The BF series is a vertical, four throw frame, suited up to 60 HP motor driven direct-coupled drive range requiring multi-stage applications. The heavy duty cast iron frame is designed with minimal floor space footprint, one piece counter balanced ductile iron crankshaft, single piece crosshead and “I” section designed connecting rods which will give years of service.
