Duro K255 Piston Pump Manual Review

You regularly pump very thick oils (SAE 140 gear oil, molasses-like fluids) or need all-day continuous use – step up to a lever-action drum pump with Viton seals.

The Duro K255 does exactly what the manual promises – no more, no less. It’s not industrial grade, but for the price, it’s dependable, repairable, and widely available. Keep a spare seal kit on hand, and it will last for years. Note: This review is based on the Duro K255 manual version 2.1 (2019) and aggregated user feedback from automotive forums and Amazon/Ebay reviews. Always verify fluid compatibility with your specific fluid’s SDS before use. duro k255 piston pump manual
