Type and Specification Compilation Description

SJM Series Mechanical Diaphragm Metering Pump

The metering pump is a special reciprocating displacement pump, of which the discharge can be infinitely regulated between 0 and 100% to feed corrosive and non-corrosive liquid at a certain amount for the purposes of different process flows. It includes piston metering pump, hydraulic diaphragm metering pump and mechanical diaphragm metering pump. The products comply with GB/ T7782-2008 metering pump standard.

SJM series mechanical diaphragm metering pumps are extensively used in such industries and sectors as petroleum, chemical, water treatment, environmental protection, food, light industry, paper-making, pharmacy, dyeing and finishing, metallurgy and mining.
