Axial piston pump.The A7VK axial piston variable-displacement pump is specifically designed for high-pressure pumping of polyol and isocyanate i·so·cy·a·nate n. Any of a family of nitrogenous chemicals that are used in industry and can cause respiratory disorders, especially asthma, if inhaled. used in making polyurethane. The feed channel is separated from the drive work chamber to allow high pressure filling for highly viscous fluid. The pump is capable of outlet pressures up to 3,625 psi (4,500 psi peak). Good volumetric efficiency Volumetric efficiency in internal combustion engine design refers to the efficiency with which the engine can move the charge into and out of the cylinders. More correctly, volumetric efficiency is a ratio (or percentage) of what volume of fuel and air actually enters the is achieved using a robust internal rotary group and proven axial tapered piston technology, according to according to prep. 1. As stated or indicated by; on the authority of: according to historians. 2. In keeping with: according to instructions. 3. the company. Precise metering of the pump displacement can be adjusted from 0 to 28.1 [cm.sup.3] using a manual adjustment with an integrated display in the handwheel. Once adjusted, the displacement can be locked to prevent accidental changes. The pump has a double shaft seal made with special material and a flushing chamber that helps identify any inboard Built in. Inboard devices are built into the main unit. Contrast with outboard. See onboard. seal leakage. Internal parts are made without non-ferrous metals for compatibility with polyurethane components. The pump housing is also treated through a special process for corrosion protection, according to the manufacturer. The A7VK can be used with or without a feed pump a force pump for supplying water to a steam boiler, etc. See also: Feed . (Bosch Rexroth) Circle 103 on card |
