Plunger metering pump working principle and scope of application
December 07 00:05:38, 2022
The plunger metering pump directly draws in and discharges the working medium (yellow) through the reciprocating motion of the plunger. Plunger metering pump includes valve pump and valveless pump. Valveless rotary piston metering pumps are receiving more and more attention and are widely used in the metering of high viscosity media such as syrups, chocolates and petroleum additives. Plunger pump head structure is simple, economical, high measurement accuracy, the need to select and maintain a good seal. Automatic lateral alignment between the plunger and the seal ensures minimal wear between the two. Plunger metering pump Scope of application: Plunger metering pump because of its simple structure and high temperature and pressure and other advantages have been widely used in the field of petrochemicals. Plunger material is stainless steel, ceramic oxide, ceramic oxide has high corrosion resistance and high hardness wear characteristics.
Sleeved plug valves are used for on/off and throttling service in corrosion process with media temperature , such as chemical industry, Sleeved plug valves are non-lubricated valvequarter turn valve that achieve sealing through the use of a compressible sleeve as a sealing member. The valve size is from 1/2" to 30" with matching valve pressure from class 150 to class 600. Valve material can be carbon steel, stainless steel, allou steel, duplex steel etc.
