Thelco Pump of the Day: Worthington D512 1.25x1x4
At Thelco, we know that compact doesn’t mean compromised. Today’s featured unit—the Worthington D512 1.25x1x4—proves that small-frame pumps can still deliver powerhouse performance. With a rugged all-iron build, this pump is ideal for tight installations where durability and flow consistency are critical.
