243 HYPR314 HYPR314 Hydraulic Pumps Harken offers 1- and 2-speed pumps for hydraulic systems. Our 2-speed pump automatically shifts to the next speed when a preset point is reached. The 1-speed pump is a simpler alterna- tive but features the same high-quality components. 1-speed pumps are used for smaller and midsize hydraulic systems, usually on MVP or compact panels. 2-speed pumps are used on sys- tems with higher oil volume cylinders and need faster reaction time. They are also available on MVP panels. Pressure relief on 1- and 2-speed pumps is factory-set to a maximum of 5000 psi. Mounting patterns for all pumps are identical, making upgrades easy. An optional adhered isolation plate further improves load distribution by transferring torque directly to the mounting surface rather than the bolt holes when mounting without a face plate. Pumps have 7-degree splined shafts to ensure a tight fit and to allow the handle to be mounted at the sailor’s preferred pumping angle. Hydraulic Rotary Pumps Harken offers two sizes of multi-speed, pedestal-driven rotary pumps for Grand Prix race boats. Pumps are made of corrosion-resistant hard lube-anodized aluminum, with aluminum, titanium, and stainless-steel components. Both pumps are bi-directional and have the same displacement if rotated in either direction. All pumps include a non-return valve on the outlet to prevent backflow. 10 cc Pumps A female spline attaches these pumps directly to any Harken pedestal. Six double-stepped pis- tons save weight and feature connecting rods for piston return rather than springs. Three fasten- ers provide quick connect/disconnect mounting. The 10 cc pump shifts 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 auto- matic shift point, pumps can be shifted manually. Adjustable Cam Multiple Displacement Pump Developed for the America’s Cup foiling monohulls, these pumps allow adjustment of flow rates per available grinder input versus pre-set flow/pressure levels. The pump has two banks that may be adjusted by changing piston size with inserts along with different cam positions to allow for flow from 4.75 cc to 16.3 cc per revolution for each bank. Harken will help you determine which setup is best. If requirements change, Harken can upgrade the pump to a different set of pistons insert and cam position to meet them. The pump also has an option of a built-in shift block (manual or electric) making it a 2- or 3-speed pump. A remote shift option (manual or electric) is also available. Please contact Harken for more information. Optional isolation plates made of extremely resilient G10 improve load distribution by transferring torque directly to the mounting surface.
