stamped on the failed pump, and the connector and port size on the existing unit. With those three details we confirm the matching configuration, current stock and freight to your nearest port.

For contractors running a mixed fleet, we can hold a stock allocation and ship on a call-off basis, which keeps spares available without tying up storage space on site.

The pump is available now in single units and in fleet quantities, with volume pricing from fifty pieces. For flow curves, dimensional drawings or a quotation against your machine list, contact our parts desk and quote the reference numbers above.
