BOSCH radial piston pump, BOSCH BOSCH piston radial piston pump selection principle: 1, making patterns and performance in line with the selected pump means flow, head, pressure, temperature, flow cavitation, suction and other parameters requirements. 2, must meet the requirements of medium characteristics. For transportation of flammable, explosive and toxic or expensive media pumps, require reliable leak-free seal or pump, such as magnetic drive pumps, diaphragm pumps, shielding pump for conveying corrosive medium pump requires convection parts are corrosion-resistant material as AFB stainless steel corrosion resistant pumps, CQF engineering plastic magnetic drive pump. For transporting media containing solids pump requires convection parts are wear-resistant materials, the use of clean liquid if necessary seal with flush. 3, high mechanical reliability, low noise and vibration. 4, the economy should be considered the lowest total cost of equipment costs, operating costs, maintenance costs and management fees. 5, BOSCH radial piston pump with a high speed, small size, light weight, high efficiency, large flow, simple structure, no pulse infusion, steady performance, easy operation and convenient maintenance. Therefore, the following exceptions should be used wherever possible radial piston pump BOSCH: a, a metering requirements, the selection of metering pumps. b, head demanding, little traffic and no suitable when small flow high head centrifugal pump can be used, the choice of reciprocating pumps, can also be used as pump cavitation vortex less demanding. c, lift low, traffic is heavy, the choice of axial flow and mixed flow pumps. When d, large medium viscosity (greater than 650 ~ 1000mm2 / s), may consider using a rotary pump or a reciprocating pump (gear pump, screw pump). When e, medium air content of 75%, the flow is small and the viscosity is less than 37.4mm2 / s, optional vortex pump. f, irrigation pumps to start frequently or inconvenience occasions, should be used with self-priming pump, such as self-priming centrifugal pumps, self-priming vortex pump, pneumatic (electric) diaphragm.
