Harken offers three sizes of multi-speed, pedestal-driven rotary pumps for Grand-Prix race boats 13.7 - 30.5 m (45 - 100'). They deliver oil faster, more efficiently, and with higher shift points than other pumps of comparable sizes. The 10 and 20 cc pumps shift from 1st to 2nd gear both automatically and manually, with automatic shift points determined by the maximum output of the grinders. If fewer crew are grinding, and not enough power is generated to reach the automatic shift point, pumps can be shifted manually—the 20 cc pump by simply reversing the pedestal handles; the 10 cc pump by using a pull-cord attached to a lever. Pumps are made of corrosion-resistant Hard Lube-anodized aluminum, with aluminum, titanium, and stainless steel components. All pumps include a non-return valve on the outlet to prevent backflow. These patented pumps have a 30 mm male input shaft. Male input shafts attach pumps to bevel boxes or pedestals and can mount remotely. Two banks of six pistons feature spring returns and large volume output. Spinning the pump in the opposite direction at a pressure lower than the automatic shift point manually shifts it into second gear.
