Subaru’s PKV101 Centrifugal Pump uses heavy-duty design features yet keeps size and weight in check, making it one of the smallest, most compact pumps on the market. Although it weighs only 11.7 pounds, the PKV101 maintains many of the quality components found throughout the larger models in the Subaru pump line. The design includes a ceramic carbon mechanical seal, which self-lubricates and prevents the wear caused by repeated use that can lead to leaks, and the impeller and pump housing of the self-priming PKV101 are made with solid, heavy-duty aluminum.
